英文:
Google Cloud Storage Client App error using Go Runtime Google App Engine
问题
我正在尝试从这个链接中使用示例代码，并尝试在Go运行时使用Google Cloud Storage客户端应用程序对Google Cloud Storage进行操作，但是示例代码中的以下部分出现错误***“无法将c（类型“appengine”。Context）用作函数参数中的context.Context类型：*** “appengine”。Context未实现context.Context（缺少Deadline方法）”
c := appengine.NewContext(r)
hc := &http.Client{
Transport: &oauth2.Transport{
Source: google.AppEngineTokenSource(c, storage.ScopeFullControl),
Base: &urlfetch.Transport{Context: c},
},
}
这里有什么问题？我该如何解决？
英文:
Im trying the example code from this link and trying to do operations on
Google Cloud Storage using Google Cloud Storage Client App from Go runtime , But the following part in the sample code is giving the error "cannot use c (type "appengine".Context) as type context.Context in function argument: "appengine".Context does not implement context.Context (missing Deadline method)"
c := appengine.NewContext(r)
hc := &http.Client{
Transport: &oauth2.Transport{
Source: google.AppEngineTokenSource(c, storage.ScopeFullControl),
Base: &urlfetch.Transport{Context: c},
},
}
Whats the issue here ?? How can i solve this ??

错误消息明确指出，您尝试传递的值的类型是 appengine.Context，而期望的类型是 context.Context。
google.AppEngineTokenSource() 函数期望的是类型为 context.Context 的值，而不是您传递的类型为 appengine.Context 的值。
您可以使用以下函数创建这样的 Context：
cloud.NewContext(projID string, c *http.Client)
这是我会这样做：
c := appengine.NewContext(r)
hc := &http.Client{}
ctx := cloud.NewContext(appengine.AppID(c), hc)
hc.Transport = &oauth2.Transport{
Source: google.AppEngineTokenSource(ctx, storage.ScopeFullControl),
Base: &urlfetch.Transport{Context: c},
}
英文:
The error message clearly states that you try to pass a value of type appengine.Context where the expected type is context.Context.
The google.AppEngineTokenSource() function expects a value of type context.Context and not the one you pass (which is of type appengine.Context).
You can create such Context with the function:
cloud.NewContext(projID string, c *http.Client)
This is how I would do it:
c := appengine.NewContext(r)
hc := &http.Client{}
ctx := cloud.NewContext(appengine.AppID(c), hc)
hc.Transport = &oauth2.Transport{
Source: google.AppEngineTokenSource(ctx, storage.ScopeFullControl),
Base: &urlfetch.Transport{Context: c},
}

你需要按照这里的说明，从appengine更新到google.golang.org/appengine：https://github.com/golang/oauth2/#app-engine
英文:
You need to update from appengine to google.golang.org/appengine as described there: https://github.com/golang/oauth2/#app-engine
