java - 安卓，http : How to upload a file to a site hosted by a shared server?

Question

我给自己买了一个网站，该网站托管在一台使用 cpanel 共享一个 IP 地址的 linux 服务器上。现在的问题是，我想使用此代码将文件上传到我的网站。每次我使用像 www.site 这样的站点地址时，我都会收到一个异常，提示该 URL 格式错误。当我使用 ip 地址时(因为这是一个共享服务器)，我找不到我的 php 代码，因为我不知道如何链接到我的地址。

有谁...有人知道如何将我链接到我的网站，这样我就可以上传一个 xml 文件吗？这里真的需要帮助......

任何帮助将不胜感激，因为我对网络知识一无所知。

    HttpURLConnection connection = null; 
    DataOutputStream outputStream = null;
    DataInputStream inputStream = null;
    String pathToOurFile = "/data/data/test.send/testsend.txt";
    String urlServer = "http://www.site.com/filefortransfer.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)
    String serverResponseCode = Integer.toString(connection.getResponseCode());
    String serverResponseMessage = connection.getResponseMessage();

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

    }
    catch (Exception ex)
    {
        Log.e("MediaPlayer", "error: " + ex.getMessage(), ex);
    }
    }

在 Android 上，更复杂的 HTTP 网络最好使用 HttpClient 类。

这是一个多部分文件上传的例子:http://rapidandroid.org/wiki/HttpUpload
