django中使用jquery ajax post數據出現403錯誤的解決辦法(兩種方法)

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