如何将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

尝试一下，

// 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()
