laravel - 如何将图像从 Laravel Controller 发送到 API Rest

Question

我需要从 Laravel 中的存储中获取图像，并将其从 Controller 发送到外部 API REST。

我正在使用 guzzlehttp multipart，但 API 没有收到文件，返回 file = null

Answer 1

这就是我几天前的做法(从请求中获取文件):

对于单个文件:

public function storeProductImage(Request $request, $id){
    $image = $request->file('image');
    $body = [
              "headers" => [
              "Accept" => "multipart/form-data"
             ],
             "multipart" => [
              "name" => "image",
              "contents" => file_get_contents($image),
              "filename" => $image->getClientOriginalName()
            ]
         ];
    return \GuzzleHttp\Client::request('POST', 'product/'.$id.'/images', $body);
}

对于多个文件:

public function storeProductImage(Request $request, $id){
    $body = [ "headers" => [
                "Accept" => "multipart/form-data"
              ],
              "multipart" => []
           ];
    $images = $request->file('image');
    if (is_array($images)) {
        foreach ($images as $image) {
            array_push($body["multipart"], ["name" => "image[]",
                "contents" => file_get_contents($image),
                "filename" => $image->getClientOriginalName()]);
        }
    }
    return \GuzzleHttp\Client::request('POST', 'product/'.$id.'/images', $body);
}
