我正在通过以下方式捕获v-bind: placeholder：
JSON要使用捕获过滤器，我要做的事情：
public IResponseFilter GetResourceResponseFilter(IWebBrowser browserControl, IBrowser browser, IFrame frame, IRequest request, IResponse response)
{
if (request.Url.ToLower().Contains("myurl") )
{
return Filters.CreateFilter(request.Identifier.ToString());
}
return null;
}
我的 public void OnResourceLoadComplete(IWebBrowser browserControl, IBrowser browser, IFrame frame, IRequest request, IResponse response, UrlRequestStatus status, long receivedContentLength)
{
if (request.Url.ToLower().Contains("myurl"))
{
if (Filters.GetFilter(request.Identifier.ToString()) is JsonFilter filter)
{
//Do something and remove filter...
Filters.DeleteFilter(request.Identifier.ToString());
}
}
}
实现是：
IResponseFilter以上内容适用于class Filters
{
private static ConcurrentDictionary<string, IResponseFilter> dataList = new ConcurrentDictionary<string, IResponseFilter>();
public static IResponseFilter CreateFilter(string guid)
{
var filter = new JsonFilter();
dataList.TryAdd(guid, filter);
return filter;
}
public static IResponseFilter GetFilter(string guid)
{
return dataList[guid];
}
public static void DeleteFilter(string guid)
{
dataList.TryRemove(guid, out IResponseFilter filter);
}
}
internal class JsonFilter : IResponseFilter
{
public List<byte> DataAll = new List<byte>();
public FilterStatus Filter(Stream dataIn, out long dataInRead, Stream dataOut, out long dataOutWritten)
{
try
{
if (dataIn == null || dataIn.Length == 0)
{
dataInRead = 0;
dataOutWritten = 0;
return FilterStatus.Done;
}
dataInRead = dataIn.Length;
dataOutWritten = Math.Min(dataInRead, dataOut.Length);
dataIn.CopyTo(dataOut);
dataIn.Seek(0, SeekOrigin.Begin);
byte[] bs = new byte[dataIn.Length];
dataIn.Read(bs, 0, bs.Length);
DataAll.AddRange(bs);
dataInRead = dataIn.Length;
dataOutWritten = dataIn.Length;
return FilterStatus.NeedMoreData;
}
catch
{
dataInRead = dataIn.Length;
dataOutWritten = dataIn.Length;
return FilterStatus.Done;
}
}
public bool InitFilter()
{
return true;
}
public void Dispose()
{ }
}
的旧版本。但是，现在我在cefSharp上遇到了异常，因为在字典中找不到过滤器。
在较新的版本中发生了更改，还是我的实现不够可靠？
