GO Server用法及代碼示例

GO語言"net/http/httptest"包中"Server"類型的用法及代碼示例。

服務器是在本地環回接口上的 system-chosen 端口上偵聽的 HTTP 服務器，用於端到端 HTTP 測試。

用法:

type Server struct {
    URL      string // base URL of form http://ipaddr:port with no trailing slash
    Listener net.Listener

    // EnableHTTP2 controls whether HTTP/2 is enabled
    // on the server.It must be set between calling
    // NewUnstartedServer and calling Server.StartTLS.
    EnableHTTP2 bool // Go 1.14

    // TLS is the optional TLS configuration, populated with a new config
    // after TLS is started.If set on an unstarted server before StartTLS
    // is called, existing fields are copied into the new config.
    TLS *tls.Config

    // Config may be changed after calling NewUnstartedServer and
    // before Start or StartTLS.
    Config *http.Server
    // contains filtered or unexported fields
}

例子：

package main

import (
    "fmt"
    "io"
    "log"
    "net/http"
    "net/http/httptest"
)

func main() {
    ts := httptest.NewServer(http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
        fmt.Fprintln(w, "Hello, client")
    }))
    defer ts.Close()

    res, err := http.Get(ts.URL)
    if err != nil {
        log.Fatal(err)
    }
    greeting, err := io.ReadAll(res.Body)
    res.Body.Close()
    if err != nil {
        log.Fatal(err)
    }

    fmt.Printf("%s", greeting)
}

輸出：

Hello, client

示例(HTTP2)：

package main

import (
    "fmt"
    "io"
    "log"
    "net/http"
    "net/http/httptest"
)

func main() {
    ts := httptest.NewUnstartedServer(http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
        fmt.Fprintf(w, "Hello, %s", r.Proto)
    }))
    ts.EnableHTTP2 = true
    ts.StartTLS()
    defer ts.Close()

    res, err := ts.Client().Get(ts.URL)
    if err != nil {
        log.Fatal(err)
    }
    greeting, err := io.ReadAll(res.Body)
    res.Body.Close()
    if err != nil {
        log.Fatal(err)
    }
    fmt.Printf("%s", greeting)

}

輸出：

Hello, HTTP/2.0
