Question

我是Swift的新手。试图在localhost上发布laravel的帖子请求。验证我的Request在laravel内迅速接收到了Request。我将JSON作为public function verify_login(Request $request) { return response()->json($request) }回复。产生这个错误。

代码3840“JSON文本没有以数组或对象和选项开头允许片段未设置。“

这意味着JSON响应格式错误。

Laravel UserController

 @IBAction func verify_login(_ sender: UIButton) {
    let username: String = self.username.text!
    let passkey: String = self.passkey.text!
    //print(username)
    let urlString = "http://localhost:8888/user/verify"

    guard let requestUrl = URL(string:urlString) else { return }

    let parameters = "username=\(username)&passkey=\(passkey)"
    var request = URLRequest(url:requestUrl)
    request.httpMethod = "POST"
    request.setValue("application/x-www-form-unlencoded;charset=utf-8", forHTTPHeaderField: "Content-Type")
    request.httpBody = parameters.data(using: String.Encoding.utf8)

    let task = URLSession.shared.dataTask(with: request) {
        (data, response, error) in
        if error == nil,let usableData = data {
            var json: [String: Any]?
            do {
                json = try JSONSerialization.jsonObject(with: usableData) as? [String:Any]
                print(json?["username"]! as Any)

            }catch{
                print(error)
            }
        }
    }

    task.resume()
    }

ViewController.swift

Postman

注意：

使用* { margin: 0; padding: 0; border: none; } img { max-width: 100%; } .navbar .navbar-collapse { flex-basis: auto; } @media screen and (max-width:991px){ .navbar .navbar-collapse { flex-basis: 100%; } }我收到预期的响应（请求对象为json）。
Swift结束代码适用于JSON Placeholder API
