在 Twitter 上，您只能发布 140 个字符的帖子。这包括您在推特上发布的句柄：@handle. 当试图在更大的群体中发布推文时，这会产生问题。为了尝试为我的篮球队创建一个解决方法，我正在尝试创建一个 twitter 机器人，当发推文时，它会从推文中获取文本，然后在团队中每个人的句柄上发送一系列推文。
我从本教程中的代码开始。然后我编辑了 Wolfram Alpha 的东西并想出了这个代码开始：（密钥和秘密不是真的 xxxxx）

（我的理解是）这段代码应该只是导致 twitter 机器人在发推文时发布一条推文，上面写着“看起来它有效”。
但是我似乎有一个我不明白的授权问题。大多数晚上我都会收到这封电子邮件：
