我下载了 (cefclient & cefsimple) c++ 示例附带的 CEF(chromuim 嵌入式框架)二进制分发版,并意识到 cefclient 可以在运行时更改代理设置.
I downloaded CEF (chromuim embedded framework) binary distributation that comes with (cefclient & cefsimple) c++ examples, And Realized that cefclient can change proxy settings on run-time.
这样做的关键是获取 RequestContext 并调用函数 SetPreference.
And the key to do that is to Grab the RequestContext and call the function SetPreference.
在 CefClient 上一切正常.
on CefClient all works just nice.
但是在 CefSharp 上调用 SetPreference 总是返回 false,并且 HasPreference 也为首选项名称proxy"返回 false.
but on CefSharp calling SetPreference always returns false, and also HasPreference returns false for the preference name "proxy".
推荐答案感谢 amaitland 以正确的方式积极实施更改请求上下文偏好,是在 CEF UIThread 上运行代码如下:
thanks to amaitland the proper way to actively inforce changing the request-context prefrences, is to run the code on CEF UIThread as following:
Cef.UIThreadTaskFactory.StartNew(delegate { var rc = this.browser.GetBrowser().GetHost().RequestContext; var v = new Dictionary<string, object>(); v["mode"] = "fixed_servers"; v["server"] = "scheme://host:port"; string error; bool success = rc.SetPreference("proxy", v, out error); //success=true,error="" });更多推荐
