javascript - How to intercept ajax requests sent by `axios` in nodejs?

Question

After a general front-end library sends an ajax request, the response object headers will have X-Requested-With:XMLHttpRequest
but## The ajax request sent by #axios does not have this field in the response header

How to intercept the front-end request sent by

axios in nodejs code?

Answer 1

I want to add X-Requested-With header to every request:

axios.defaults.headers.common['X-Requested-With'] = 'XMLHttpRequest';

To intercept the sent ajax, just use spy to replace XMLHttpRequest with the original method.

I can’t figure out why axios doesn’t add this header by default. . .

Answer 2

Add proxy plug-in to intercept it

Answer 3

Are you sure it's an axios problem? Have you tried using another tool? Ajax and axios are just tools for transmitting http requests, so I want to point out that the ajax request sent by the poster's axios is wrong. In addition, I don't know your backend. How to write it? If no acceptable request header is configured when crossing domains, the specified header data will not be obtained. "Access-Control-Allow-Headers": "X-Requested-With"
