Laravel 7 HTTP 客户端附加多个文件

使用Laravel 7的HTTP客户端可以轻松地与外部API进行交互。在某些情况下，我们可能需要向API上传多个文件。本文将介绍如何使用Laravel 7的HTTP客户端来实现这一功能，并提供相应的案例代码。

php
Route::get('/upload', 'UploadController@uploadForm');
Route::post('/upload', 'UploadController@uploadFiles');

bash
php artisan make:controller UploadController

php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class UploadController extends Controller
{
    public function uploadForm()
    {
        return view('upload');
    }
    public function uploadFiles(Request $request)
    {
        $files = $request->file('files');
        foreach ($files as $file) {
            // 处理文件上传逻辑
        }
        return response()->json(['message' => 'Files uploaded successfully']);
    }
}

html
    @csrf
    
    上传文件

php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Http;
class UploadController extends Controller
{
    public function uploadForm()
    {
        return view('upload');
    }
    public function uploadFiles(Request $request)
    {
        $files = $request->file('files');
        foreach ($files as $file) {
            $response = Http::attach(
                'file',
                file_get_contents($file),
                $file->getClientOriginalName()
            )->post('http://api.example.com/upload');
            // 处理API响应
        }
        return response()->json(['message' => 'Files uploaded successfully']);
    }
}
