I am trying to work with the microsoft azure text analytics API but when I run this code with the correct keys I get a java.net.MalformedURLException on the endpoint key which itself is correct, but the error returns the key as xxxxxxxhttps. How do I get the code to run?
endpoint = "xxxxxxx";
URL url = new URL(endpoint+path);
The URL you end up with is "xxxxxxxhttps://northeurope.api.cognitive.microsoft.com/text/analytics/v2.1/languages".
Which is not a valid URL.

-As per my understanding I am not passing correct input.
Input needs to be URL encoded and I am sending it as JSON.
Kindly suggest and provide solution for the same.
After setting up the body correctly it worked
String urlParameters = ("grant_type="+grantType+"&username="+userName+"&password="+password);
OutputStream os = httpConn.getOutputStream();
byte[] postData = urlParameters.getBytes("utf-8");
int postDataLength = postData.length;
os.write(postData, 0, postDataLength);
We are executing web services using java code. The web service response comes in gzip format from the web service provider. We are unzipping the response using GZIPInputStream after receiving the response.
Response is converted into byte codes and then passing as input to gzipinputstream. This code is working fine in Eclipse and able to unzip the response string. The same code is not working in Linux and throwing the error "Not in Gzip format" while passing the byte array to gzipinputstream.
We checked the default charset in Windows is windows-1252 and in Linux is UTF-8. So, we tried to get the bytes in UTF-8 and windows-1252. Both are not working.
Can anyone please help me where is it going wrong and how to resolve the issue?
Tried changing the charset while generating the byte codes of the response.

I have a code that brings the json response from the twitter api. I want to use same code for facebook graph api to get json response from the Facebook but facebook doesn't provide any consumer keys as twitter. I can change this code to get the facebook json response. Can any of you help to modify the code.
public class TwitterResponse {
static String AccessToken = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";
static String AccessSecret = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";
static String ConsumerKey = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";
static String ConsumerSecret = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";
/**

*/
public static void main(String[] args) throws Exception
{
OAuthConsumer consumer = new CommonsHttpOAuthConsumer(ConsumerKey,ConsumerSecret);
String twitterUrl="https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name=heymailme143&count=1&include_rts=true&contributors=true";
consumer.setTokenWithSecret(AccessToken, AccessSecret);
//HttpGet request = new HttpGet("https://api.twitter.com/1.1/friends/list.json");
HttpGet request = new HttpGet(twitter);
consumer.sign(request);
HttpClient client = new DefaultHttpClient();
HttpResponse response = client.execute(request);
int statusCode = response.getStatusLine().getStatusCode();
String m=IOUtils.toString(response.getEntity().getContent());
System.out.println(m);
System.out.println(statusCode + ":" + response.getStatusLine().getReasonPhrase());
}
}
This is a sample code I used to get the twitter response. Could you help me in changing it to get the facebook response using fb graph api?
Have a look at

which also has some examples.

You prepare a URLConnection with proper authentication but then you don't use it when you call url.openStream(). This should work:
...
URLConnection uc = url.openConnection();
uc.setRequestProperty("Authorization", String.format("Basic %s", encoding));
uc.connect();
BufferedReader in = new BufferedReader(new InputStreamReader(uc.getInputStream()));
I'm trying to read html code from a URL Connection. In one case the html file I'm trying to read includes 5 line breaks before the actual doc type declaration. In this case the input reader throws an exception for EOF.
URL pageUrl =
new URL(
"http://www.nytimes.com/2011/03/15/sports/basketball/15nbaround.html"
);
URLConnection getConn = pageUrl.openConnection();
getConn.connect();
DataInputStream dis = new DataInputStream(getConn.getInputStream());
//some read method here
Has anyone ran into a problem like this?
URL pageUrl = new URL("http://www.nytimes.com/2011/03/15/sports/basketball/15nbaround.html");
URLConnection getConn = pageUrl.openConnection();
getConn.connect();
DataInputStream dis = new DataInputStream(getConn.getInputStream());
String urlData = "";
while ((urlData = dis.readUTF()) != null)
System.out.println(urlData);
//exception thrown
java.io.EOFException
at java.io.DataInputStream.readUnsignedShort(DataInputStream.java:323)
at java.io.DataInputStream.readUTF(DataInputStream.java:572)
at java.io.DataInputStream.readUTF(DataInputStream.java:547)
in the case of bufferedreader, it just responds null and doesn't continue
pageUrl = new URL("http://www.nytimes.com/2011/03/15/sports/basketball/15nbaround.html");
URLConnection getConn = pageUrl.openConnection();
getConn.connect();
BufferedReader br = new BufferedReader(new InputStreamReader(getConn.getInputStream()));
String urlData = "";
while(true)
urlData = br.readLine();
System.out.println(urlData);
outputs null
You're using DataInputStream to read data that wasn't encoded using DataOutputStream. Examine the documented behavior for your call to DataInputStream#readUtf(); it first reads two bytes to form a 16-bit integer, indicating the number of bytes that follow comprising the UTF-encoded string. The data you're reading from the HTTP server is not encoded in this format.
Instead, the HTTP server is sending headers encoded in ASCII, per RFC 2616 sections 6.1 and 2.2. You need to read the headers as text, and then determine how the message body (the "entity") is encoded.
This works fine:
package url;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.Reader;
import java.net.URL;
/**
* UrlReader
* #author Michael

public class UrlReader
{
public static void main(String[] args)
{
UrlReader urlReader = new UrlReader();
for (String url : args)
{
try
{
String contents = urlReader.readContents(url);
System.out.printf("url: %s contents: %s\n", url, contents);
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
public String readContents(String address) throws IOException
{
StringBuilder contents = new StringBuilder(2048);
BufferedReader br = null;
try
{
URL url = new URL(address);
br = new BufferedReader(new InputStreamReader(url.openStream()));
String line = "";
while (line != null)
{
line = br.readLine();
contents.append(line);
}
}
finally
{
close(br);
}
return contents.toString();
}
private static void close(Reader br)
{
try
{
if (br != null)
{
br.close();
}
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
This:
public class Main {
public static void main(String[] args)
throws MalformedURLException, IOException
{
URL pageUrl = new URL("http://www.google.com");
URLConnection getConn = pageUrl.openConnection();
getConn.connect();
BufferedReader dis = new BufferedReader(
new InputStreamReader(
getConn.getInputStream()));
String myString;
while ((myString = dis.readLine()) != null)
{
System.out.println(myString);
}
}
}
Works perfectly. The URL you are supplying, however, returns nothing.
