Swift 5，发出http post请求

import Foundation

func sendHttpPostRequest() {
    let url = URL(string: "http://example.com/api/endpoint")!  // 替换为实际的URL
    
    var request = URLRequest(url: url)
    request.httpMethod = "POST"
    
    let parameters: [String: Any] = [
        "key1": "value1",
        "key2": "value2"
    ]
    request.httpBody = try? JSONSerialization.data(withJSONObject: parameters, options: [])
    
    let session = URLSession.shared
    let task = session.dataTask(with: request) { (data, response, error) in
        if let error = error {
            print("Error: \(error)")
            return
        }
        
        guard let data = data else {
            print("Data is empty")
            return
        }
        
        // 处理返回的数据
        if let json = try? JSONSerialization.jsonObject(with: data, options: []),
           let response = json as? [String: Any] {
            print("Response: \(response)")
        } else {
            print("Invalid response")
        }
    }
    
    task.resume()
}
