当我尝试使用HttpClient执行 DO 时，我收到以下错误：

我的目标是： https://portaldecustas.tjsp.jus.br/portaltjsp/
我的 GET 配置： [expectContinueEnabled=false， proxy=null， localAddress=null， cookieSpec=null， redirectsEnabled=true， relativeRedirectsAllowed=true， maxRedirects=50， circularRedirectsAllowed=false， authenticationEnabled=true， targetPreferredAuthSchemes=null， proxyPreferredAuthSchemes=null， connectionRequestTimeout=1000， connectTimeout=60000， socketTimeout=60000， contentCompressionEnabled=true]
(我已经搜索了这个错误，但我没有找到这个特定案例的解决方案(
它的代码：
HttpGet get = newGetMethod(getTarget(), getTimeoutHandler());
HtmlNode htmlNode = requestHtml(get);
。当newGetMethod是我公司框架中的一种方法：
/**
* Cria um get
*
* @param target Endere?o acessado
* @param timeoutHandler Controla o timeout
* @return Get
* @throws HarvestException Quando ocorre um erro com o tempo a ser usado
*/
public static HttpGet newGetMethod(URI target, TimeoutHandler timeoutHandler) throws HarvestException {
HttpGet method = newGetMethod(target, timeoutHandler.calculate());
method.getParams().setParameter(TIMEOUT_HANDLER_PARAM, timeoutHandler);
return method;
}
这是我的.pom文件中的Http客户端版本
我用这个解决了：
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.3.3</version>
</dependency>
如果您使用的是 httpclient 库的4.5.3或5.0 Alpha1版，这是由于错误 - https://issues.apache.org/jira/browse/HTTPCLIENT-1836
更新到4.5.4/5.0 Alpha2或更高版本。
