net8 webapi

直接用net8 web api模板，創建時不要選控制器，直接添加類文件，並調整基類等即可

在iis上發佈要安裝：dotnet-hosting-8.0.1-win.exe

直接執行exe文件可以發佈，在Windows2019 IIS發佈成功，在Windows10 iis發佈失敗

上傳大於30M的問題，在IIS上發佈時，需要在Web.config中修改：

<system.webServer>中加入：

<security>
      <requestFiltering>
        <requestLimits maxAllowedContentLength="2147483647">        </requestLimits>
      </requestFiltering>
</security>

以上測試調用未加  [DisableRequestSizeLimit]的p3接口上調用成功，但在p4接口上反而失敗。

如果直接用exe發佈web則不需web.config中配置最大值，直接使用   [DisableRequestSizeLimit]
