识别ASP.NET MVC代码中的Angular js AJAX调用 [英] Identify angular js AJAX calls in ASP.NET MVC code

问题描述

我正在使用ASP.NET MVC和AngularJS开发示例应用程序.

I am working on a sample application using ASP.NET MVC and AngularJS.

在服务器端代码中，我编写了一个动作过滤器属性，并需要检查该请求是普通请求(浏览器)还是AJAX请求.

In server side code , I have written a Action filter attribute , and in that I need to check whether the request is a normal request(Browser) or AJAX request.

public override void OnActionExecuting(ActionExecutingContext filterContext)
{
    if ( filterContext.HttpContext.Request.IsAjaxRequest())
     {

     }
}

在使用$ http Angular服务发出AJAX请求的情况下，上述代码段"IsAjaxRequest()"中提到的方法未返回TRUE.

The method mentioned in the above code snippet "IsAjaxRequest()" is not returning TRUE in case of AJAX request made using $http Angular service.

我发现请求没有X-Requested-With标头，甚至添加标头也无法解决请求.

I observed that the request does not have X-Requested-With header , and even adding the header did not solve the request.

注意:这不是CORS呼叫.

Note : This is NOT CORS call.

所以我的问题.

1. filterContext.HttpContext.Request.IsAjaxRequest()如何确定请求是否为AJAX?

1. How does filterContext.HttpContext.Request.IsAjaxRequest() decide whether the request is AJAX or not?

我可以检查请求标头(是否具有特定标头)，并确定请求是否为AJAX.这是正确且唯一的方法吗?

I can check the request header(whether it has a particular header or not) and decide whether the request is AJAX or not. Is it the right and only approach?

推荐答案

它通过查看X-Requested-With标头是否存在来进行确定. 您可以将X-Request-With标头手动添加到$http服务.

It decides by looking whether X-Requested-With header exists or not. You can add X-Request-With header manually to $http service.

个人要求

$http.get('/controller/action', {
   headers: {
    'X-Requested-With': 'XMLHttpRequest'
   }
});

对于每个请求

app.config(['$httpProvider', function ($httpProvider) {
  $httpProvider.defaults.headers.common["X-Requested-With"] = 'XMLHttpRequest';
}]);
