请求正文太大

Question

当我尝试在 Visual Studio 2019 年在 IISExpress 上将一个 80mb 的文件从邮递员上传到我的本地端点运行时，出现以下错误：

The request filtering module is configured to deny a request that exceeds the request content length.

所以我将此添加到项目的 applicationhost.config 中：

<system.web>
      <httpRuntime maxRequestLength="1050000" /> 
    </system.web>
    <system.webServer>
        <security>
            <requestFiltering>
                <requestLimits maxAllowedContentLength="1073741824"/>
            </requestFiltering>
        </security>

当我发出 API 请求时，这阻止了错误的发生，但现在我只得到一个 ServiceStack 生成的“快照”页面，告诉我请求花费了多长时间和日期，但我的实际端点从未被击中。

在我的日志中，我可以看到 ServiceStack 抛出了这个异常：

2020-07-20 01:57:56.0497||ERROR|ServiceStackHost|Request body too large.

所以 Body 长度仍然需要在某处设置，但我看到的每个地方都指向我已经使用过的配置。

是否需要额外的设置或者这是 ServiceStack 的问题？

Answer 1

我在启动时缺少这个选项：


services.Configure<IISServerOptions>(options =>
{
    options.MaxRequestBodySize = int.MaxValue;
});

services.Configure<KestrelServerOptions>(options =>
{
    options.Limits.MaxRequestBodySize = int.MaxValue; // if don't set default value is: 30 MB
});
