登录到Twitter总是使用回调失败方法

Question

没有显示错误，但是当单击按钮时，始终将失败方法。Internet处于活动状态，键是有效的。我使用调试器查看以下结果： -

Answer 1

我在设备上未安装Twitter应用程序时遇到了相同的错误。

桌面应用程序仅支持OAUTH_CALLBACK值 'oob' /oauth/request_token

但是，当设备上安装了Twitter应用程序时，Twitter登录工作正常工作。

如果未在设备上安装Twitter应用程序，请获取Twitter登录工作，请对您的应用进行以下更改：

https://apps.twitter.com/app/13917465/permissions

转到应用程序中的"权限"选项卡，更改"读取，写入和访问直接消息"，并在"其他权限"中启用"从用户请求电子邮件地址"。

最后，通过单击"更新设置"来保存更改。
