问题描述
我们已经尝试了本code为Android和PHP。请参见下面的code。
We have tried this code for android and php. Please see below code.

它返回解析字节字符串。它的值是太长时间。
It returns parsing bytestring. Its value is too much long.
PHP
$base=$Data['images'];
$binary=base64_decode($base);
header('Content-Type: bitmaps; charset=utf-8');
header("Content-Length: " . mb_strlen($base, '8bit'));
$file = fopen('qr_code.jpeg', 'wb');
fwrite($file, $binary);
fclose($file);
echo 'Image upload complete!!, Please check your php file directory';
以上code的工作。但它有一些问题。图片成功保存在文件夹，但为损坏的图像将显示。我们怎样才能解决这个问题。
Above code is working. But it have some issue. Image save successfully in folder but image will be displayed as corrupted. How can we resolve this issue.
在此先感谢。
推荐答案
请试试这个$ C C本code为我工作$。
Please try this code this code working for me.
<?php
// Path to move uploaded files
$target_path = "uploads/";
// array for final json respone
$response = array();
// getting server ip address
$server_ip = gethostbyname(gethostname());
// final file url that is being uploaded
$file_upload_url = 'http://' . $server_ip . '/' . '/xyz/' . '/' . $target_path;
if (isset($_FILES['image']['name'])) {
$target_path = $target_path . basename($_FILES['image']['name']);
// reading other post parameters
$email = isset($_POST['email']) ? $_POST['email'] : '';
$website = isset($_POST['website']) ? $_POST['website'] : '';
$response['file_name'] = basename($_FILES['image']['name']);
$response['email'] = $email;
$response['website'] = $website;
try {
// Throws exception incase file is not being moved
if (!move_uploaded_file($_FILES['image']['tmp_name'], $target_path)) {
// make error flag true
$response['error'] = true;
$response['message'] = 'Could not move the file!';
}
// File successfully uploaded
$response['message'] = 'File uploaded successfully!';
$response['error'] = false;
$response['file_path'] = $file_upload_url . basename($_FILES['image']['name']);
} catch (Exception $e) {
// Exception occurred. Make error flag true
$response['error'] = true;
$response['message'] = $e->getMessage();
}
} else {
// File parameter is missing
$response['error'] = true;
$response['message'] = 'Not received any file!F';
}
// Echo final json response to client
echo json_encode($response);
?>
