Question

这给出了一个错误：＆＃34;转义关闭只能捕获...＆＃34;

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：如果要返回状态代码，请使用此回调函数。回调后，您会在收到回复后立即返回状态代码。

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)!)
        }
    }

要打电话，请使用：

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

Alamofire 4，Swift 3：无法返回StatusCode
