GAE SDK 1.7.4和InvalidCertificateException

Question

最近,我将GAE SDK升级到了ver.1.7.4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推移而消失,但我没有.我应该考虑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,如果这必须以某种方式.

我找到的快速解决方法:google_appengine/lib/cacerts/cacerts.txt从已安装的SDK中删除该文件.

从GoogleAppEngineLauncher开始:

GoogleAppEngineLauncher /内容/资源/ GoogleAppEngineDefault.bundle /内容S /资源/ google_appengine/lib中/ cacerts中/ cacerts.txt

编辑#

截至谷歌应用引擎SDK 1.8.1此文件已重命名为urlfetch_cacerts.txt.仍然在同一目录中删除它仍然可以解决问题.
