java - 简单的 android 和 ASP.NET 组合

Question

我编写了一个 Android 应用程序，用于将文本数据发送到 ASP.NET Web 服务器。我正在使用下一个代码通过 Http 发送数据:

try {
    URL url = new URL(serverUrl);
    connection = (HttpURLConnection)url.openConnection();
    connection.setDoInput(true);
    connection.setDoOutput(true);
    connection.setUseCaches(false);

    // Enable POST method
    connection.setRequestMethod("POST");

    connection.setRequestProperty("Connection", "Keep-Alive");
    connection.setRequestProperty("Content-Type", "text/plain; charset=utf-8");
    output = new DataOutputStream(connection.getOutputStream());
    String finalUri = sendedUrl.replace("gaburl", "");
    output.writeChars(finalUri);
    //Toast.makeText(context, finalUri, 1000).show();
    output.flush();
    output.close();
}
catch(Exception e) {
    Toast.makeText(context, e.toString(), 5);
}

如何接收和显示通过 ASP.NET 应用程序中的方法发送的数据 output.writeChars(finalUri) 方法？ 此过程应该执行就像下面的描述:

1)我们有 asp.net 表单，它们是之前描述的发送者 android 方法的目标；

2)表单应该读取发送给它的字符串数据并显示它。

请帮忙
