我们已经尝试了Android和PHP的这个代码.请看下面的代码.
Android的

它返回解析字节串.它的价值太长了.
$base=$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';
以上代码正在运行.但它有一些问题.图像在文件夹中成功保存,但图像将显示为已损坏.我们如何解决这个问题.
提前致谢.
最佳答案
请尝试此代码,此代码适合我.
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);
?>
