Problems using Go App Engine behind a proxy

问题

我正在尝试运行托管在https://github.com/googlesamples/cloud-polymer-go的示例应用程序，但在代理后运行时，我遇到以下错误：

变量设置如下：

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

已正确设置。

我可以使用直接的互联网连接。

我使用的是Ubuntu 14.04。

The variables:

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

Are correctly set.

I works with a direct Internet connection.

I'm under Ubuntu 14.04.

编辑 看起来在使用URLFetch时SDK存在一个缺陷，涉及使用代理。

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启动器要求以这种方式设置，所以我认为goapp也是如此。

使用HTTP代理

如果您在HTTP代理后面运行gcloud preview app，您必须告诉gcloud preview app代理的名称。要为gcloud preview app设置HTTP代理，请设置http_proxy和https_proxy环境变量。请注意，您必须为app.yaml文件指定完整路径。

在Windows中（在命令提示符中）：

$ 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（在终端）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
英文:

EDIT Looks like there is a defect in the SDK around using a proxy with URLFetch.

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

Try setting the uppercase versions of those environment variables, HTTP_PROXY and HTTPS_PROXY. The gcloud launcher requires them that way so I assume goapp does as well.

>
