How to Access Request Payload from POST Requests in Java Servlets?

Accessing Request Payload from POST Requests in Java Servlets

When receiving POST requests in Java servlets, accessing the request payload can be a common challenge. This issue arises when the request payload, visible in the "Request Payload" section of Chrome Developer Tools, appears empty within the doPost method despite the POST request being successfully received.

Solution:

To retrieve the request payload in the HttpServletRequest object, you can utilize the following methods effectively:

• getReader(): This method returns a BufferedReader that allows you to read the request body as text.
• getInputStream(): If working with binary data, this method provides a ServletInputStream for reading the raw binary input.

Caution:

As stated in the Java Servlet API documentation, you should use either getReader() or getInputStream(), not both, to avoid potential issues.
