当我尝试使用 HttpClient 进行DO时，我收到以下错误：

java.lang.ClassCastException: [B cannot be cast to java.lang.String

我的目标： https://portaldecustas.tjsp.jus.br/portaltjsp/

我的GET配置： [expectContinueEnabled = false，proxy = null，localAddress = null，cookie_pec = null，redirectsEnabled = true，relativeRedirectsAllowed = true，maxRedirects = 50，circularRedirectsAllowed = false，authenticationEnabled = true，targetPreferredAuthSchemes = null，proxyPreferredAuthSchemes = null，connectionRequestTimeout = 1000，connectTimeout = 60000，socketTimeout = 60000，contentCompressionEnabled = true]

（我搜索过此错误，但我没有找到针对此特定情况的解决方案）

代码：

HttpGet get = newGetMethod(getTarget(), getTimeoutHandler());
HtmlNode htmlNode = requestHtml(get);

...当newGetMethod它是我公司框架的一种方法时：

/**
 * 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;
}

Answer 1

这是我的.pom文件中的Http客户端版本

我解决了这个问题：

<dependency>
            <groupId>org.apache.httpcomponents</groupId>
            <artifactId>httpclient</artifactId>
            <version>4.3.3</version>
        </dependency>

Answer 2

如果您使用的是httpclient库的版本4.5.3或5.0 Alpha1，则是由于以下错误-https://issues.apache.org/jira/browse/HTTPCLIENT-1836

更新为4.5.4 / 5.0 Alpha2或更高版本。
