iOS swift Post请求 [英] iOS swift Post request

问题描述

所以我想用以下输出创建一个帖子请求：

So I want to create a post request with the following output:

"user"=>{"email"=>"[e-mail]", "password"=>"[FILTERED]", "password_confirmation"=>"[FILTERED]"}

相反，我得到：

{"user[password_confirmation]"=>"[FILTERED]", "user[email]"=>"[e-mail]", "user[password]"=>"[FILTERED]", "user"=>{}}

这是我用来发布此帖子请求的代码：

This is the code I use to make this post request:

let request = NSMutableURLRequest(URL: NSURL(string: urlString)!)
        let session = NSURLSession.sharedSession()
        let params = ["user[email]":username.text!, "user[password]":password.text!, "user[password_confirmation]":passwordRepeated.text!]

        request.HTTPBody = try? NSJSONSerialization.dataWithJSONObject(params, options: [])
        request.addValue("application/json", forHTTPHeaderField: "Content-Type")
        request.addValue("application/json", forHTTPHeaderField: "Accept")
        request.HTTPMethod = "POST"

        let task = session.dataTaskWithRequest(request, completionHandler: { data, response, error -> Void in

            print(request.HTTPBody)
            print(params)
            print(error)
            print(response)
            print(data)
        })

        task.resume()

那么如何正确创建我的参数？

So how do I correctly create my params?

推荐答案

你正在错误地组成参数。

You are composing params incorrectly.

这样做，

   let params = [
        "user": [
            "email": username.text!,
            "password": password.text!,
            "password_confirmation": passwordRepeated.text!
        ]
    ]
