How to upload a file and JSON data in Postman?
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.

The Missing Visual Guide
You must first find the nearly-invisible pale-grey-on-white dropdown for File
which is the magic key that unlocks the Choose Files
button.
After you choose POST
, then choose Body->form-data
, then find the File dropdown, and then choose 'File', only then will the 'Choose Files' button magically appear:
Read more... Read less...
Like this :
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)
- Don't give any headers.
- Put your json data inside a .json file.
- 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);
Select [Content Type] from [SHOW COLUMNS] then set content-type of "application/json" to the parameter of json text.
