Golang:如何使http客户端不遵循重定向?

I would like to make an http call using an http client with these characteristics:

  • don't follow redirects (just get the full response of the first call, which returns a 302 redirect code)
  • being able to receive cookies

Hence, I am looking for a solution with http.Client rather than with trasport.RoundTrip

how can I do that?

    If you use a http.Client, you have the option of using the CheckRedirect field.

    This field takes a custom function which can then handle any redirects if an error is received by the initial request.

    A simple example might be something like this:

    client: &http.Client{
        CheckRedirect: func(req *http.Request, via []*http.Request) error {
            return errors.New("something bad happened") // or maybe the error from the request
        },
    }
    

    You could also return the http.ErrUseLastResponse error which returns the most recent response with its body unclosed.
