在配置IHttpModule的实现类可以通过:
HttpRequest:
得到HTTP请求的正文信息:
request.InputStream.Position = 0;//设置流的位置
StreamReader reader = new StreamReader(request.InputStream);//request请求流 string aa = reader.ReadToEnd(); request.InputStream.Seek(0, SeekOrigin.End);//还原到原来的位置得到请求的头部信息:
HttpRequest request = m_application.Context.Request;
string head = string.Empty;
for (int i = 0; i < request.Headers.Count; i++) { head += request.Headers.GetKey(i) + ":" + request.Headers[i]+"\n"; }HttpResponse的response.OutputStream流不能读只能写,但其提供了一个过滤器要使用前需要声明:
HttpApplication application = sender as HttpApplication;
string[] temp = application.Request.CurrentExecutionFilePath.Split('.');//虚拟路径 if (temp.Length > 0) { application.Response.Filter = new RawFilter(application.Response.Filter); RawFilter filter = (RawFilter)application.Response.Filter; filter.OnRawDataRecordedEvent += new EventHandler(filter_OnRawDataRecordedEvent); }public class RawDataEventArgs : EventArgs
{ private string sourceCode; public RawDataEventArgs(string SourceCode) { this.sourceCode = SourceCode; }public string SourceCode
{ get { return sourceCode; } set { sourceCode = value; } } }//自定义过滤器
public class RawFilter : Stream { Stream responseStream; long position; StringBuilder responseHtml;/*当原始数据采集成功后激发*/
public event EventHandler OnRawDataRecordedEvent;public RawFilter(Stream inputStream)
{ responseStream = inputStream; responseHtml = new StringBuilder(); } public override bool CanRead { get { return true; } }public override bool CanSeek
{ get { return true; } }public override bool CanWrite
{ get { return true; } }public override void Flush()
{ responseStream.Flush(); }public override long Length
{ get { return 0; } }public override long Position
{ get { return position; } set { position = value; } }public override int Read(byte[] buffer, int offset, int count)
{ return responseStream.Read(buffer, offset, count); }public override long Seek(long offset, SeekOrigin origin)
{ return responseStream.Seek(offset, origin); }public override void SetLength(long value)
{ responseStream.SetLength(value); } /*关键的点，在HttpResponse 输入内容的时候，一定会调用此方法输入数据，所以要在此方法内截获数据，经测试能获取webservice时的xml*/ public override void Write(byte[] buffer, int offset, int count) { string aa = System.Text.UTF8Encoding.UTF8.GetString(buffer);responseStream.Write(buffer, offset, count);
} }
