嘗試將圖像從android上傳到我的服務器

Question

正在使用此代碼將圖像上傳到我的Web服務器：

    public void send (View view)
    {
        HttpURLConnection connection = null;
        DataOutputStream outputStream = null;
        DataInputStream inputStream = null;

        String pathToOurFile = "sdcard/yo.jpg";
        String urlServer = "http://192.168.1.4/uplaod.php";
        String lineEnd = "\r\n";
        String twoHyphens = "--";
        String boundary = "*****";

        int bytesRead, bytesAvailable, bufferSize;
        byte[] buffer;
        int maxBufferSize = 1 * 1024 * 1024;

        try {
            FileInputStream fileInputStream = new FileInputStream(new File(pathToOurFile));

            URL url = new URL(urlServer);
            connection = (HttpURLConnection) url.openConnection();

            // Allow Inputs & Outputs
            connection.setDoInput(true);
            connection.setDoOutput(true);
            connection.setUseCaches(false);

            // Enable POST method
            connection.setRequestMethod("POST");

            connection.setRequestProperty("Connection", "Keep-Alive");
            connection.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);

            outputStream = new DataOutputStream(connection.getOutputStream());
            outputStream.writeBytes(twoHyphens + boundary + lineEnd);
            outputStream.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + pathToOurFile + "\"" + lineEnd);
            outputStream.writeBytes(lineEnd);

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

            // Read file
            bytesRead = fileInputStream.read(buffer, 0, bufferSize);

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

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

            // Responses from the server (code and message)
            int serverResponseCode = connection.getResponseCode();
            String serverResponseMessage = connection.getResponseMessage();

            fileInputStream.close();
            outputStream.flush();
            outputStream.close();

            Log.i("ODPOWIEDZ", serverResponseMessage);
            Context context = getApplicationContext();
            Toast.makeText(context, "its here 1 ", Toast.LENGTH_LONG).show();
        } catch (Exception ex) {
            Context context = getApplicationContext();
            Toast.makeText(context, "its in catsh", Toast.LENGTH_LONG).show();
            Log.i("WYJATEK", ex.getMessage());
        }

    }

我從LogCat收到此消息，這里的問題在哪里？

59-124 / system_process D / SntpClient：請求時間失敗：java.net.SocketException：協議不支持地址族

這是我的PHP文件

<?php
    $target_path  = "uploadedfile/";
    $target_path = $target_path . basename( $_FILES['uploadedfile']['name']);

    if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
        echo "The file ".  basename( $_FILES['uploadedfile']['name'])." has been uploaded";
    } 
    else {
        echo "There was an error uploading the file, please try again!";
    }
?>

Answer 1

SNTP錯誤與時間協議有關，順便說一句，它與您的應用程序無關。 看起來這只是模擬器嘗試從ntp服務器獲取最新時間戳。 只是丟棄它。

問題仍然是另外一回事。 您確實注意到php腳本的名稱中可能有錯字？ 在您的代碼中，您將其稱為uplaod.php 。

另外，請確保您已在清單文件中啟用了Internet訪問：

<uses-permission android:name="android.permission.INTERNET"></uses-permission>
