通过Alamofire发送json数组

Question

我想知道是否可以在POST请求中直接发送一个数组（未包装在字典中）。显然，该parameters参数应获取以下内容的映射：[String：AnyObject]？但我希望能够发送以下示例json：

[
    "06786984572365",
    "06644857247565",
    "06649998782227"
]

您可以使用JSON进行编码NSJSONSerialization，然后自行构建NSURLRequest。例如，在Swift 3中：

var request = URLRequest(url: url)
request.httpMethod = "POST"
request.setValue("application/json", forHTTPHeaderField: "Content-Type")

let values = ["06786984572365", "06644857247565", "06649998782227"]

request.httpBody = try! JSONSerialization.data(withJSONObject: values)

Alamofire.request(request)
    .responseJSON { response in
        // do whatever you want here
        switch response.result {
        case .failure(let error):
            print(error)

            if let data = response.data, let responseString = String(data: data, encoding: .utf8) {
                print(responseString)
            }
        case .success(let responseObject):
            print(responseObject)
        }
}
