Java通过OKHttp发送https请求（忽略认证）

封装：

package gj.okhttp3;

import okhttp3.OkHttpClient;

import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSocketFactory;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
import java.security.KeyManagementException;
import java.security.NoSuchAlgorithmException;

    public static OkHttpClient.Builder buildOKHttpClient() {
        try {
            TrustManager[] trustAllCerts = buildTrustManagers();
            final SSLContext sslContext = SSLContext.getInstance("SSL");
            sslContext.init(null, trustAllCerts, new java.security.SecureRandom());

            final SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();

        }
    }

        };
    }
