X509TrustManager.java

package com.util.wxutil;
    
    import javax.net.ssl.X509TrustManager;
    import java.security.cert.CertificateException;
    import java.security.cert.X509Certificate;
    
    /** * 证书信任管理器（用于https请求） * Created by admin on 2017/11/14. */
    public class MyX509TrustManager implements X509TrustManager { 
        //检查客户端证书
        public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
        }
    
        //检查服务器端证书
        public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
        }
    
        //返回受信任的x509数组
        public X509Certificate[] getAcceptedIssuers() {
            return null;
        }
    }

HttpsRequest.java  
这边是要传递三个参数 URL 请求方式 参数

package com.util.wxutil;
    
    
    import javax.net.ssl.HttpsURLConnection;
    import javax.net.ssl.SSLContext;
    import javax.net.ssl.SSLSocketFactory;
    import javax.net.ssl.TrustManager;
    import java.io.BufferedReader;
    import java.io.InputStream;
    import java.io.InputStreamReader;
    import java.io.OutputStream;
    import java.net.URL;
    import java.security.SecureRandom;
    
    /** * Created by admin on 2017/11/14. */
    public class HttpsREQUEST { 
        /** * 发送https请求 * * @param requestUrl * 请求地址 * @param requestMethod * 请求方式（GET、POST） * @param outStr * 提交的数据 * @return JSONObject(通过JSONObject.get(key)的方式获取json对象的属性值) */
        public static String HttpsRequest(String requestUrl, String requestMethod, String outStr) throws Exception{
    // 创建 SSLContext
            SSLContext sslContext = SSLContext.getInstance("SSL","SunJSSE");
            TrustManager[] trustManagers = {
       new MyX509TrustManager()};
    // 初始化
            sslContext.init(null,trustManagers,new SecureRandom());
    // 获取 sslSocketFactory 对象
            SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();
    // 设置当前实例使用
    
            StringBuffer buffer = null;
    // 传递的URL
            URL url = new URL(requestUrl);
            HttpsURLConnection connection = (HttpsURLConnection)url.openConnection();
    // 请求方式
            connection.setRequestMethod(requestMethod);
            connection.setDoOutput(true);
            connection.setDoInput(true);
            connection.setSSLSocketFactory(sslSocketFactory);
            connection.connect();
    
            if (outStr != null){
                OutputStream outputStream = connection.getOutputStream();
                outputStream.write(outStr.getBytes("utf-8"));
                outputStream.close();
            }
    
    // 读取服务端内容
            InputStream inputStream = connection.getInputStream();
            InputStreamReader inputStreamReader = new InputStreamReader(inputStream,"utf-8");
            BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
            buffer = new StringBuffer();
            String line = null;
            while((line = bufferedReader.readLine()) != null){
                buffer.append(line);
            }
    // System.out.println(buffer.toString());
            return buffer.toString();
        }
    
    }

下班了，这边潦草了点，不好意思；但是代码亲测，没有问题
