一、启动https
beego实现https，通过配置文件conf/app.conf，加入https相关配置

EnableDocs = true
EnableHTTPS=true
EnableHttpTLS = true
HttpsPort = 8010
HTTPSCertFile = "conf/server.crt"
HTTPSKeyFile = "conf/server.key"

二、如何实现https的双向认证
我们都是知道，c/s 架构中，一般都是https单向认证模式，那么如何实现双向认证呢？
查看beego的官方文档并没有找到开启双向认证的地方，通过查看beego源码，具体实现在beego–>app.go里，在beego–>config.go 文件中发现相关配置参数，如下：

// Listen holds for http and https related config
type Listen struct {Graceful          bool // Graceful means use graceful module to start the serverServerTimeOut     int64ListenTCP4        boolEnableHTTP        boolHTTPAddr          stringHTTPPort          intAutoTLS           boolDomains           []stringTLSCacheDir       stringEnableHTTPS       boolEnableMutualHTTPS bool          --> 开启双向认证HTTPSAddr         stringHTTPSPort         intHTTPSCertFile     stringHTTPSKeyFile      stringTrustCaFile       string        --> 配置ca证书ClientAuth        tls.ClientAuthTypeEnableAdmin       boolAdminAddr         stringAdminPort         intEnableFcgi        boolEnableStdIo       bool // EnableStdIo works with EnableFcgi Use FCGI via standard I/O
}

同步conf/app.conf中添加如下配合

EnableMutualHTTPS=true        --> 启用双向认证
EnableHttpTLS = true
HttpsPort = 8010
HTTPSCertFile = "conf/server.crt"
HTTPSKeyFile = "conf/server.key"
TrustCaFile = "conf/ca.crt"   --> 配置ca.crt证书

三、服务端开启双向认证，客户端也要有相应的实现

import ("crypto/tls""crypto/x509""fmt""io/ioutil""net/http"
)
var CA_CRT string = "conf/ca.crt"
var CLIENT_CRT string = "conf/client.crt"
var CLIENT_KEY string = "conf/client.key"func main() {pool := x509.NewCertPool()caCertPath := CA_CRTcaCrt, err := ioutil.ReadFile(caCertPath)if err != nil {fmt.Println("ReadFile err:", err)return}pool.AppendCertsFromPEM(caCrt)cliCrt, err := tls.LoadX509KeyPair(CLIENT_CRT, CLIENT_KEY)if err != nil {fmt.Println("Loadx509keypair err:", err)return}tr := &http.Transport{TLSClientConfig: &tls.Config{RootCAs:      pool,Certificates: []tls.Certificate{cliCrt},},}client := &http.Client{Transport: tr}resp, err := client.Get("https://127.0.0.1:8010")if err != nil {fmt.Println("Get error:", err)return}defer resp.Body.Close()body, err := ioutil.ReadAll(resp.Body)fmt.Println(string(body))
}
