swift - Alamofire 之后解析 JSON

Question

解析 JSON feed 时遇到困难:

These variations of the electrical characteristics are processed in the electronic circuits and in turn displayed, for a short period, as temperature readings. Thereafter the display will automatically turn off or go into standby mode. This is a reusable device.";

}

我需要提取“brandName”、“companyName”、“versionModelName”等关键元素。我很难找到正确的语法来从 JSON 字典中提取数据元素。

                        Alamofire.request(criteria).validate().responseJSON { responseJSON in
                            print(responseJSON.request)  // original URL request
                            print(responseJSON.response) // HTTP URL response
                            print(responseJSON.data)     // server data
                            print(responseJSON.result)   // result of response serialization

                            if((responseJSON.value) != nil) {
                                if let json = responseJSON.result.value as? [String:Any]{
                                    print(json)
                                    let dataArray = json["gudid"] as? [[String:Any]]
                                    print("JSON: \(dataArray)") // serialized json response

                                }


                            }

                        }

每当我引用 json["gudid"] 时都会收到错误。

有什么例子或建议吗？

我相信您的 json 格式错误，因此您无法解析它。请在这里测试一下: https://jsonlint.com/

编辑:

我认为它格式错误的原因是您必须将所有等号 (=) 替换为冒号 (:)。这是标准的 json 格式。
