创建 http 主体的一种简单方法是URLComponents像这样使用：

var request = URLRequest(url: yourUrl)
request.httpMethod = "POST"
request.setValue("application/x-www-form-urlencoded;charset=UTF-8", forHTTPHeaderField: "Content-Type")

var urlComponents = URLComponents()
urlComponents.queryItems = [
    URLQueryItem(name: "your_first_parameter", value: "someValue"),
    URLQueryItem(name: "your_second_parameter", value: "someValue"),
    URLQueryItem(name: "your_third_parameter", value: "someValue")
]
request.httpBody = urlComponents.percentEncodedQuery?.data(using: .utf8)
