Axios: Ignoring Proxy Config with React Native

 Summary

When trying to fetch to server with proxy, it just ignores proxy setting and fetch to server.
This problem already mentioned in this issue (https://github.com/mzabriskie/axios/issues/672)
But closed for some reason. and still occurred now.
I am using latest versions of react-native, and axios.
Here is my code below.

let config = {
      proxy: {
        host: '127.0.0.1',
        port: 8118
      }
    }
    axios.get('https://api.ipify.org/', config)
    .then(function (response) {
      console.log("-----------");
      console.log(response.data);
      console.log("-----------");
    })

Output: _Original IP, not proxied one_

 Context

• axios version: v0.16.2
• Environment: node v.8.3.0, and react-native-cli 2.0.1
