Microsoft.AspNetCore.Server.Kestrel.Core.BadHttpRequestException:请求正文太大 [英] Microsoft.AspNetCore.Server.Kestrel.Core.BadHttpRequestException: Request body too large

问题描述

我正在尝试将100MB的影片上传到我的ASP.NET Core应用程序.

I'm trying to upload a 100MB film to my ASP.NET Core application.

我已在操作中设置此属性:

I've set this attribute on my action:

[RequestSizeLimit(1_000_000_000)]

我还更改了Web.config文件，使其包含:

And I also changed my Web.config file to include:

<security>
  <requestFiltering>
    <!-- This will handle requests up to 700MB (CD700) -->
    <requestLimits maxAllowedContentLength="737280000" />
  </requestFiltering>
</security>

换句话说，我已经告诉IIS允许最大700MB的文件，并且我还告诉ASP.NET Core允许接近1GB的文件.

In other words, I've told IIS to allow files up to 700MBs and I've also told ASP.NET Core to allow files of near 1GB.

但我仍然会收到该错误.而且我找不到答案.有什么想法吗?

But I still get that error. And I can't find the answer. Any ideas?

P.S:使用这些配置，我可以传递30MB的默认大小.我可以上传50或70兆字节的文件.

P.S: Using these configurations, I could pass the 30MB default size. I can upload files of 50 or 70 Mega Bytes.

推荐答案

我认为您只需要:[DisableRequestSizeLimit]

I think you just need: [DisableRequestSizeLimit]

下面是一个对我有用的解决方案，用于将Zip文件和其他表单数据上传到运行.Net Core 3的API

below is a solution that worked for me to upload Zip files with additional form data to an API running .Net Core 3

// MultipartBodyLengthLimit  was needed for zip files with form data.
// [DisableRequestSizeLimit] works for the KESTREL server, but not IIS server 
// for IIS: webconfig... <requestLimits maxAllowedContentLength="102428800" />
[RequestFormLimits(ValueLengthLimit = int.MaxValue, MultipartBodyLengthLimit = int.MaxValue)] 
[DisableRequestSizeLimit] 
[Consumes("multipart/form-data")] // for Zip files with form data
[HttpPost("MyCustomRoute")]
public IActionResult UploadZippedFiles([FromForm] MyCustomFormObject formData)
{ }
