如何在 Swift 中使用 JSON 正文发出 HTTP Post 请求

问题描述：

我正在尝试使用 JSON 正文发出 HTTP 发布请求:

I'm trying to make an HTTP post request with a JSON body :

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: "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()

答

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()

或尝试一种方便的方式Alamofire
