Java 使用需要身份验证的代理发送失败：远程关闭连接

使用dispatch发出GET请求时发生了什么？我可以使用代理，但不能使用需要身份验证的代理

这项工作：

val ps = new ProxyServer(host, port)
val svc = request.setProxyServer(ps)
val resp = Http(svc > as.String)        

这失败了：

val ps = new ProxyServer(host, port)
val svc = request.setProxyServer(ps).as_!(user, pass)
val resp = Http(svc > as.String)

错误是：

正在为请求设置用户和密码，而不是代理

您应该使用用户和密码信息实例化ProxyServer：

ProxyServer(String host, int port, String principal, String password) 

在您的示例中：

val ps = new ProxyServer(host, port, user, pass)
val svc = request.setProxyServer(ps)
val resp = Http(svc > as.String)

val ps = new ProxyServer(host, port, user, pass)
val svc = request.setProxyServer(ps)
val resp = Http(svc > as.String)
