go - http 查询字符串 : question mark becomes %3

Question

试图附加到现有的查询字符串，但是“？”继续查询字符串被替换为“%3”

 server := "server.com"
 endpoint:= "/buildWithParameters?token=<top_secret>" 

// concat server and build job
    u, err := url.Parse(server)
    u.Path = path.Join(u.Path, endpoint)
    endpoint := u.String()

    // since we are appending to existing querystring, request is needed for parsing
    req, err := http.NewRequest("POST", endpoint, nil)
    if err != nil {
        return fmt.Errorf("Error creating post request: (%v)", err)
    }

    // read existing query string
    q := req.URL.Query()


    q.Add("key", "value")

    req.URL.RawQuery = q.Encode()


    log.Println(req.URL.String())

输出是:

https://server.com/job/jobbyjob/buildWithParameters%3Ftoken=<top_secret>?key=value

Answer 1

那是因为您将查询字符串附加到路径，所以库正确转义了 ?制作一个有效的网址。如果你想要token=<top_secret>要被视为查询的一部分，您需要将其添加到查询中:

endpoint:= "/buildWithParameters" 

// ... 

q.Add("token", "<top_secret>")
