我正在尝试运行托管在以下位置的示例应用程序:https://github.com/googlesamples/cloud-polymer-go ，但是在代理后面运行它时，出现以下错误:

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工作。

我在 Ubuntu 14.04 下。

最佳答案

编辑 看起来 SDK 在使用 URLFetch 代理方面存在缺陷。

尝试设置这些环境变量的大写版本，HTTP_PROXY 和 HTTPS_PROXY。 gcloud launcher需要它们，所以我假设 goapp 也是如此。

Using an HTTP proxy

If you are running gcloud preview app behind an HTTP proxy, you must tell gcloud preview app the name of the proxy. To set an HTTP proxy for gcloud preview app, set the http_proxy and https_proxy environment variables. Note that you must specify the full path for the app.yaml file.

Using Windows (in Command Prompt):

$ set HTTP_PROXY=http://cache.mycompany.com:3128
$ set HTTPS_PROXY=http://cache.mycompany.com:3128
$ gcloud preview app deploy DIRECTORY/app.yaml

Using the command line in Mac OS X (in Terminal) or Linux:

$ export HTTP_PROXY="http://cache.mycompany.com:3128"
$ export HTTPS_PROXY="http://cache.mycompany.com:3128"
$ gcloud preview app deploy DIRECTORY/app.yaml
