HTTP Request in post

Question

Hi all,
    I want to implement an interface between SAP and a bank.
    The bank provide a HTTP server, when I sent a HTTP request in post method with an XML body to the server, it will answer a response with an XML body to me.
    I search lots of topic about HTTP request in ABAP, then I know I must create a object ref to IF_HTTP_CLIENT, but I don't know which parameter I need to input, and how can I receive the response, and so on.....
    So, I want some simple code, can you help me? thanks in advance!
    PS: Does I need to configure a HTTP Adapter? I never use XI so I don't know any adapter, I just want to sent a request and receive a response in ABAP

Answer 1

you can use HttpURLConnection to POST or GET request in your backing bean
See this example
    public void youTubeServerAction(ClientEvent clientEvent) {
      URL               url;
      HttpURLConnection conn;
      StringBuffer strBuffer = new StringBuffer();
        try {
            url = new URL("http://gdata.youtube.com/feeds/users/thomasthiele/uploads?alt=json-in-script&callback=showMyVideos&max-results=50");
            conn = (HttpURLConnection) url.openConnection();
            conn.setDoOutput(true);
            conn.setRequestMethod("GET");                   // >> set here POST request
            InputStream in = conn.getInputStream();
            int c;
            while ((c = in.read()) != -1)
                strBuffer.append((char)c);
            System.out.println(strBuffer.toString());
            in.close();
            conn.disconnect();           
        } catch (Exception e) {
            e.printStackTrace();
        FacesContext fctx = FacesContext.getCurrentInstance();
        ExtendedRenderKitService serv =
            Service.getRenderKitService(fctx, ExtendedRenderKitService.class);
        System.out.println("SOURCE " + strBuffer.toString());
        serv.addScript(fctx, strBuffer.toString());       
    }Good luck.
