Android 关于Https 请求问题

[a291318254]

String str = "https://pay.vivo.com.cn/vivoPay/getVivoOrderNum";
URL url = new URL(str);

SSLContext sslctxt = SSLContext.getInstance("TLS");

sslctxt.init(null, new TrustManager[]{new MyX509TrustManager()}, new java.security.SecureRandom());

HttpsURLConnection conn = (HttpsURLConnection)url.openConnection();

conn.setDoOutput(true);
//获取输出流
OutputStream outputStream = conn.getOutputStream();
//对外写数据
outputStream.write(entity); //entity是我传递的具体参数

conn.setSSLSocketFactory(sslctxt.getSocketFactory());

conn.setHostnameVerifier(new MyHostnameVerifier());

conn.connect();

int respCode = conn.getResponseCode(); //最后respCode 返回了400，应该怎么写？

我认为这个参数是要加在URL后面的,如 https://pay.vivo.com.cn/vivoPay/getVivoOrderNum?a=1&b=2
