Edit:
After doing some more experimentation, I discovered that the request will only work if all of the values are quoted in the JSON string. That is to say that this won't work
{"Text":"test","RatingValue":0.0,"LocationID":5}
and this will
{"Text":"test","RatingValue":"0.0","LocationID":"5"}
What I don't understand is why. The first string seems to be a valid JSON string. Is this a quirk with WCF?
Original Post
I am trying to post a new item to a collection from android. I keep getting a response code of 400: Bad Request. I don't understand what I'm doing wrong and I was hoping someone might be able to help me. Here is the java code.
HttpURLConnection conn = (HttpURLConnection) uri.toURL().openConnection();
conn.setRequestProperty("Content-Type", "application/json; charset=utf-8");
conn.setRequestProperty("Accept", "application/json");
conn.setRequestProperty("User-Agent", userAgent);
conn.setChunkedStreamingMode(0);
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setRequestMethod("POST");
conn.connect();
DataOutputStream out = new DataOutputStream(conn.getOutputStream());
out.write(data.getBytes());
out.flush();
int code = conn.getResponseCode();
String message = conn.getResponseMessage();
conn.disconnect();
The data is a JSON string that looks like the following:
{"Text":"test","RatingValue":3.0,"ReviewID":0,"LocationID":5}
In this case the ReviewID is the primary key.
The URL for the request points to the collection of Ratings. If i paste the same location into my browser, it successfully queries the collection. It looks something like this:
http://localhost/DataService.svc/Ratings
try this :
HttpClient hc = new DefaultHttpClient();
HttpPost hp = new HttpPost("http://localhost/DataService.svc/Ratings");
HttpResponse hr;
JSONObject jo1 = new JSONObject();
joobject.put("Text", "test");
joobject.put("RatingValue", "3.0");
joobject.put("ReviewID", ".0");
joobject.put("LocationID", ".5");
StringEntity se = new StringEntity(joobject.toString(),HTTP.UTF_8);
se.setContentType("application/json");
hp.setEntity(se);
hr = hc.execute(hp);
maybe helpful
