无可扩展服务代理转发的X-Endpoint-API-UserInfo标头

Question

我正在使用Google Cloud Endpoints和Google Cloud Functions以及Google ID令牌身份验证来建立一个宠物项目。我已经按照this和this指南进行设置，但是X-Endpoint-API-UserInfo标头没有传递给云函数。

我在this OpenAPI Yaml中设置了一个POST端点。它已部署到Cloud Endpoints，以及可扩展服务代理。当我使用gcloud auth application-default print-access-token生成的令牌从Postman调用此代码时，我发现身份验证确实有效，但是该函数中仅包含以下标头：host, user-agent, transfer-encoding, accept, accept-encoding, authorization, cache-control, forwarded, function-execution-id, postman-token, x-appengine-city, x-appengine-citylatlong, x-appengine-country, x-appengine-default-version-hostname, x-appengine-https, x-appengine-region, x-appengine-request-log-id, x-appengine-user-ip, x-cloud-trace-context, x-forwarded-for, x-forwarded-proto, x-real-ip, connection

您能帮我为什么我不能从功能中的ESP获取用户信息吗？

Answer 1

我刚刚确认ESP确实将X-Endpoint-Api-Userinfo标头发送到后端功能。

这是我的后端代码

cat hello.go 
// Package helloworld provides a set of Cloud Functions samples.
package helloworld

import (
        "encoding/json"
        "fmt"
        "html"
        "net/http"
)

// HelloHTTP is an HTTP Cloud Function with a request parameter.
func HelloHTTP(w http.ResponseWriter, r *http.Request) {
        for key, vals := range r.Header {
                for _, val := range vals {
                        resp := fmt.Sprintf("request-headers: %s=%s\n", key, val)
                        w.Write([]byte(resp))
                }
        }
        var d struct {
                Name string `json:"name"`
        }
        if err := json.NewDecoder(r.Body).Decode(&d); err != nil {
                fmt.Fprint(w, "Hello, World!")
                return
        }
        if d.Name == "" {
                fmt.Fprint(w, "Hello, World!")
                return
        }
        fmt.Fprintf(w, "Hello, %s!\n", html.EscapeString(d.Name))
}

这里是后端的标题
