Question

我正在尝试运行托管在https://github.com/googlesamples/cloud-polymer-go的示例应用程序，但是当在代理后面运行它时，我会收到以下错误：

变量：

$ echo $http_proxy 
http://asusis-isa2.personal.com.py:8080/
$ echo $https_proxy 
http://asusis-isa2.personal.com.py:8080/

设置正确。

我使用直接互联网连接。

我在Ubuntu 14.04下。

编辑看起来SDK中存在使用带URLFetch的代理的缺陷。

https://code.google.com/p/googleappengine/issues/detail?id=544

尝试设置这些环境变量的大写版本HTTP_PROXY和HTTPS_PROXY。 gcloud launcher要求他们这样，所以我假设goapp也这样做。

使用HTTP代理

如果您在HTTP代理后面运行gcloud预览应用程序，则必须   告诉gcloud预览应用程序代理的名称。设置HTTP代理   对于gcloud预览应用程序，请设置http_proxy和https_proxy环境   变量。请注意，您必须指定app.yaml的完整路径   文件。

使用Windows（在命令提示符下）：
$ set HTTP_PROXY=http://cache.mycompany.com:3128
$ set HTTPS_PROXY=http://cache.mycompany.com:3128
$ gcloud preview app deploy DIRECTORY/app.yaml
在Mac OS X（终端中）或Linux中使用命令行：
$ export HTTP_PROXY="http://cache.mycompany.com:3128"
$ export HTTPS_PROXY="http://cache.mycompany.com:3128"
$ gcloud preview app deploy DIRECTORY/app.yaml

在代理后面使用Go App Engine的问题
