Response

ZIO HTTP Response is designed to encode HTTP Response. It supports all HTTP status codes and headers along with custom methods and headers (as defined in RFC2616 )

Creating a Response​

Response can be created with status, headers and data.

The below snippet creates a response with default params, status as Status.OK, headers as Headers.empty and data as Body.Empty.

 val res: Response = Response()

Empty Response​

  • ok creates an empty response with status code 200
 val res: Response = Response.ok
  • status creates an empty response with provided status code.
 val res: Response = Response.status(Status.CONTINUE)

Specialized Response Constructors​

  • text creates a response with data as text, content-type header set to text/plain and status code 200 
 val res: Response = Response.text("hey")
  • json creates a response with data as json, content-type header set to application/json and status code 200 
 val res: Response = Response.json("""{"greetings": "Hello World!"}""")
  • html creates a response with data as html, content-type header set to text/html and status code 200
 val res: Response = Response.html(Html.fromString("html text"))

Specialized Response Operators​

  • setStatus to update the status of Response
val res: Response = Response.text("Hello World!").setStatus(Status.NOT_FOUND)
  • updateHeaders to update the headers of Response
 val res: Response = Response.ok.updateHeaders(_ => Headers("key", "value"))

Response from HttpError​

fromHttpError creates a response with provided HttpError

 val res: Response = Response.fromHttpError(HttpError.BadRequest())

addCookie adds cookies in the headers of the response.

 val cookie = Cookie("key", "value")
 val res = Response.ok.addCookie(cookie)
