我需要一些帮助。我在Ajax中使用FormData发布多个数据，但是在发布第二个和第三个数据后，总是出现500 Internal Server Error。唯一可以发布的文件是第一个数据。
这是我的代码：
HTML文件
addProductModifier(data) {
this.notice.warning(show); // works finf
return this.http.get<any>( api_url + '/addProductModifier', {params: data} ).catch(this.errHandler.bind(this));
}
路线：
<form class="validation-wizard wizard-circle" method="post" data-toggle="validator" enctype="multipart/form-data" id="form">
@csrf
<input type="hidden" id="id" name="id">
