Alamofire：在参数中发送数组

Question

我尝试按以下格式在POST请求参数中发送数组：

{  "ratings": [{
   "safety_rating_id": 105,
   "schedule_job_id": 18,
   "score": 9,
   "submission_id": 27
}, 
{
   "safety_rating_id": 105,
   "schedule_job_id": 18,
   "score": 9,
   "submission_id": 27
}]
}

我试图包装我的数组但是我被抛出了这个错误：

  

上下文类型＆＃39;数组＆＃39; （又名＆＃39;数组＆gt;＆＃39;）不能与字典文字

一起使用

POST请求代码：

 let comments: Array<[String:AnyObject]> = [
        "ratings" : [
                [
                    "safety_rating_id" : 106,
                    "schedule_job_id" : 18,
                    "score" : 10,
                    "submission_id" : 27
                ],
                [
                    "safety_rating_id" : 105,
                    "schedule_job_id" : 18,
                    "score" : 9,
                    "submission_id" : 27
                ]
            ]
    ]
Alamofire.request(.POST, endPoint, headers: Auth_header, parameters: comments)
        .validate()
        .responseData {
        response in

        switch response.result {
        case .Success(let data):
            let json = JSON(data)
            print(json)
            onCompletion()
        case .Failure(let error):
            print("Request failed with error: \(error)")
            onError?(error)
        }

    }

你写

let comments: Array<[String:AnyObject]> 

但你放在那里的内容是一个字典，而不是一个数组。

将comments的签名更改为简单字典：

let comments: [String:AnyObject] = [
    "ratings" : [
        [
            "safety_rating_id" : 106,
            "schedule_job_id" : 18,
            "score" : 10,
            "submission_id" : 27
        ],
        [
            "safety_rating_id" : 105,
            "schedule_job_id" : 18,
            "score" : 9,
            "submission_id" : 27
        ]
    ]
]

或者，如果您需要完整类型：

let comments: [String:[[String:Int]]] = [
    "ratings" : [
        [
            "safety_rating_id" : 106,
            "schedule_job_id" : 18,
            "score" : 10,
            "submission_id" : 27
        ],
        [
            "safety_rating_id" : 105,
            "schedule_job_id" : 18,
            "score" : 9,
            "submission_id" : 27
        ]
    ]
]
