swift - 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(不包含在字典中)。显然 parameters 参数应该得到一个映射:[String: AnyObject]？ 但我希望能够发送以下示例 json:

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

您可以使用 NSJSONSerialization 对 JSON 进行编码，然后自己构建 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)

AF.request(request)                               // Or `Alamofire.request(request)` in prior versions of Alamofire
    .responseJSON { response in
        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)
        }
}
