c# – HTTP错误404.13 – asp.net core 2.0

HTTP Error 404.13 – Not Found The request filtering module is
configured to deny a request that exceeds the request content length.

Verify the
configuration/system.webServer/security/requestfiltering/requestLimits@maxAllowedContentLength
setting in the applicationhost.config or web.config file.

我不知道我在哪里可以配置,在asp.net核心2中有改变使用appsettings.json而不是.

甚至尝试这样做,但它不起作用.

services.Configure<FormOptions>(options =>
{
    options.MultipartBodyLengthLimit = 300_000_000;
});

解决方法

如果您使用IIS,则需要在asp.net core 2.0 app中添加web.config.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.webServer>
    <security>
      <requestfiltering>
        <!-- This will handle requests up to 700MB (CD700) -->
        <requestLimits maxAllowedContentLength="737280000" />
      </requestfiltering>
    </security>
  </system.webServer>
</configuration>

如果您不使用IIS,则可以在控制器中使用[RequestSizeLimit(long.MaxValue)]或[disableRequestSizeLimit]属性.

此外,您可以在Program.cs中添加全局设置：

.UseKestrel(o => { o.Limits.MaxRequestBodySize = null; })
