Question 219918 in Javascript Question posted in
A very good W3school tutorial can be found here.

Javascript – Method 'GET' is not supported

When I make HTTP POST request, I got this message on my screen. How can I solve this problem? I don’t use any GET annotation or request.

HTPP REQUEST : http://localhost:9000/user/register?username=a&password=1

Console Error

Failed to load resource: the server responded with a status of 405 (Method Not Allowed)

JavaScript

<script>
document.getElementById("signupbtn").addEventListener("click",function(){
    const username = document.getElementById("username").value;
    const password = document.getElementById("password").value;
    const xhr = new XMLHttpRequest(); 
    xhr.open("POST","http://localhost:9000/user/register?username="+username+"&password="+password);
    xhr.send();
  })

</script>

Controller

@PostMapping("/register")
ResponseEntity<String> addUser(@RequestParam("username") String username,@RequestParam("password") String password) {
    userService.addUser(username, password);
    return ResponseEntity.ok("User added succesfully");
}

Service

public void addUser(String username,String password){
    userRepository.save(new User(username,password));
       
}

    The problem is when i send to request. This is a GET request not POST . I changed the PostMapping To GetMapping problem is solved. I think there is missunderstanding about POST and GET mapping

    there is nothing wrong with your code , it should work unless you do have restriction in your app security config like (allowedMethods )
