将表单重新发布到不同的操作（不是来自我的网站）并添加其他数据
我想这样做是因为我需要发布到国外网站，并且希望避免在表单内设置隐藏输入，因为用户可能会更改其中的值（或者其他人可能会为他这样做）
我的html :
<form action="<%=Url.Action("prepare") %>" >
<input type="submit" value="submit" />
</form>
和我的行动
[HttpPost]
public ActionResult Prepare()
{
if(Request.IsAuthenticated)
{
//post to "http://example.com/do"
//and add to the request userId = User.Identity.Name
return //the result of the repost
}
else
{
return RedirectToAction("youneedtobeloggedin",);
}
}
I would like to do this because I need to post to a foreign site, and would like to avoid setting a hidden input inside the form because the user might change the value inside of it (or somebody else might do it for him)
my html:
<form action="<%=Url.Action("prepare") %>" >
<input type="submit" value="submit" />
</form>
and my Action
[HttpPost]
public ActionResult Prepare()
{
if(Request.IsAuthenticated)
{
//post to "http://example.com/do"
//and add to the request userId = User.Identity.Name
return //the result of the repost
}
else
{
return RedirectToAction("youneedtobeloggedin",);
}
}

If you want to keep everything server side, you can take a look at here. It's a simple way to perform POSTs programmatically. In this way you'll handle external POSTs all server side. Please beware that this will make your server perform the POST.
In your controller you can have this Action:
The HttpPost is the function you can find in my link.
