golang https server如何设计方便抓包定位且安全

代码
测试

用go写后端https服务时，需要定位https包中的内容是否符合预期。

有涉猎的朋友应该了解过https有一种keylog技术，它允许在HTTPS连接中捕获和记录SSL或TLS会话密钥，以便于调试和分析加密流量。

本文将的就是通过可控制开启和关闭的keylog功能，提供安全便捷的调试方法。

代码
服务端代码如下

package main

 import ("crypto/tls""github.com/gin-gonic/gin""hbp_common/Base""io""log""net/http""os""path/filepath")var tlsConfig *tls.Configvar keylogpath stringconst (ApiCertPath = "/root/testssl/cert.pem"ApikeyPath  = "/root/testssl/key.pem")func main() {route := gin.Default()route.GET("/hello", func(c *gin.Context) {c.JSON(http.StatusOK, gin.H{"result": "word"})})ListenAndSeverTls(route)}func SetEnableKeyLog(ctx *gin.Context) {enable := ctx.Param("enable")if enable == "enable" {var err errortlsConfig.KeyLogWriter, err = KeyLogWrite(keylogpath)if err != nil {ctx.AbortWithStatus(http.StatusForbidden)return}} else if enable == "disable" {tlsConfig.KeyLogWriter = nilerr := os.RemoveAll(keylogpath)if err != nil {ctx.AbortWithStatus(http.StatusForbidden)return}} else {ctx.AbortWithStatus(http.StatusBadRequest)return}ctx.Status(http.StatusOK)}func KeyLogWrite(path string) (io.Writer, error) {keyLogFile, err := os.OpenFile(path, os.O_WRONLY|os.O_CREATE|os.O_APPEND, 0666)if err != nil {log.Fatal(err.Error())}return keyLogFile, err}func ListenAndSeverTls(route *gin.Engine) {defer Base.SafePanic()keylogpath = filepath.Dir(ApiCertPath) + "/keylog"// 加载证书和密钥cert, err := tls.LoadX509KeyPair(ApiCertPath, ApikeyPath)if err != nil {log.Panic("ListenAndSeverTls failed!
