定義

多載

AddPolicyHandler(IHttpClientBuilder, IAsyncPolicy<HttpResponseMessage>)

新增 PolicyHttpMessageHandler,其會將提供的 IAsyncPolicy`1 以要求執行括住。

AddPolicyHandler(IHttpClientBuilder, Func<IServiceProvider,HttpRequestMessage,IAsyncPolicy<HttpResponseMessage>>)

新增會以 policySelector 所傳回原則括住要求執行的 PolicyHttpMessageHandler

AddPolicyHandler(IHttpClientBuilder, Func<HttpRequestMessage,IAsyncPolicy<HttpResponseMessage>>)

新增會以 policySelector 所傳回原則括住要求執行的 PolicyHttpMessageHandler

AddPolicyHandler(IHttpClientBuilder, Func<IServiceProvider,HttpRequestMessage, String,IAsyncPolicy<HttpResponseMessage>>, Func<HttpRequestMessage, String>)

加入, PolicyHttpMessageHandler 其會使用藉由執行提供的索引鍵選取邏輯 keySelectorpolicyFactory所傳回的原則來括住要求執行。

AddPolicyHandler(IHttpClientBuilder, IAsyncPolicy<HttpResponseMessage>)

新增 PolicyHttpMessageHandler,其會將提供的 IAsyncPolicy`1 以要求執行括住。

適用於

AddPolicyHandler(IHttpClientBuilder, Func<IServiceProvider,HttpRequestMessage, String,IAsyncPolicy<HttpResponseMessage>>, Func<HttpRequestMessage, String>)

加入, PolicyHttpMessageHandler 其會使用藉由執行提供的索引鍵選取邏輯 keySelectorpolicyFactory所傳回的原則來括住要求執行。

public:
[System::Runtime::CompilerServices::Extension]
 static Microsoft::Extensions::DependencyInjection::IHttpClientBuilder ^ AddPolicyHandler(Microsoft::Extensions::DependencyInjection::IHttpClientBuilder ^ builder, Func<IServiceProvider ^, System::Net::Http::HttpRequestMessage ^, System::String ^, Polly::IAsyncPolicy<System::Net::Http::HttpResponseMessage ^> ^> ^ policyFactory, Func<System::Net::Http::HttpRequestMessage ^, System::String ^> ^ keySelector);

<Extension()>
Public Function AddPolicyHandler (builder As IHttpClientBuilder, policyFactory As Func(Of IServiceProvider, HttpRequestMessage, String, IAsyncPolicy(Of HttpResponseMessage)), keySelector As Func(Of HttpRequestMessage, String)) As IHttpClientBuilder

參數

policyFactory
Func<IServiceProvider,HttpRequestMessage,String,IAsyncPolicy<HttpResponseMessage>>

根據索引鍵選取項目,選取要套用至目前要求的 IAsyncPolicy`1

keySelector
Func<HttpRequestMessage,String>

用於根據 HttpRequestMessage 產生原則索引鍵的委派。

傳回

可以用於設定用戶端的 IHttpClientBuilder

備註

所產生的 policyFactory 索引鍵會先用來查閱 IPolicyRegistry 中的現有原則。 如果登錄中沒有原則,請使用 建立新的原則 policyFactory ,並在 IPolicyRegistry 中新增原則。

如需設定原則的指引,請參閱的 PolicyHttpMessageHandler 備註。
