Android - 通过PHP上传图片无法正常工作

我正在尝试使用我在网上发现的几个来源将图像上传到我的服务器。我一直试图用几种方法做到这一点,但是它们似乎都不起作用。从本质上讲,我有一个我想从我的设备上传到服务器的图像。连接成功,服务器上的PHP文件似乎正在响应。这是我的代码进行上传。请注意,这是在AsyncTask中包装的:

ANDROID:

 FileInputStream fileInputStream = new FileInputStream(imgFile);
                    URL url = new URL("xxx/UPLOAD_IMG.php");
                    // Open a HTTP  connection to  the URL
                    conn = (HttpURLConnection) url.openConnection();
                    conn.setDoInput(true); // Allow Inputs
                    conn.setDoOutput(true); // Allow Outputs
                    conn.setUseCaches(false); // Don't use a Cached Copy
                    conn.setRequestMethod("POST");
                    conn.setRequestProperty("Connection", "Keep-Alive");
                    conn.setRequestProperty("ENCTYPE", "multipart/form-data");
                    conn.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);
                    conn.setRequestProperty("uploaded_file", fileName);

                    dos = new DataOutputStream(conn.getOutputStream());
                    dos.writeBytes(twoHyphens + boundary + lineEnd);
                    dos.writeBytes("Content-Disposition: form-data; name=\"uploaded_file\";filename=\""
                            + fileName + "\"" + lineEnd);

                    dos.writeBytes(lineEnd);

                    // create a buffer of  maximum size
                    bytesAvailable = fileInputStream.available();

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

                    // read file and write it into form...
                    bytesRead = fileInputStream.read(buffer, 0, bufferSize);

                    while (bytesRead > 0) {

                        dos.write(buffer, 0, bufferSize);
                        bytesAvailable = fileInputStream.available();
                        bufferSize = Math.min(bytesAvailable, maxBufferSize);
                        bytesRead = fileInputStream.read(buffer, 0, bufferSize);

                    }

                    // send multipart form data necesssary after file data...
                    dos.writeBytes(lineEnd);
                    dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);

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

                    Log.i("uploadFile", "HTTP Response is : "
                            + serverResponseMessage + ": " + serverResponseCode);
                    Log.i("A", "");

                    if (serverResponseCode == 200) {
                        // SUCCESS
                    }

                    //close the streams //
                    fileInputStream.close();
                    dos.flush();
                    dos.close();

和服务器上的PHP:

<?php

$file_path = "/images";

$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';
}
?>

我已将服务器上的文件夹权限设置为:777以尝试解决问题。但这并没有解决任何问题。我还尝试将Image直接存储在数据库中作为BLOB,但这导致数据的加载时间更长。可能是PHP路径不正确吗?我是否必须以不同方式设置路径?

我在这里做错了什么?这有什么替代方案?答案对很多人都有好处,因为我发现很多人都遇到过类似的问题。

编辑:我已将整个代码更改为新内容。但它仍然不起作用。
