Groovy HttpBuilder - Get Body Of Failed Response

Question

I am trying to use the Groovy HTTPBuilder to write an integration test that will verify a correct error message is returned in the body along with an HTTP 409 status message. Ho

Answer 1

I also struggled with this when I started using HttpBuilder. The solution I came up with was to define the HTTPBuilder success and failure closures to return consistent values like this:

HTTPBuilder http = new HTTPBuilder()
http.handler.failure = { resp, reader ->
    [response:resp, reader:reader]
}
http.handler.success = { resp, reader ->
    [response:resp, reader:reader]
}

Thusly defined, your HTTPBuilder instance will consistently return a map containing a response object (an instance of HttpResponseDecorator) and a reader object. Your request would then look like this:

def map = http.request(ENV_URL, Method.POST, ContentType.TEXT) {
    uri.path = "/curate/${id}/submit"
    contentType = ContentType.JSON
}

def response = map['response']
def reader = map['reader']

assert response.status == 409

The reader will be some kind of object that'll give you access to the response body, the type of which you can determine by calling the getClass() method:

println "reader type: ${reader.getClass()}"

The reader object's type will be determined by the Content-Type header in the response. You can tell the server specifically what you'd like returned by adding an "Accept" header to the request.
