https请求，get post 通用

public static String sendPostHttps(String url,String param){
   PrintWriter out = null;
   BufferedReader in = null;
   String result = "";
   try {
      // 创建SSLContext对象，并使用我们指定的信任管理器初始化
      TrustManager[] tm = { new MyX509TrustManager() };
      SSLContext sslContext = SSLContext.getInstance("SSL");
      sslContext.init(null, tm, new java.security.SecureRandom());

      // 从上述SSLContext对象中得到SSLSocketFactory对象
      SSLSocketFactory ssf = sslContext.getSocketFactory();
      // 打开和URL之间的连接
      URL realUrl = new URL(url);
      HttpsURLConnection conn = (HttpsURLConnection) realUrl.openConnection();
      conn.setSSLSocketFactory(ssf);
      // 设置通用的请求属性
      conn.setRequestProperty("accept", "*/*");
      conn.setRequestProperty("connection", "Keep-Alive");
      conn.setRequestProperty("content-Type", "application/json");
      conn.setRequestProperty("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");
      // 发送POST请求必须设置如下两行
      conn.setDoOutput(true);
      conn.setDoInput(true);
      // 获取URLConnection对象对应的输出流
      out = new PrintWriter(conn.getOutputStream());
      // 发送请求参数
      out.print(param);
      // flush输出流的缓冲
      out.flush();
      // 定义BufferedReader输入流来读取URL的响应
      in = new BufferedReader(
            new InputStreamReader(conn.getInputStream()));
      String line;
      while ((line = in.readLine()) != null) {
         result += line;
      }
      System.out.println("-----result-----"+result);
   } catch (Exception e) {
      e.printStackTrace();
   } finally {// 使用finally块来关闭输出流、输入流
      try {
         if (out != null) {
            out.close();
         }
         if (in != null) {
            in.close();
         }
      } catch (IOException ex) {
         ex.printStackTrace();
      }
   }
   return result;
}









调用如下

post请求

String mobileString = "{\"openId\":\""+openId+"\"}";
JSONObject parse = JSONObject.parseObject(sendPostHttps(url, mobileString));
String loginToken = parse.getJSONObject("data").getString("result");
return loginToken;


如果要是get请求   没有参数 

JSONObject parse = JSONObject.parseObject(sendPostHttps(url,null));
String loginToken = parse.getJSONObject("data").getString("result");
return loginToken;
