如何通过Go App Engine Urlfetch包使用Cookie

Question

This code works fine with regular Go code.

cookieJar, err := cookiejar.New(nil)
// error handling
client := &http.Client{Jar: cookieJar}

// authenticate request
authUrl := "https://some_secure_site"
values := make(url.Values)
values.Set("login_email", "email")
values.Set("login_password", "password")
resp, err := client.PostForm(authUrl, values)
// handle error

// process resp

I need to do something similar in App Engine using Go. App Engine uses urlfetch package instead of http package.

How do I use urlfetch package to do this?

Answer 1

urlfetch.Client returns a *http.Client

func Client(context appengine.Context) *http.Client

so simply set the Jar in the created client

client := urlfetch.Client(c)
client.Jar = cookieJar
