对于使用 Apiato (Laravel) 框架的人：
在下面创建类似文件的新中间件，然后在受保护的 $middlewareGroups 变量（在 web 或 api 中，无论你想要什么）中的 laravel 内核文件中声明这个文件，如下所示：
protected $middlewareGroups = [
'web' => [],
'api' => [HandlePutFormData::class],
];
<?php
namespace App\Ship\Middlewares\Http;
use Closure;
use Symfony\Component\HttpFoundation\ParameterBag;
/**
* @author Quang Pham
*/
class HandlePutFormData
{
/**
* Handle an incoming request.
*
* @param \Illuminate\Http\Request $request
* @param \Closure $next
*
* @return mixed
*/
public function handle($request, Closure $next)
{
if ($request->method() == 'POST' or $request->method() == 'GET') {
return $next($request);
}
if (preg_match('/multipart\/form-data/', $request->headers->get('Content-Type')) or
preg_match('/multipart\/form-data/', $request->headers->get('content-type'))) {
$parameters = $this->decode();
$request->merge($parameters['inputs']);
$request->files->add($parameters['files']);
}
return $next($request);
}
public function decode()
{
$files = [];
$data = [];
// Fetch content and determine boundary
$rawData = file_get_contents('php://input');
$boundary = substr($rawData, 0, strpos($rawData, "\r\n"));
// Fetch and process each part
$parts = $rawData ? array_slice(explode($boundary, $rawData), 1) : [];
foreach ($parts as $part) {
// If this is the last part, break
if ($part == "--\r\n") {
break;
}
// Separate content from headers
$part = ltrim($part, "\r\n");
list($rawHeaders, $content) = explode("\r\n\r\n", $part, 2);
$content = substr($content, 0, strlen($content) - 2);
// Parse the headers list
$rawHeaders = explode("\r\n", $rawHeaders);
$headers = array();
foreach ($rawHeaders as $header) {
list($name, $value) = explode(':', $header);
$headers[strtolower($name)] = ltrim($value, ' ');
}
// Parse the Content-Disposition to get the field name, etc.
if (isset($headers['content-disposition'])) {
$filename = null;
preg_match(
'/^form-data; *name="([^"]+)"(; *filename="([^"]+)")?/',
$headers['content-disposition'],
$matches
);
$fieldName = $matches[1];
$fileName = (isset($matches[3]) ? $matches[3] : null);
// If we have a file, save it. Otherwise, save the data.
if ($fileName !== null) {
$localFileName = tempnam(sys_get_temp_dir(), 'sfy');
file_put_contents($localFileName, $content);
$files = $this->transformData($files, $fieldName, [
'name' => $fileName,
'type' => $headers['content-type'],
'tmp_name' => $localFileName,
'error' => 0,
'size' => filesize($localFileName)
]);
// register a shutdown function to cleanup the temporary file
register_shutdown_function(function () use ($localFileName) {
unlink($localFileName);
});
} else {
$data = $this->transformData($data, $fieldName, $content);
}
}
}
$fields = new ParameterBag($data);
return ["inputs" => $fields->all(), "files" => $files];
}
private function transformData($data, $name, $value)
{
$isArray = strpos($name, '[]');
if ($isArray && (($isArray + 2) == strlen($name))) {
$name = str_replace('[]', '', $name);
$data[$name][]= $value;
} else {
$data[$name] = $value;
}
return $data;
}
}
