「新手上路」Go 微博授權登入

前後端分離下 後端請求授權 回撥地址填寫前端路由 監聽到url裡面存在code引數。則請求授權回撥介面。

授權介面

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

    if len(code) ==0 {
        c.JSON(http.StatusForbidden,map[string]interface{}{
            "msg": "引數不正確～",
            "code":code,
        })
    }
    //微博授權
    access_token := oauth.GetAccessToken(&code)
    UserInfo := oauth.GetUserInfo(&access_token)
    fmt.Println(UserInfo)
    //註冊邏輯以及生產token
}
