Question

我正在非常糟糕的时间试图找出我的代码中的错误来实现android应用程序和php服务器之间的连接。

以下是我在服务器上的php代码：

<?php 
$json = file_get_contents('php://input');
$request = json_decode($json, true);
$response = array();
print "PHP HERE!";
// check for required fields
if (isset($request['Year']) && isset($request['Month']) && isset($request['Day_of_month']) && isset($request['Day_of_week']) && isset($request['Hour']) && isset($request['Minute'])) {

    $Year= $request['Year'];
    $Month= $request['Month'];
    $Day_of_month= $request['Day_of_month'];
    $Day_of_week= $request['Day_of_week'];
    $Hour= $request['Hour'];
    $Minute= $request['Minute'];

    // include db connect class
    require_once 'db_connect.php';

    // connecting to db
    $db = new DB_CONNECT();

    // mysql inserting a new row
    $result = mysql_query("INSERT INTO date VALUES('$Year','$Month','$Day_of_month','$Day_of_week','$Hour','$Minute')");

    $response["success"] = 1;
    echo json_encode($response);
    exit;
}
?>

我的客户端代码如下：

// Making HTTP request
try {
    // Open connection to URL and perform POST request.
    URL url1 = new URL(url);
    HttpURLConnection urlConnection = (HttpURLConnection) url1.openConnection();
    urlConnection.setDoOutput(true); // Set Http method to POST
    urlConnection.setDoInput(true);
    urlConnection.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
    urlConnection.setRequestMethod("POST");
    urlConnection.setChunkedStreamingMode(0); // Use default chunk size

    // Write serialized JSON data to output stream.
    OutputStreamWriter writer = new OutputStreamWriter(urlConnection.getOutputStream());
    //OutputStream out = new BufferedOutputStream(urlConnection.getOutputStream());
    //BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(out, "UTF-8"));
    writer.write(params.toString());
    writer.flush();
    writer.close();

    InputStream input = urlConnection.getInputStream();
    BufferedReader reader = new BufferedReader(new InputStreamReader(input));
    //BufferedReader reader = new BufferedReader(new InputStreamReader(
    //        is, "iso-8859-1"), 8);
    StringBuilder result = new StringBuilder();
    String line;

    while ((line = reader.readLine()) != null) {
        result.append(line);
    }
    jObj = new JSONObject(result.toString());
} catch (Exception e) {
    Log.e("Buffer Error", "Error converting result " + e.toString());
}

// return JSON String
return jObj;

请感谢任何帮助。
