Today I'll talk to you about the fact that this method or property is not supported after calling HttpRequest.GetBufferlessInputStream. How to do, many people may not understand, in order to let you better understand, the editor summed up the following content, I hope you can gain something according to this article.

In. Net 4.5, WCF takes advantage of input streams with fewer buffers to achieve scalability. Therefore, when you try to access the HttpContext.Current.Request.InputStream property, you may encounter the following exception because the InputStream property attempts to let you process the Classic stream because none of them are compatible. You may also see another side effect of the HttpContext.Current.Request.Form parameter become null.

"this method or property is not supported after calling HttpRequest.GetBufferlessInputStream."

1. Add a simple HttpModule to the same WCF project that will access the InputStream property of each request before WCF reads it, so that it will force HttpContext.Request.ReadEntityBody to "Classic" and ensure compatibility.

Namespace SKWcfService {public class WcfReadEntityBodyModeWorkaroundModule: IHttpModule {public void Dispose () {} public void Init (HttpApplication context) {context.BeginRequest + = context_BeginRequest;} public void context_BeginRequest (object sender, EventArgs e) {/ / this forces HttpContext.Request.ReadEntityBody to be "Classic" and ensures compatibility. Stream stream = (sender as HttpApplication) .request. InputStream;}

two。

Register this module in web.config by adding the following line to the settings.

If your project cannot be modified, you can write the Http module in a separate assembly, GAC it separately, and register the module in web.config.

Now try to access the service it should be successful!

After reading the above, you do not support this method or property after calling HttpRequest.GetBufferlessInputStream. Do you have any further understanding of what to do?
