Why are Headers Not Being Recognized in My HttpURLConnection Requests?

Adding Headers to HttpURLConnection Requests

When attempting to add headers to your HttpURLConnection requests, you may encounter situations where the server fails to acknowledge the header information. If setting the request property using setRequestProperty() doesn't resolve the issue, consider the following solution:

Solution:

To ensure that headers are set correctly, try the following steps:

1. Create a new instance of HttpURLConnection:

   URL myURL = new URL(serviceURL);
   HttpURLConnection myURLConnection = (HttpURLConnection)myURL.openConnection();

2. Prepare the header value:

   String userCredentials = "username:password";
   String basicAuth = "Basic " + new String(Base64.getEncoder().encode(userCredentials.getBytes()));

3. Set the "Authorization" header:

   myURLConnection.setRequestProperty ("Authorization", basicAuth);

4. Configure the connection:

   myURLConnection.setRequestMethod("POST"); // Assuming a POST request
   myURLConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
   myURLConnection.setRequestProperty("Content-Length", "" + postData.getBytes().length);
   myURLConnection.setRequestProperty("Content-Language", "en-US");
   myURLConnection.setUseCaches(false);
   myURLConnection.setDoInput(true);
   myURLConnection.setDoOutput(true);

This modified approach should ensure that the "Authorization" header is correctly added to the request and should be received by the server.
