请教httpclient访问https，我的步骤错哪里了

参考技术A /**
* 发起https请求并获取结果
*
* @param requestUrl
* 请求地址
* @param requestMethod
* 请求方式（GET、POST）
* @param outputStr
* 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 JSONObject httpRequest(String requestUrl,
String requestMethod, String outputStr)
JSONObject jsonObject = null;
StringBuffer buffer = new StringBuffer();
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", "SunJSSE");
sslContext.init(null, tm, new java.security.SecureRandom());
// 从上述SSLContext对象中得到SSLSocketFactory对象
SSLSocketFactory ssf = sslContext.getSocketFactory();

URL url = new URL(requestUrl);
HttpsURLConnection httpUrlConn = (HttpsURLConnection) url
.openConnection();
httpUrlConn.setSSLSocketFactory(ssf);

httpUrlConn.setDoOutput(true);
httpUrlConn.setDoInput(true);
httpUrlConn.setUseCaches(false);
// 设置请求方式（GET/POST）
httpUrlConn.setRequestMethod(requestMethod);

if ("GET".equalsIgnoreCase(requestMethod))
httpUrlConn.connect();

// 当有数据需要提交时
if (null != outputStr)
OutputStream outputStream = httpUrlConn.getOutputStream();
// 注意编码格式，防止中文乱码
outputStream.write(outputStr.getBytes("UTF-8"));
outputStream.close();


// 将返回的输入流转换成字符串
InputStream inputStream = httpUrlConn.getInputStream();
InputStreamReader inputStreamReader = new InputStreamReader(
inputStream, "utf-8");
BufferedReader bufferedReader = new BufferedReader(
inputStreamReader);

String str = null;
while ((str = bufferedReader.readLine()) != null)
buffer.append(str);

bufferedReader.close();
inputStreamReader.close();
// 释放资源
inputStream.close();
inputStream = null;
httpUrlConn.disconnect();
jsonObject = JSONObject.fromObject(buffer.toString());
catch (ConnectException ce)
log.error("Weixin server connection timed out.");
catch (Exception e)
log.error("https request error:", e);

return jsonObject;
