abpvnext配置上传文件大小

如果不做任何限制，在前端应用vue实现上传文件时，比如大于100M时就会出现请求文件过大的问题，解决方法可试如下。

在发布的文件的webconfig中配置请求大小

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location path="." inheritInChildApplications="false">
    <system.webServer>
    <security>
      <requestFiltering>
        <requestLimits maxAllowedContentLength="1073741824" />
      </requestFiltering>
    </security>
      <handlers>
        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
      </handlers>
      <aspNetCore requestTimeout="00:20:00" processPath="dotnet" arguments=".\Win.Test.HttpApi.Host.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="OutOfProcess" />
    </system.webServer>
  </location>
</configuration>

复制这一段代码

 <security>
      <requestFiltering>
        <requestLimits maxAllowedContentLength="1073741824" />
      </requestFiltering>
    </security>

在abpvnext的HostModule中设置如下代码：

private void ConfigureBodyLengthLimit(ServiceConfigurationContext context)
        {
            context.Services.Configure<FormOptions>(options =>
            {
                options.ValueLengthLimit = int.MaxValue;
                options.MultipartBodyLengthLimit = int.MaxValue;

                options.MultipartHeadersLengthLimit = int.MaxValue;


            });
        }

然后进行注册

 public override void ConfigureServices(ServiceConfigurationContext context)
        {
            var configuration = context.Services.GetConfiguration();
            var hostingEnvironment = context.Services.GetHostingEnvironment();

            ConfigureBundles();
            ConfigureUrls(configuration);
            ConfigureConventionalControllers();
            ConfigureAuthentication(context, configuration);
            ConfigureLocalization();
            ConfigureVirtualFileSystem(context);
            ConfigureCors(context, configuration);
            ConfigureSwaggerServices(context, configuration);
            ConfigureJson(context);
            ConfigurePasswordSet(context);
            //注册BOLB容器
            ConfigureBLOBServices(configuration);
            //文件上传大小限制
            ConfigureBodyLengthLimit(context);
        }
