Http Post request with content type application/x-www-form-urlencoded not working in Spring

Question

Am new to spring currently am trying to do HTTP POST request application/x-www-form-url encoded but when i keep this in my headers then spring not recognizing it an

Answer 1

You have to tell Spring what input content-type is supported by your service. You can do this with the "consumes" Annotation Element that corresponds to your request's "Content-Type" header.

@RequestMapping(value = "/", method = RequestMethod.POST, consumes = {"application/x-www-form-urlencoded"})

It would be helpful if you posted your code.

Answer 2

The easiest thing to do is to set the content type of your ajax request to "application/json; charset=utf-8" and then let your API method consume JSON. Like this:

var basicInfo = JSON.stringify({
    firstName: playerProfile.firstName(),
    lastName: playerProfile.lastName(),
    gender: playerProfile.gender(),
    address: playerProfile.address(),
    country: playerProfile.country(),
    bio: playerProfile.bio()
});

$.ajax({
    url: "http://localhost:8080/social/profile/update",
    type: 'POST',
    dataType: 'json',
    contentType: "application/json; charset=utf-8",
    data: basicInfo,
    success: function(data) {
        // ...
    }
});


@RequestMapping(
    value = "/profile/update",
    method = RequestMethod.POST,
    produces = MediaType.APPLICATION_JSON_VALUE,
    consumes = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<ResponseModel> UpdateUserProfile(
    @RequestBody User usersNewDetails,
    HttpServletRequest request,
    HttpServletResponse response
) {
    // ...
}

I guess the problem is that Spring Boot has issues submitting form data which is not JSON via ajax request.

Note: the default content type for ajax is "application/x-www-form-urlencoded".

Answer 3

The problem is that when we use application/x-www-form-urlencoded, Spring doesn't understand it as a RequestBody. So, if we want to use this we must remove the @RequestBody annotation.

Then try the following:

@RequestMapping(value = "/patientdetails", method = RequestMethod.POST,consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
public @ResponseBody List<PatientProfileDto> getPatientDetails(
        PatientProfileDto name) {


    List<PatientProfileDto> list = new ArrayList<PatientProfileDto>();
    list = service.getPatient(name);
    return list;
}

Note that removed the annotation @RequestBody

Answer 4

Remove @ResponseBody annotation from your use parameters in method. Like this;

   @Autowired
    ProjectService projectService;

    @RequestMapping(path = "/add", method = RequestMethod.POST)
    public ResponseEntity<Project> createNewProject(Project newProject){
        Project project = projectService.save(newProject);

        return new ResponseEntity<Project>(project,HttpStatus.CREATED);
    }

Answer 5

The solution can be found here https://github.com/spring-projects/spring-framework/issues/22734

you can create two separate post request mappings. For example.

@PostMapping(path = "/test", consumes = "application/json")
public String test(@RequestBody User user) {
  return user.toString();
}

@PostMapping(path = "/test", consumes = "application/x-www-form-urlencoded")
public String test(User user) {
  return user.toString();
}

Answer 6

you should replace @RequestBody with @RequestParam, and do not accept parameters with a java entity.

Then you controller is probably like this:

@RequestMapping(value = "/patientdetails", method = RequestMethod.POST, 
consumes = {MediaType.APPLICATION_FORM_URLENCODED_VALUE})
public @ResponseBody List<PatientProfileDto> getPatientDetails(
    @RequestParam Map<String, String> name) {
   List<PatientProfileDto> list = new ArrayList<PatientProfileDto>();
   ...
   PatientProfileDto patientProfileDto = mapToPatientProfileDto(mame);
   ...
   list = service.getPatient(patientProfileDto);
   return list;
}
