Java 在Http Rest客户端中使用代理时发生异常

您好，我正在使用Http Rest客户端登录SalesForce Oauth身份验证。。。。 当我没有代理时，程序运行良好…但是使用Https和代理设置对我不起作用…我的代码是

这甚至可能是由于互联网速度缓慢造成的connection@Nabin有时我确实会收到连接超时错误，这是由于internet连接速度较慢。我收到连接被拒绝的错误。连接被拒绝是否也是由于相同的原因？可能是由于服务器停机。@Nabin认为它与服务器无关，因为我已经尝试了好几天了s now和Salesforce服务器可能会宕机这么长时间。我觉得这是代理的问题。api只支持HTTPS调用。您能确认我在HTTP代码中所做的代理设置也将应用于HTTPS吗？如果不能，如何为HTTPS指定代理？
