在抢先模式下使用groovy http-builder

// Maven<dependency>
 <groupId>org.codehaus.groovy.modules.http-builder</groupId>
 <artifactId>http-builder</artifactId>
 <version>0.7.2</version>
</dependency>

// Gradle
implementation 'org.codehaus.groovy.modules.http-builder:http-builder:0.7.2'

import groovyx.net.http.HTTPBuilder
import static groovyx.net.http.ContentType.JSON
import static groovyx.net.http.Method.GET

def http = new HTTPBuilder('https://api.example.com')

http.request(GET, JSON) { req ->
    uri.path = '/some/endpoint'

    response.success = { resp, json ->
        println "Response status: ${resp.statusLine}"
        println "Content-Type: ${resp.contentType}"
        println "Response data: ${json}"
    }

    response.failure = { resp ->
        println "Request failed with status: ${resp.statusLine}"
    }
}
