Question

当我将任务发送到任务队列时，它会一直失败并在日志中显示http 404（未找到）错误。

该项目已针对灵活的云端任务alpha列入白名单。

我可以将HTTP post请求发送到/ endpointpath＆amp; / tasks / worker本地没有任何错误。

端点正常工作，并将任务添加到任务队列。

 13:37:41.300 POST 200 0 B 422 ms curl/7.54.0 /endpointspath?key=keyremoved 0.0.0.0 - "POST endpointspath?key=keyremoved" 200 undefined "-" "curl/7.54.0"

该应用程序作为默认服务运行。

app.go main func：

func main() {
    r := mux.NewRouter()

    r.HandleFunc("/", handler)

    r.HandleFunc("/_ah/health", healthCheckHandler)

    // Task handlers

    r.Path("/tasks/worker").Methods("POST", "GET", "PUT").HandlerFunc(workerTaskHandler)

    // Endpoints

    r.Path("/endpointpath").Methods("POST").HandlerFunc(searchHandler)

    http.Handle("/", r)

    port := 8080
    if portStr := os.Getenv("PORT"); portStr != "" {
        port, _ = strconv.Atoi(portStr)
    }
    log.Fatal(http.ListenAndServe(fmt.Sprintf(":%d", port), nil))
}

缩写为app.yaml：

runtime: go
env: flex

handlers:
- url: /tasks/.*
  script: _go_app
- url: /.*
  script: _go_app

当队列向工作人员发送请求时记录HTTP 404响应：

10.0.0.1 - "POST /tasks/worker" 404 200 "-" "AppEngine-Google; (+http://code.google.com/appengine)"

}

我最接近GAE来找到任务/工人网址是通过在app.yaml中设置login：admin（即使tho flex也不使用它进行身份验证）。这将返回403未经授权的错误。

handlers:
- url: /tasks/.*
  script: _go_app
  login: admin

以下是日志中的403响应

 httpRequest: {
  latency:  "0s"    
  referer:  "-"    
  remoteIp:  "10.0.0.1"

  requestUrl:  "/tasks/worker"    
  responseSize:  "162"

 }

}

不确定它是否相关，但projectname.appspot.com/_ah/health会返回此错误：

{
 "code": 5,
 "message": "Method does not exist.",
 "details": [
  {
   "@type": "type.googleapis.com/google.rpc.DebugInfo",
   "stackEntries": [],
   "detail": "service_control"
  }
 ]
}

事实证明，端点不能与任务处理程序在同一服务上运行。如果ESP代理在灵活环境中运行相同的服务，并且该服务启用了端点服务，则ESP代理将阻止任务处理程序URL请求。

在单独的服务上运行任务处理程序，不要设置＆＃34; endpoints_api_service：＆＃34;在任务处理程序服务app.yaml文件中。

这样做会阻止队列在灵活环境中分派给工作人员。

在app引擎文档中没有提到这有点奇怪。

＆＃34; / _ ah / health＆＃34;问题是由于未在open api文件中设置此路径引起的。如果未设置此路径，则代理不会识别该网址。
