Answer 1

When I use postman to send a file which is 5.6M to an external network, I faced the same issue. The same action is succeeded on my own computer and local testing environment.

After checking all the server configs and HTTP headers, I found that the reason is Postman may have some trouble simulating requests to external HTTP requests. Finally, I did the sendfile request on the chrome HTML page successfully. Just as a reference :)

I was having the same problem while making a POST request from Postman and later I could solve the problem by setting a custom Content-Type with a boundary value set along with it like this.

I thought people can run into similar problem and hence, I'm sharing my solution.

Unchecked the content type in Postman and postman automatically detect the content type based on your input in the run time.

Answer 4

I met this problem because I use request.js which writen base on axios
And I already set a defaults.headers in request.js

import axios from 'axios'
const request = axios.create({
  baseURL: '', 
  timeout: 15000 
})
service.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded'

here is how I solve this
instead of

request.post('/manage/product/upload.do',
      param,config
    )

I use axios directly send request,and didn't add config

axios.post('/manage/product/upload.do',
      param
    )

hope this can solve your problem
