使用HTTPBuilder獲取REST API的響應

Question

我試圖調用get方法（HttpGetJson）以返回響應值，並使用它從中獲取resp（用於響應代碼）和json（用於內容）值。 但是只有當我分別從response.success返回resp和json時，我才獲得有效的輸出。 如果我嘗試返回響應對象，我只會得到NULL。 有沒有辦法返回響應。

public static Object HttpGetJson(String url, String path)
        def http = new HTTPBuilder(url)

        //perform a GET request, expecting JSON response
        http.request(GET,JSON) { req ->
            uri.path = path

            //response handler for a success response code
            response.success = { resp, json ->
                return response//using response instead of json or resp returns null
            }
        }

public void testGET()
{

    def url = 'testurl'
    def path = 'testpath'

    //submit a request through GET
    def response1 = HttpUtils.HttpGetJson(url,path)

    println response1
    //println response.statusLine.statusCode
}

Answer 1

您可以同時返回兩者的地圖，例如return [resp: resp, json: json] 。

IMO，您應該傳遞一個閉包，以便從response.success執行：

static HttpGetJson(String url, String path, Closure success) {
    def http = new HTTPBuilder(url)

    //perform a GET request, expecting JSON response
    http.request(GET,JSON) { req ->
        uri.path = path

        //response handler for a success response code
        response.success = success
    }
}

void testGET() {
    def url = 'testurl'
    def path = 'testpath'

    //submit a request through GET
    def response1 = HttpUtils.HttpGetJson(url,path) { resp, json ->
        println resp
        println json
    }

}
