改正如下代码，要求可以正常运行package main import ( "fmt" "github.com/gin-gonic/gin" ) func TestMW(c *gin.Context) { c.String(200, "hello,%s", "ghz") } func MyMiddleware1(c *gin.Context) { fmt.Println("我的第一个中间件") } func MyMiddleware2(c *gin.Context) { fmt.Println("我的第二个中间件") } func main() { /* func Default() *Engine { debugPrintWARNINGDefault() engine := New() engine.Use(Logger(), Recovery()) return engine } */ // e := gin.Default() // e := gin.New() e := gin.Default() e.Use(MyMiddleware1, MyMiddleware2) e.GET("testmw", TestMW) e.Run() }

你需要将 MyMiddleware1 和 MyMiddleware2 函数的参数类型改为 gin.HandlerFunc，代码如下：

package main

import (
	"fmt"

	"github.com/gin-gonic/gin"
)

func TestMW(c *gin.Context) {
	c.String(200, "hello,%s", "ghz")
}

func MyMiddleware1() gin.HandlerFunc {
	return func(c *gin.Context) {
		fmt.Println("我的第一个中间件")
		c.Next()
	}
}

func MyMiddleware2() gin.HandlerFunc {
	return func(c *gin.Context) {
		fmt.Println("我的第二个中间件")
		c.Next()
	}
}

func main() {
	e := gin.Default()
	e.Use(MyMiddleware1(), MyMiddleware2())
	e.GET("testmw", TestMW)
	e.Run()
}

其中 MyMiddleware1 和 MyMiddleware2 函数需要返回一个 gin.HandlerFunc 类型的函数，这个返回的函数才能被 gin 使用。在返回的函数中，我们需要手动调用 c.Next()，以便让请求继续往下执行。

package main import ( "fmt" "net/http" "github.com/gin-gonic/gin" ) func main() { r := gin.Default() r.GET("/user", func(c *gin.Context) { name := c.Query("name") c.String(http.StatusOK, fmt.Sprintf("hello %s", name)) }) r.Run() } 上面代码使用了Gin框架，请写出请求链接，以测试程序的有效性。

请求链接为：http://localhost:8080/user?name=yourname。其中，localhost:8080为服务器地址和端口号，user为路由路径，name为查询参数，yourname为具体的参数值。你可以将yourname替换为任意字符串，然后在浏览器中访问该链接，即可得到响应结果。

将以上代码拆分为多个模块，可以按照以下方式进行组织：

**main.go：**

package main

import (
	"github.com/gin-gonic/gin"
	"net/http"
)

func main() {
	router := gin.Default()
	router.POST("/webhook", handleWebhook)
	router.Run(":8080")
}

**alert.go：**

package main

type AlertData struct {
	Receiver          string            `json:"receiver"`
	Status            string            `json:"status"`
	Alerts            []Alert           `json:"alerts"`
	GroupLabels       map[string]string `json:"groupLabels"`
	CommonLabels      map[string]string `json:"commonLabels"`
	CommonAnnotations map[string]string `json:"commonAnnotations"`
	ExternalURL       string            `json:"externalURL"`
}

type Alert struct {
	Status      string            `json:"status"`
	Labels      map[string]string `json:"labels"`
	Annotations map[string]string `json:"annotations"`
}

**webhook.go：**

package main

import (
	"bytes"
	"encoding/json"
	"fmt"
	"github.com/gin-gonic/gin"
	"net/http"
)

func handleWebhook(c *gin.Context) {
	var alertData AlertData

	err := c.BindJSON(&alertData)
	if err != nil {
		c.JSON(http.StatusBadRequest, gin.H{"error": "Error decoding JSON"})
		return
	}

	// Process the received alert data
	for _, alert := range alertData.Alerts {
		// Extract information from alert
		alertName := alert.Labels["alertname"]
		instance := alert.Labels["instance"]
		severity := alert.CommonLabels["severity"]
		description := alert.Annotations["description"]
		summary := alert.Annotations["summary"]

		// Compose the message to be sent to Enterprise WeChat group using Markdown format
		message := fmt.Sprintf(`**Alert Name:** %s
**Instance:** %s
**Severity:** %s
**Description:** %s
**Summary:** %s`,
			alertName, instance, severity, description, summary)

		// Send the message to Enterprise WeChat group using the WeChat bot API
		sendToEnterpriseWeChatGroup(message)
	}

	c.JSON(http.StatusOK, gin.H{"message": "Alerts processed successfully"})
}

**wechat.go：**

package main

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

func sendToEnterpriseWeChatGroup(message string) {
	// Replace 'YOUR_WECHAT_BOT_URL' with the actual URL of your Enterprise WeChat bot
	wechatBotURL := "YOUR_WECHAT_BOT_URL"

	data := map[string]interface{}{
		"msgtype": "markdown",
		"markdown": map[string]string{
			"content": message,
		},
	}

	jsonData, _ := json.Marshal(data)

	_, err := http.Post(wechatBotURL, "application/json", bytes.NewReader(jsonData))
	if err != nil {
		fmt.Println("Error sending message to Enterprise WeChat group:", err)
	}
}

通过将不同功能的代码拆分到不同的模块中，可以更好地组织代码，提高代码的可读性和可维护性。在`main.go`中导入其他模块，并在适当的地方调用相应的函数即可。
