php - guzzlehttp 在 Laravel 项目上抛出错误 - strtolower() : Argument #1 ($string) must be of type string, int 给出

Question

我正在尝试在我的 Laravel 项目中使用 guzzlehttp 使用 POST API。但我的开发服务器上出现错误。这在我的本地系统上运行得很好。 $postArray 两边都正确操作。这是我在 Composer 中的 Guzzle 版本:"guzzlehttp/guzzle": "^7.3"。

代码:

     $response = Http::withHeaders([
            "accept: application/json",
            "content-type: application/json"
        ])->post('https://staging.consume.com/testing', $postArray)->json();

错误:

strtolower(): Argument #1 ($string) must be of type string, int given

JSON:

    {
"message": "strtolower(): Argument #1 ($string) must be of type string, int given",
"exception": "TypeError",
