在django中，使用jquery ajax post数据，会出现403的错误

在django中，使用jquery ajax post数据，会出现403的错误

方法一：

如果用jQuery来处理ajax的话，Django直接送了一段解决问题的代码。把它放在一个独立的js文件中，在html页面中都引入即可。注意这个js文件必须在jquery的js文件引入之后，再引入即可

[javascript] view plaincopyprint?

1. $(document).ajaxSend(function(event, xhr, settings) {  
2.     function getCookie(name) {  
3.         var cookieValue = null;  
4.         if (document.cookie && document.cookie != '') {  
5.             var cookies = document.cookie.split(';');  
6.             for (var i = 0; i < cookies.length; i++) {  
7.                 var cookie = jQuery.trim(cookies[i]);  
8.                 // Does this cookie string begin with the name we want?  
9.                 if (cookie.substring(0, name.length + 1) == (name + '=')) {  
10.                     cookieValue = decodeURIComponent(cookie.substring(name.length + 1));  
11.                     break;  
12.                 }  
13.             }  
14.         }  
15.         return cookieValue;  
16.     }  
17.     function sameOrigin(url) {  
18.         // url could be relative or scheme relative or absolute  
19.         var host = document.location.host; // host + port  
20.         var protocol = document.location.protocol;  
21.         var sr_origin = '//' + host;  
22.         var origin = protocol + sr_origin;  
23.         // Allow absolute or scheme relative URLs to same origin  
24.         return (url == origin || url.slice(0, origin.length + 1) == origin + '/') ||  
25.             (url == sr_origin || url.slice(0, sr_origin.length + 1) == sr_origin + '/') ||  
26.             // or any other URL that isn't scheme relative or absolute i.e relative.  
27.             !(/^(\/\/|http:|https:).*/.test(url));  
28.     }  
29.     function safeMethod(method) {  
30.         return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));  
31.     }  
32.   
33.     if (!safeMethod(settings.type) && sameOrigin(settings.url)) {  
34.         xhr.setRequestHeader("X-CSRFToken", getCookie('csrftoken'));  
35.     }  
36. });  

$(document).ajaxSend(function(event, xhr, settings) {    function getCookie(name) {        var cookieValue = null;        if (document.cookie && document.cookie != '') {            var cookies = document.cookie.split(';');            for (var i = 0; i < cookies.length; i++) {                var cookie = jQuery.trim(cookies[i]);                // Does this cookie string begin with the name we want?                if (cookie.substring(0, name.length + 1) == (name + '=')) {                    cookieValue = decodeURIComponent(cookie.substring(name.length + 1));                    break;                }            }        }        return cookieValue;    }    function sameOrigin(url) {        // url could be relative or scheme relative or absolute        var host = document.location.host; // host + port        var protocol = document.location.protocol;        var sr_origin = '//' + host;        var origin = protocol + sr_origin;        // Allow absolute or scheme relative URLs to same origin        return (url == origin || url.slice(0, origin.length + 1) == origin + '/') ||            (url == sr_origin || url.slice(0, sr_origin.length + 1) == sr_origin + '/') ||            // or any other URL that isn't scheme relative or absolute i.e relative.            !(/^(\/\/|http:|https:).*/.test(url));    }    function safeMethod(method) {        return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));    }    if (!safeMethod(settings.type) && sameOrigin(settings.url)) {        xhr.setRequestHeader("X-CSRFToken", getCookie('csrftoken'));    }});

方法二：

在处理post数据的view前加@csrf_exempt装饰符

例如

[python] view plaincopyprint?

1. @csrf_exempt  
2. def profile_delte(request):  
3.     del_file=request.POST.get("delete_file",'')  
4.
