在Laravel 5.1中处理多个文件(作为API) [英] Processing multiple files in Laravel 5.1 (as an API)
问题描述
所以这似乎是一件很基本的事情，但是我在网上找不到很多有关正在发生的事情的文档....
So this seems like a pretty basic thing but I can't find a lot of documentation online about what's going on....
我正在尝试使用Laravel 5.1浏览文件列表，我只能返回/处理/查看第一个文件.我正在使用Postman将请求发送到API(因此我知道在POST请求中启用了multiple)，然后通过几种不同的方式进行迭代:
I'm trying to run through a list of files using Laravel 5.1 and I can only return/process/see the first file. I'm using Postman to send the request to the API (so I know multiple is enabled in the POST request) and then iterating through that a few different ways:
public function files(Request $request)
{
foreach($request->files as $file)
{
var_dump($file);
}
}
偶:
public function files()
{
foreach($_FILES['files'] as $file)
{
var_dump($file);
}
}
我总是返回(如果使用$request->files方法，则返回对象形式):
I'm always returning (or the object form if the $request->files method is used):
string 'Screen%20Shot%202015-10-23%20at%2010.07.23%20AM.png' (length=51)
string 'image/png' (length=9)
string '/tmp/phpZw1ALu' (length=14)
int 0
int 13687
为什么会这样?如何在Laravel 5.1的控制器中查看多个文件?
Why is this happening? What can I do to see multiple files in Laravel 5.1's controllers?
推荐答案
所以我用下面的代码files.php创建了一个崭新的页面，它现在返回所有三个文件(或者我上传的文件很多):
So I made a brand new page with the following code called files.php and it's now returning all three files (or however many I upload):
<!DOCTYPE>
<html>
<body>
<form method="post" enctype="multipart/form-data" action="http://lucolo.dev/files">
<input type="file" name="files[]" multiple>
<input type="submit" value="Upload">
</form>
</body>
</html>
错误是我在Postman中收到了POST请求，但只接受一个名为files而不是files[]的参数.一旦更改，我的Laravel控制器中的代码:
The error was that I was had the POST request in Postman only accepting a parameter named files instead of files[]. Once that was changed, the code in my Laravel controller:
public function files(Request $request)
{
foreach($request->files as $file)
{
var_dump($file);
}
}
现在返回:
array (size=3)
0 =>
object(Symfony\Component\HttpFoundation\File\UploadedFile)[84]
private 'test' => boolean false
private 'originalName' => string 'Screen Shot 2015-10-23 at 10.07.23 AM.png' (length=41)
private 'mimeType' => string 'image/png' (length=9)
private 'size' => int 270504
private 'error' => int 0
private 'pathName' (SplFileInfo) => string '/tmp/php1M5ZJl' (length=14)
private 'fileName' (SplFileInfo) => string 'php1M5ZJl' (length=9)
1 =>
object(Symfony\Component\HttpFoundation\File\UploadedFile)[85]
private 'test' => boolean false
private 'originalName' => string 'Screen Shot 2015-10-26 at 7.28.59 PM.png' (length=40)
private 'mimeType' => string 'image/png' (length=9)
private 'size' => int 13687
private 'error' => int 0
private 'pathName' (SplFileInfo) => string '/tmp/phpE22ubf' (length=14)
private 'fileName' (SplFileInfo) => string 'phpE22ubf' (length=9)
2 =>
object(Symfony\Component\HttpFoundation\File\UploadedFile)[86]
private 'test' => boolean false
private 'originalName' => string 'Screen Shot 2015-10-27 at 2.50.58 PM.png' (length=40)
private 'mimeType' => string 'image/png' (length=9)
private 'size' => int 786350
private 'error' => int 0
private 'pathName' (SplFileInfo) => string '/tmp/phph8v0C8' (length=14)
private 'fileName' (SplFileInfo) => string 'phph8v0C8' (length=9)
