前后端分离下 后端请求授权 回调地址填写前端路由 监听到url里面存在code参数。则请求授权回调接口。

授权接口

func (*WeiBo)WeiBoCallBack (c *gin.Context)  {
code := c.Query("code")

    if len(code) ==0 {
        c.JSON(http.StatusForbidden,map[string]interface{}{"msg": "参数不正确～","code":code,})}//微博授权
    access_token := oauth.GetAccessToken(&code)
    UserInfo := oauth.GetUserInfo(&access_token)
    fmt.Println(UserInfo)//注册逻辑以及生产token
}

微博授权服务类
