The POST request will have some content with it. Decoding this data is simple; we just call the DecodeData() method on the request object. The Content-Type HTTP header determines which decoder will be used when decoding the payload. We will assume plain text will be sent (Content-Type equal to text/plain).

if (!req.HasData) 
   throw new BadRequestException(); 
                                  
string s = req.DecodeData() as string;

You can easily create your own content decoders. This is done by creating a class with a default constructor, implementing the Waher.Content.IContentDecoder interface, and making sure the assembly is initialized in the runtime inventory.

We then use the static Waher.Content.CommonTypes to ...
