Set the request header 'Content-Type' to 'application/json'

[zeroFruit]

I'm using this library to interact with Bitcoin node developed by parity-tech (link). And I have problem to connect parity-bitcoin node because it requires header value 'Content-Type' with 'application/json'.

After testing locally I've found out that this library uses request header 'Content-Type' value as 'application/x-www-form-urlencoded'.

Is this intended behavior? I think it would be better to set 'Content-Type' value as 'application/json' explicitly for supporting parity-bitcoin and following jsonrpc over HTTP header value suggestion
