Question

我想在Facebook生日应用中将输入文本从视图传递到控制器：应用链接：http://www.asp.net/mvc/tutorials/mvc-4/aspnet-mvc-facebook-birthday-app

HomeController中的

[FacebookAuthorize("email", "user_photos")]
    public async Task<ActionResult> Index(FacebookContext context)
    {
        if (ModelState.IsValid)
        {
            var user = await context.Client.GetCurrentUserAsync<MyAppUser>();
            return View(user);
        }
        return View("Error");
    }

[HttpPost]
[FacebookAuthorize("email", "user_photos")]
    public async Task<ActionResult> Index(string txt,FacebookContext context)
    {
        if (ModelState.IsValid)
        {
            var user = await context.Client.GetCurrentUserAsync<MyAppUser>();

// my code , I use txt here

            return View(user);
        }
        return View("Error");
    }

视图：

@using facebookpostc.Models
@using Microsoft.AspNet.Mvc.Facebook.Models
@using Microsoft.AspNet.Mvc.Facebook
@model MyAppUser
@{
ViewBag.Title = "Home Page";
}
<article id="content">
<div class="right">
    @using (Html.BeginForm("Index", "HomeController"))
{
<br />
<span>please input your text: </span>
<input type="text" id="txt" name="txt" />   
<input type="submit" />            
} 
</div>
</article>

但它没有传递文本，我试图以多种方式传递文本，但没有传递文本。

您可以从 FormCollection ：

中阅读

[HttpPost]
[FacebookAuthorize("email", "user_photos")]
    public async Task<ActionResult> Index(FormCollection form,FacebookContext context)
    {
        if (ModelState.IsValid)
        {
            string temp = form["txt"].ToString();
            var user = await context.Client.GetCurrentUserAsync<MyAppUser>();

// my code , I use txt here

            return View(user);
        }
        return View("Error");
    }

使用Facebook应用程序通过Facebook上下文将输入文本从视图传递到控制器
