java - 调度失败，代理需要身份验证 : Remotely Closed Connection

Question

当我使用调度发出 GET 请求时会发生什么？我可以使用代理，但无法使用需要身份验证的代理。

这有效:

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:

Answer 1

val svc = request.setProxyServer(ps).as_!(user, pass)

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) 

reference

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)
