类 AsyncHttpRequestRetryExec

java.lang.Object

org.apache.hc.client5.http.impl.async.AsyncHttpRequestRetryExec

所有已实现的接口:

AsyncExecChainHandler

@Contract(threading=STATELESS)
 @Internal
public final class AsyncHttpRequestRetryExec
extends Object
implements AsyncExecChainHandler

Request executor in the asynchronous request execution chain that is responsible for making a decision whether a request that failed due to an I/O exception or received a specific response from the target server should be re-executed. Note that this exec chain handler will not respect HttpRequestRetryStrategy.getRetryInterval(HttpResponse, int, org.apache.hc.core5.http.protocol.HttpContext).

Further responsibilities such as communication with the opposite endpoint is delegated to the next executor in the request execution chain.

If this handler is active, pay particular attention to the placement of other handlers within the handler chain relative to the retry handler. Use ChainElement.RETRY as name when referring to this handler.

If a custom handler is placed before the retry handler, the handler will see the initial request and the final outcome after the last retry. Elapsed time will account for any delays imposed by the retry handler.

A custom handler which is placed after the retry handler will be invoked for each individual retry. Elapsed time will measure each individual http request, without the delay imposed by the retry handler.

从接口复制的说明: AsyncExecChainHandler

Executes the actual HTTP request. The handler can choose to return a response message immediately inside the call or asynchronously at some later point or delegate request execution to the next element in the execution chain.

指定者:

execute 在接口中 AsyncExecChainHandler

参数:

request - the actual request.

entityProducer - the request entity producer or null if the request does not enclose an entity.

scope - the execution scope .

chain - the next element in the request execution chain.

asyncExecCallback - the execution callback.

抛出:

HttpException

IOException
