In Django, when using jquery ajax post data, a 403 error will occur. Do you know how to solve it? Let me share two solutions with you below. Friends who need it can refer to it

In django, when using jquery ajax post data, a 403 error will occur

Method 1:

If jQuery is used to process ajax, Django I directly sent 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

$(document).ajaxSend(function(event, xhr, settings) { 
  function getCookie(name) { 
    var cookieValue = null; 
    if (document.cookie && document.cookie != &#39;&#39;) { 
      var cookies = document.cookie.split(&#39;;&#39;); 
      for (var i = 0; i < cookies.length; i++) { 
        var cookie = jQuery.trim(cookies[i]); 
        // Does this cookie string begin with the name we want? 
        if (cookie.substring(0, name.length + 1) == (name + &#39;=&#39;)) { 
          cookieValue = decodeURIComponent(cookie.substring(name.length + 1)); 
          break; 
        } 
      } 
    } 
    return cookieValue; 
  } 
  function sameOrigin(url) { 
    // url could be relative or scheme relative or absolute 
    var host = document.location.host; // host + port 
    var protocol = document.location.protocol; 
    var sr_origin = &#39;//&#39; + host; 
    var origin = protocol + sr_origin; 
    // Allow absolute or scheme relative URLs to same origin 
    return (url == origin || url.slice(0, origin.length + 1) == origin + &#39;/&#39;) || 
      (url == sr_origin || url.slice(0, sr_origin.length + 1) == sr_origin + &#39;/&#39;) || 
      // or any other URL that isn&#39;t scheme relative or absolute i.e relative. 
      !(/^(\/\/|http:|https:).*/.test(url)); 
  } 
  function safeMethod(method) { 
    return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method)); 
  } 
  if (!safeMethod(settings.type) && sameOrigin(settings.url)) { 
    xhr.setRequestHeader("X-CSRFToken", getCookie(&#39;csrftoken&#39;)); 
  } 
});

Copy after login

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",&#39;&#39;)

Copy after login

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