Question

Hello测试出GET和POST方法时我不断获得405方法不允许此资源不允许POST方法。该计划是让用户发布名称和昵称，并使用ajax保存然后显示输入。

该应用已成功部署到Google App Engine。我已经检查了App Engine中的日志，但没有发现错误。有人可以告诉我的python代码是否有问题。我目前正在使用javascript处理一些JSON，是否需要才能使GET，POST方法起作用？感谢您的时间和帮助。

更新

如果我将我的MainPage请求处理程序更改为发布，我仍然会收到405方法错误。

Answer 1

在form中，您的方法为post，但在MainHandler中，您的方法为get，也许这就是您看到405 method not allowed

的原因

适用于Google App Engine的Python：不允许使用405方法
