swift将数组发送到web服务参数

import Foundation

// 假设我们有一个用户数组
let users = ["Alice", "Bob", "Charlie"]

// 将数组转换为 JSON 数据
do {
    let jsonData = try JSONSerialization.data(withJSONObject: users, options: [])
    
    // 创建 URL 请求
    guard let url = URL(string: "https://example.com/api/users") else {
        print("Invalid URL")
        return
    }
    
    var request = URLRequest(url: url)
    request.httpMethod = "POST"
    request.setValue("application/json", forHTTPHeaderField: "Content-Type")
    request.httpBody = jsonData
    
    // 发送请求
    let task = URLSession.shared.dataTask(with: request) { data, response, error in
        if let error = error {
            print("Error: \(error)")
            return
        }
        
        if let data = data {
            do {
                let responseJSON = try JSONSerialization.jsonObject(with: data, options: [])
                print("Response: \(responseJSON)")
            } catch {
                print("JSON parsing error: \(error)")
            }
        }
    }
    
    task.resume()
} catch {
    print("JSON serialization error: \(error)")
}

do {
    let jsonData = try JSONSerialization.data(withJSONObject: users, options: [])
} catch {
    print("JSON serialization error: \(error)")
}

request.setValue("application/json", forHTTPHeaderField: "Content-Type")
