我正在尝试使用JSON正文发出HTTP post请求：
如何将NSdictionnary添加到HTTP请求正文中。
这是我的代码，它似乎无法正常工作。
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: "http://www.myserver.com")!
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()

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: "http://httpbin.org/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()
或尝试方便Alamofire

Swift 3和4
@Html.ActionLink("Edit", "Edit", new { /* id=item.PrimaryKey */}) |
@Html.ActionLink("Details", "Details", new { /* id=item.PrimaryKey */ }) |
@Html.ActionLink("Delete", "Delete", new { /* id=item.PrimaryKey */ })
在Swift 4中使用HTTP POST request
URLSession API使用Alamofire：
func postRequest(username: String, password: String, completion: @escaping ([String: Any]?, Error?) -> Void) {
//declare parameter as a dictionary which contains string as key and value combination.
let parameters = ["name": username, "password": password]
//create the url with NSURL
let url = URL(string: "https://www.myserver.com/api/login")!
//create the session object
let session = URLSession.shared
//now create the Request object using the url object
var request = URLRequest(url: url)
request.httpMethod = "POST" //set http method as POST
do {
request.httpBody = try JSONSerialization.data(withJSONObject: parameters, options: .prettyPrinted) // pass dictionary to data object and set it as request body
} catch let error {
print(error.localizedDescription)
completion(nil, error)
}
//HTTP Headers
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("application/json", forHTTPHeaderField: "Accept")
//create dataTask using the session object to send data to the server
let task = session.dataTask(with: request, completionHandler: { data, response, error in
guard error == nil else {
completion(nil, error)
return
}
guard let data = data else {
completion(nil, NSError(domain: "dataNilError", code: -100001, userInfo: nil))
return
}
do {
//create json object from data
guard let json = try JSONSerialization.jsonObject(with: data, options: .mutableContainers) as? [String: Any] else {
completion(nil, NSError(domain: "invalidJSONTypeError", code: -100009, userInfo: nil))
return
}
print(json)
completion(json, nil)
} catch let error {
print(error.localizedDescription)
completion(nil, error)
}
})
task.resume()
}
@objc func submitAction(_ sender: UIButton) {
//call postRequest with username and password parameters
postRequest(username: "username", password: "password") { (result, error) in

request.addValue("application/json",forHTTPHeaderField: "Content-Type")
request.addValue("application/json",forHTTPHeaderField: "Accept")
request.HTTPBody = data
HTTPsendRequest(request, callback: callback)
}
func HTTPsendRequest(request: NSMutableURLRequest,
callback: (String, String?) -> Void) {
let task = NSURLSession.sharedSession()
.dataTaskWithRequest(request) {
(data, response, error) -> Void in
if (error != nil) {
callback("", error.localizedDescription)
} else {
callback(NSString(data: data,
encoding: NSUTF8StringEncoding)! as String, nil)

//use
