从Web Api控制器中的Post方法获取任何参数
[英]Get any parameter from a Post Method in a Web Api controller
问题描述
I've an old page made in aspx that get every Request.Form.Keys and made a POST using a form to another page (is like an "HTTP POST REDIRECT") 
我有一个用aspx制成的旧页面，该页面可以获取每个Request.Form.Keys并使用表单向另一个页面进行POST（就像“ HTTP POST REDIRECT”一样）
Now this system must be migrated to Web API (2.1) and I must emulate the same. 现在，该系统必须迁移到Web API（2.1），并且我必须进行模拟。
The trick with this is that the aspx gets any/multiple keys and values, you can post anything to the aspx. 诀窍在于，aspx获取任何/多个键和值，您可以将任何内容发布到aspx。 But I can't get the same result with my POST method in web api, because it expects the object as is (and I don't know it and I don't care) 但是我在Web api中的POST方法无法获得相同的结果，因为它希望对象保持原样（而且我也不知道，我不在乎）
I don't know if this can help, but the code of the old aspx is like this one: 我不知道这是否可以帮助您，但是旧aspx的代码如下：
sb.Append("<html>");
sb.AppendFormat("<body onload='document.forms[0].submit()'>Loading...");
sb.AppendFormat("<form action='{0}' method='post'>",
the-next-url);
foreach (string key in Request.Form.Keys)
{
sb.AppendFormat("<input type='hidden' name='{0}' value='{1}'>", key, Request.Form[key]);
}
sb.Append("</form>");
sb.Append("</body>");
sb.Append("</html>");
Response.Write(sb.ToString());

Finally, I just use inside my method: 最后，我只在方法内部使用：
HttpContext.Current.Request.Form
to get all POST keys and values instead of Request.Form 获取所有POST键和值而不是Request.Form

You could refactor your code, I suppose, to use something like this: 我想，您可以重构代码以使用如下代码：
if (HttpContext.Current.Request.Form.Count > 0)
{
sb.Append("<html>");
sb.AppendFormat("<body onload='document.forms[0].submit()'>Loading...");
sb.AppendFormat("<form action='{0}' method='post'>",your_url);
foreach (string key in HttpContext.Current.Request.Form.AllKeys)
{
sb.AppendFormat("<input type='hidden' name='{0}' value='{1}'>", key,
HttpContext.Current.Request.Form[key]);
}
sb.Append("</form>");
sb.Append("</body>");
sb.Append("</html>");
}
