swift使用xml请求正文构造请求

import Foundation

// 创建XML请求正文
let xmlString = """
<request>
    <param1>value1</param1>
    <param2>value2</param2>
</request>
"""

// 将XML字符串转换为Data类型
guard let xmlData = xmlString.data(using: .utf8) else {
    print("Failed to convert XML string to data")
    return
}

// 创建URL请求
let url = URL(string: "https://example.com/api")!
var request = URLRequest(url: url)

// 设置请求方法和内容类型
request.httpMethod = "POST"
request.setValue("text/xml", forHTTPHeaderField: "Content-Type")

// 设置请求正文
request.httpBody = xmlData

// 发送请求并处理响应
let task = URLSession.shared.dataTask(with: request) { (data, response, error) in
    if let error = error {
        print("Request 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()
