ios - 如何使用 Alamofire 创建 JSON 并将其发送到服务器？

Question

我想向服务器发送一个 JSON，其中包含用户的详细信息和用户选择的选项。目前我只是将它们保存在简单的数组中。

我想创建一个 JSON 并将其发送到服务器。通常我可以用 Alamofire 在参数上添加每个字段。但是这里我有一个问题是，字段的数量取决于用户数量(或乘客数量)。

我以前没有做过这种类型，我是 iOS 开发的新手。

}

这是我的 JSON。这里 flight1 flight2 .... 的数量取决于用户选择的航类数量。

passengers 中对象的数量取决于用户选择的乘客数量。

我该怎么做这部分？

Answer 1

尝试创建一个 [String: Any] 类型的字典，如下例所示。

let param : [String: Any] = ["contactPerson": [ "email":[ "email": "text@mail.com"], "markedForSendingRezInfo": false], "personName": [], "curr": "USD", "flight1" : [], "flight2" : [] ]

您可以根据请求参数要求在param中添加key值。然后将此参数传递给 alamofire 请求参数。
