Mux或http。HandleFunc甚至还在为Google App Engine上的helloworld端点工作

我无法让名为EmptySucces的处理程序工作。我正在将sendgrid转变为appspot微服务。目前为止打电话给

http://localhost:8080/emptysuccess

退货

404找不到页面

此行为为true dev\u appserver。py和真实的appspot。com。如何获得/清空成功?

package sendmail

import (
    "fmt"
    "github.com/sendgrid/sendgrid-go"
    "net/http"
    "google.golang.org/appengine"
    "github.com/gorilla/mux"
    "google.golang.org/appengine/log"

)

func main() {
    r := mux.Router{}
    r.HandleFunc("/send", sendhardcoded)
    r.HandleFunc("/emptysuccess", emptysuccess)
    //appengine.Main() // Starts the server to receive requests
}

func emptysuccess(w http.ResponseWriter, r *http.Request) {
    fmt.Println(w, "Hello Success")

}

func sendhardcoded(w http.ResponseWriter, r *http.Request) {
    ctx := appengine.NewContext(r)

    log.Infof(ctx, "Running Sendhardcoded")
    request := sendgrid.GetRequest("SG.OYPDF6hA.zk_XibKbJEUVLQfrkY-SBu5FejFakeC9ODFv1bE", "/v3/mail/send", "https://api.sendgrid.com")
    request.Method = "POST"
    request.Body = []byte(` {
    "personalizations": [
        {
            "to": [
                {
                    "email": "darian.hickman@gmail.info"
                }
            ],
            "subject": "Sending with SendGrid is Fun"
        }
    ],
    "from": {
        "email": "darian.hickman@ccc.com"
    },
    "content": [
        {
            "type": "text/plain",
            "value": "and easy to do anywhere, even with Go"
        }
    ]
}`)
    response, err := sendgrid.API(request)
    if err != nil {
        log.Errorf(ctx, "Problems: %v" ,err)
    } else {
        fmt.Println(w, response.StatusCode)
        fmt.Println(w, response.Body)
        fmt.Println(w, response.Headers)
        fmt.Println(w, "Sendmail should have worked")
    }
}

还要确保所有请求都转到go app my app。yaml是:

runtime: go
api_version: go1.9

handlers:

- url: /static
  static_dir: static

- url: /.*
  script: _go_app
  login: required
  secure: always

以下是最终奏效的方法: 我修复了mkopriva指出的mux代码。(注意:http.handleFunc而不是http.Handle不起作用)。我不得不将main()改为init(),然后应用引擎确认了我的mux设置。

因此,基本上我学到了go应用程序引擎本身无法处理多个处理程序的艰难方法,我在设置mux时搞砸了。

工作代码:

package sendmail

import (
    "fmt"
    _"github.com/sendgrid/sendgrid-go"
    "net/http"
    "google.golang.org/appengine"
    "github.com/gorilla/mux"
    "google.golang.org/appengine/log"

)

func init() {
    r := mux.NewRouter()
    r.HandleFunc("/send", sendhardcoded)
    r.HandleFunc("/emptysuccess", emptysuccess)
    //appengine.Main() // Starts the server to receive requests
    http.Handle("/", r)
}

func emptysuccess(w http.ResponseWriter, r *http.Request) {
    fmt.Println(w, "Hello Success")

}

func sendhardcoded(w http.ResponseWriter, r *http.Request) {
    ctx := appengine.NewContext(r)

    log.Infof(ctx, "Running Sendhardcoded")

}
