swift 3 post请求令牌不匹配异常

Question

我将发送请求发送到用php / laravel编写的API路由，

（从laravel doc查看csrf-protecion）

迅速

let request = URLRequest(url: URL(string: "http://my.api/post")!)
        request.httpMethod = "POST"
        request.setValue("Ag1D3YC6DbxuwYNgwUhmNoVkfFnchlrPXQB4rR11", forHTTPHeaderField: "X-CSRF-TOKEN")
        let postString = "id=13&name=Jack"

        request.httpBody = postString.data(using: .utf8)
            URLSession.shared.dataTask(with: request as URLRequest) { data, response, error in
            guard let data = data, error == nil else {
                // check for fundamental networking error
                print("error=\(error)")
                return
            }
            let responseString = String(data: data, encoding: .utf8)
            print("responseString = \(responseString)")
        }.resume()

的PHP / laravel

// route.php
Route::post('post', 'PostController@post');
Route::get('token', function() {
   return csrf_token(); // this is how I get token for request header
}); 
// PostController.php
public function post(Request $request)
{
   return $request->all();
}

我在Swift代码中一直收到TokenMismatchException错误，而我可以通过Postman应用程序成功发布，

任何想法？
