错误：413 “请求实体太大” Html + MVC WCF 服务

Question

Basically, I created one page into HTML then i want to send two files XML & SVG. Both files are converted to text and then send to the WCF service in the MVC project. but it gives "Error: 413 “Request Entity Too Large”. I tried a small file & its works. but more than 200kb is not working well. i tried to convert stream, but I had no luck. so I decided to convert it into string & pass it.

My HTML Page -

My WCF code -

also, i checked online solution for that but its already done.

ERROR -

If anyone knows, how to convert string to Stream in javascript, then tell me. I am able to accept stream value.

Answer 1

You can set the Maximum limit for receiving files in WCF like this:

        WebServiceHost webServiceHost = new WebServiceHost(typeof(UploadService), uri);
        WebHttpBinding binding = new WebHttpBinding();
        binding.MaxReceivedMessageSize = Int32.MaxValue;
        webServiceHost.AddServiceEndpoint(typeof(IUploadService), binding, "WebServiceHost");
        webServiceHost.Open();

And you can try setting the upload size limit in HTML web.config.
