从 mvc5 中的控制器发布到外部表单

Question

我在 mvc5 视图中有一个带有按钮的表单。我需要在控制器中处理这个表单并添加一些从控制器中提取的字段值，然后发布到外部 url。

@using (Html.BeginForm()) 
{
    @Html.AntiForgeryToken()

    <div class="form-horizontal">
        <h4>Deal</h4>
        <hr />
        @Html.ValidationSummary(true)

        <div class="form-group">
            @Html.LabelFor(model => model.First_Name, new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.TextBoxFor(model => model.First_Name, new { @class = "form-control" })
                @Html.ValidationMessageFor(model => model.First_Name)
            </div>
        </div>
        <div class="form-group">
            @Html.LabelFor(model => model.Last_Name, new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.TextBoxFor(model => model.Last_Name, new { @class = "form-control" })
                @Html.ValidationMessageFor(model => model.Last_Name)
            </div>
        </div>
<div class="form-group">
            <div class="col-md-offset-2 col-md-10">
                <input type="submit" value="Save" class="btn btn-default" name="save" /> 
                <input type="submit" value="Register Deal" class="btn btn-default" name="submit" />
            </div>

        </div>

控制器

public ActionResult Create([Bind(Include = "Id,Name,Company,Telephone,Fax,Email,Title,Status,OpportunityAmount,First_Name,Last_Name,City,State,Country,Zip")] Deal deal, String submit)
    {
        if (ModelState.IsValid)
        {
           // do some processing and submit to another external form
        }


    }

关于我们如何做到这一点有什么想法吗？

您可以使用网络请求方法发布。例如。

public void post()
{
    string URL = "http://";
    System.Net.WebRequest webRequest = System.Net.WebRequest.Create(URL);
    webRequest.Method = "POST";
    webRequest.ContentType = "application/x-www-form-urlencoded";
    Stream reqStream = webRequest.GetRequestStream();
    string postData = Request.QueryString; //you form data in get format 
    byte[] postArray = Encoding.ASCII.GetBytes(postData);
    reqStream.Write(postArray, 0, postArray.Length);
    reqStream.Close();
    StreamReader sr = new StreamReader(webRequest.GetResponse().GetResponseStream());
    string Result = sr.ReadToEnd();
}
