我想使WCF服務可以將圖像放入流中。WCF服務流式圖像
我在配置未來:
<service name="Images" behaviorConfiguration="ImagesBehavior">
<endpoint address="http://localhost:5523/Images.svc"
binding="basicHttpBinding" contract="Images" />
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
<host>
<baseAddresses>
<add baseAddress="http://localhost:5523/Images" />
</baseAddresses>
</host>
</service>
<behavior name="ImagesBehavior">
<serviceDebug includeExceptionDetailInFaults="true" />
<serviceMetadata httpGetEnabled="true" />
</behavior>
和代碼:
[OperationContract]
[WebGet(UriTemplate = "GetImage/{imageID}",
BodyStyle = WebMessageBodyStyle.Bare)]
public Stream GetImage(string imageID)
{
try
{
if (WebOperationContext.Current != null)
WebOperationContext.Current.OutgoingResponse.ContentType = "image/jpeg";
var ms = new MemoryStream(myImage);
return ms;
}
catch (Exception e)
{
if (WebOperationContext.Current != null)
WebOperationContext.Current.OutgoingResponse.ContentType = "text/xml";
Console.WriteLine("GetImage ERROR:" + e.Message + "\r\n" + e.StackTrace);
byte[] errorBytes = Encoding.UTF8.GetBytes("ERROR");
return new MemoryStream(errorBytes);
}
}
但是當我通過瀏覽器嘗試此類似
http://localhost:5523/Images.svc/GetImage/imagecodeblabla
我有
400錯誤的請求
當
http://localhost:5523/Images/GetImage/imagecodeblabla
405不允許的方法
有什麼不對?
如果WebOperationContext.Current爲null,您肯定會得到奇怪的答覆。 – BugFinder
但我甚至沒有進入功能。未達到斷點。 – Ksice
