cefsharp获取ajax返回值,使用CEfSharp之旅（6）攔截網絡請求 截取response返回
主要是繼承實現 Cefsharp的IRquestHandler對象,
廢話不多說上代碼：
public class request : IRequestHandler
{
public event Action msg;
public event Action msg2;
public bool GetAuthCredentials(IWebBrowser browserControl, IBrowser browser, IFrame frame, bool isProxy,
string host, int port, string realm, string scheme, IAuthCallback callback)
{
return false;
}
public IResponseFilter GetResourceResponseFilter(IWebBrowser browserControl, IBrowser browser, IFrame frame, IRequest request, IResponse response)
{
//if (!response.ResponseHeaders["Content-Type"].Contains("application/json"))
//{
// return null;
//}
var filter = FilterManager.CreateFilter(request.Identifier.ToString());
return filter;
}
private void Filter_VOIDFUN(string arg1, string arg2, string arg3, long arg4)
{
msg2?.Invoke(arg1, arg2);
}
public bool OnBeforeBrowse(IWebBrowser browserControl, IBrowser browser, IFrame frame, IRequest request,
bool isRedirect)
{
var m = request.Method;
msg?.Invoke(request.Url);
msg?.Invoke(m);
if (request.Method == "POST")
{
using (var postData = request.PostData)
{
if (postData != null)
{
var elements = postData.Elements;
var charSet = request.GetCharSet();
foreach (var element in elements)
{
if (element.Type == PostDataElementType.Bytes)
{
var body = element.GetBody(charSet);
msg?.Invoke(body);
}
}
}
}
}
return false;
}
public CefReturnValue OnBeforeResourceLoad(IWebBrowser browserControl, IBrowser browser, IFrame frame, IRequest request, IRequestCallback callback)
{
var m = request.Method;
msg?.Invoke(request.Url);

{

{

msg?.Invoke(body);
}
}
}
}
}
return CefReturnValue.Continue;
