GAE SDK 1.7.4和InvalidCertificateException [英] GAE SDK 1.7.4 and InvalidCertificateException

问题描述

最近，我将GAE SDK升级到了当我尝试运行开发服务器时，它开始抛出InvalidCertificateException。我搜索了这个错误，有些人说它随着时间的流逝而消失，但我没有。我应该研究什么来解决这个问题？我正在使用python框架Django为我的应用程序，如果这不得不重要。

Recently, I upgraded my GAE SDK to ver. 1.7.4 and it started to throw 'InvalidCertificateException' when I try to run development server. I searched about this error and some people said it goes away with time, but mine didn't. What should I look into to fix this problem? I am using python framework Django for my app if that has to matter somehow.

推荐答案

我发现的快速解决方法：删除fi从您安装的SDK中获取 google_appengine / lib / cacerts / cacerts.txt

Quick workaround that I found: delete the file google_appengine/lib/cacerts/cacerts.txt from your installed SDK.

从GoogleAppEngineLauncher开始： p>

Starting from the GoogleAppEngineLauncher:

GoogleAppEngineLauncher / Contents / Resources / GoogleAppEngineDefault.bundle / Content s / Resources / google_appengine / lib / cacerts / cacerts.txt

GoogleAppEngineLauncher/Contents/Resources/GoogleAppEngineDefault.bundle/Content‌​s/Resources/google_appengine/lib/cacerts/cacerts.txt

编辑＃

Google应用引擎SDK 1.8。 1这个文件被重命名为
urlfetch_cacerts.txt。仍然在同一个目录并删除它
仍然解决了这个问题。

as of google app engine SDK 1.8.1 this file as been renamed to urlfetch_cacerts.txt. Still in the same directory and removing it still fixes the problem.
