我真的是 swift 新手，在将我拥有的字典转换为我正在调用的 api 接受的 JSON 时遇到了麻烦。

我已经创建了一个包含相关数据的字典并将其转换为 JSON。

例子：---

let requestbody = ["content": ["app_version_name": , "device_locale": , "device_model": , "device_id": , "os_run_time": , "device_time_zone": , "__type": "", "device_type": , "os_build_type": , "installation_id": "", "cloud_version": , "os_version": , "app_package_name": ]]

let jsonData = try? JSONSerialization.data(withJSONObject: requestBody)
let convertedString = String(data: jsonData!, encoding: String.Encoding.utf8)

但是在打印转换后的字符串时，我得到了：

{
  "content": {
"installation_id": "",
"device_type": "",
"device_id": "",
"device_model": "",
"device_time_zone": "",
"cloud_version": "",
"os_run_time": "",
"device_locale": "",
"app_version_name": "",
"app_package_name": "",
"os_build_type": "",
"os_version": "",
"__type": ""
  }
}

我期待的结果是

{
  "content": [
{
"installation_id": "",
"device_type": "",
"device_id": "",
"device_model": "",
"device_time_zone": "",
"cloud_version": "",
"os_run_time": "",
"device_locale": "",
"app_version_name": "",
"app_package_name": "",
"os_build_type": "",
"os_version": "",
"__type": ""
    }
 ]
}

基本上我需要帮助将内容的值放在 jsonArray 中。

【解决方案1】：

只需将整个内容结构包装在另一个数组中：

let content = ["app_version_name": "", "device_locale": "", "device_model": "", "device_id": "", "os_run_time": "", "device_time_zone": "", "__type": "", "device_type": "", "os_build_type": "", "installation_id": "", "cloud_version": "", "os_version": "", "app_package_name": ""]
let requestbody = ["content": [content]]
