英文:
Golang: AppEngine throws operation not permitted error on Get call
问题
我已经写了一个简单的GAE应用程序，它对外部API进行了一个Get请求，但是我得到了一个非常奇怪的错误：
Get http://kenyan-politicians.popit.mysociety.org/api/v0.1/persons/core_person:1290: dial tcp: stat /etc/resolv.conf: operation not permitted
在我的dev_appserver上，它可以正常工作，所以我想知道可能是什么问题。我没有使用UrlFetch，而是使用了自己的包http://godoc.org/github.com/johnwesonga/go-mzalendo/mzalendo，该包使用了http.NewRequest和http.DefaultClient.Do。
由于AppEngine的限制，我将自己的客户端传递给NewClient调用：
func createHttpClient() *http.Client {
transport := http.Transport{}
client := &http.Client{
Transport: &transport,
}
return client
}
client := createHttpClient()
c := mzalendo.NewClient(client)

I've written a simple GAE app that does a Get call to an external API but I'm getting a very strange error:
Get http://kenyan-politicians.popit.mysociety.org/api/v0.1/persons/core_person:1290: dial tcp: stat /etc/resolv.conf: operation not permitted
On my dev_appserver it works without any problems. So I'm wondering what could be the problem. I'm not using UrlFetch but my own package http://godoc.org/github.com/johnwesonga/go-mzalendo/mzalendo that uses http.NewRequest and http.DefaultClient.Do
Because of AppEngine restrictions I'm passing my own client to the NewClient call:
func createHttpClient() *http.Client {
transport := http.Transport{}
client := &http.Client{
Transport: &transport,
}
return client
}
client := createHttpClient()
c := mzalendo.NewClient(client)

在App Engine上，您必须使用由urlfetch包创建的传输方式。urlfetch的Client函数可以创建一个带有适当传输方式的客户端：
func createHttpClient(r *http.Request) *http.Client {
return urlfetch.Client(appengine.NewContext(r))
}
英文:
On App Engine, you must use a transport created by the urlfetch package. The urlfetch Client function creates a client with an appropriate transport:
func createHttpClient(r *http.Request) *http.Client {
return urlfetch.Client(appengine.NewContext(r))
}
