如何从Laravel控制器发送图像到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未收到文件，返回文件= null

Answer 1

这是我几天前所做的（从Request中获取文件：

对于单个文件：

public function storeProductImage($id, Request $request){
    $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($id, Request $request){
    $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);
}
