如何在swift中使用POST请求附加多个数据。作为邮递员附加的屏幕截图，选择x - www-form-urlencoded选项时工作正常如何在身体上附加5个数据，如'x-www-form-urlencoded'选项。

这里是代码，

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

        var urlComponents = URLComponents()
        urlComponents.queryItems = [
            URLQueryItem(name: “***”, value: “***”),
            URLQueryItem(name: "***", value: "***"),
            URLQueryItem(name: "***", value: "***"),
            URLQueryItem(name: "***", value: "***"),
            URLQueryItem(name: "***", value: "***"),
        ]
        request.httpBody = urlComponents.percentEncodedQuery?.data(using: String.Encoding.utf8)

        let loadDataTask = URLSession.shared.dataTask(with: request) { (data, response, error) in
            if let _ =  error{
                completion(false,error)
            }
            else if let response = response as? HTTPURLResponse{
                if response.statusCode != 200{
                    completion(false,error)
                }
                else{
                    do{
                        if let parsedData = try? JSONSerialization.jsonObject(with: data!, options: []){
                            let ff = parsedData as? Dictionary<String,Any>
                            print(ff)
                        }
                    }
                }

            }
        }//let loadDataTask
        loadDataTask.resume()
    }

Answer 1

SWIFT 4：

let url = URL(string: “url”);
var urlRequest = URLRequest(url: url!)
urlRequest.setValue("application/x-www-form-urlencoded",forHTTPHeaderField: "Content-Type")
urlRequest.httpMethod = "POST"
let postString = “paramerter1=value1&parameter2=value2”
urlRequest.httpBody = postString.data(using: .utf8)

Answer 2

创建http正文的一种简单方法是使用URLComponents，如下所示：

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)
