從Android應用程序發送數據到Php

我在本地網絡上的WAMP服務器上運行的php表單...但是當我嘗試運行該文件時，它給了我截圖中的錯誤。我試圖從我的Android應用程序發送數據到Php表單。在按下「發送」按鈕從Android應用程序發送數據到Php

我已經確定也是我的Android應用程序崩潰：

兩個WAMP和Android應用程序都在同一網絡上
我也試圖直接訪問從Android上的網址瀏覽器，它帶來了頁面，所以URL不應該是一個麻煩
我試過使用一個真實的設備和它的相同的錯誤。
我還在Android Manifest中添加了INTERNET權限！

enter image description here

PHP代碼：

<?php 
// get the "message" variable from the post request 
// this is the data coming from the Android app 
$message=$_POST["message"]; 
// specify the file where we will save the contents of the variable message 
$filename="androidmessages.html"; 
// write (append) the data to the file 
file_put_contents($filename,$message."<br />",FILE_APPEND); 
// load the contents of the file to a variable 
$androidmessages=file_get_contents($filename); 
// display the contents of the variable (which has the contents of the file) 
echo $androidmessages; 
?>

這裏是Android應用程序的代碼：

public class HelloWorldActivity extends Activity { 

    Button sendButton; 

    EditText msgTextField; 

    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) 
    { 
     super.onCreate(savedInstanceState); 
     // load the layout 
     setContentView(R.layout.main);   

     // make message text field object 
     msgTextField = (EditText) findViewById(R.id.msgTextField); 
     // make send button object 
     sendButton = (Button) findViewById(R.id.sendButton); 

    } 

    // this is the function that gets called when you click the button 
    public void send(View v) 
    { 
     // get the message from the message text box 
     String msg = msgTextField.getText().toString(); 

     // make sure the fields are not empty 
     if (msg.length()>0) 
     { 
      HttpClient httpclient = new DefaultHttpClient(); 
      HttpPost httppost = new HttpPost("http://192.168.0.40/yourPhpScript.php"); 
     try { 
      List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2); 
      nameValuePairs.add(new BasicNameValuePair("id", "12345")); 
      nameValuePairs.add(new BasicNameValuePair("message", msg)); 
      httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 
      httpclient.execute(httppost); 
      msgTextField.setText(""); // clear text box 
     } catch (ClientProtocolException e) { 
      // TODO Auto-generated catch block 
     } catch (IOException e) { 
      // TODO Auto-generated catch block 
     } 

     } 
     else 
     { 
      // display message if text fields are empty 
      Toast.makeText(getBaseContext(),"All field are required",Toast.LENGTH_SHORT).show(); 
     } 

    } 
}

編輯1：這是根據要求提供原代碼

使用'AsyncTask'將數據發佈到服務器 – 2015-02-11 02:15:53

@язык：謝謝你的建議。但我想知道我要去哪裏錯了 – user3828453 2015-02-11 02:27:13

如果應用程序崩潰，然後添加logcat結果的問題，以檢查問題的位置 – 2015-02-11 02:33:30

我想這應該爲你在你的Android代碼，這方面的工作，改變http請求，

private void startHttpRequest() 
    { 
    try 
    { 
     new Thread(new Runnable() 
     { 
      public void run() 
      { 

      // get the message from the message text box 
      String msg = msgTextField.getText().toString(); 

      // make sure the fields are not empty 
      if (msg.length()>0) 
      { 
       HttpClient httpclient = new DefaultHttpClient(); 
       HttpPost httppost = new     HttpPost("http://192.168.0.40/yourPhpScript.php"); 
       try 
       { 
       StringEntity se = new StringEntity("id=12345&message="+msg); 
       httppost.setEntity(se); 
       HttpResponse response = httpclient.execute(httppost); 
       msgTextField.setText(""); // clear text box 

       StatusLine statusLine = response.getStatusLine(); 
       if(statusLine.getStatusCode() == HttpStatus.SC_OK) 
       { 
       ByteArrayOutputStream out = new ByteArrayOutputStream(); 
       response.getEntity().writeTo(out); 

       //* this should be the return from your php script $androidmessages 
       String responseString = out.toString(); 
       out.close(); 
       } 
       } 
       catch (ClientProtocolException e) 
       { 
        // TODO Auto-generated catch block 
       } 
       catch (IOException e) { 
        // TODO Auto-generated catch block 
       } 
      } 
      } 
     }).start(); 

    } 
    catch(Exception e) 
    { 
    } 
    }

然後更改代碼在你php腳本，

<?php 
// get the "message" variable from the post request 
// this is the data coming from the Android app 
$id=$_REQUEST["id"]; 
$message=$_REQUEST["message"]; 
// specify the file where we will save the contents of the variable message 
$filename="androidmessages.html"; 
// write (append) the data to the file 
file_put_contents($filename,$message."<br />",FILE_APPEND); 
// load the contents of the file to a variable 
$androidmessages=file_get_contents($filename); 
// display the contents of the variable (which has the contents of the file) 
echo $androidmessages; 
?>

謝謝我正在嘗試你的代碼，但我需要導入什麼庫，以使「response.getStatusLine ）「工作....它說響應無法解決 – user3828453 2015-02-11 04:35:31

對不起，延遲，我的答案缺失的項目讓我修復它，這應該回答你的問題 – faljbour 2015-02-11 14:34:11

謝謝我會檢查它，並讓你回到......我也應該在同一個目錄中創建一個名爲「androidmessages.html」的文件嗎？或者它會爲我創造，如果萬一它沒有找到？另外如果我創建它，我需要在它內部有一些HTML代碼或保存它只是空白？ – user3828453 2015-02-11 23:18:05

首先，確保你的PHP腳本是正確的。然後，刪除該按鈕的XML配置中的'onClick'。使用下面的代碼。它會工作

public class HelloWorldActivity extends Activity { 

    Button sendButton; 

    EditText msgTextField; 

    /** 
    * Called when the activity is first created. 
    */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     // load the layout 
     setContentView(R.layout.main); 

     // make message text field object 
     msgTextField = (EditText) findViewById(R.id.msgTextField); 
     // make send button object 
     sendButton = (Button) findViewById(R.id.sendButton); 

     sendButton.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       // check for empty message 
       if (msgTextField.getText().toString().trim().length() > 0) { 
        new sendMessage().execute(); 
       } else { 
        // display message if text fields are empty 
        Toast.makeText(HelloWorldActivity.this, "All field are required", Toast.LENGTH_SHORT).show(); 
       } 
      } 
     }); 

    } 

    private class sendMessage extends AsyncTask<String, String, String> { 

     ProgressDialog dialog; 

     @Override 
     protected void onPreExecute() { 
      super.onPreExecute(); 
      dialog = new ProgressDialog(HelloWorldActivity.this); 
      dialog.setIndeterminate(true); 
      dialog.setMessage("Sending Message..."); 
      dialog.setCancelable(false); 
      dialog.show(); 

     } 

     @Override 
     protected String doInBackground(String... params) { 


      // get the message from the message text box 
      String msg = msgTextField.getText().toString(); 

      // desired URL 
      final String mURL = "http://192.168.0.40/yourPhpScript.php"; 

      // Create a new HttpClient and Post Header 
      HttpClient httpclient = new DefaultHttpClient(); 
      HttpPost httppost = new HttpPost(mURL); 
      HttpResponse response; 

      // Add data 
      List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(); 

      nameValuePairs.add(new BasicNameValuePair("id", "12345")); 
      nameValuePairs.add(new BasicNameValuePair("message", msg)); 


      try { 
       httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 
       response = httpclient.execute(httppost); 
       String responseBody = EntityUtils 
         .toString(response.getEntity()); 
       Log.d("Http Post Response:", responseBody); 

      } catch (ClientProtocolException e) { 
       // TODO Auto-generated catch block 
      } catch (IOException e) { 
       // TODO Auto-generated catch block 
      } 
      return null; 
     } 

     @Override 
     protected void onPostExecute(String s) { 
      super.onPostExecute(s); 
      dialog.dismiss(); 

      // Toast user for a successful operation 
      Toast.makeText(HelloWorldActivity.this, "Message sent successfully", Toast.LENGTH_LONG).show(); 

      // clear text box 
      msgTextField.setText(""); 

     } 
    } 


}
