从Swift发出发送POST请求

import Foundation

func sendPostRequest() {
    let url = URL(string: "https://example.com/api/endpoint")!
    var request = URLRequest(url: url)
    request.httpMethod = "POST"
    
    // 设置请求头部信息
    request.setValue("application/json", forHTTPHeaderField: "Content-Type")
    request.setValue("Bearer token", forHTTPHeaderField: "Authorization")
    
    // 设置请求参数
    let parameters = ["key1": "value1", "key2": "value2"]
    let jsonData = try? JSONSerialization.data(withJSONObject: parameters)
    request.httpBody = jsonData
    
    let task = URLSession.shared.dataTask(with: request) { (data, response, error) in
        if let error = error {
            print("Error: \(error)")
            return
        }
        
        if let data = data {
            // 处理响应数据
            let responseString = String(data: data, encoding: .utf8)
            print("Response: \(responseString ?? "")")
        }
    }
    
    task.resume()
}
