GetAuthCredentials not been invoked

[chptx]

platform: windows 7, VS2013
cef version: 2623 from cefbuilds.com

hello,

i have modify cefsimple project, add GetAuthCredentials method to SimpleHandler, which inherit from CefRequestHandler, then debug with:
cefsimple.exe --url=http://sample.com --proxy-server=https://myproxy.com –-remote-debugging-port=9999

and i use chrome devtool connect to localhost:9999, i can see that my proxy server has already response with header 'proxy-authenticate: Basic realm="SPDY Proxy"'
but GetAuthCredentials not been inovked at all， where breakpoint has been placed。

is anybody have the same problem as me？

Code: Select all

bool SimpleHandler::GetAuthCredentials(CefRefPtr<CefBrowser> browser, CefRefPtr<CefFrame> frame, bool isProxy,
   const CefString& host, int port, const CefString& realm, const CefString& scheme, CefRefPtr<CefAuthCallback> callback)
{
   if (isProxy) {
      callback->Continue("abcdef", "123456");
      return true;
   }
   return false;
}

Try using a supported version of CEF: https://bitbucket.org/chromiumembedded/ ... -supported

I tested same code on cef_binary_3.2924.1564.g0ba0378_macosx64 today， it has the same problem，with xcode debugging，process not hit the breakpoint at entry of SimpleHandler::GetAuthCredentials.

I have also tested my proxy server with chrome browser(macOS, 56.0.2924.87 64-bit), it works correctly.

Code: Select all

//simple_handler.h
class SimpleHandler : public CefClient,
                      public CefRequestHandler,
                      public CefDisplayHandler,
                      public CefLifeSpanHandler,
                      public CefLoadHandler {
public:
...
virtual bool GetAuthCredentials(
                                       CefRefPtr<CefBrowser> browser,
                                       CefRefPtr<CefFrame> frame,
                                       bool isProxy,
                                       const CefString& host,
                                       int port,
                                       const CefString& realm,
                                       const CefString& scheme,
                                       CefRefPtr<CefAuthCallback> callback) override;
...
}


//simple_handler.cc

bool SimpleHandler::GetAuthCredentials(
                                   CefRefPtr<CefBrowser> browser,
                                   CefRefPtr<CefFrame> frame,
                                   bool isProxy,
                                   const CefString& host,
                                   int port,
                                   const CefString& realm,
                                   const CefString& scheme,
                                   CefRefPtr<CefAuthCallback> callback) {
    if (isProxy) { // <= breakpoint here
        // Provide credentials for the proxy server connection.
        callback->Continue("myuser", "mypass");
        return true;
    }
    return false;
}

and I add parameter "--enable-logging --v=1", it output:

problem is solved, through reading cef source code，I know that it should add these lines to simple_handler.h:

Code: Select all

  virtual CefRefPtr<CefRequestHandler> GetRequestHandler() OVERRIDE {
    return this;
  }

This solution works perfectly with cef_binary_3.3626.1894
