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

I am a newbie to HttpClient so not sure what's wrong I am doing. I am hitting one POST request through HttpUrlConnection. After sending the request when I check the logs it doesn't hit the entire request. My URL is https://www.example.com/product/pd/v1/gql when I check on the server, for URI, it shows v1/gql and give 400 error. while the same request works perfectly from Postman and advance rest client.
URL obj = new URL("https://www.example.com/product/pd/v1/gql/");
HttpURLConnection conn = (HttpURLConnection) obj.openConnection();
conn.setRequestMethod("POST");
conn.setRequestProperty("User-Agent", USER_AGENT);
conn.setDoOutput(true);
conn.setRequestProperty("Content-Type", "application/json");
conn.setRequestProperty("Cookie", "_bb_vid=djfhhf");
JSONObject val = new JSONObject(gqlValue2);
JSONObject jObj = new JSONObject();
jObj.put(gqlKey1, gqlValue1);
jObj.put(gqlKey2, val);
System.out.println(jObj);
OutputStreamWriter wr = new
OutputStreamWriter(conn.getOutputStream());
wr.write(jObj.toString());
wr.flush();
I want to send a POST request to my NodeJS/Express API with some JSON data. I managed to make GET requests with no problem. Here's what I do for a POST request:
URL u = new URL(url);
JSONObject jsonObject = new JSONObject();
jsonObject.put("nombre", "testing");
c = (HttpURLConnection) u.openConnection();
c.setDoOutput(true);
c.setRequestMethod("POST");
c.setRequestProperty("Content-length", Integer.toString(URLEncoder.encode(jsonObject.toString(),"UTF-8").length()));
c.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
c.setUseCaches(false);
c.setAllowUserInteraction(false);
c.setConnectTimeout(0);
c.setReadTimeout(0);
c.connect();
DataOutputStream printout = new DataOutputStream(c.getOutputStream ());
printout.writeBytes(URLEncoder.encode(jsonObject.toString(),"UTF-8"));
printout.flush ();
printout.close ();
int status = c.getResponseCode();
In my API, I have a console.log(req.body); to see what is my POST route getting, and this is what I get in my console:
Got this for POST:
{ '{"nombre":"testing"}': '' }
The whole JSONObject is sent as the key for the JSON object with an empty value on the HTTP POST request. Any ideas on what am I doing wrong? Thanks!
Try replace
c.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
with
c.setRequestProperty("Content-Type", "application/json");
and
printout.writeBytes(URLEncoder.encode(jsonObject.toString(),"UTF-8"));
with
printout.writeBytes(jsonObject.toString());
I am having issues creating a BC shipment against an existing order.
I am using Basic Authentication
JSON request is
{"order_address_id":2,"items":[{"order_product_id":164,"quantity":1},{"order_product_id":124,"quantity":1}],"tracking_number":"abcd1234"}
code is as follows:
String storeurl="storeaddress"+"/orders/"+BCordernumber+"/shipments";
URL url = new URL(storeurl);
HttpURLConnection httpcon = (HttpURLConnection) url.openConnection();
httpcon.setRequestMethod("POST");
httpcon.setRequestProperty("Authorization", encodeBase64());
httpcon.setRequestProperty("Accept", "application/json");
httpcon.setDoOutput(true);
httpcon.setRequestProperty("Content-Type", "application/json");
OutputStreamWriter put = new OutputStreamWriter(httpcon.getOutputStream());
put.write(jsondata);
put.flush();
put.close();
int result = httpcon.getResponseCode();
Any ideas would be great as to why I am getting this 400 error
Thanks
in advance
I have realised my mistake, I was using the product_id rather than the order_product_id.
All good
I'm overhauling certain parts of my app to use the new GCM service to replace C2DM. I simply want to create the JSON request from a Java program for testing and then read the response. As of right now I can't find ANY formatting issues with my JSON request and the google server always return code 400, which indicates a problem with my JSON.
http://developer.android.com/guide/google/gcm/gcm.html#server
JSONObject obj = new JSONObject();
obj.put("collapse_key", "collapse key");
JSONObject data = new JSONObject();
data.put("info1", "info_1");
data.put("info2", "info 2");
data.put("info3", "info_3");
obj.put("data", data);
JSONArray ids = new JSONArray();
ids.add(REG_ID);
obj.put("registration_ids", ids);
System.out.println(obj.toJSONString());
I print my request to the eclipse console to check it's formatting
byte[] postData = obj.toJSONString().getBytes();
try{
URL url = new URL("https://android.googleapis.com/gcm/send");
HttpsURLConnection.setDefaultHostnameVerifier(new JServerHostnameVerifier());
HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
conn.setDoOutput(true);
conn.setDoInput(true);
conn.setUseCaches(false);
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", "application/json");
conn.setRequestProperty("Authorization", "key=" + API_KEY);
System.out.println(conn.toString());
OutputStream out = conn.getOutputStream();
// exception thrown right here. no InputStream to get
InputStream in = conn.getInputStream();
byte[] response = null;
out.write(postData);
out.close();
in.read(response);
JSONParser parser = new JSONParser();
String temp = new String(response);
JSONObject temp1 = (JSONObject) parser.parse(temp);
System.out.println(temp1.toJSONString());
int responseCode = conn.getResponseCode();
System.out.println(responseCode + "");
} catch(Exception e){
System.out.println("Exception thrown\n"+ e.getMessage());
}
}
I'm sure my API key is correct as that would result in error 401, so says the google documentation. This is my first time doing JSON but it's easy to understand because of its simplicity. Anyone have any ideas on why I always receive code 400?
update: I've tested the google server example classes provided with gcm so the problem MUST be with my code.
{"collapse_key":"new-test-notification","data":{"info1":"info_1","info3":"info_3","info2":"info 2"},"registration_ids":["APA91bG3bmCSltzQYl_yOcjG0LPcR1Qemwg7osYJxImpSuWZftmmIjUGH_CSDG3mswKuV3AAb8GSX7HChOKGAYHz1A_spJus5mXFtfOrK0fouBD7QBpKnfc_ly0t3S8vSYWRjuGxtXrt"]}
I solved it using a different approach so it must have been my original implementation.
List<NameValuePair> list = new ArrayList<NameValuePair>();
list.add(new BasicNameValuePair("username",username));
list.add(new BasicNameValuePair("deviceId",regId));
list.add(new BasicNameValuePair("deviceType","AndroidPhone"));
DefaultHttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("example.url.com");
post.setEntity(new UrlEncodedFormEntity(list));
ResponseHandler<String> handler = new BasicResponseHandler();
HttpResponse response = client.execute(post);
String responseString = handler.handleResponse(response);
JSONObject jsonResponse = new JSONObject(responseString);
I'm reading here that you should use your 'Key for browser apps'
GCM with PHP (Google Cloud Messaging) (in comments)
Try to reproduce the error using curl or another command-line tool so we can eliminate the possibility that there's a bug in your java that we're all missing.
Here is my code:
String addr = "http://172.26.41.18:8080/domain/list";
URL url = new URL(addr);
HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
httpCon.setDoOutput(true);
httpCon.setDoInput(true);
httpCon.setUseCaches(false);
httpCon.setAllowUserInteraction(false);
httpCon.setRequestMethod("GET");
httpCon.addRequestProperty("Authorization", "Basic YWRtaW4fYFgjkl5463");
httpCon.connect();
OutputStreamWriter out = new OutputStreamWriter(httpCon.getOutputStream());
System.out.println(httpCon.getResponseCode());
System.out.println(httpCon.getResponseMessage());
out.close();
What I see in response:
500 Server error
I open my httpCon var, and what I see:
POST /rest/platform/domain/list HTTP/1.1
Why is it set to POST even though I have used httpCon.setRequestMethod("GET"); to set it to GET?
The httpCon.setDoOutput(true); implicitly set the request method to POST because that's the default method whenever you want to send a request body.
If you want to use GET, remove that line and remove the OutputStreamWriter out = new OutputStreamWriter(httpCon.getOutputStream()); line. You don't need to send a request body for GET requests.
The following should do for a simple GET request:
String addr = "http://172.26.41.18:8080/domain/list";
URL url = new URL(addr);
HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
httpCon.setUseCaches(false);
httpCon.setAllowUserInteraction(false);
httpCon.addRequestProperty("Authorization", "Basic YWRtaW4fYFgjkl5463");
System.out.println(httpCon.getResponseCode());
System.out.println(httpCon.getResponseMessage());

Unrelated to the concrete problem, the password part of your Authorization header value doesn't seem to be properly Base64-encoded. Perhaps it's scrambled because it was examplary, but even if it wasn't I'd fix your Base64 encoding approach.
