How to upload a file and JSON data in Postman?


Question

I am using Spring MVC and this is my method:

/**
* Upload single file using Spring Controller.
*/
@RequestMapping(value = "/uploadFile", method = RequestMethod.POST)
public @ResponseBody ResponseEntity<GenericResponseVO<? extends IServiceVO>> uploadFileHandler(
            @RequestParam("name") String name,
            @RequestParam("file") MultipartFile file,
            HttpServletRequest request,
            HttpServletResponse response) {

    if (!file.isEmpty()) {
        try {
            byte[] bytes = file.getBytes();

            // Creating the directory to store file
            String rootPath = System.getProperty("catalina.home");
            File dir = new File(rootPath + File.separator + "tmpFiles");
            if (!dir.exists()) {
                dir.mkdirs();
            }

            // Create the file on server
            File serverFile = new File(dir.getAbsolutePath() + File.separator + name);
            BufferedOutputStream stream = new BufferedOutputStream(new FileOutputStream(serverFile));
            stream.write(bytes);
            stream.close();

            System.out.println("Server File Location=" + serverFile.getAbsolutePath());

            return null;
        } catch (Exception e) {
            return null;
        }
    }
}


I need to pass the session id in postman and also the file. How can I do that?

Accepted Answer

In postman, set method type to POST.

Then select Body -> form-data -> Enter your parameter name (file according to your code)

and on right side next to value column, there will be dropdown "text, file", select File. choose your image file and post it.

For rest of "text" based parameters, you can post it like normally you do with postman. Just enter parameter name and select "text" from that right side dropdown menu and enter any value for it, hit send button. Your controller method should get called.

Maybe you could do it this way:

postman_file_upload_with_json

Like this :

enter image description here

Body -> form-data -> select file

You must write "file" instead of "name"

Also you can send JSON data from Body -> raw field. (Just paste JSON string)

  1. Don't give any headers.
  2. Put your json data inside a .json file.
  3. Select your both files one is your .txt file and other is .json file for your request param keys.

If you need like Upload file in multipart using form data and send json data(Dto object) in same POST Request

Get yor JSON object as String in Controller and make it Deserialize by adding this line

ContactDto contactDto  = new ObjectMapper().readValue(yourJSONString, ContactDto.class);

Postman multipart form-data content-type

Select [Content Type] from [SHOW COLUMNS] then set content-type of "application/json" to the parameter of json text.
