如何能够将 NSdictionnary 添加到 HTTP 请求正文中.

How to be able to add an NSdictionnary to the HTTP request body.

这是我的代码，它似乎无法正常工作.

Here is my code, it doesn't seem to work properly.

var entry1 = Response(IdQuestion: 6510,IdProposition: 10,Time: 30) var entry2 = Response(IdQuestion: 8284,IdProposition: 10,Time: 30) Responses.append(entry1) Responses.append(entry2) let list = Responses.map { $0.asDictionary } let json = ["List":list,"IdSurvey":"102","IdUser":"iOSclient","UserInformation":"iOSClient"] let data : NSData = NSKeyedArchiver.archivedDataWithRootObject(json) NSJSONSerialization.isValidJSONObject(json) let myURL = NSURL(string: "www.myserver")! let request = NSMutableURLRequest(URL: myURL) request.HTTPMethod = "POST" request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type") request.setValue("application/json", forHTTPHeaderField: "Accept") request.HTTPBody = data let task = NSURLSession.sharedSession().dataTaskWithRequest(request) { data, response, error in println(response) // Your completion handler code here } task.resume()

推荐答案

试试这个，

// prepare json data let json: [String: Any] = ["title": "ABC", "dict": ["1":"First", "2":"Second"]] let jsonData = try? JSONSerialization.data(withJSONObject: json) // create post request let url = URL(string: "httpbin/post")! var request = URLRequest(url: url) request.httpMethod = "POST" // insert json data to the request request.httpBody = jsonData let task = URLSession.shared.dataTask(with: request) { data, response, error in guard let data = data, error == nil else { print(error?.localizedDescription ?? "No data") return } let responseJSON = try? JSONSerialization.jsonObject(with: data, options: []) if let responseJSON = responseJSON as? [String: Any] { print(responseJSON) } } task.resume()

或尝试一种方便的方式Alamofire
