十年河东，十年河西，莫欺少年穷

学无止境。，精益求精

1、报错信息如下：

Request URL:
https://xx.com/webapi/api/ad_video/Upload
Request Method:
POST
Status Code:
413 Payload Too Large
Remote Address:
106.15.105.219:443
Referrer Policy:
strict-origin-when-cross-origin

2、解决方案如下：

在web.config 中  <system.webServer> 节下增加如下配置

        <security>
        <requestFiltering>
          <requestLimits maxAllowedContentLength="314572800" />
        </requestFiltering>
      </security>

最大支持上传 300MB

注意：每次发布，都需要重新添加，或者选择不替换 web.config

3、startUp中 ConfigureServices(IServiceCollection services) 增加如下配置

     
            services.Configure<IISServerOptions>(options =>
            {
                options.MaxRequestBodySize = 314572800;  
                
            });
