NSURLRequest ：发布数据并读取发布的页面

使用NSURLRequest发布数据并读取发布的页面

swift
// 创建请求的URL
let url = URL(string: "https://example.com/post")!
// 创建POST请求
var request = URLRequest(url: url)
request.httpMethod = "POST"
// 设置请求体
let postData = "name=John&age=30"
request.httpBody = postData.data(using: .utf8)
// 发送请求并获取返回的数据
let session = URLSession.shared
let task = session.dataTask(with: request) { (data, response, error) in
    if let error = error {
        print("请求失败: \(error)")
    } else if let data = data {
        // 解析返回的数据
        let responseString = String(data: data, encoding: .utf8)
        print("服务器返回的页面内容: \(responseString ?? "")")
    }
}
task.resume()

swift
// 创建请求的URL
let url = URL(string: "https://example.com/post")!
// 创建POST请求
var request = URLRequest(url: url)
request.httpMethod = "POST"
// 设置请求头
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
// 设置请求体
let parameters = [
    "name": "John",
    "age": "30"
]
request.httpBody = try? JSONSerialization.data(withJSONObject: parameters)
// 发送请求并获取返回的数据
let session = URLSession.shared
let task = session.dataTask(with: request) { (data, response, error) in
    if let error = error {
        print("请求失败: \(error)")
    } else if let data = data {
        // 解析返回的数据
        let responseString = String(data: data, encoding: .utf8)
        print("服务器返回的页面内容: \(responseString ?? "")")
    }
}
task.resume()
