如何在Swift的Alamofire中发送body参数？

import Alamofire

let parameters: [String: Any] = [
    "key1": "value1",
    "key2": "value2"
]

do {
    let jsonData = try JSONSerialization.data(withJSONObject: parameters, options: .prettyPrinted)
    // 使用jsonData作为请求的body参数
    // ...
} catch {
    print("Error converting parameters to JSON: \(error.localizedDescription)")
}

AF.request("https://example.com/api", method: .post, parameters: nil, encoding: JSONEncoding.default, headers: nil, interceptor: nil)
    .responseJSON { response in
        // 处理响应结果
        // ...
    }
