如何设置.Net WebClient :: UploadString（）的内容类型？

Question

I am using .net in C++.

How to set http header content-type if using .Net WebClient::UploadString() or WebClient::UploadData() ?

Basically, I want to send some Unicode string to the HTTP server (using Mongoose), and the server will then decode the data received base on the content-type field. Is there another alternative or any better solution?

Thanks

Answer 1

There is a Headers member as part of the WebClient class. You can set the Content-Type header by adding it to the Headers collection:

myWebClient->Headers->Add("Content-Type","application/x-www-form-urlencoded");

Subsquent calls to UploadString (or other methods that make requests) the header will be sent along with the request.

Answer 2

Call WebClient::GetWebRequest() —it returns an HttpWebRequest object with a ContentType property. You then pass it to WebClient::GetWebResponse() to send the request.
