How do I read Distance Matrix API response in JSON from my app?

String url = "https://maps.googleapis.com/maps/api/distancematrix/json?origins="+expedTextView.getText().toString()+"&destinations="+destTextView.getText().toString()+"&sensor=false&mode=driving&key=AIzaSyC9BT3f2jmmPSJh2ewGfGiuVz1zeIfPX4A";
HttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpGet httpGet = new HttpGet(url);
HttpResponse response = null;
try {
response = httpClient.execute(httpGet, localContext);
} catch (IOException e) {
e.printStackTrace();
}
Toast.makeText(SecondScreen.this, ""+response, Toast.LENGTH_LONG).show();
}
This is my code. I've tried to make an HTTP request suing this URL which constructs just fine, but, when I read the response, it doesn't look like JSON at all. Below is the code from response. Notice that the link works well when I put it in my browser.
HTTP/1.1 200 OK [Content-Type: application/json; charset=UTF-8, Date: Fri, 11 Jan 2019 14:26:57 GMT, Expires: Sat, 12 Jan 2019 14:26:57 GMT, Cache-Control: public, max-age=86400, Server: mafe, X-XSS-Protection: 1; mode=block, X-Frame-Options: SAMEORIGIN, Server-Timing: gfet4t7; dur=91, Alt-Svc: quic=":443"; ma=2592000; v="44,43,39,35", Accept-Ranges: none, Vary: Accept-Language,Accept-Encoding, Transfer-Encoding: chunked] cz.msebera.android.httpclient.conn.BasicManagedEntity#2bffe96

android : Invalid authorisation header in http get response

I have tried all possible ways to get correct JSON response from the below microsoft health API url. But its always giving me the "Invalid Authorisation Request" in the JSON response. I have tried Base64 encoding of authorisation token also but its not responding. I don't know where i am going wrong ?

String json_string = EntityUtils.toString(response.getEntity());

I think you should check the access token again to make sure it's valid. Because I use the new token in your question, reponse still 401.

After sending HTTP request to server sometimes I get status 302 (redirect)

I try to send POST request to some server with json parameters and I wait json response.
From Android it works fine but from Linux I get status 302 redirect. I really don't know where is my problem.
Here is command from linux:
curl -i -X POST --data "id=105&json={\"orderBy\":0\"maxResults\":50}" "http://mysite.com/ctlClient/"
And I get response:

}

}

return;
}
} else {
return;
}
} catch (Exception e) {
}
if (httpclient != null) {

}
}
access log on Android response:

"GET /fwf/online/ HTTP/1.1" 200 13981 "-" "Apache-HttpClient/4.1 (java 1.5)"
We can see that on POST server redirects me to /fwf/online/
From Wireshark i get the same results from both methods:
POST /ctlClient/ HTTP/1.1
User-Agent: Apache-HttpClient/4.1 (java 1.5)
Content-Type: application/x-www-form-urlencoded
Content-Length: 301

Connection: Keep-Alive
Why it works from Android but not from Linux with CURL?
Can anybody help me or give me direction how can i solve it?
Thank you

You want to add -L to your curl command. See http://curl.haxx.se/docs/faq.html#How_do_I_tell_curl_to_follow_HTT.

Android: HTTP POST response - 401

I have faced with one problem - returning 401 error msg when you already signed in and trying to get access to another secured pages. The mystic of this problem for me is that I can get access to another secured pages after you are signed in if check it via Firefox RestCLient or via iOS app but cannot get access via Chrome Advanced Rest Client and Android app. However, content-type and other necessary params are set the same in both web tools and apps. I have tried to set different auth headers with encoded login:pass but it doesnt help and it doesnt need because it should work without it, I think(at least FF and iOS app work without this header). What`s gonna be wrong?

That is my peace of Restful code in Android app:
public String serverRequest(int action, Bundle params) {
if (action == 0) {
if (Const.DEBUG_ENABLED)
Log.e(TAG, "You did not pass action.");
return "You did not pass action.";
}
try {
HttpRequestBase request = null;
HttpPost postRequest = null;
switch (action) {
case SIGN_IN:
request = new HttpPost();
request.setURI(new URI(SIGNIN_URL));
request.setHeader("Content-Type", "application/x-www-form-urlencoded; charset=utf-8");
postRequest = (HttpPost) request;
if (params != null) {
UrlEncodedFormEntity formEntity = new
UrlEncodedFormEntity(paramsToList(params));
postRequest.setEntity(formEntity);
}
break;
case SIGN_OUT:
request = new HttpPost();
request.setURI(new URI(SIGNOUT_URL));
request.setHeader("Content-Type", "application/x-www-form-urlencoded; charset=utf-8");
break;
case BANK_CARD_VERIFY:
request = new HttpPost();
request.setURI(new URI(BANK_CARD_VERIFY_URL));
request.setHeader("Content-Type", "application/x-www-form-urlencoded; charset=utf-8");
postRequest = (HttpPost) request;
if (params != null) {
UrlEncodedFormEntity formEntity = new UrlEncodedFormEntity(paramsToList(params));
postRequest.setEntity(formEntity);
}
break;
}
if (request != null) {
DefaultHttpClient client = new DefaultHttpClient();
if (Const.DEBUG_ENABLED)
Log.d(TAG, "Executing request: " + actionToString(action) + ": " + urlToString(action));
HttpResponse response = client.execute(request);
StatusLine responseStatus = response.getStatusLine();
int statusCode = responseStatus != null ? responseStatus.getStatusCode() : 0;
Log.d(TAG, "Status code: " + statusCode);
}
}
(sign in and sign out are public, bank_verify is secured page. Android app has the same response headers like chrome). It seems there is something problem with session or something else but I`m not sure exactly.
EDIT:
It seems I have found what`s the problem here. In Android app I create a new HttpCLient object due to it all old data is losed. But another question - how to make this HttpCLient reusable?

Problem found. I reuse httpClient everytime in spite of that to use only one which has all session data everytime. Just implement if statement to check if I have already httpclient object then you it otherwise create a new.

Android HttpPost failes - server receives null query string parameter

I have a simple WCF web service on my machine which I have developed to serve Android and IOS devices.
The service has a single method as following :
[OperationContract]
[WebInvoke(RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped, UriTemplate = "/?message={message}")]
string ServiceMessage(string message);
I have 3 clients , one .NET test client using HttpWebRequest which works fine , one IOS client which works fine and one Android client which I have developed with the HttpPost and HttpClient classes that fails.
Using Fiddler reverse proxy I have debugged the output of the .net client :
POST http://127.0.0.1:8888/Service1.svc/?message=_|JSON MESSAGE BODY|_HTTP/1.1
Content-Type: application/json; charset=utf-8
Host: 127.0.0.1:8888
Content-Length: 338
Expect: 100-continue
Connection: Keep-Alive
_|JSON MESSAGE BODY|_
On the other hand , this is the output of the Android HTTP Post :
POST http://10.0.2.2:8888/Service1.svc/ HTTP/1.1
Content-Type: application/json; charset=utf-8
Content-Length: 139
Host: 10.0.2.2:8888
Connection: Keep-Alive
User-Agent: Apache-HttpClient/UNAVAILABLE (java 1.4)
Expect: 100-Continue
message=_|JSON MESSAGE BODY|_
As you can see , .Net puts the message parameter on the Post at the top and does not
put the message variable name at the bottom while Android does not put the message body at the Post at the top and does put the message variable name at the bottom.
This is my Android post code ,
HttpPost httpPost = new HttpPost(url);
String messageBody = "message=" + jsonMessageParameter;
StringEntity entity = new StringEntity(messageBody);
httpPost.setEntity(entity);
httpPost.setHeader("Content-Type", "application/json; charset=utf-8");
HttpResponse response = hc.execute(httpPost);
InputStream content = response.getEntity().getContent();
String json = ConvertStreamToString(content);
When calling with this code , the server method is called but the message method parameter is null.
I tried playing with the Uri.Builder class to also make the android post put the message at the header , but doesnt quite work.
If can someone help me out here , I am stuck on this for hours over hours.
Thank you in advance ,
James
EDIT :
I changed the Android code to :
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
nameValuePairs.add(new BasicNameValuePair("message", jsonMessageParameter));
HttpPost httpPost = new HttpPost(url);
UrlEncodedFormEntity urlEncodedFromEntity = new UrlEncodedFormEntity(
nameValuePairs);
urlEncodedFromEntity.setContentType(new BasicHeader("Content-Type",
"application/json; charset=utf-8"));
httpPost.setEntity(urlEncodedFromEntity);
InputStream postStream = httpPost.getEntity().getContent();
String postOutput = ConvertStreamToString(postStream);
HttpResponse response = hc.execute(httpPost);
InputStream content = response.getEntity().getContent();
String json = ConvertStreamToString(content);
But still the Fiddler monitoring is as following :
POST http://10.0.2.2:8888/Service1.svc/ HTTP/1.1
Content-Length: 189
Content-Type: application/json; charset=utf-8
Host: 10.0.2.2:8888
Connection: Keep-Alive
User-Agent: Apache-HttpClient/UNAVAILABLE (java 1.4)
Expect: 100-Continue
message=_|MESSAGE_JSON|_

There a number of points here.
First, you specifically added message= to your Android POST body:
String messageBody = "message=" + jsonMessageParameter;
This can be also problematic since you specified Content-Type: application/json but by adding message= you are not providing a valid JSON object.
Second, why does the .Net implementation replicate the JSON object both as parameter in the URL and in the body? This looks strange and very uncommon for a POST request, and can cause problem if your JSON object makes the URL exceed the maximum URL length.
So I would try removing message= in the body and removing the JSON object as a URL parameter, since servers processing POSTs should read the body and not the URL.

HttpPost is for posting, afaik.
String url;
input = url + URLEncoder.encode(messageBody, "utf-8");
HttpClient httpclient = new DefaultHttpClient();
HttpGet httpget = new HttpGet(input);
InputStream stream = httpclient.execute(httpget).getEntity().getContent();
String s = streamToString(stream);
JSONObject jObject = new JSONObject(s);
This very exact code (plus some try/catch) works for me for querying GoogleBooks, probably you can adapt it to your service with little effort?
Best regards.
