Esp8266 hTTP-Post 302 Rfid 传感器问题

Question

我最近一直在做项目，我很难解决这个问题。在我点击 esp8266 中的 rfid 卡后，它发送数据正常，但之后串行监视器显示代码 302 问题，现在我无法再次点击我的卡，它完全停止程序。我一直在工作的逻辑是，如果用户或卡点击 rfid 传感器，它将放入 4 列。在 A 列中，它将生成日期和 B 列时间或超时 我希望如果用户点击一次，它将像这样输入“TIME IN (8:30 AM)”，如果是下午“TIME IN (8:30 PM) ）”它会像这样，如果用户再次点击我想发送另一个数据以使其在另一行中成为超时逻辑。

这只是我点击卡一次并在串行监视器中收到代码302后的结果 串行监视器中的代码 302

Answer 1

HTTP Code 302 不报告错误，它是服务器重定向到新位置。
