can i change the headers['content-type'] before a get request?

our back api limit the request content-type must be an fixed value, even it’s a get request.

but i see the source code will remove the content-type when request data is undefined,

so i set an empty data before request, like

if (!config.data) { config.data = "" } then set the content-type . this will work well on IOS device; but crashed on android device,

it will throw an error,

GET must not have a request body

is there any solution to fix this problem? thanks~

Hi @HengCC,

I believe what you’re looking for is something like this:

axios.get('some_url', {headers: {Content-Type: 'application/json'}})
  .then((res) => {
    //do something
  })
  .catch((err) => {
    //do something
  });

Cheers 😄,

@delirius325 It does not gets sent as the header gets deleted here https://github.com/axios/axios/blob/98080381fa78dcffa91a15e6d25617583d13e533/dist/axios.js#L802

and if you would debug at this line before and after you would see this.
