Issue while fetching Users data from Azure AD - java

I am trying to fetch users available in Azure AD. While fetching, http 401 Authentication Error Encountered and IOException caught on console. Following is the method through which I am trying to fetch data-
public String getUsers(String accessToken) {
URL url;
String line = "";
try {
System.out.println("\n\n***************Available Users ************\n");
url = new URL("https://graph.windows.net/" + tenant_id
+ "/users");
HttpURLConnection con = (HttpURLConnection) url.openConnection();
// Set the appropriate header fields in the request header.
con.setRequestMethod("GET");
con.setRequestProperty("api-version", "1.6");
con.setRequestProperty("Authorization", "Bearer " + accessToken);
con.setRequestProperty("Accept", "application/json;odata=minimalmetadata");
int responseCode = con.getResponseCode();
System.out.println("Responsecode : " + responseCode);
line=HttpClientHelper.getResponseStringFromConn(con,true);
System.out.println("Line data"+line);
/*if (responseCode == 200) {
reader = new BufferedReader(new InputStreamReader(con.getInputStream()));
} else {
reader = new BufferedReader(new InputStreamReader(con.getErrorStream()));
}
StringBuffer stringBuffer = new StringBuffer();
while ((line = reader.readLine()) != null) {
stringBuffer.append(line);
}*/
System.out.println(line);
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return line;
}


As I known, you can refer to Error Handling in OAuth 2.0 to check your issue.
Meanwhile, as #GauravMantri said, you also need to check the permission of Microsoft Graph for application in AAD, please see the figures below.

My code supported with http but not with the https. It shows that java.net.SocketException: Unexpected end of file from server

I tried to send a GET request to the server(containing the details about the devices) and take the response from it. Inside the response should be the details about the devices. Those details are device Id and device Type.
Follow is my code.
I had replaced the Id address by using xxx.xx... sorry about it.
I tried once in http port(8482).
This implementations is works for it. But actually I want to use this program for https port(8120)
Then what should I do for this code to taken the support of https
void callConfigEndPoint() {
String host = "xxx.xxx.xxx.xxx";
String httpPort = "8482";
String deviceToken = "7645221";
String USER_AGENT = "Mozilla/5.0";
String endpointUrl = "http://"+host+":"+httpPort+"/api/device-mgt-config/v1.0";
try {
URL urlObject = new URL(endpointUrl);
HttpURLConnection httpURLConnection = (HttpURLConnection) urlObject.openConnection();
httpURLConnection.setRequestMethod("GET");
httpURLConnection.setRequestProperty("token", deviceToken);
httpURLConnection.setRequestProperty("User-Agent", USER_AGENT);
BufferedReader in = new BufferedReader(new InputStreamReader(httpURLConnection.getInputStream()));
String inputLine;
StringBuilder response = new StringBuilder();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
JSONObject jsonObj = new JSONObject(response.toString());
String deviceId = jsonObj.get("deviceId").toString();
String deviceType = jsonObj.get("deviceType").toString();
System.out.println("deviceId =>" + deviceId);
System.out.println("deviceType =>" + deviceType);
} catch (IOException e) {
e.printStackTrace();
}
}
Please consider that, I had removed the import section from this

Java hangs with openConnection in new thread

I'm building an app which invoke in separate thread an API request to REST API. This app still hangs after invoking the call - no exception thrown.
I was trying a lot of methods to make an GET request from my Java app but none on them worked out.
class ThreadRunner {
public ThreadRunner() {
}
public static void main(String[] args) {
ThreadRunner threadRunner = new ThreadRunner();
threadRunner.startChecking();
}
public void startChecking() {
Thread thread = new Thread(new Runnable() {
#Override
public void run() {
APIUtils.sendGet("https://app01.mysimpledomain.abc/api/v2/user/1");
}
});
thread.setName("ThreadRunner");
//thread.setDaemon(true);
thread.start();
}
}
class APIUtils {
public static void sendGet(String url) {
try {
System.out.println("Before invoking my url...");
URL obj = new URL(url);
HttpURLConnection con = (HttpURLConnection) obj.openConnection();
// optional default is GET
con.setRequestMethod("GET");
// add request header
con.setRequestProperty("User-Agent", USER_AGENT);
int responseCode = con.getResponseCode();
System.out.println("\nSending 'GET' request to URL : " + url);
System.out.println("Response Code : " + responseCode);
BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
System.out.println( "response: " + response.toString() );
System.out.println(response.toString());
} catch (HttpStatusCodeException e) {
System.out.println( "HttpStatusCodeException e: " + e.getMessage() );
} catch (Exception e) {
System.out.println( "Exception e: " + e.getMessage() );
// LOG.error(e, e);
}
}
}
The messages stops after print "Before connection...". I should see the output from my API.
I want to say that api calls works from chrome / firefox / postman.
Edit:
With URL for method APIUtils.sendGet: http://www.google.com/search?q=mkyong works but with my API url hangs before
Edit2:
URL from my API works and gives a JSON in Chrome / Firefox / Postman.

It may throwing exception. write the code to catch particular exception and try to resolve it.
here is the working code
String url = "http://www.google.com/search?q=mkyong";
try {
URL obj = new URL(url);
HttpURLConnection con = (HttpURLConnection) obj.openConnection();
// optional default is GET
con.setRequestMethod("GET");
//add request header
con.setRequestProperty("User-Agent", USER_AGENT);
int responseCode = con.getResponseCode();
System.out.println("\nSending 'GET' request to URL : " + url);
System.out.println("Response Code : " + responseCode);
BufferedReader in = new BufferedReader(
new InputStreamReader(con.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
System.out.println(response.toString());
} catch (HttpStatusCodeException e) {
attempts++;
} catch (Exception e) {
LOG.error(e, e);
}

HttpUrlConnection BadRequest - Statuscode 400

I have implemented a class using HttpUrlConnection to get some data from the google geocoding api. When I'm using this code on android, it works properly. But as soon as I am using this code in another "normal" java program, I am getting the status-code 400 (BadRequest) sometimes. Here is my code:
HttpURLConnection c = null;
StringBuilder sb = new StringBuilder();
try {
URL u = new URL(url);
c = (HttpURLConnection) u.openConnection();
c.setRequestMethod("GET");
c.setRequestProperty("Content-length", "0");
c.setUseCaches(false);
c.setAllowUserInteraction(false);
c.setConnectTimeout(timeout);
c.setReadTimeout(timeout);
c.connect();
int status = c.getResponseCode();
switch (status) {
case HttpURLConnection.HTTP_OK:
case HttpURLConnection.HTTP_CREATED:
BufferedReader br = new BufferedReader(new InputStreamReader(c.getInputStream()));
String line;
while ((line = br.readLine()) != null) {
sb.append(line + "\n");
}
br.close();
}
} catch (SocketTimeoutException ex){
// Handle ...
} catch (MalformedURLException ex) {
// Handle ...
} catch (IOException ex) {
// Handle ...
} finally {
if (c != null) {
try {
c.disconnect();
} catch (Exception ex) {
}
}
}
I have a reliable internet connection and also the URL I am using to receive the data works, whenever I try it with my web browser.
Thanks in advance!

Bad Request is often caused by inadequat URLs. As you mentioned not every URL gives this error, only a view of them. So it has to be something to do with that. Try the following code to ensure the correct encoding of the URL you are using:
String url = ...; // your url
url = URLEncoder.encode(url,"UTF-8");
// Use 'url' ...

HTTP Request to Wikipedia gives no result

I try to fetch HTML per Code. When fetching from "http://www.google.com" for example it works perfect. When trying to fetch from "http://en.wikipedia.org/w/api.php" I do not get any results.
Does someone have any idea ?
Code:
String sURL="http://en.wikipedia.org/w/api.php?action=query&generator=categorymembers&gcmtitle=Category:Countries&prop=info&gcmlimit=500&format=json";
String sText=readfromURL(sURL);
public static String readfromURL(String sURL){
URL url = null;
try {
url = new URL(sURL);
} catch (MalformedURLException e1) {
e1.printStackTrace();
}
URLConnection urlconnect = null;
try {
urlconnect = url.openConnection();
urlconnect.setRequestProperty("User-Agent","Mozilla/5.0 (Windows NT 5.1; rv:19.0) Gecko/20100101 Firefox/19.0");
} catch (IOException e) {
e.printStackTrace();
}
BufferedReader in = null;
try {
in = new BufferedReader(new InputStreamReader(urlconnect.getInputStream()));
} catch (IOException e) {
e.printStackTrace();
}
String inputLine;
String sEntireContent="";
try {
while ((inputLine = in.readLine()) != null) {
System.out.println(inputLine);
sEntireContent=sEntireContent+inputLine;
}
} catch (IOException e) {
e.printStackTrace();
}
try {
in.close();
} catch (IOException e) {
e.printStackTrace();
}
return sEntireContent;
}

It looks like the request limit. Try to check the response code.
From the documentation (https://www.mediawiki.org/wiki/API:Etiquette):
If you make your requests in series rather than in parallel (i.e. wait
for the one request to finish before sending a new request, such that
you're never making more than one request at the same time), then you
should definitely be fine.
Be sure that you do not do few request at a time
Update
I did verification on my local your code - you are correct it does not work. Fix - you need to use https, so it would work:
https://en.wikipedia.org/w/api.php?action=query&generator=categorymembers&gcmtitle=Category:Countries&prop=info&gcmlimit=500&format=json

The reason you didn't receive the response back is due to a HTTP Redirect 3XX. Wikipedia redirects your HTTP Request. Please try the below source code to fetch Response from Redirected URL. Please refer How to send HTTP request GET/POST in Java

How to connect to MovieDB API webservice?

I am new to webservice and I am in the learning phase. Not much of the online content gives information about the use of MovieDB API webservice. Well for not I am just focusing on trying to get a movie information on the screen.
So the as per the API I am requesting the information and I am getting the JSON response when I paste http://api.themoviedb.org/3/movie/550?api_key=MYKEY in the browser.
I want to write a webservice using JAVA,SOAP to parse the JSON and fetch the required information. I tried using HttpURLConnection and then use BufferedReader but its not working.
Kindly suggest me some better options. Any links/blogs will be helpful.
This is the code snippet.
public class TestJSON {
/**
* #param args
*/
public static void main(String[] args) {
try{
URL url = new URL("http://api.themoviedb.org/3/movie/550?api_key=MYKEY/3/movie/550");
HttpURLConnection con = (HttpURLConnection) url.openConnection();
con.setDoOutput(true);
con.setRequestMethod("GET");
con.setRequestProperty("Content-Type", "application/json");
String input = "";
OutputStream os = con.getOutputStream();
os.write(input.getBytes());
os.flush();
if (con.getResponseCode() != HttpURLConnection.HTTP_CREATED) {
throw new RuntimeException("Failed : HTTP error code : "
+ con.getResponseCode());
}
BufferedReader br = new BufferedReader(new InputStreamReader((con.getInputStream())));
String output;
System.out.println("Output from Server .... \n");
while ((output = br.readLine()) != null) {
System.out.println(output);
}
con.disconnect();
}
catch(MalformedURLException m){
System.out.println("Malformed URL");
}
catch(IOException ioe){
System.out.println("IO exception");
}
}
}
Thanks in advance.

Try this code to read the output from the url:
BufferedReader in = new BufferedReader(
new InputStreamReader(conn.getInputStream()));
String inputLine;
StringBuffer html = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
html.append(inputLine);
}
in.close();
