内容类型为application / x-www-form-urlencoded的Http Put请求在Spring中不起作用

Question

I have a spring-boot application that the only thing it does is receive http requests.

This is my spring cotroller:

@RestController
public class WebController {

    @Autowired
    private CallRecording callRecording;

    @PutMapping(path = "/cdrpostbox/callrecording/{hostedAccountId}/{mp3FileName}", consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
    public ResponseEntity<Object> callRecording(@PathVariable("hostedAccountId") String hostedAccountId, @PathVariable("mp3FileName") String mp3FileName, MultipartFile file) {
        return ResponseEntity.status(callRecording.service(hostedAccountId, mp3FileName, file)).body(null);
    }

}

I'm using Postman to send the request. The request that my spring application receives can't be changed, because the code is not maintained by my team.

request headers

request body

I found quite a few questions in here about the similar problems, but not quite the same problem that I have to solve. I tried adding and removing @RequestBody , replacing @RequestBody with @RequestParam , I tried the MultiValueMap , but it keeps returning the same error.

java.lang.IllegalArgumentException: URLDecoder: Illegal hex characters in escape (%) pattern - For input string: "x"

I can't even debug the code because it fails before it reaches the controller.

What am I missing?

Answer 1

The content-type in the header is urlencoded, but you send binary data.

--- edit

If you want to get the file as a MultipartFile, then send the file as a form-data from postman, set the name of the data to file and add @RequestParam to the file argument in your method.

Answer 2

After a bit more investigation, I found the solution.

@RestController
@EnableWebMvc
public class WebController {

    @Autowired
    private CallRecording callRecording;

    @PutMapping(path = "/cdrpostbox/callrecording/{hostedAccountId}/{mp3FileName:.+}")
    public ResponseEntity<Object> callRecording(@PathVariable("hostedAccountId") String hostedAccountId, @PathVariable("mp3FileName") String mp3FileName, @RequestBody byte[] requestBody) {
        return ResponseEntity.status(callRecording.service(hostedAccountId, mp3FileName, requestBody)).body(null);
    }

It was missing the @EnableWebMvc . I also changed the mapping {mp3FileName:.+} because it was truncating the end of the request, you can check the SO question here .

Thanks @Selindek for the help
