我正在使用apache的常见httpclient库.是否可以通过代理发出HTTP请求？更具体地说,我需要使用代理列表来处理多线程POST请求(现在我正在使用单线程GET请求进行测试).

我试着用:

        httpclient.getHostConfiguration().setProxy("67.177.104.230", 58720);

我得到了该代码的错误:

我正在尝试创建通过SOCKS5代理通过Apache HC 4发送HTTP请求的应用程序.我不能使用app-global代理,因为app是多线程的(我需要为每个实例使用不同的代理).我没有找到使用HC4的SOCKS5的例子.我怎么用呢？HttpClient
