如何在 mvc3 中获取 CURL 值？

Question

我是 MVC 的新手。我在使用带有 sql server 2005 的 asp.net MVC3 使用以下程序。我使用以下代码它工作正常。我的问题是如何更改此程序，例如如何获取值从 CURL(php) 而不是注册表单值并将该值添加到 sql server 2005 中？

UserManager.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using MvcDemo.Models.DB;
using MvcDemo.Models.ViewModels;

namespace MvcDemo.Models
{
    public class UserManager
    {
        private UserView obj = new UserView();

        public void Add(UserView user)
        {
            obj.FirstName = user.FirstName;

            DB.Signup sysUser = new Signup();
            sysUser.FirstName = user.FirstName;
            sysUser.LastName = user.LastName;
            sysUser.Contactnumber = Int32.Parse(user.ContactNumber);
            sysUser.LoginID = user.LoginID;
            sysUser.Password = user.Password;
            obj.AddToSysUsers(sysUser);
                      }

                }
}

AccountController.cs


using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Security;
using MvcDemo.Models.ViewModels;
using MvcDemo.Models;


namespace MvcDemo.Controllers
{

    public class AccountController : Controller
    {

        public ActionResult SignUp()
        {
            return View("SignUp");
        }




        [HttpPost]
        public ActionResult SignUp(UserView user)
        {
            try
            {
                if (ModelState.IsValid)
                {
                    UserManager userManager = new UserManager();

                        userManager.Add(user);
                        FormsAuthentication.SetAuthCookie(user.FirstName, false);
                        return RedirectToAction("Welcome", "Home");

                }
            }
            catch
            {
                return View(user);
            }

            return View(user);
        }
    }
}

Answer 1

我很难理解你真正想要做什么。但是，如果我理解你是正确的，你想通过 PHP 和 cURL 提交注册表单。这就是您使用 cURL 提交 HTTP 帖子的方式：

<?php
$data = array(
    'FirstName' => 'The firstname value',
    'LastName ' => 'The lastname value',
    'ContactNumber ' => 'The contactnumber value',
    'LoginID ' => 'The loginid value',
    'Password ' => 'The password value'
);

$post = http_build_query($data);

$url = 'http://url_to_your_server/Account/SignUp/';
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$response = curl_exec($ch);

var_dump($response);

Answer 2

不太清楚获取注册表单变量是什么意思，您应该可以很容易地从传递给您的操作的模型中做到这一点。

如果您的意思是，如何获得模型中不存在的外部值，则需要使用。 Request 属性。

public ActionResult Register(...) {
    var x = Request.Form["your form value here"] // for forms
    var y = Request.QueryString["your query string value here"] // for query strings
    var z = Request.Headers["for headers"] // for headers
    ... etc ...
}

如果您能进一步澄清您的问题，您可能会得到一些更好的答案，目前我们还不清楚您的目标。
