英文:
http.Request has undefined fields when deploying to appengine
问题
我正在开发一个网络应用程序，我依赖以下代码进行身份验证（我使用github.com/dgrijalva/jwt-go包）：
func ValidateProtectedPage(protectedPage http.HandlerFunc) http.HandlerFunc {
return http.HandlerFunc(func(res http.ResponseWriter, req *http.Request) {
// 如果没有设置Auth cookie，则返回404 not found
cookie, err := req.Cookie("Auth")
if err != nil {
Forbidden(res)
return
}
// 使用cookie返回一个Token
token, err := jwt.ParseWithClaims(cookie.Value, &Claims{}, func(token *jwt.Token) (interface{}, error) {
// 确保token的签名未被更改
if _, ok := token.Method.(*jwt.SigningMethodHMAC); !ok {
return nil, fmt.Errorf("Unexpected siging method")
}
return []byte(util.Secret), nil
})
if err != nil {
Forbidden(res)
return
}
// 获取token的声明并将其传递给原始请求
if claims, ok := token.Claims.(*Claims); ok && token.Valid {
ctx := context.WithValue(req.Context(), "Auth", *claims)
protectedPage(res, req.WithContext(ctx))
} else {
Forbidden(res)
}
})
}
问题是，我试图将我的应用部署到appengine上，但是我遇到了以下错误：
planilla-go/controllers/auth.go:45: req.Context undefined (type *http.Request has no field or method Context)
planilla-go/controllers/auth.go:46: req.WithContext undefined (type *http.Request has no field or method WithContext)
根据我所了解，这是由于appengine的请求与go库中的请求不兼容导致的，但我还没有找到解决方法。
有没有办法包装或转换http.Request以使用appengine的请求呢？
英文:
I'm working on a web app and I depend on the following code for authentication (I'm using github.com/dgrijalva/jwt-go package):
func ValidateProtectedPage(protectedPage http.HandlerFunc) http.HandlerFunc {
return http.HandlerFunc(func(res http.ResponseWriter, req *http.Request) {
// If no Auth cookie is set then return a 404 not found
cookie, err := req.Cookie("Auth")
if err != nil {
Forbidden(res)
return
}
// Return a Token using the cookie
token, err := jwt.ParseWithClaims(cookie.Value, &Claims{}, func(token *jwt.Token) (interface{}, error) {
// Make sure token's signature wasn't changed
if _, ok := token.Method.(*jwt.SigningMethodHMAC); !ok {
return nil, fmt.Errorf("Unexpected siging method")
}
return []byte(util.Secret), nil
})
if err != nil {
Forbidden(res)
return
}
// Grab the tokens claims and pass it into the original request
if claims, ok := token.Claims.(*Claims); ok && token.Valid {
ctx := context.WithValue(req.Context(), "Auth", *claims)
protectedPage(res, req.WithContext(ctx))
} else {
Forbidden(res)
}
})}
The issue is, that I'm trying to deploy my app to appengine, and I get the following errors:
planilla-go/controllers/auth.go:45: req.Context undefined (type *http.Request has no field or method Context)
planilla-go/controllers/auth.go:46: req.WithContext undefined (type *http.Request has no field or method WithContext)
From what I read this is due to incompatibilities between appengine's requests and those from go's library, but I couldn't find a workaround yet
Is there a way to wrap or convert the http.Request to use appengine's instead?

Appengine只支持Go 1.6。这有点令人困惑，因为它使我的应用程序无法使用，需要进行重大的兼容性改造，但这是当前平台的状态。

Appengine only supports Go 1.6. A bit baffling since it renders my app useless without a major compat overhaul, but that's the current state of the platform
