如何通过 Swift 发送 POST 请求?

问题描述

我有这样的控制器 -

I have my controller like this -

def create
   if (@user = User.find_by_email(params[:email])) && @user.valid_password?(params[:password])
      render json: @user.as_json(only: [:email,:authentication_token]),status: :created
   else 
      render json:('Unauthorized Access')
   end  
end 

当我使用 Postman 提出此请求时，我选择正文，并形成数据并添加电子邮件和密码.这个作品

When I use Postman to make this request, I choose Body, and form data and adds in the email and password. And this WORKS

如何使用 swift 来做同样的事情?这是我尝试过的

How to use swift to do the same? This is what I have tried

let url = URL(string: "http://localhost:3000/api/v1/user_serialized/")

let config = URLSessionConfiguration.default

let request = NSMutableURLRequest(url: url!)

request.httpMethod = "POST"

let bodyData = "email=Test@test.com&password=Test1234"

request.httpBody = bodyData.data(using: String.Encoding.utf8);

let session = URLSession(configuration: config)

let task = session.dataTask(with: url! as URL, completionHandler: {(data, response, error) in
    let json = JSON(data:data!)

    debugPrint(json)
})

task.resume()

推荐答案

我认为你应该将你的请求而不是 url 传递给 session.dataTask

I think you should pass your request instead of the url to session.dataTask

这是我的代码的样子:

private let url = URL(string: "http://example.com/")!

func httpPost(jsonData: Data) {
    if !jsonData.isEmpty {
        var request = URLRequest(url: url)
        request.httpMethod = "POST"
        request.httpBody = jsonData

        URLSession.shared.getAllTasks { (openTasks: [URLSessionTask]) in
            NSLog("open tasks: (openTasks)")
        }

        let task = URLSession.shared.dataTask(with: request, completionHandler: { (responseData: Data?, response: URLResponse?, error: Error?) in
            NSLog("(response)")
        })
        task.resume()
    }
}
