Question

我正在执行alamofire请求，并将主体参数转换为快速字典，但我认为我将其转换为错误的格式。谁能建议我将这个json主体转换为快速参数的正确格式是什么？

我在邮递员中发送的实际尸体给出了正确的答复：-

{
    "events": [
        {
            "distance_to_next_route_change": "null",
            "accelerationX": "0.10055954",
            "accelerationY": "-0.0047885496",
            "accelerationZ": "-0.0047885496",
            "drivingState": "DRIVING",
            "latitude": "12.921918",
            "longitude": "77.658917",
            "next_route_coordinate": "null",
            "speed": "33",
            "timeStamp": "1560319632021",
            "tripID": "7090291482_1560319518940",
            "maneuver_list": [],
            "tripState": "null",
            "eventId": "event_tacticurv_id"
        }
    ]
}

我在alamofire参数中发送的内容：-

let params = [
            "events": [
                [
                    "distance_to_next_route_change": "null",
                    "accelerationX": "0.10055954",
                    "accelerationY": "-0.0047885496",
                    "accelerationZ": "-0.0047885496",
                    "drivingState": "DRIVING",
                    "latitude": "12.921918",
                    "longitude": "77.658917",
                    "next_route_coordinate": "null",
                    "speed": "33",

                    "tripID": "7090291482_1560319518940",
                    "maneuver_list": [],
                    "tripState": "null",
                    "eventId": "event_tacticurv_id"
                ],
                [
                    "distance_to_next_route_change": "null",
                    "accelerationX": "0.10055954",
                    "accelerationY": "-0.0047885496",
                    "accelerationZ": "-0.0047885496",
                    "drivingState": "DRIVING",
                    "latitude": "12.921918",
                    "longitude": "77.658917",
                    "next_route_coordinate": "null",
                    "speed": "33",
                    "timeStamp": "1560319632021",
                    "tripID": "7090291482_1560319518940",
                    "maneuver_list": [],
                    "tripState": "null",
                    "eventId": "event_tacticurv_id"
                ]
            ]
        ]

预期的居所：

{
    "code": "OK",
    "message": "Successfully processed your request",
    "statusCode": 200
}

回应即将来临

{
    "code": "INTERNAL_SERVER_ERROR",
    "message": "Internal server error occured. Please try again later.",
    "statusCode": 500
}

这是完整的代码：-

func testApi() {

    let defaultManager: Alamofire.SessionManager = {
        let serverTrustPolicies: [String: ServerTrustPolicy] = [
            "asia-east2-sandboxkruzr.cloudfunctions.net": .pinCertificates(
                certificates: ServerTrustPolicy.certificates(),
                validateCertificateChain: true,
                validateHost: true
            ),
            "35.220.245.158": .disableEvaluation
        ]

        let configuration = URLSessionConfiguration.default
        configuration.httpAdditionalHeaders = Alamofire.SessionManager.defaultHTTPHeaders

        return Alamofire.SessionManager(
            configuration: configuration,
            serverTrustPolicyManager: ServerTrustPolicyManager(policies: serverTrustPolicies)
        )
    }()

Answer 1

在您的事件中，方括号不正确，需要使用{}来表示单个事件类，而不是表示数组的[]。他们应该看起来像这样。

let params = [
            "events": [
                {
                    "distance_to_next_route_change": "null",
                    "accelerationX": "0.10055954",
                    "accelerationY": "-0.0047885496",
                    "accelerationZ": "-0.0047885496",
                    "drivingState": "DRIVING",
                    "latitude": "12.921918",
                    "longitude": "77.658917",
                    "next_route_coordinate": "null",
                    "speed": "33",
                    "timeStamp": "1560319632021",
                    "tripID": "7090291482_1560319518940",
                    "maneuver_list": [],
                    "tripState": "null",
                    "eventId": "event_tacticurv_id"
                },
                {
                    "distance_to_next_route_change": "null",
                    "accelerationX": "0.10055954",
                    "accelerationY": "-0.0047885496",
                    "accelerationZ": "-0.0047885496",
                    "drivingState": "DRIVING",
                    "latitude": "12.921918",
                    "longitude": "77.658917",
                    "next_route_coordinate": "null",
                    "speed": "33",
                    "timeStamp": "1560319632021",
                    "tripID": "7090291482_1560319518940",
                    "maneuver_list": [],
                    "tripState": "null",
                    "eventId": "event_tacticurv_id"
                }
            ]
        ]

Answer 2

嗯，我不确定，但是问题似乎不在json不好。响应代码是500，代表内部服务器错误，但不是400，代表错误请求

我运行了您的代码，它生成了

{
    "speed": "33",
    "accelerationX": "0.10055954",
    "accelerationY": "-0.0047885496",
    "accelerationZ": "-0.0047885496",
    "distance_to_next_route_change": "null",
    "next_route_coordinate": "null",
    "tripID": "7090291482_1560319518940",
    "maneuver_list": [],
    "tripState": "null",
    "timeStamp": "1560319632021",
    "eventId": "event_tacticurv_id",
    "drivingState": "DRIVING",
    "latitude": "12.921918",
    "longitude": "77.658917",
}

要自己检查，只需添加

let request = defaultManager.request("http...
...
debugPrint(request)

这将打印出您的请求的卷曲表示形式

如何将此Json主体转换为alamofire params格式？
