Question

我正在尝试将文件从模拟器上传到php服务器。虽然logcat或http错误日志没有任何问题，但我没有看到该文件应该在哪里。服务器以HTTP_OK响应。这是上传功能

public void uploadPic() {
    ThreadPolicy tp = ThreadPolicy.LAX;
    StrictMode.setThreadPolicy(tp);

    Log.e("@@@@@@@@@", "Uploadpic called");
    HttpURLConnection connection = null;
    DataOutputStream outputStream = null;
    DataInputStream inputStream = null;

    String pathToOurFile = "/data/icon.jpg";
    String urlServer = "http://192.168.1.9/savepic2.php";
    //String urlServer = "http://winlab.rutgers.edu/~achanda";
    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=\"file\";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)
    //serverResponseCode = connection.getResponseCode();
    Log.e("@@@@@@@", connection.getResponseMessage());

    fileInputStream.close();
    outputStream.flush();
    outputStream.close();
    }
    catch (Exception ex)
    {
        ex.printStackTrace();
    }

}

这是PHP代码

    <?php
if ($_FILES["file"]["error"] > 0)
{
        echo "Error: " . $_FILES["file"]["error"] . "<br />";
}
else
{
        echo "Upload: " . $_FILES["file"]["name"] . "<br />";
        echo "Type: " . $_FILES["file"]["type"] . "<br />";
        echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
        echo "Stored in: " . $_FILES["file"]["tmp_name"]. "<br />";

        $target_path = "uploads/";

        $target_path = $target_path . basename( $_FILES["file"]["name"]);

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

这里还有什么问题？

经过一些测试后，我相信您的问题是以清单中的权限进行的以及模拟器或设备上不存在的文件......

我将以下代码上传到我的测试服务器，我用吐司输出错误＆amp;一个textview显示成功的结果。
