java - 从 Android 到 php 输入的 json

Question

我正在尝试将数据作为 json 从 Android 发布到 PHP 脚本，但它似乎无法读取我发送的数据。

PHP

header('Content-type: application/json');
$json = file_get_contents('php://input');
print_r($json);

数据

{"Date":"2012-05-31","Device_ID":"soaptester","Time":"15:22:59","Longitude":0.33,"Latitude":51.01}

Java

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    sp = getSharedPreferences("SoapTester", Context.MODE_PRIVATE);
    setContentView(R.layout.main);
    String address = sp.getString("address", null);
    if (address == null) {
        sp.edit().putString("address", "http://192.168.0.8/lt_data/test.php").commit();
    }

    addressTextView = (EditText) findViewById(R.id.address);
    addressTextView.setOnEditorActionListener(new TextView.OnEditorActionListener() {

        @Override
        public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
            sp.edit().putString("address", String.valueOf(v.getText())).commit();
            return true;
        }
    });

    track = new LocationTrack();
    track.setDate("2012-05-31");
    track.setTime("15:22:59");
    track.setLatitude(51.01);
    track.setLongitude(0.33);
    track.setDevice_ID("soaptester");

    output = new Gson().toJson(track);

    outputTextView = (TextView) findViewById(R.id.output);
    outputTextView.setText(output);

}

@Override
protected void onResume() {
    super.onResume();
    addressTextView.setText(sp.getString("address", ""));
}

public void sendPost(View view) {

    ServiceResponse r = Resting.post(sp.getString("address", ""), 80, output, EncodingTypes.UTF8);
    ((TextView)findViewById(R.id.response)).setText(String.valueOf(r));

}

经过大量测试后，我似乎无法找出为什么它没有从 Android 应用程序接收数据。

也许尝试使用一些工具(例如 netcat)来查看您是否正确发送了 json 消息。或者尝试使用一些网络流量工具(wireshark、tcpdump)。
