Hyperpoet is a Marcel and Groovy-friendly HTTP client written in Java 8 backed by OkHttp.

The main goal of this library is to be able to perform HTTP requests with as less code as possible. It is

For that, several functionalities were implemented

• Automatic I/O handling : No need to open and close Input/OutputStream, the poet does it for you

• Automatic response body parsing : The poet automatically parse the response's data given its Content-Type header. You can also explicitly specify it yourself.

• Automatic request body composing : The client/poet automatically compose the request's body (if any) given a provided content type.

You can also find features such as

• customize error handling
• handle authentication
• get history of requests/responses
• perform requests using Domain Specific Language
• printing request/responses (on a Linux terminal, useful with groovysh)
