将 commons-httpclient-3.1.jar 升级到 httpclient-4.5.2.jar

Question

由于一些漏洞，我们需要从 commons-httpclient-3.1.jar 移动到 httpclient-4.5.2.jar

现在有一个之前在 3.1 上工作的代码库，但这些方法在 4.5.2 中已弃用。您对如何克服这些错误有任何想法或遇到过

我得到的错误是 1) 无法解析导入 org.apache.commons.httpclient.HostConfiguration 2) 方法 getState() 对于 HttpClient 类型未定义

这是源代码。如果您有任何信息，请告诉我。
