一、前言

HTTPS （全称：Hyper Text Transfer Protocol over SecureSocket Layer），是以安全为目标的 HTTP 通道，在HTTP的基础上通过传输加密和身份认证保证了传输过程的安全性 [1]  。HTTPS 在HTTP 的基础下加入SSL 层，HTTPS 的安全基础是 SSL，因此加密的详细内容就需要 SSL。 HTTPS 存在不同于 HTTP 的默认端口及一个加密/身份验证层（在 HTTP与 TCP 之间）。这个系统提供了身份验证与加密通讯方法。

本文使用okhttp3访问SpringBoot创建的https接口。

二、软件版本

SpringBoot:2.1.2

okhttp3:3.2.0

keytool:jdk1.8.0_77

三、单向认证

1生成服务端证书

keytool -genkey -alias server -keypass 123456 -keyalg RSA -keysize 1024 -validity 365 -storepass 123456 -storetype PKCS12 -keystore C:\Users\admin\Desktop\server.p12

记住秘钥库口令，在SpringBoot配置中使用

2导出服务端cer证书

keytool -export -alias server -keystore C:\Users\admin\Desktop\server.p12 -storetype PKCS12 -keypass 123456 -file C:\Users\admin\Desktop\server.cer

3配置SpringBoot

将server.p12拷贝到SpringBoot的resources目录

#ssl配置
server.ssl.enabled=true
server.ssl.key-store=classpath:server.p12
server.ssl.key-store-password=123456
server.ssl.key-store-type=JKS
# 证书别名
server.ssl.key-alias=server

4浏览器测试

访问https://localhost:8080/demo

5okhttp3测试

path：者指定server.cer的路径

package com.asyf.demo.other_api.okhttp3;

import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;

import javax.net.ssl.*;
import java.io.File;
import java.io.FileInputStream;
import java.io.InputStream;
import java.security.KeyStore;
import java.security.SecureRandom;
import java.security.cert.Certificate;
import java.security.cert.CertificateFactory;

/**

public class Test2 {

    //安全传输层协议
    private static final String PROTOCOL = "TLS";

    // JKS/PKCS12
    private static final String KEY_KEYSTORE_TYPE = "PKCS12";

    private static SSLSocketFactory getSocketFactory(String cerPath) throws Exception {
        SSLSocketFactory socketFactory = null;
        try (InputStream cerInputStream = new FileInputStream(new File(cerPath))) {
            TrustManager[] trustManagers = getTrustManagers(cerInputStream);
            SSLContext sslContext = getSslContext(trustManagers);
            socketFactory = sslContext.getSocketFactory();
        }
        return socketFactory;
    }

    private static SSLContext getSslContext(TrustManager[] trustManagers) throws Exception {
        SSLContext sslContext = SSLContext.getInstance(PROTOCOL);
        sslContext.init(null, trustManagers, new SecureRandom());
        return sslContext;
    }

    private static TrustManager[] getTrustManagers(InputStream inputStream) throws Exception {
        TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
        KeyStore keyStore = KeyStore.getInstance(KEY_KEYSTORE_TYPE);
        //加载证书
        CertificateFactory certificateFactory = CertificateFactory.getInstance("X.509");
        Certificate ca = certificateFactory.generateCertificate(inputStream);
        keyStore.load(null, null);
        //设置公钥
        keyStore.setCertificateEntry("server", ca);
        trustManagerFactory.init(keyStore);
        TrustManager[] trustManagers = trustManagerFactory.getTrustManagers();
        return trustManagers;
    }

    public static void main(String[] args) throws Exception {
        //获取SSLSocketFactory
        String certPath = "D:\\workspace\\asyf_demo\\demo\\src\\main\\java\\com\\asyf\\demo\\other_api\\okhttp3\\server.cer";//服务端公钥
        SSLSocketFactory socketFactory = getSocketFactory(certPath);
        //发送请求
        String url = "https://127.0.0.1:8080/demo";
        OkHttpClient.Builder clientBuilder = new OkHttpClient.Builder();
        clientBuilder.sslSocketFactory(socketFactory);
        //解决报错javax.net.ssl.SSLPeerUnverifiedException: Hostname 127.0.0.1 not verified
        clientBuilder.hostnameVerifier(new HostnameVerifier() {
            @Override
            public boolean verify(String s, SSLSession sslSession) {
                System.out.println("主机:" + s);
                return true;
            }
        });
        OkHttpClient client = clientBuilder.build();

        Request.Builder builder = new Request.Builder().url(url);
        Request request = builder.build();

        Response response = client.newCall(request).execute();
        String result = response.body().string();
        //打印请求结果
        System.out.println(result);
    }

}

四、双向认证

1生成客户端证书

keytool -genkey -alias client -keypass 123456 -keyalg RSA -keysize 1024 -validity 365 -storepass 123456 -storetype PKCS12 -keystore C:\Users\admin\Desktop\client.p12

2导出客户端cer证书

keytool -export -alias client -keystore C:\Users\admin\Desktop\client.p12 -storetype PKCS12 -keypass 123456 -file C:\Users\admin\Desktop\client.cer

3生成keystore用来存储springboot信任的证书

keytool -genkey -alias springboot_keystore -keypass 123456 -keyalg RSA -keysize 1024 -validity 365 -storepass 123456 -storetype PKCS12 -keystore C:\Users\admin\Desktop\springboot_keystore.keystore

4导入客户端的公钥到springboot_keystore.keystore

keytool -import -v -file C:\Users\admin\Desktop\client.cer -keystore C:\Users\admin\Desktop\springboot_keystore.keystore -storepass 123456

5配置SpringBoot

将springboot_keystore.keystore拷贝到SpringBoot项目，并添加如下配置

#双向认证配置
server.ssl.trust-store=classpath:springboot_keystore.keystore
server.ssl.trust-store-password=123456
server.ssl.client-auth=need
server.ssl.trust-store-type=JKS
server.ssl.trust-store-provider=SUN

6浏览器测试

直接访问会出现如下错误

需要在电脑中安装证书

双击client.p12，安装证书（demo是win10环境）

安装成功后刷新浏览器，提示选择证书。点击“确定”。

然后访问https接口，看到如下图的结果，说明配置成功。

7okhttp3测试

path：指定client.p12的路径

如果使用单向认证的main函数继续访问，控制台打印异常信息：

Exception in thread "main" javax.net.ssl.SSLHandshakeException: Received fatal alert: bad_certificate

测试代码：
