Question

我正在尝试编写一个程序，它将登录ahrefs.com并解析一些数据。我首先向ahrefs.com发送GET请求以获取cookie和html来解析所需的令牌：

    client := &http.Client{}
    jar := &myjar{}
    jar.jar = make(map[string] []*http.Cookie)
    client.Jar = jar
    resp, _ := client.Get("https://ahrefs.com")

    root, _ := html.Parse(resp.Body)
    element, _ := getElementByName("_token", root)
    token := ""
    for _, a := range element.Attr {
        if a.Key == "value" {
            token = a.Val
        }
    }

然后我使用PostForm向ahrefs.com/user/login/发送POST请求。我用正确的数据填充字段（通过浏览器测试）。当我在浏览器中提交表单时，它的字段return_to具有站点主页的值，应该重定向到ahrefs.com/dashboard/metrics/（我要解析数据的页面）。但我的节目的行为是不同的。在PostForm 301后，我获得了resp, _ = client.PostForm( "https://ahrefs.com/user/login/", url.Values{ "email": {"djviman@gmail.com"}, "password": {"Aau4bqRxfc4ZEvu"}, "_token": {token}, "return_to": {"https://ahrefs.com/"}, }) log.Println(resp.Status) resp.Body.Close()状态代码：

ahrefs.com/dashboard/metrics/

然后我向resp, _ = client.Get("https://ahrefs.com/") log.Println(resp.Status) resp.Body.Close()发送GET请求，但它将我重定向到主页，就像我没有登录一样：

问题是：我做错了什么？并且热门成功登录此站点？

PostForm之后的301状态代码
