Laravel post 文件出现 HTTP::attach 错误：需要“contents”键

Question

我尝试通过 Http 门面发送文件，如文档中所述，我不明白失败的原因，我添加了内容 $stage->pdfFile，我通过 file_get_contents() 获取它，它不是空的，它是文件的数据.

我总是收到错误：需要“内容”键。

public function sendPdfFile($id)
    {

        try {

            $stage = Stage::findOrFail($id);
            $stage->setPdfFileAttribute();

            //test
            //dd($stage->pdfFile);//ok

            $response = Http::attach('pdfFile',$stage->pdfFile,$stage->n_stage.'.pdf')
                ->post($this->endpointFileUploadUrl);


        }catch(\Exception $exception){
            $this->error("error sending file ".$stage->n_stage.".pdf to ".$this->endpointFileUploadUrl.' : '.$exception->getMessage());
        }

    } 

这是有关该内容的文档https://laravel.com/docs/8.x/http-client

$response = Http::attach(
    'attachment', file_get_contents('photo.jpg'), 'photo.jpg'
)->post('http://example.com/attachments');

我就这样改了，同样的错误：

public function sendPdfFile($id)
    {

        try {

            $stage = Stage::findOrFail($id);
            $stage->setPdfFileAttribute();

            //test
            //dd($stage->pdfFile);//ok

            $response = Http::attach('pdfFile',$stage->pdfFile,$stage->n_stage.'.pdf')
                ->post($this->endpointFileUploadUrl, [
'name' => 'pdfFile',
'contents' => $stage->pdfFile,
]);


        }catch(\Exception $exception){
            $this->error("error sending file ".$stage->n_stage.".pdf to ".$this->endpointFileUploadUrl.' : '.$exception->getMessage());
        }

    }

仅对于多部分请求，您应该将数组中的每个参数及其内容作为

post

方法的第二个参数（数组的数组）传递。

$response = Http::attach('pdfFile',$stage->pdfFile,$stage->n_stage.'.pdf')
->post($this->endpointFileUploadUrl, [
                [
                    'name' => 'param 1',
                    'contents' => 'param 1 contents'
                ],
                ....
    ]);

如果有人仍然面临这个问题，请找到适合我的代码。

来自 Laravel 应用程序的请求 1

request = Http::withHeaders(['Accept' => 'Application/Json']);

        foreach ($this->files as $key => $file) {

            $request->attach("file{$key}", fopen($file['file']->getRealPath(), 'r'), $file['filename']);
        }

        $response = $request->post(
            "{$this->url}",
            [
                'firstname' => $this->firstname,
                'lastname' => $this->lastname,
                'phone' => $this->phone,
                'reference' => $this->reference,
                'file_count' => count($this->files)
            ]
        );

Laravel 应用程序 2 中处理传入请求的代码

 $file_count = $request->file_count;

    for($i=0; $i<$file_count; $i++){

        Document::create([
            'name' => $request->file("file{$i}")->getClientOriginalName(),
            'path' => $request->file("file{$i}")->store('documents', 'public'),
        ]);
    }

希望它能帮助别人..

检查此屏幕截图，这对我有用

$data = [
                'name' => $request->get('full_name'),
                'email'  =>$request->get('email')
            ];

我将上面的数组格式更改为下面给出的数组格式，它开始为我工作。

 $data =  [
            [
                'name' => 'full_name',
                'contents' => $request->get('full_name')
            ],  
            [
                'name' => 'email',
                'contents' => $request->get('email')
            ]
        ];
