Mac中使用Mitmproxy/Charles拦截移动设备网络请求（抓包）

背景

拦截http proxy的软件很多，如 Fiddler，Charles等，能够实现对http通信的拦截，可以查验Request和Response参数，特别是移动设备快速普及，此类软件逐渐被用于移动设备APP的网络请求拦截。

Mitmproxy的使用

官网

安装方式

brew install mitmproxy

启动

mitmweb

清空请求

点击mitmproxy 点击new 可将所有的请求清空

拦截Https请求

如今很多APP都开始使用Https请求，以确保数据安全，默认无法拦截https的接口，这时我们就要配置证书。

需要电脑和手机端都安装证书

Mac安装证书

找到证书位置

cd ~
cd .mitmproxy
open ./

双击安装其中的mitmproxy-ca-cert.pem文件即可

Android安装证书

在你的移动设备上打开连接，或者扫描下面的二维码，下载相应证书，然后安装。

Android 手机可以在“设置–>安全–>从SD卡安装证书”中安装刚才下载的证书。

不用的Android位置不一样，我们可以搜索从SD卡安装找到对应的配置，选择下载的证书安装即可。

下载的位置默认在Downloads文件夹中。

Charles的使用

下载地址百度云链接

密码:5v9y

Mac端安装证书

1. 安装证书

Help–>SSL Proxying–>Install Charles Root Certificate安装即可

2. 配置需要证书的域名

Proxy–>SSL Proxying Settings–>SSL Proxying

中添加域名 比如

• Host:*.baidu.com
• Port:443

Android安装证书

Help–>SSL Proxying–>Install Charles Root Certificate on a Mobile Device or Remote Browser

• 设置手机代理 比如我的是192.168.2.1:8888

• 在浏览器中打开 http://chls.pro/ssl 或者扫描如下二维码

  

• 下载证书后安装 安装方式参见上文

代码中的配置

Retrofit/okhttp

客户端不对服务器证书做任何验证

public static SSLSocketFactory getSSLSocketFactory() throws Exception {
    //创建一个不验证证书链的证书信任管理器。
    final TrustManager[] trustAllCerts = new TrustManager[]{new X509TrustManager() {
    @Override
    public void checkClientTrusted(
        java.security.cert.X509Certificate[] chain,
        String authType) throws CertificateException {
    }

    @Override
    public void checkServerTrusted(
        java.security.cert.X509Certificate[] chain,
        String authType) throws CertificateException {
    }

    @Override
    public java.security.cert.X509Certificate[] getAcceptedIssuers() {
        return new java.security.cert.X509Certificate[0];
    }
    }};

    // Install the all-trusting trust manager
    final SSLContext sslContext = SSLContext.getInstance("TLS");
    sslContext.init(null, trustAllCerts,new java.security.SecureRandom());
    // Create an ssl socket factory with our all-trusting manager
    return sslContext.getSocketFactory();
}

//使用自定义SSLSocketFactory
private void onHttps(OkHttpClient.Builder builder) {
    try {             
        builder.sslSocketFactory(getSSLSocketFactory()).hostnameVerifier(org.apache.http.conn.ssl.SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
    } catch (Exception e) {
    e.printStackTrace();
    }
}   

客户端验证证书

public static SSLSocketFactory getSSLSocketFactory() throws Exception {
    // Create a trust manager that does not validate certificate chains
    final TrustManager[] trustAllCerts = new TrustManager[]{new X509TrustManager() {
        //证书中的公钥
        public static final String PUB_KEY = "输入您的公钥";

        @Override
        public void checkClientTrusted(
                java.security.cert.X509Certificate[] chain,
                String authType) throws CertificateException {
        }

        //客户端并为对ssl证书的有效性进行校验
        @Override
        public void checkServerTrusted(
                java.security.cert.X509Certificate[] chain,
                String authType) throws CertificateException {
            if (chain == null) {
                throw new IllegalArgumentException("checkServerTrusted:x509Certificate array isnull");
            }

            if (!(chain.length > 0)) {
                throw new IllegalArgumentException("checkServerTrusted: X509Certificate is empty");
            }

            if (!(null != authType && authType.equalsIgnoreCase("RSA"))) {
                throw new CertificateException("checkServerTrusted: AuthType is not RSA");
            }

            // Perform customary SSL/TLS checks
            try {
                TrustManagerFactory tmf = TrustManagerFactory.getInstance("X509");
                tmf.init((KeyStore) null);
                for (TrustManager trustManager : tmf.getTrustManagers()) {
                    ((X509TrustManager) trustManager).checkServerTrusted(chain, authType);
                }
            } catch (Exception e) {
                throw new CertificateException(e);
            }
            // Hack ahead: BigInteger and toString(). We know a DER encoded Public Key begins
            // with 0×30 (ASN.1 SEQUENCE and CONSTRUCTED), so there is no leading 0×00 to drop.
            RSAPublicKey pubkey = (RSAPublicKey) chain[0].getPublicKey();

            String encoded = new BigInteger(1 /* positive */, pubkey.getEncoded()).toString(16);
            // Pin it!
            final boolean expected = PUB_KEY.equalsIgnoreCase(encoded);

            if (!expected) {
                throw new CertificateException("checkServerTrusted: Expected public key: "
                        + PUB_KEY + ", got public key:" + encoded);
            }
        }

        @Override
        public java.security.cert.X509Certificate[] getAcceptedIssuers() {
            return new java.security.cert.X509Certificate[0];
        }
    }};

    // Install the all-trusting trust manager
    final SSLContext sslContext = SSLContext.getInstance("TLS");
    sslContext.init(null, trustAllCerts,new java.security.SecureRandom());
    // Create an ssl socket factory with our all-trusting manager
    return sslContext.getSocketFactory();

OkGo

客户端不对服务器证书做任何验证

OkHttpClient.Builder builder = new OkHttpClient.Builder();
HttpsUtils.SSLParams sslParams1 = HttpsUtils.getSslSocketFactory();
builder.sslSocketFactory(sslParams1.sSLSocketFactory, sslParams1.trustManager);
