Alamofire 4、Swift 3：无法返回 StatusCode

Question

这会报错：“转义闭包只能捕获 inout ...”

我该如何解决？

func check_info(tag: String, info: String, code: inout Int) {

    Alamofire.request(
        URL + "/api/test_information/",
        method: .post,
        parameters: [tag: info],
        encoding: JSONEncoding.default
    ).responseString { response in
        code = (response.response?.statusCode)!
    }

}

已编辑：如果要返回状态码，请使用此回调函数。收到响应后，回调会立即返回状态码。

func check_info(tag: String, info: String, statusCode: @escaping (String)->Void){
Alamofire.request(URL + "/api/test_information/", method: .post, parameters: [tag: info], encoding: JSONEncoding.default).responseJSON { response in
            statusCode((response.response?.statusCode)!)
        }
    }

要调用它，请使用：

check_info(tag: "yourtag", info: "yourInfo){
    statusCode in
        print(statusCode)
    }
