Passing custom props via axios config

Describe the bug We use some custom parameters via axios configuration. They are used in the response interceptor. Sometimes there may be a lot of information there, so the option to pass it through the headers or params is not suitable for us because of the length limit

To Reproduce

• Open: https://jsfiddle.net/w2rmhy4c/1/
• Attach axios 0.18 (uncomment line with axios@0.18.0)
• Run fiddle (console show true)
• Attach axios 0.19 (uncomment line with axios@0.19.0)
• Run fiddle (console show undefined)

Expected behavior Custom config parameter passed. Or the ability to use another config option to pass custom data.

Environment:

• Axios Version 0.18/0.19

Additional context/Screenshots First messages with axios 0.18, second with 0.19

I need this too. I had this working in 0.18 but it stopped working in 0.19

I used something like this:

    await axios({
      url: '/search',
      method: 'GET',
      params,
      myCustomParameter: true
    } as ICustomAxiosRequestConfig)

but it no longer shows up in the interceptor config:

axios.interceptors.request.use(function (config) {
})

Edit: just confirmed this works in 0.18.1 so I’m reverting back for now
