大多数事情看起来真的很有希望,但我似乎找不到Request.IsAjaxRequest() – 一个在旧的MVC项目中经常使用的功能。
有没有更好的方法来做到这一点 – 这使得他们删除这种方法 – 或者是“隐藏”在别的地方?
感谢任何建议,在哪里找到它或做什么改为!
搜索Ajax
in the MVC6 github repo doesn’t give any relevant results,但您可以自己添加扩展。从MVC5项目中进行的解压缩代码很简单:
/// <summary>
/// Determines whether the specified HTTP request is an AJAX request.
/// </summary>
///
/// <returns>
/// true if the specified HTTP request is an AJAX request; otherwise, false.
/// </returns>
/// <param name="request">The HTTP request.</param><exception cref="T:System.ArgumentNullException">The <paramref name="request"/> parameter is null (Nothing in Visual Basic).</exception>
public static bool IsAjaxRequest(this HttpRequestBase request)
{
if (request == null)
throw new ArgumentNullException(nameof(request));
if (request["X-Requested-With"] == "XMLHttpRequest")
return true;
if (request.Headers != null)
return request.Headers["X-Requested-With"] == "XMLHttpRequest";
return false;
}
由于MVC6 Controller
似乎使用Microsoft.AspNet.Http.HttpRequest,您必须通过对MVC5版本引入少量调整来检查request.Headers
collection是否适合标题:
/// <summary>
/// Determines whether the specified HTTP request is an AJAX request.
/// </summary>
///
/// <returns>
/// true if the specified HTTP request is an AJAX request; otherwise, false.
/// </returns>
/// <param name="request">The HTTP request.</param><exception cref="T:System.ArgumentNullException">The <paramref name="request"/> parameter is null (Nothing in Visual Basic).</exception>
public static bool IsAjaxRequest(this HttpRequest request)
{
if (request == null)
throw new ArgumentNullException("request");
if (request.Headers != null)
return request.Headers["X-Requested-With"] == "XMLHttpRequest";
return false;
}
或直接:
var isAjax = request.Headers["X-Requested-With"] == "XMLHttpRequest"
c# – Asp.Net Core MVC中Request.IsAjaxRequest()在哪里?
