我正在嘗試上傳文件。下面的代碼可以在我的本地機器上運行,或者在運行命令行運行dll的遠程服務器上運行,但是當我嘗試發佈到我的測試環境並在iis下運行時,它會失敗。上傳文件ASP核心IIS
<form method="post" asp-action="Upload" asp-controller="Prebook" enctype="multipart/form-data">
<div class="form-inline">
<div class="col-md-2">
<div class="form-group">
<input type="file" name="files" data-input= "false" multiple class="filestyle" data-buttonName="btn-primary">
</div>
</div>
<div class="col-md-2">
<div class="form-group">
<input type="submit" value="Upload File" class="btn btn-primary" />
