How to use HTTPBuilder behind a proxy with authentication

问题

I tried 2 hours and could not make it work. This is what I did:

grails add-proxy myproxy "--host=<host>" "--port=<port>" "--username=<username>" "--password=<psw>"
grails use-proxy myproxy

I got connection refused error which mean the proxy is not working

In my groovy file, I add the proxy

def http = new HTTPBuilder("http://http://headers.jsontest.com/")
http.setProxy(host, port, "http");
http.request(Method.GET, JSON) {
    uri.path = '/'
    response.success = { resp, json ->
                    .....
    }
}

I then get groovyx.net.http.HttpResponseException: Proxy Authentication Required

I could not figure out how I set the user/psw for the proxy to make it work

I tried the java way, not working

    System.setProperty("http.proxyUser", username);
    System.setProperty("http.proxyPassword", password);

and

    Authenticator.setDefault(new Authenticator() {
        protected PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication(username, .toCharArray());
    }});

Does anyone know how to do this?

Don't know if it will work, but there's some code over here that shows you should do:

import groovyx.net.http.*
import static groovyx.net.http.ContentType.*
import static groovyx.net.http.Method.*
import org.apache.http.auth.*

def http = new HTTPBuilder( 'http://www.ipchicken.com'  )

http.client.getCredentialsProvider().setCredentials(
    new AuthScope("myproxy.com", 8080),
    new UsernamePasswordCredentials("proxy-username", "proxy-password")
)

http.setProxy('myproxy.com', 8080, 'http')

http.request( GET, TEXT ){ req ->
    response.success = { resp, reader ->
        println "Response: ${reader.text}"
    }
}

回答2:

Proxy authentication uses different HTTP header (https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Proxy-Authorization), so simply adding the header should work for you.

String basicAuthCredentials = Base64.getEncoder().encodeToString(String.format("%s:%s", username,password).getBytes());
http.setHeaders(['Proxy-Authorization' : "Basic " + basicAuthCredentials])
