英文:
How set cookie with go?
问题
我想让我的 Golang 服务器在 HTTP 响应中发送一个 cookie，以便放置在用户的计算机上。
以下是我的代码：
func userLogin(w http.ResponseWriter, r *http.Request) {
cookie := &http.Cookie{
Name: "my-cookie",
Value: "some value",
}
http.SetCookie(w, cookie)
w.WriteHeader(200)
w.Write([]byte("cookie is set"))
return
}
它在头部被标记了。
但是我看不到要创建的 cookie。
英文:
I would like my golang server to send back a cookie in HTTP raiponce that will be placed on the user's computer.
Here is my code
func userLogin(w http.ResponseWriter, r *http.Request) {
cookie := &http.Cookie{
Name: "my-cookie",
Value: "some value",
}
http.SetCookie(w, cookie)
w.WriteHeader(200)
w.Write([]byte("cookie is set))
return
}
it is marked in the header
but I see no cookie to create

浏览器将cookie路径默认设置为请求路径。
看起来你正在将cookie设置为/<something here>的请求中，但是你期望在/的请求中获取cookie。
通过将cookie路径设置为/来修复。
func userLogin(w http.ResponseWriter, r *http.Request) {
cookie := &http.Cookie{
Name: "my-cookie",
Value: "some value",
Path: "/",
}
http.SetCookie(w, cookie)
w.WriteHeader(200)
w.Write([]byte("cookie is set"))
}
英文:
The browser defaults the cookie path to the request path.
It looks like you are setting the cookie in a request to /<something here>, but are expecting the cookie in a request to /.
Fix by setting the cookie path to /.
func userLogin(w http.ResponseWriter, r *http.Request) {
cookie := &http.Cookie{
Name: "my-cookie",
Value: "some value",
Path: "/",
}
http.SetCookie(w, cookie)
w.WriteHeader(200)
w.Write([]byte("cookie is set))
}
