How to solve the 403 error when django uses ajax post data

In Django, when using jquery ajax post data, a 403 error will occur. How to solve it? Let me help you solve the 403 error when using ajax post data in Django. Friends who need it can refer to

This article introduces to you two methods in Django. When using jquery ajax post data, a 403 error will occur. , please see below for details.

Method 1:

If you use jQuery to handle ajax, Django directly sends a piece of code to solve the problem. Put it in a separate js file and introduce it in the html page. Note that this js file must be introduced after the jquery js file is introduced

$(document).ajaxSend(function(event, xhr, settings) { 
 function getCookie(name) { 
  var cookieValue = null; 
  if (document.cookie && document.cookie != '') { 
   var cookies = document.cookie.split(';'); 
   for (var i = ; i < cookies.length; i++) { 
    var cookie = jQuery.trim(cookies[i]); 
    // Does this cookie string begin with the name we want? 
    if (cookie.substring(, name.length + ) == (name + &#39;=&#39;)) { 
     cookieValue = decodeURIComponent(cookie.substring(name.length + )); 
     break; 
    } 
   } 
  } 
  return cookieValue; 
 } 
 function sameOrigin(url) { 
  // url could be relative or scheme relative or absolute 
  var host = document.location.host; // host + port 
  var protocol = document.location.protocol; 
  var sr_origin = &#39;//&#39; + host; 
  var origin = protocol + sr_origin; 
  // Allow absolute or scheme relative URLs to same origin 
  return (url == origin || url.slice(, origin.length + ) == origin + &#39;/&#39;) || 
   (url == sr_origin || url.slice(, sr_origin.length + ) == sr_origin + &#39;/&#39;) || 
   // or any other URL that isn&#39;t scheme relative or absolute i.e relative. 
   !(/^(\/\/|http:|https:).*/.test(url)); 
 } 
 function safeMethod(method) { 
  return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method)); 
 } 
 if (!safeMethod(settings.type) && sameOrigin(settings.url)) { 
  xhr.setRequestHeader("X-CSRFToken", getCookie(&#39;csrftoken&#39;)); 
 } 
});

Method 2:

Add @csrf_exempt decoration before the view that processes post data Symbols

For example

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

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
