Question

Hye，我的Android应用程序有问题。此应用程序用于扫描来自信标和eddystone的数据，数据将保存到本地文件和服务器。我使用齐射字符串请求方法来获取数据，并不确定这是否正确.apk已成功构建但我的服务器没有收到数据。它只是空白。非常感谢你们能帮助我。

这是我发送数据的mainactivity.java部分。

private void stopScanning(Button scanButton) {

    try {
        beaconManager.stopRangingBeaconsInRegion(region);
    } catch (RemoteException e) {
            // TODO - OK, what now then?
    }
    String scanData = logString.toString();
    if (scanData.length() > 0)
    {
        String url = "http://beaconscanner.byethost33.com/insertbeacondata.php";

        StringRequest postRequest = new StringRequest(Request.Method.POST, url,
                new Response.Listener<String>() {
                    @Override
                    public void onResponse(String response) {

                    }
                },
                new Response.ErrorListener() {
                    @Override
                    public void onErrorResponse(VolleyError error) {

                    }
                }
        ) {
            @Override
            protected Map<String, String> getParams()
            {
                Map<String,String> params = new HashMap<String, String>();
                // the POST parameters:

                params.put("scanInterval",PREFERENCE_SCANINTERVAL);
                params.put("timestamp",PREFERENCE_SCANINTERVAL);
                params.put("power",PREFERENCE_POWER);
                params.put("proximity",PREFERENCE_PROXIMITY);
                params.put("rssi",PREFERENCE_RSSI);
                params.put("majorMinor",PREFERENCE_MAJORMINOR);
                params.put("uuid",PREFERENCE_UUID);
                params.put("index",PREFERENCE_INDEX);
                params.put("location",PREFERENCE_LOCATION);
                params.put("realTimelog",PREFERENCE_REALTIME);
                return params;
            }
        };
        Volley.newRequestQueue(this).add(postRequest);
// Write file
        fileHelper.createFile(scanData);
        // Display file created message.
        Toast.makeText(getBaseContext(),
                "File saved to:" + getFilesDir().getAbsolutePath(),
                Toast.LENGTH_SHORT).show();
        scanButton.setText(MODE_STOPPED);

    } else {
        // We didn't get any data, so there's no point writing an empty file.
        Toast.makeText(getBaseContext(),
                "No data captured during scan, output file will not be created.",
                Toast.LENGTH_SHORT).show();
        scanButton.setText(MODE_STOPPED);
    }
}

这是php编码：

if($_SERVER['REQUEST_METHOD']=='POST'){
 $dataScan = $_POST["scanInterval"];
 $dataTime = $_POST["timestamp"];
 $dataPower = $_POST["power"];
 $dataProx = $_POST["proximity"];
 $dataRssi = $_POST["rssi"];
 $dataMajmin = $_POST["majorMinor"];
 $dataUuid = $_POST["uuid"];
 $dataIndex = $_POST["index"];
 $dataLoc = $_POST["location"];
 $dataReal = $_POST["realTimeLog"];

 $conn = new mysqli($servername, $username, $password, $dbname);   
 if ($conn->connect_error) 
 { 
  die("Connection failed: " . $conn->connect_error); 
 }   
 $sql = "INSERT INTO beaconscanner (scanInterval, timestamp, power, proximity, rssi, majorMinor, uuid, index, location, 
realTimelog) VALUES ('$dataScan', '$dataTime', '$dataPower', '$dataProx', '$dataRssi', '$dataMajmin', '$dataUuid', '$dataIndex', 
'$dataLoc', '$dataReal',)";  

 if ($conn->query($sql) === TRUE)  
 { 
  echo "Record updated successfully"; 
 }  
 else  
 { 
  echo "Error updating record: " . $conn->error; 
 }  
 $conn->close();  
 } 
?>

PHP服务器没有收到从Android应用程序发送的数据
