HttpUrlConnection authentication not working

Here's the curl command I'm attempting to replicate:

Below is the curl request.

    curl user:password@localhost:8080/foo/bar -d property_one=value_one -d property_two=value_two -d property_three=value_three

And here is the code for httpurlconnection

    URL thisurl = new URL ("http://localhost:8080/foo");
    String encoding = Base64Encoder.base64Encode("user:password");

    HttpURLConnection connection = (HttpURLConnection) thisurl.openConnection();
    connection.setRequestMethod("GET");
    connection.setDoOutput(true);
    connection.addRequestProperty("property_one", "value_one");
    connection.addRequestProperty("property_two", "value_two");
    connection.addRequestProperty("property_three", "property_three");
    connection.setRequestProperty  ("Authorization", "Basic " + encoding);
    InputStream content = (InputStream)connection.getInputStream();

On the connection.getInputStream() line I get a 401 error. Am I doing the authentication wrong?

connection.setRequestMethod("GET");

Here you're setting the method to "GET", which is the same as you used with curl.

connection.setDoOutput(true);

Here you are implicitly setting it to "POST", which isn't the same, so you don't have any reason to expect the same result.

Don't do all this authentication by hand. Use java.net.Authenticator. That's what it's for.

401 error because off user authentication.It may be possible that you are not encoding authentication header properly. use this code it worked for me.you can get detail here here

 URL url = new URL ("http://localhost:8080/foo");
 String encoding = org.apache.catalina.util.Base64.encode(credentials.getBytes("UTF-8"));

URLConnection uc = url.openConnection();
uc.setRequestProperty("Authorization", String.format("Basic %s", encoding));
