Hi

I want to connect to internet via proxy. Checked on Win11. UPP build 17953.
Code I am using. Compiled with Core and Core/SSL packages.

#include <Core/Core.h>

using namespace Upp;

CONSOLE_APP_MAIN {
	HttpRequest http(
		"https://restcountries.com/v3.1/name/germany?fullText=true&fields=name,capital");
		http.SSLProxy("http://192.168.1.1",3128);
		http.SSLProxyAuth("username","password");
		http.Trace(true);
	auto content = http.Method(HttpRequest::METHOD_GET).Execute();
	if(content.IsVoid()) {
		Cout() << "Failed to execute GET request with error code " << http.GetStatusCode()
			   << ".\n";
		return;
	}
	DUMP(content);
}

With Trace on log

HTTP START
Using proxy http://192.168.1.1:3128
Starting status 2 'Resolving host name', url: restcountries.com
HTTP Execute: Resolving host name
HTTP StartConnect
HTTP retry on error connect: not found
Starting status 1 'Start', url: restcountries.com
HTTP Execute: Start
HTTP START
Using proxy http://192.168.1.1:3128
Starting status 2 'Resolving host name', url: restcountries.com
HTTP Execute: Resolving host name
HTTP StartConnect
HTTP retry on error connect: not found

Request help

Warm Regards

Deepak

Hello Deepak.

The SSL header is missing. You need to add it too.
I tested it with tinyproxy/localhost and it works fine:

#include <Core/Core.h>
#include <Core/SSL/SSL.h> // <==

using namespace Upp;

CONSOLE_APP_MAIN {
	HttpRequest http(
		"https://restcountries.com/v3.1/name/germany?fullText=true&fields=name,capital");
		http.SSLProxy("localhost",8888);
		http.SSLProxyAuth("username","password");
		http.Trace(true);
	auto content = http.Method(HttpRequest::METHOD_GET).Execute();
	if(content.IsVoid()) {
		Cout() << "Failed to execute GET request with error code " << http.GetStatusCode()
			   << ".\n";
		return;
	}
	DUMP(content);
}

Best regards,

Hi Oblivion,

Thank you for your response.

After adding

#include <Core/SSL/SSL.h> // <==

I get same error.

I am using squid proxy.

With browser set to use proxy is accessing the url with same username and password.

Any other hints.

Code Section from http.cpp

void HttpRequest::StartConnect()
{
	LLOG("HTTP StartConnect");
	if(!Connect(addrinfo))
		return;
	addrinfo.Clear();

	if(ssl && ssl_proxy_host.GetCount() && !ssl_get_proxy) {
		StartPhase(SSLPROXYREQUEST);
		waitevents = WAIT_WRITE;
		String host_port = host;
		if(port)
			host_port << ':' << port;
		else
			host_port << ":443";
		data << "CONNECT " << host_port << " HTTP/1.1\r\n"
		     << "Host: " << host_port << "\r\n";
		if(!IsNull(ssl_proxy_username))
			data << "Proxy-Authorization: Basic "
			        << Base64Encode(proxy_username + ':' + proxy_password) << "\r\n";
		data << "\r\n";
		count = 0;
		LLOG("HTTPS proxy request:\n" << data);
	}
	else
		AfterConnect();
}

I get HTTP StartConnect in log file

I am not getting HTTPS proxy request: in log file

Warm Regards

Deepak

It is little strange but working

I added just to check with giving both Proxy and SSLProxy parameters. It is working only when both are assigned.

#include <Core/Core.h>
#include <Core/SSL/SSL.h>

using namespace Upp;

CONSOLE_APP_MAIN {
	HttpRequest http(
		"https://restcountries.com/v3.1/name/germany?fullText=true&fields=name,capital");
		http.SSLProxy("http://192.168.1.1",3128);
		http.SSLProxyAuth("username","password");
		http.Proxy("http://192.168.1.1",3128);   <<<===
		http.ProxyAuth("username","password");   <<<===
		http.Trace(true);
	auto content = http.Method(HttpRequest::METHOD_GET).Execute();
	if(content.IsVoid()) {
		Cout() << "Failed to execute GET request with error code " << http.GetStatusCode()
			   << ".\n";
		return;
	}
	DUMP(content);
}

Warm Regards

Deepak
