用grails接收http状态码

Question

I'm trying to receive status code with url calls.(Using grails)

def http = new HttpResponseDecorator(url)
    // Authentication header
    http.auth.basic(username, password)
    // Http request method. Pulls out json file
    http.request(Method.GET) {
        response.success = {
            render "Success!"
        }
        response.failure = { resp ->;
            render resp
        }
    }

Trying this code snippet to receive make url calls, but I can't figure out how to pull out status code from this.

What I want to do is sending error messages depending on what status code I'm getting.(for example, 400 prints forbidden message of my choice)

Any suggestions for a class to receive status code of the GET calls?

Answer 1

The resp argument to your response.failure closure has a status you can check.

response.failiure = { resp ->
    if (resp.status == 400) {
        // render forbidden message
    }
}

See the Response Handlers section of the httpbuilder docs for more information and examples.
