Postman form-data works, but the raw equivalent doesn't

Question

I have an API that I'm testing with and if I submit my data through "form-data" with the following values it works:

key: response[comment]
value: This is a test

But if I do some custom JSON in the "raw" tab with the following structure, it doesn't work:

{ "response[comment]": "This is a test" }

It's driving me nuts to be honest as the server doesn't give me any details on what's wrong. I have the feeling it's the encoding of the object that goes wrong, but I'm using Angular and I get the same 400 error, while I'm fairly sure it should just work with a JS object as the data on a .post.

Any help would be appreciated!

Solution 1

Ensure your Content-Type header!

If your raw data is JSON: Content-Type: application/json

I experienced a similar issue to yours: my request was working using the form-data, but not as raw... and after debugging the request server side, I realised my request Content-Type was "text/plain;charset=UTF-8".. even if JSON was selected in the side dropdown...

Hope it saves time to the next one ;)

Solution 2

Okay I found it.

Apparently the "comment[response]" is actually:

{"comment":{"response": "something"}}

in JSON.

Learned something :)

Solution 3

Select raw option with JSON(application/json).
