英文:
Basic HTTP Auth in Go
问题
我正在尝试使用下面的代码进行基本的HTTP身份验证，但是它抛出了以下错误：
> 2013/05/21 10:22:58 Get mydomain.example: 不支持的协议方案 ""
> 退出状态 1
func basicAuth() string {
var username string = "foo"
var passwd string = "bar"
client := &http.Client{}
req, err := http.NewRequest("GET", "mydomain.example", nil)
req.SetBasicAuth(username, passwd)
resp, err := client.Do(req)
if err != nil{
log.Fatal(err)
}
bodyText, err := ioutil.ReadAll(resp.Body)
s := string(bodyText)
return s
}
有任何想法我可能做错了什么吗？

Any idea what I may be doing wrong?

潜在的问题是，如果您的网站进行任何重定向... Go语言将在重定向时删除您指定的标头。 （我不得不使用wireshark来查看这个！您可以通过右键单击然后“检查元素”并单击网络选项卡在Chrome中快速找到它）
您需要定义一个重定向函数，将标头添加回去。
func basicAuth(username, password string) string {
auth := username + ":" + password
return base64.StdEncoding.EncodeToString([]byte(auth))
}
func redirectPolicyFunc(req *http.Request, via []*http.Request) error{
req.Header.Add("Authorization","Basic " + basicAuth("username1","password123"))
return nil
}
func main() {
client := &http.Client{
Jar: cookieJar,
CheckRedirect: redirectPolicyFunc,
}
req, err := http.NewRequest("GET", "http://localhost/", nil)
req.Header.Add("Authorization","Basic " + basicAuth("username1","password123"))
resp, err := client.Do(req)
}
英文:
the potential 'gotcha' is if your website does any redirects... Go-lang will drop your specified headers on the redirects. (I had to do wireshark to see this! You can quicky find out in chrome by right-clicking then "inspect element" and click network tab)
you'll want to define a redirect function that adds the header back in.
func basicAuth(username, password string) string {
auth := username + ":" + password
return base64.StdEncoding.EncodeToString([]byte(auth))
}
func redirectPolicyFunc(req *http.Request, via []*http.Request) error{
req.Header.Add("Authorization","Basic " + basicAuth("username1","password123"))
return nil
}
func main() {
client := &http.Client{
Jar: cookieJar,
CheckRedirect: redirectPolicyFunc,
}
req, err := http.NewRequest("GET", "http://localhost/", nil)
req.Header.Add("Authorization","Basic " + basicAuth("username1","password123"))
resp, err := client.Do(req)
}

你需要为NewRequest指定协议，例如"http://"，请参考这里。
req, err := http.NewRequest("GET", "http://mydomain.example", nil)
英文:
You need to specify the protocol for NewRequest, e.g. "http://", see here.
req, err := http.NewRequest("GET", "http://mydomain.example", nil)
