我正在为 google oauth2 https://github.com/golang/oauth2使用以下库

我正在使用示例中给出的代码（网址：http : //play.golang.org/p/qXyuaVEhyS，https ://godoc.org/golang.org/x/oauth2/google ）

我能够获取身份验证代码和令牌，但无法发出获取请求以获取用户信息

我的代码：

conf := &oauth2.Config{
        ClientID:     "my client id",
        ClientSecret: "secred id",
        RedirectURL:  "http://localhost:3000/googlelogin",
        Scopes: []string{
            "https://www.googleapis.com/auth/userinfo.profile",
        },
        Endpoint: google.Endpoint,
    }

m.Get("/googleloginrequest", func(r render.Render, request *http.Request) {

    url := conf.AuthCodeURL("state")
    fmt.Printf("Visit the URL for the auth dialog: %v", url)

    r.Redirect(url)

})

m.Get("/googlelogin", func(r render.Render, request *http.Request) {

        authcode := request.FormValue("code")

        tok, err := conf.Exchange(oauth2.NoContext, authcode)
        if err != nil {
            log.Fatal(err)
        }

        client := conf.Client(oauth2.NoContext, tok)

        resp, err :=client.Get("https://www.googleapis.com/userinfo/v2/me")

        r.JSON(200, map[string]interface{}{"status":resp})
    })

我在这里得到的回复非常大，没有任何用户信息

回复 ：

请帮助或建议我在上述情况下工作的其他工作库/代码

这个库为我工作“golang.org/x/oauth2/google”

初始化

googleconf = &oauth2.Config{
        ClientID:     "your-client-id",
        ClientSecret: "youe-secred",
        RedirectURL:  "http://localhost:300/googlelogin",
        Scopes: []string{
            "https://www.googleapis.com/auth/userinfo.profile",
            "https://www.googleapis.com/auth/userinfo.email",
        },
        Endpoint: google.Endpoint,
    }

根据请求重定向用户：

url := googleconf.AuthCodeURL("state")
response.Redirect(url)

从谷歌获取数据：

    authcode := request.FormValue("code")

    tok, err := googleconf.Exchange(oauth2.NoContext, authcode)
    if err != nil {
        fmt.Println("err is", err)
    }

    fmt.Println("token is ", tok)
    response, err := http.Get("https://www.googleapis.com/oauth2/v2/userinfo?access_token=" + tok.AccessToken)

    defer response.Body.Close()
    contents, err := ioutil.ReadAll(response.Body)
