AddHttpMessageHandler(IHttpClientBuilder, Func<IServiceProvider,DelegatingHandler>)
添加一个委托，该委托将用于为已命名的 HttpClient 创建附加消息处理程序。
public:
[System::Runtime::CompilerServices::Extension]
static Microsoft::Extensions::DependencyInjection::IHttpClientBuilder ^ AddHttpMessageHandler(Microsoft::Extensions::DependencyInjection::IHttpClientBuilder ^ builder, Func<IServiceProvider ^, System::Net::Http::DelegatingHandler ^> ^ configureHandler);public static Microsoft.Extensions.DependencyInjection.IHttpClientBuilder AddHttpMessageHandler(this Microsoft.Extensions.DependencyInjection.IHttpClientBuilder builder, Func<IServiceProvider,System.Net.Http.DelegatingHandler> configureHandler);static member AddHttpMessageHandler : Microsoft.Extensions.DependencyInjection.IHttpClientBuilder * Func<IServiceProvider, System.Net.Http.DelegatingHandler> -> Microsoft.Extensions.DependencyInjection.IHttpClientBuilder<Extension()>
Public Function AddHttpMessageHandler (builder As IHttpClientBuilder, configureHandler As Func(Of IServiceProvider, DelegatingHandler)) As IHttpClientBuilder参数
- builder
- IHttpClientBuilder
- configureHandler
- Func<IServiceProvider,DelegatingHandler>
用于创建 DelegatingHandler 的委托。
返回
可用于配置客户端的 IHttpClientBuilder。
注解
每次调用委托时，该 configureHandler 委托都应返回消息处理程序的新实例。
提供给 configureHandler 的参数IServiceProvider将是对共享所构造处理程序生存期的作用域服务提供程序的引用。
