Unsupported Media Type in postman - spring

Question

I am implementing spring security with oauth2 and jwt.
the below is my login function
function doLogin(loginData) {
$.ajax({
url : back+"/auth/secret",
type : "POST",
data : JSON.stringify(loginData),
contentType : "application/json; charset=utf-8",
dataType : "json",
async : false,
success : function(data, textStatus, jqXHR) {
setJwtToken(data.token);
},
error : function(jqXHR, textStatus, errorThrown) {
alert("an unexpected error occured: " + errorThrown);
window.location.href= back+'/login_page.html';
}
});
}
And down I have the Controller
#RequestMapping(value = "auth/secret", method = RequestMethod.POST)
public ResponseEntity<?> createAuthenticationToken(#RequestBody JwtAuthenticationRequest authenticationRequest, Device device) throws AuthenticationException {
System.out.println();
logger.info("authentication request : " + authenticationRequest.getUsername() + " " + authenticationRequest.getPassword());
// Perform the security
System.out.println( authenticationRequest.getUsername()+"is the username and "+authenticationRequest.getPassword());
final Authentication authentication = authenticationManager.authenticate(
new UsernamePasswordAuthenticationToken(
authenticationRequest.getUsername(),
authenticationRequest.getPassword()
)
);
SecurityContextHolder.getContext().setAuthentication(authentication);
logger.info("authentication passed");
// Reload password post-security so we can generate token
final UserDetails userDetails = userDetailsService.loadUserByUsername(authenticationRequest.getUsername());
final String token = jwtTokenUtil.generateToken(userDetails, device);
logger.info("token " + token);
// Return the token
return ResponseEntity.ok(new JwtAuthenticationResponse(token));
}
But when I try the post request with the postman it shows me
{
"timestamp": 1488973010828,
"status": 415,
"error": "Unsupported Media Type",
"exception": "org.springframework.web.HttpMediaTypeNotSupportedException",
"message": "Content type 'multipart/form-data;boundary=----WebKitFormBoundaryY4KgeeQ9ONtKpvkQ;charset=UTF-8' not supported",
"path": "/TaxiVis/auth/secret"
}
But when I do cosole.log(data) in the ajax call it prints the token?I could not figure out what is wrong.Any help is appreciated.

Answer 1

You need to set the content-type in postman as JSON (application/json).
Go to the body inside your POST request, there you will find the raw option.
Right next to it, there will be a drop down, select JSON (application.json).

Answer 2

Http 415 Media Unsupported is responded back only when the content type header you are providing is not supported by the application.
With POSTMAN, the Content-type header you are sending is Content type 'multipart/form-data not application/json. While in the ajax code you are setting it correctly to application/json. Pass the correct Content-type header in POSTMAN and it will work.

Answer 3

I also got this error .I was using Text inside body after changing to XML(text/xml) , got result as expected.
If your request is XML Request use XML(text/xml).
If your request is JSON Request use JSON(application/json)

Answer 4

If you are still failing with Unsupported Media Type in postman
when calling a SOAP endpoint you could try:
Content-Type: application/soap+xml

Answer 5

i was also having a similar issue. in my case i made two changes
Click on headers tag and add a key 'Content-Type' with Value 'application/json'
Second step is to click on Body tab and select 'raw' radio button and select type as 'JSON' from dropdown as shown below

Answer 6

I had this problem. I had authentication on the authentication tab set up to pass credentials in body.
This error occurred for me when I had the Body set to None.
So I needed an empty body in postman, set to raw JSON to allow this to work even though my main request was parameters in the querystring.
{
}

Answer 7

When this was happening with me in XML;
I just changed "application/XML" to be "text/XML",
which solved my problem.
