Abp如何严格限制文件大小

Question

我正在尝试使用过滤器严格设置文件大小限制，与此同时，Startup.cs[=23= 已经有一个默认的全局设置]

Startup.cs

int sizeLimit = 200000;

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

services.Configure<KestrelServerOptions>(options =>
{
    options.Limits.MaxRequestBodySize = sizeLimit;
});

services.Configure<FormOptions>(x => x.MultipartBodyLengthLimit = sizeLimit);

TestApiController.cs 或服务（动态控制器）

[Route("[controller]")]
public class TestApiController : Controller
{
    [HttpPost]
    [RequestSizeLimit(100_000)]
    [RequestFormLimits(MultipartBodyLengthLimit = 100_000)]
    public bool Post(IFormFile file)
    {
        return true;
    }
}

我在上传文件时发现警告日志

A request body size limit could not be applied. The IHttpRequestBodySizeFeature for the server is read-only.

我好像需要把IHttpMaxRequestBodySizeFeatureIsReadOnly设为false，但是不行。 IsReadOnly 中没有 setter。

app.Run(async (context) =>
{
    var httpMaxRequestBodySizeFeature = context.Features.Get<IHttpMaxRequestBodySizeFeature>();
    httpMaxRequestBodySizeFeature.IsReadOnly = false;
});

然后我发现它会受到IsUpgraded的影响，如果调用IHttpUpgradeFeature.UpgradeAsync会将IsUpgraded设置为true。我想知道这个方法可能在某个地方调用过，但我想不通。

bool IHttpMaxRequestBodySizeFeature.IsReadOnly => HasStartedConsumingRequestBody || IsUpgraded;

ref IHttpUpgradeFeature.UpgradeAsync()

需要使用自定义属性 https://github.com/abpframework/abp/issues/12336
