我将Internet Explorer配置为使用本地PAC文件:
它运作得很好。但是,当我尝试拨打InternetGetProxyInfo()
时,它会以ERROR_CAN_NOT_COMPLETE
失败。可能是什么问题?

SetLastError(0);

dw = GetLastError();
return 0;
}
请不要告诉我使用其他API,这是一个教育性的,不实用的问题。
答案 0 :(得分:2)
有两种方式:
easy:使用虚拟网址调用InternetOpenUrl()
,让wininet
初始化jsproxy:
#define URL "https://yandex.ru:777"
#define HOST "yandex.ru"
HINTERNET hInternet = InternetOpen(_T("try-wininet"), INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, 0);
HINTERNET hUrl = InternetOpenUrl(hInternet, _T("http://0.0.0.0"), NULL, 0, 0, 20);
InternetCloseHandle(hUrl);
InternetCloseHandle(hInternet);
InternetGetProxyInfo(URL,sizeof(URL)-1,HOST,sizeof(HOST)-1, &str, &nb);
GlobalFree(str);
很难:在jsproxy中调用InternetInitializeAutoProxyDll()
。但是要准备参数,您必须自己做所有事情:从注册表中读取设置,解析它们,检测并下载PAC文件,并提供包含AutoProxyHelperVtbl
等功能的GetIPAddress()
实现, IsInNet()
等。
InternetGetProxyInfo()
失败,尽管在对话框的底部设置了一些代理服务器。在这种情况下,您应该致电InternetQueryOption(NULL, INTERNET_OPTION_PROXY,...)
