Question

我试图让我的用户上传.pdf文件，但在调用putFile方法或putFileAs方法时，我收到以下错误：

在null中调用成员函数hashName（） \厂商\ laravel \框架\ SRC \照亮\文件系统\ FilesystemAdapter.php：146

检查putFile方法的$file属性返回null。但是，当我给出给定的参数时，它返回（因为它看起来像）一个普通的文件。

它在whoops中返回以下publication_file

array:5 [▼
  "name" => "users-tragos.pdf"
  "type" => "application/pdf"
  "tmp_name" => "C:\xampp\tmp\phpAB1F.tmp"
  "error" => 0
  "size" => 205603
]

我的控制器代码是：

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Storage;
use Carbon\Carbon;
use App\Http\Controllers\Controller;
use App\publication;
use App\User;

class publicationsController extends Controller
{

public function store(Request $request){
    $this->validate($request, [
    'title' => 'required',
    'author' => 'required',
    'publication_date' => 'required|date_format:m/Y'
    ]);

    if($request->filled("publication_url")){
        $this->validate($request, [
        'publication_url' => 'url'
        ]);

    }
    if($request->filled("publication_file")){
        $this->validate($request, [
        'publication_file' => 'file|mimes:pdf|max:10000'
        ]);
    }

    $publication_date = carbon::createFromFormat('m/Y', request("publication_date"))->format('Y-m-d');


    if($request->hasFile('publication_file')){
        if($request->file('publication_file')->isValid()){
            $path = Storage::putFile('publications', $request->file('publication_file'));
        }
    }
}

我的表单代码是：

<form method="POST" action="/publications" id="form_table" enctype="multipart/form-data">
{{ csrf_field() }}
<table>
<tr><td><label for="title">Title</label></td><td><input type="text" name="title" id="title" required autofocus /></td></tr>
<tr><td><label for="title">Author</label></td><td><input type="text" name="author" id="author" required /></td></tr>
<tr><td><label for="publication_date">Publication Date</label></td><td>
<input type="text" name="publication_date" id="publication_date" required placeholder="mm/yyyy"/></td></tr>
<tr><td colspan="2"><label for="content">Content</label><br /><br />
<textarea name="body" id="content"></textarea></td></tr>
<tr><td><label for="publication_file">Upload .pdf file</label></td><td>
<input type="file" id="publication_file" name="publication_file" accept="application/pdf" /></td></tr>
<tr><td><label for="publication_url">Link to file</label></td><td><input type="text" id="publication_url" name="publication_url" /></td></tr>
<tr><td><button type="submit" value="submit"/>submit</button></td></tr>
</table>
</form>

有谁知道如何解决这个问题？我正在使用Laravel 5.5

Laravel文件上传不起作用。在null
