xutils框架在访问网络时如何像HttpURLConnection一样携带json数据

[陌简曦东]

HttpURLConnection携带数据代码：

URL url;
		HttpURLConnection connection = null;
		int flag = 0;
		try {
			String userIpAddress = "http://" + "124.207.158.74" + ":" + "60022"
					+ "/";
			url = new URL(userIpAddress + APIurl);
			connection = (HttpURLConnection) url.openConnection();
			// 连接主机超时
			connection.setConnectTimeout(100000); // 2015.4.10 add by gaosi
			// 设置从主机读取数据超时
			connection.setReadTimeout(100000);
			connection.setDoInput(true);
			connection.setDoOutput(true);
			connection.setRequestMethod("PUT");
			connection.setRequestProperty("Content-Type",
					"application/x-www-form-urlencoded");
			connection.setRequestProperty("Charset", "utf-8");
			connection.setUseCaches(false);
			JSONObject obj = new JSONObject();
			try {
				obj.put("Username", user.getUsername());
				obj.put("Password", user.getPassword());
				obj.put("Logindevice", user.getLogindevice());
				obj.put("System", user.getSystem());
			} catch (JSONException e) {
				flag = 5;
				return flag;
			}
			// obj.put("Appkey", user.getKey());
			// Log.v("Login", user.getKey());
			DataOutputStream out = new DataOutputStream(
					connection.getOutputStream());
			out.writeBytes(obj.toString());
			out.flush();
			out.close();

一般会有类似addParams的方法，携带访问参数。
