devServer proxy does not work as advertised

[Rayraegah]

Version

3.0.0-beta.5

Reproduction link

https://github.com/Rayraegah/cli-error-axios

Steps to reproduce

• Configure a proxy under devServer in vue.config.js (e.g. '/gists' : 'https://api.github.com')
• Use Axios to send a POST (.e.g. axios.post('/gists/...'))
• Use Axios to send a GET (.e.g. axios.get('/gists/...'))
• Repeat using fetch instead of Axios (same errors)

What is expected?

The axios post request should be proxied to https://api.github.com like GET requests do. Sometimes the GET requests are not proxied.

What is actually happening?

The axios request goes to https://localhost:8080/gists/... instead of https://api.github.com/gists

The issue is the same as the one in create-react-app that was resolved recently.
refer: facebook/create-react-app#3726 and facebook/create-react-app#3311

On my main repo, GET requests were successful, only POST failed. But in the test repo - both GET and POST end in errors.

@yyx990803 Why close this issue? You haven't resolved this problem yet. I think a bug tag is better than closing this issue.

Just to clarify this was partially resolved in Beta-6 release. PUT and POST requests made via Axios are working but with fetch it is not.
