java请求https，在本地可以，在服务器端请求失败，是服务器端失败哦！
自己的前提是请求的url是正确的。
附上https请求代码，请大神一看：
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();
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;
}
