Google App Engine Localhost后端错误 [英] Google App Engine Localhost Backend Error

问题描述

我正在尝试在本地主机上运行测试GAE后端，但出现以下错误:

I am trying to run a test GAE backend on my localhost and I am getting the following error:

com.google.appengine.tools.development.InstanceHelper sendStartRequest
WARNING: Start request to /_ah/start on server 0.export failed (HTTP status code=405). Retrying...

我的代码如下:

backends.xml

backends.xml

<backends>
    <backend name="example">

            <instances>1</instances>
            <public>false</public>
            <dynamic>true</dynamic>
        </options>
    </backend>
</backends>

谢谢您的帮助.

推荐答案

您已连接 com.test.backend.BackendTest 来处理启动请求.它需要处理GET请求并以200(实际上是200-299可以)或400进行响应.

You've hooked up com.test.backend.BackendTest to handle start requests. It needs to handle a GET request and respond with 200 (actually 200-299 will do) or a 400.

此处的详细信息: https://developers.google.com/appengine/docs/java/backends/#Java_Startup

405响应听起来像您没有提供覆盖 get()的处理程序.

A 405 response sounds like you didn't supply a handler that overrides get().
