Class CustomRedirectStrategy

java.lang.Object

org.apache.http.impl.client.DefaultRedirectStrategy

org.apache.http.impl.client.LaxRedirectStrategy

us.codecraft.webmagic.downloader.CustomRedirectStrategy

All Implemented Interfaces:

org.apache.http.client.RedirectStrategy

public class CustomRedirectStrategy
extends org.apache.http.impl.client.LaxRedirectStrategy

支持post 302跳转策略实现类 HttpClient默认跳转：httpClientBuilder.setRedirectStrategy(new LaxRedirectStrategy()); 上述代码在post/redirect/post这种情况下不会传递原有请求的数据信息。所以参考了下SeimiCrawler这个项目的重定向策略。 原代码地址：https://github.com/zhegexiaohuozi/SeimiCrawler/blob/master/project/src/main/java/cn/wanghaomiao/seimi/http/hc/SeimiRedirectStrategy.java
