500 Internal server error django java

Question

I am sending a Java post request(JSON object) from my Java app to my Django app(in same machine).

My code for java request part is:

    HttpClient client = new DefaultHttpClient();
    HttpPost post = new HttpPost(myurl);
    String json = jsonobject;

    StringEntity entity = new StringEntity(json,"UTF-8");
    entity.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
    post.setEntity(entity);
    try {
        HttpResponse response1 = client.execute(post);
        LOGGER.info("Reached " + response1);
    } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

And my Python views function is as follows:

@csrf_exempt
def rcvr1(request):
    if request.method=="POST":
        try:
            return StreamingHttpResponse("here")
        except:
            return StreamingHttpResponse("not Here")

    return StreamingHttpResponse("Unsuccessful")

The post request from Java is hitting the server, but is giving error:

HTTP/1.0 500 INTERNAL SERVER ERROR [Date: Wed, 07 Jan 2015 14:00:11 GMT, Server: WSGIServer/0.1 Python/2.7.6, X-Frame-Options: SAMEORIGIN, Content-Type: text/html]

It would be in the response, you could dump more from your java client but since it fails before even checking POST you could also check it with your browser via a GET — Daniel Rucci

You can't pass a string into StreamingHttpResponse, it needs to be a generator.

Until you make that change you can test the above by using an HttpResponse instead.

HttpResponse("Your text here")
