https请求数据，ca机构安全证书

有两种方法请求参数，一种是信任所有https的请求，一种是带证书的验证并请求

首先写bean类，之后需要写拦截器，这个类可以直接复制

public class LogInterceptor implements Interceptor {

    public static String TAG = "LogInterceptor";

    @Override
    public Response intercept(Chain chain) throws IOException {
        Request request = chain.request();
        long startTime = System.currentTimeMillis();
        Response response = chain.proceed(chain.request());
        long endTime = System.currentTimeMillis();
        long duration=endTime-startTime;
        MediaType mediaType = response.body().contentType();
        String content = response.body().string();
        Log.d(TAG,"\n");
        Log.d(TAG,"----------Start----------------");
        Log.d(TAG, "| "+request.toString());
        String method=request.method();
        if("POST".equals(method)){
            StringBuilder sb = new StringBuilder();
            if (request.body() instanceof FormBody) {
                FormBody body = (FormBody) request.body();
                for (int i = 0; i < body.size(); i++) {
                    sb.append(body.encodedName(i) + "=" + body.encodedValue(i) + ",");
                }
                sb.delete(sb.length() - 1, sb.length());
                Log.d(TAG, "| RequestParams:{"+sb.toString()+"}");
            }
        }
        Log.d(TAG, "| Response:" + content);
        Log.d(TAG,"----------End:"+duration+"毫秒----------");
        return response.newBuilder()
                .body(ResponseBody.create(mediaType, content))
                .build();
    }
}

不要忘记写联网权限和写入SD卡的权限
之后在MainActivity类中的onCreate（）方法里面写

// loadData();//信任所有https的请求：第一种实现
  cardData();//带证书验证

在方法外面写这两个方法，缺啥补啥，已经注释了，这是两种方法来请求数据。一定要看清注解

/**
 * 带证书验证
 */
private void cardData() {

    FormBody formbody = new FormBody.Builder().add("mobile", "13717830672").add("password", "123456").build();
    Request request = new Request.Builder().url("https://www.zhaoapi.cn/user/login").post(formbody).build();

    //带证书验证里的方法
    setCard().newCall(request).enqueue(new Callback() {
        @Override
        public void onFailure(Call call, IOException e) {

        }

        @Override
        public void onResponse(Call call, Response response) throws IOException {
            if(response.isSuccessful() && response != null && response.body() != null){
                final String result;
                try {
                    result = response.body().string();
                    Gson gson = new Gson();
                    Bean bean = gson.fromJson(result, Bean.class);
                    Bean.DataBean data = bean.getData();
                    String mobile = data.getMobile();
                    System.out.println("登录的手机号mobile = " + mobile);


                }catch (Exception e){

                }
            }
        }
    });

}

//带证书验证里的方法
public OkHttpClient setCard() {
    OkHttpClient.Builder builder = new OkHttpClient.Builder();
    try {
        CertificateFactory certificateFactory = CertificateFactory.getInstance("X.509");
        KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType());
        keyStore.load(null);
        String certificateAlias = Integer.toString(0);
        keyStore.setCertificateEntry(certificateAlias, certificateFactory.generateCertificate(getAssets().open("zhaoapi_server.cer")));//拷贝好的证书
        SSLContext sslContext = SSLContext.getInstance("TLS");
        final TrustManagerFactory trustManagerFactory =
                TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
        trustManagerFactory.init(keyStore);
        sslContext.init
                (
                        null,
                        trustManagerFactory.getTrustManagers(),
                        new SecureRandom()
                );
        builder.sslSocketFactory(sslContext.getSocketFactory());
        builder.addInterceptor(new LogInterceptor());//拦截器
        builder.hostnameVerifier(new HostnameVerifier() {

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

    @Override
    public X509Certificate[] getAcceptedIssuers() {

    }

    @Override

如果是带证书的验证，需要在main文件下创建asstes,然后将ca证书复制到里面。
