绝对好用的。直用的这个，GOOD LUCK FOR YOU

public static String 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();
System.out.println("返回的数据："+buffer.toString());
// 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 buffer.toString();
}追问需要用证书？否则会拒绝访问的。。。

追答再搞个代理类，就OK了。

证书验证 注册在服务器或者jre中就可以了吧 这样没有证书 直接不能访问
