如何在使用Swift发帖时添加多个参数

func createPostRequest(with parameters: [String: String]) {
    // 将参数拼接到URL中
    var urlString = "https://example.com/post?"
    for (key, value) in parameters {
        let encodedKey = key.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)!
        let encodedValue = value.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)!
        urlString += "\(encodedKey)=\(encodedValue)&"
    }
    
    // 创建URL对象
    guard let url = URL(string: urlString) else {
        print("无效的URL")
        return
    }
    
    // 创建请求对象
    let request = URLRequest(url: url)
    
    // 发送请求...
    // 这里可以使用URLSession等方式发送请求
}

// 示例用法
let parameters = [
    "title": "我的帖子",
    "content": "这是我的帖子内容",
    "category": "技术讨论"
]

createPostRequest(with: parameters)
