HTTPS Get String

Is it possible to use HTTPS (vs plain HTTP) in the HTTP GET String module?
I have configured my computer to connect to the Web UI itself via HTTPS, but when I try to fetch data via an embedded HTTP GET call, it returns a 404 not found error for any URL beginning with https://address.
(I have confirmed https://address is available via browser). It looks like maybe the HTTPS GET module does not support SSL?

Ryan, thanks for your response. But I think we are talking about two separate things. You show how LabView web *server* can do HTTPS. What I want to do is have the "HTTP GET" *client* in a WebUI fetch HTTPS data from a third party web server. Per the WebUI documentation, this is supported:
Can applications created using LabVIEW Web UI Builder applications communicate with non-LabVIEW web services?
Yes, LabVIEW Web UI Builder can communicate with both LabVIEW and non-LabVIEW web services. ... With non-LabVIEW web services, the user must implement the low-level HTTP and XML programming required to call the web service and parse the XML response.
Attached is a very simple example of a VI that works for HTTP but fails for HTTPS. (The same URL works in a browser for both HTTP and HTTPS). In this simple example the web server is Tomcat running on localhost.

HTTP GET only works once

Web UI Builder:
I have a device that responds to HTTP GET messages.
I made a simple vi that uses the HTTP GET String function connected to a string constant and WireShark to monitor Ethernet traffic.
When the vi is first run an HTTP message is sent and replied to.
If the vi is run again the message is not transmitted.
If the HTTP GET message is changed the new message will be transmitted. But not twice.
If LabVIEW Web UI Builder is closed and restarted the message will again be sent just once when run.
Why is the message only being sent once? It's like all outgoing messages are being tracked and only sent once.

I think this is standard (but not always desirable) behavior of the networking stack that Web UI Builder uses. (On Windows, it's basically the built in/ Internet Explorer networking stack). After the first GET request with the same URL, if the server doesn't send no-cache headers, a cached result will be returned.
If you control the server that you're connecting to (and can add HTTP headers), try adding a no-cache header to the GET response. ("Cache-Control: no-cache" is the first one I'd try).
If you don't control the server you're connecting to / that doesn't work, another workaround is to append a query string parameter with a random number or timestamp. With this approach, the GET URL is always changing, so the caching behavior is disabled and the request should always go to the server.
(Something like this appended to the end of the URL:
or, "&n=[timeInTicks]" if you're already using other query parameters)

Authentication syntax for HTTP GET method using TCP functions in Labview on linux

Hi,
Currently, I am trying to communicate to web server. I have Labview installed on a Linux machine. The HTTP function blocks and other labview functions do not work. Hence, I am building a HTTP code string using TCP functions (port 80) to talk to the web server. I am successfully able to fetch a response from web sites (example www.ni.com) from my vi. However, when I try to communicate to my web server, it does not work. It requires an authentication. I am able to open http://ipaddress in my browser from my machine using username and password. Can someone help with Authentication string requirement for GET method?
so far the string is:
GET /index/ HTTP/1.1
Host: http://xx.xx.xx.xx

An easy option would be to try http://userassword@server syntax for the URL.
Else I posted a Twitter fetcher once (won't work anymore since Twitter moved to Oauth authentication) at LAVA. Based on code from @cloew.
The code is part of this LLB.

R/3 HTTP GET to external supplier - what are the options

Hello all
Our scenario is that we have to connect to an external supplier using HTTP GET to get our order responses in the return structure. I was wondering what the best/easiest way is to do this.
We cannot use the HTTP adapter since that only supports HTTP-POST. Additionally the RFC that lies behind it does not allow query strings in the definition, something we need to use.
we could make use of the HTTP_GET function module in the SFTP function group but how to do it then?
-we cannot create an abap proxy for this since the outbound WSDL contains invalid keywords (choice keyword not supported)
-we probably could use BPM that calls the HTTP_GET.
-we could write an ABAP that calls the HTTP_GET and puts the output into a directory where XI can pick it up.
-I also read that you could write a small java function that does the HTTP_GET . But i have no experience with this.
So what is the best option to accomplish this?
thanks
Tom

From SP15 you may use Adapter-Specific Message Attributes.
To evaluate adapter attributes in the message header of the XI message, set the Use Adapter-Specific Message Attributes indicator.
     If you want missing message attributes to trigger an error message, set the Fail If Adapter-Specific Message Attributes Missing indicator. If the indicator is set and the header for adapter-specific message attributes or one of the set attributes is missing from the message, this leads to a system error (red flag).
If you do not set the indicator, and message attributes are missing, the adapter accesses information from the adapter configuration.
     If you want to use an HTTP destination or URL set by the mapping, set the URL or HTTP Destination indicator. (The indicator displayed depends on the Addressing Type you selected above). If you set the indicator, the URL or HTTP destination set dynamically is called by HTTP.
If the message header does not contain the URL or the HTTP destination, and you have set the Fail If Adapter-Specific Message Attributes Missing indicator, the XI message is set to status System Error. If you do not set the indicator, the URL or HTTP destination defined statically in the communication channel is used.
     If you want to use HTTP Header Fields, set the indicator and enter the fields in Field 1 to Field 6. The fields are embedded in the HTTP request under the names you enter here.
The technical names of the fields are HeaderFieldOne, .... HeaderFieldSix.
     If you want to use URL Parameters, set the indicator and enter the parameters in the fields Parameter 1 to Parameter 6. The parameters are embedded in the HTTP request under the names you enter here.
The technical names of the fields are URLParamOne, c, URLParamSix.
The attribute namespace for the adapter is http://sap.com/xi/XI/System/HTTP.

OSB proxy for HTTP GET servlet

Hello,
I need to create a proxy in OSB that will accept HTTP/GET requests (with ?param1=value1&param2=value2.... parameters).
My goal is simply to forward this request to another servlet in J2EE instance that will actually serve the request and send back to OSB the text/xml response.
Can you please point me to the correct proxy and business service configuration for this?
Our SOA version is 10.3.6 and we have OSB and J2EE servers in our domain.
Thanks

Hello again,
I found the solution so I will share it with you in case someones needs it the future.
I created a business service with Service Type "Messaging service", request message type "none", response message type "text" and Http transport "GET".
I created a proxy service with Service Type "Messaging service", request message type "text", response message type "text". I created a routing node my flow directed to the business service mentioned above. In the routing pipeline request i put the following actions:
1) Assign:
Expression $inbound/ctx:transport/ctx:request/http:query-string/text()
variable queryString
to assign the inbound query string in a variable
2)Insert
expr: fn-bea:inlinedXML('<http:query-string xmlns:http="http://www.bea.com/wli/sb/transports/http"></http:query-string>')
location: as first child
Xpath: ./ctx:transport/ctx:request
in variable: outbound
3)insert
expr: $queryString (created in step 1)
location: as first child
Xpath: ./ctx:transport/ctx:request/http:query-string
in variable: outbound
Now the query string should be redirected properly to your business service/ GET servlet.

I got the soluntion
we just need to change the binding in WSDL file from Soap to HTTP.
First of all add three namespaces in wsdl file
xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/"
xmlns:http="http://schemas.xmlsoap.org/wsdl/http/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
Then change the Request msg from element type to string type like below
<message name="UserLoggOffRequestMessage">
<part name="UserId" type="xsd:string"/> (add this one))
(remove this one)
</message>
Then change the binding
<binding name="UserLoggOffBinding" type="client:UserLoggOff">
<http:binding verb="GET"/>
<operation name="process">
<http:operation location="/process"/>
<http:urlEncoded/>
<output>
<mime:mimeString part="Body"/>
</output>
</operation>
</binding>
Then do some changes in service tag . we need to do the changes in location only.
we need to remove orabpel from location and add httpbinding
http://infva04718.vshodc.lntinfotech.com:8888/*orabpel*/MobileApplication/UserLoggOff/1.0
http://infva04718.vshodc.lntinfotech.com:8888/*httpbinding*/MobileApplication/UserLoggOff/1.0
do like following
<service name="UserLoggOff">
<port name="UserLoggOffPort" binding="client:UserLoggOffBinding">
<http:address location="http://infva04718.vshodc.lntinfotech.com:8888/httpbinding/MobileApplication/UserLoggOff/1.0"/>
</port>
</service>
Then deploy the process then u can invoke this
http://infva04718.vshodc.lntinfotech.com:8888/httpbinding/MobileApplication/UserLoggOff/process?UserId=a1
here process is name of process u want to invoke

SOAP Server - HTTP GET

Good afternoon, I'm trying to test my class:
public String getOperation(String methodName, String[] paramNames, Object[] paramValues) throws Exception
int size = 0;
          int i = 0;
          // Crear el stub cuando no exista
          if (!estado)
     prepareStub();
//Invoca un método de un servicio Web
          WebServiceMethod wsm = wsp.getMethod(methodName); //WebServiceProxy
          // Falta establecer los parámetros, aquí es donde se envían los parámetros
size = paramNames.length;
          String[] inMsgPartNames = new String[size];
          Object[] inMsgPartValues = new Object[size];
          for(i = 0; i < size; i++)
               inMsgPartNames[i] = paramNames;
               inMsgPartValues[i] = paramValues[i];
          //Object objRet = wsm.invoke(inMsgPartNames,inMsgPartValues);
          //String resp = (String)objRet;
String resp = "";
          return resp;
I want to invoke dynamically a Web Service, but I get this SOAP message
<html><head><title>SOAP Server</title></head>
<body><h1>SOAP Server</h1>
<p>Sorry, I don't speak via HTTP GET- you have to use
HTTP POST to talk to me.</p></body></html>
Could you tell me. how can I test my class, with a local Web Service?

Hi Veronica,
I had the same problem yesterday. The "magic" is getting the URL right. If you look at the deployment information you will see that the test URL is something like http://localhost:8888/Workspace1-ModelWebService-context-root/JavaClass1 (my test class was JavaClass1). You can change the URL relative address, but the default will be what is shown.
Best,
Joe

Is it possible to use HTTP GET navigation links?

Hi,
I'm learing JSF technology, I found it very powerful.
But I'm not able to understand how generate navigation links that use HTTP GET method. Do anyone Help me?
It seems impossilbe, but I don't want believe that it is true.
Building a web site using only HTTP POST methods is out of the W3C for Web Site suggestions.
A "good" serach engine for example dosen't take in cosideration HTTP POST Links.
I hope that someone tell me how generate using JSF HTTP GET links for navigation.
Bye

Balusc, thanks for you help.
The blog is very good!
I make help classe (FacesUtils) who you show in blog, but not find the property on request context map, but I use the param variable on faces-config.xml and Request Managed Bean and all work fine.
thanks.
I'm wrong where I think the Request Managed Bean is create for each request on all pages, the Request Managed Bean is create only on requeste page reference its.
Parte of my faces-config where I put the Request Managed Bean:
<managed-bean>
          <managed-bean-name>uuidParamManager</managed-bean-name>
          <managed-bean-class>
               br.srv.full.virtual.managers.request.UUIDParamManager
          </managed-bean-class>
          <managed-bean-scope>request</managed-bean-scope>
               <managed-property>
               <property-name>loginManager</property-name>
               <property-class>
                    br.srv.full.virtual.managers.LoginManager
               </property-class>
               <value>#{loginManager}</value>
          </managed-property>
          <managed-property>
               <property-name>uuid</property-name>
               <property-class>java.lang.String</property-class>
               <value>#{param.UUID}</value>
          </managed-property>
     </managed-bean>Where UUIDParamManager is create on request its receive first the LoginManager Instance, and later its receive the UUID param.
I put the prototype of project on virtual.full.srv.br.

Howto start a bpel process by using a http-get browser request

Hi,
i need some help with the start of a bpel-process.
My process will be started by a receive-activity which comes from a http-get browser request. Then the process will redirect the request-string to a synchronous service to get back its response to process it (this service has of course a wsdl).
The initial receive-activity needs a port Type and an operation to be declared. These concrete binding declarations must be defined in a wsdl-document i think. But the browser-client has no wsdl (and doesnt need it since it is no webservice, i think). Where do i declare the operation, port Type, etc.? Is it possible that it will be declared in an extra WSDL which represents the bpel-process?
Any help would be appreciated.

Intro to HTTP GET

I am obviously missing something very basic in performing an HTTP GET of a file on a SunONE virtual server. Below is the code, which consistently retrieves the index.html at the root directory, regardless of the HTTP GET that I send via the output stream before reading the input stream. Would appreciate advice or vectors to sample code. Thanks.
/import java.net.*;
import java.io.*;
public class HttpDemo
private static String protocol = "http";
private static String serverIP = "216.177.44.46";
private static int serverPort = 7020;
private static String fileName = "SSP700A.pdf";
public static void main(String[] args)
try
URL url = new URL(protocol + "://" + serverIP + ":" + serverPort);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setDoOutput(true);
BufferedOutputStream bos = new BufferedOutputStream(conn.getOutputStream());
DataOutputStream dos = new DataOutputStream(bos);
dos.writeChars("GET /" + fileName + " HTTP/1.1\r\n");
dos.flush();
dos.close();
bos.close();
BufferedInputStream bis = new BufferedInputStream(conn.getInputStream());
DataInputStream dis = new DataInputStream(bis);
String fromServer;
while ((fromServer = dis.readLine()) != null)
System.out.println(fromServer);
dis.close();
bis.close();
catch (MalformedURLException e)
e.printStackTrace();
catch (IOException e)
e.printStackTrace();
}

I don't think you need to form the HTTP request yourself.
I'm pretty certain that url.openConnection(); does all the HTTP requesting for you.
If I were to try to do what you're trying to do, I'd just do this:
URL url = new URL(protocol + "://" + serverIP + ":" + serverPort + "/" + filename);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
BufferedInputStream bis = new BufferedInputStream(conn.getInputStream());
...

Using ADFS authentication to perform SSO via HTTP GET request

Hi,
Can i authenticate users (those users are clients, at home) to a web application using ADFS without SAML tokens?
The situation is that i want the clients to perform SSO to the website via a link they receive in their mailboxes.
I thought about a solution that combines JWT in a URL link that each user will get to his private mail. this link will contain the users' claim (such as ID Num, given from AD DS Server dedicated especially for them).
Thus, the user will receive an email with a link that already contains a short period of time JWT to perform SSO to the webapp.
Is it possible ? anybody heard about a similar solution ?

Currently i have some data in ABAP structure with 5 fields, i need to create XML from the those 5 fields,and needs to be URI
encode it, and then needs to make a HTTP get request to connect Where to Get It REST API, finally it will return XML document via HTTP Get request , and then needs to convert the return XML to ABAP structure for further processing .the above 4 points will be implemented in my report.

How to get string value from xml in JSF??

In JSF How to get string value from xml, .ini and properties file. I want to get string value from xml or text to JSF

Just use the appropriate API's for that. There are enough API's out which can read/parse/write XML, ini and properties files. E.g. JAXP or DOM4J for xml files, INI4J for ini files and Sun's own java.util.Properties for propertiesfiles.
JSF supports properties files as message bundle and resource bundle so that you can use them for error messages and/or localization.

In the above code im geeting project D which is an integer value. But not able to get the project name.
Please some one guide me.

As I said in the other thread, this really isn't the place to ask questions about a database API unrelated to the Illustrator SDK. You're far more like to find people familliar with your problem on a forum that is dedicated to answering those kinds of questions instead.

Retrieve data from a non-peoplesoft application using HTTP Get

I need to retrieve data from a non-peoplesoft application. They want us to submit a HTTP GET request to their URL with a series of parameters. I am thinking about using HTTP Targert connector to accomplish this. Does anyone have sample peoplecode?
Currently we are on 8.51.10 Tools...
If there is any better way .. please let me know ..

I have used HTTP Get to get XML file from a government sanction list by hitting URL http://www.treasury.gov/ofac/downloads/sdn.xml
There is a delivered PS program that does that for vendor sanctions. I had to get the online setup correctly by creating a new custom Node with HTTP Target Connector. The program name is BSP_IMPORT. The below code is responsible for the calling the node and retrieving the data. Play around with the code below see if you can get it to meet your needs.
BSP_IMPORT_AET.BANKNODE.Value is just the custom external code that I created.
PMT_FLAT_FILE_INBOUND message is just a none rowset based message to use the web service call.
