Sends Content-Type: json when there is no payload on Nodejs

See original GitHub issue

Summary

axios sends content-type: application/json when sending data as params (query string) and when no data at all for other http methods like DELETE

All api calls were of the form

axios({
    method: "delete"..
}

The fix was to manually set headers["content-type"]="" for such requests.

Context

This happens in node only and works fine in browser.

axios version: v0.18.0
Environment: node v8.10.0, windows 10

If you look at the _header property of ClientRequest you could see that Content-Type: application/json is set.

ClientRequest {

Hi @faztp12 ,

According to this, the default Content-Type is application/x-www-form-urlencoded. Are you using a custom axios instance or just the default one?

axios/lib/defaults.js

Lines 6 to 8 in b4c5d35

var DEFAULT_CONTENT_TYPE = { ‘Content-Type’: ‘application/x-www-form-urlencoded’ }; Cheers 😄 ,

I am using the default one. Searching for the keyword in my entire project brings up only 3 occurrences:

import axios from "axios";
axios({
    ... options ...
})

Axios: 0.18.0 Node: 8.10 All fine in browser

Hope it helps 😃
