獲得來自請求PHP響應Android中

Question

我有這樣的代碼在我的Android proyect一個的AsyncTask將文件上傳到服務器與PHP：

URL url = new URL(args[1]); 
connection = (HttpURLConnection) url.openConnection(); 
connection.setDoInput(true); 
connection.setDoOutput(true); 
connection.setUseCaches(false); 
connection.setRequestMethod("POST"); 
connection.setRequestProperty("Connection", "Keep-Alive"); 
connection.setRequestProperty("ENCTYPE", "multipart/form-data"); 
connection.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary); 
connection.setRequestProperty("uploaded_file", args[0]); 

dataOutputStream = new DataOutputStream(connection.getOutputStream()); 

dataOutputStream.writeBytes(twoHyphens + boundary + lineEnd); 
dataOutputStream.writeBytes("Content-Disposition: form-data; name=\"uploaded_file\";filename=\"" + args[0] + "\"" + lineEnd); 

dataOutputStream.writeBytes(lineEnd); 

bytesAvailable = fileInputStream.available(); 
bufferSize = Math.min(bytesAvailable,maxBufferSize); 
buffer = new byte[bufferSize]; 
bytesRead = fileInputStream.read(buffer,0,bufferSize); 

while (bytesRead > 0){ 
    dataOutputStream.write(buffer,0,bufferSize); 
    bytesAvailable = fileInputStream.available(); 
    bufferSize = Math.min(bytesAvailable,maxBufferSize); 
    bytesRead = fileInputStream.read(buffer,0,bufferSize); 
} 

dataOutputStream.writeBytes(lineEnd); 
dataOutputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd); 

serverResponseCode = connection.getResponseCode(); 
String serverResponseMessage = connection.getResponseMessage(); 

Log.d(TAG, "Server Response is: " + serverResponseMessage + ": " + serverResponseCode); 


fileInputStream.close(); 
dataOutputStream.flush(); 
dataOutputStream.close(); 

這是在服務器端的PHP代碼：

$file_path = "./uploads/"; 
$file_path = $file_path . basename($_FILES['uploaded_file']['name']); 
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)){ 
    echo "success"; 
} else{ 
    echo "fail"; 
} 

一切工作正常，該文件被上載正確，但服務器唯一的反應給我的代碼線以下：

Log.d(TAG, "Server Response is: " + serverResponseMessage + ": " + serverResponseCode); 

是：

服務器響應是：OK：200

或者：

服務器的迴應是：未找到：404

我想要得到的字符串「成功」和「失敗」出現在服務器端，我該怎麼做？提前致謝。

Answer 1

呀HttpUrlConnection#getResponseMessage只是返回HTTP響應消息（即200 = HTTP OK）使用不同的功能，如connection.getContent()或循環。你想要做的是這樣的：

BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream())); 


// read the contents of the connection from the bufferedreader 

Answer 2

.getResponseMessage()是HTTP狀態消息，而不是請求的輸出。

需要超過connection.getInputStream()

serverResponseCode = connection.getResponseCode(); 
String serverResponseMessage = connection.getResponseMessage(); 
String serverResponseContent = connection.getContent();
