Server to server OAuth2
问题
我正在尝试实现一个用于访问Google Analytics数据的Golang应用程序，但所有的示例都使用在一小时内失效的令牌。
在API访问中，我找到了一个"证书访问"的方式，它被设计用于从服务器访问，但我找不到在Golang中实现它的示例。是否有相关的阅读材料，或者你能为我指点迷津吗？
我正在使用这个库：
code.google.com/p/google-api-go-client/
在这里阅读了一些帖子，我找到了这个链接：https://stackoverflow.com/questions/9863509/service-applications-and-google-analytics-api-v3-server-to-server-oauth2-authen
但似乎它不能直接工作。难道没有其他方法可以在不进行额外处理的情况下实现吗？

I'm trying to implement a Golang application for accessing Google Analytics data. but all the examples uses tokens that dies in one hour.
In the api access i found a "Certificate access" that are designed to be used to access from servers, but i failed to find examples of its implementation in Golang. there is some reading or may you can enlighten my path for this?
I'm using this library.
code.google.com/p/google-api-go-client/
reading some post here I found this https://stackoverflow.com/questions/9863509/service-applications-and-google-analytics-api-v3-server-to-server-oauth2-authen
but it seems that it will not work directly. is really no way of doing this w/o hacking it around?

你是否已经查看了OAuth2包？我曾经使用它进行用户授权调用，并对其进行了一些修改，使其能够处理多个授权来源。我还没有测试过它在纯服务器之间的通信中的应用，但你应该能够修改传输代码以满足需求...
英文:
<p>have you checked out the OAuth2 package? I've used it for user-authorised calls, and hacked it around a bit to allow it to handle multiple authorisation sources.</p><p>I haven't tested it with pure server-to-server comms, but you should be able to hack the transport code to get it to do what it needs...</p>

这可能有点晚了，但我还没有找到一个好的例子来帮助人们入门。
在开始之前，请确保你：
安装了 Go 1.5
安装了 Google Cloud SDK（cloud.google.com/sdk - 这将允许本地开发）
在你的 Google App Engine / Cloud 控制台中创建了一个服务账号，并下载了 JSON 文件（API 和身份验证 > 凭据）
一旦上述设置完成：
设置一个路径，指向你之前下载的安全凭据
export GOOGLE_APPLICATION_CREDENTIALS=~/DIRECTORY/CREDENTIALS.json
现在你可以使用 Go 进行身份验证。
package mainimport ("fmt""golang.org/x/net/context""golang.org/x/oauth2/google"analytics "google.golang.org/api/analytics/v3")var (scope = analytics.AnalyticsReadonlyScope)func main() {// 在本地运行时，身份验证由 gcloud 工具提供；在 Compute Engine 上运行时，由相关的服务账号提供。client, err := google.DefaultClient(context.Background(), scope)if err != nil {fmt.Printf("无法获取默认客户端：%v", err)}service, err := analytics.New(client)if err != nil {fmt.Printf("无法创建存储服务：%v", err)}fmt.Println(service)}
希望对你有帮助！
英文:
this might be a little late but I havent found a good example to get people started.
Before you start make sure you
> install golang 1.5
> install google cloud SDK (cloud.google.com/sdk - this will allow for local development)
> Create a service account in your google appengine / cloud console and download the json (API's and auth > Credentials )
Once above is setup:
> set a path for your security credentials that you downloaded earlier
>export GOOGLE_APPLICATION_CREDENTIALS=~/DIRECTORY/CREDENTIALS.json
now you can authenticate with go.
package mainimport ("fmt""golang.org/x/net/context""golang.org/x/oauth2/google"analytics "google.golang.org/api/analytics/v3")var (scope = analytics.AnalyticsReadonlyScope)func main() {// Authentication is provided by the gcloud tool when running locally, and// by the associated service account when running on Compute Engine.client, err := google.DefaultClient(context.Background(), scope)if err != nil {fmt.Printf("Unable to get default client: %v", err)}service, err := analytics.New(client)if err != nil {fmt.Printf("Unable to create storage service: %v", err)}fmt.Println(service)}
