A：Ajax提交數據是，攜帶的CSRF在data中：

<form method="POST" action="/csrf.html">
    {% csrf_token %}
    <input id="user" type="text" name="user" />
    <input type="submit" value="提交"/>
    <a onclick="submitForm();">Ajax提交</a>
</form>
                
<script src="/static/jquery-1.12.4.js
 
"></script>
<script>
    function submitForm(){
        var csrf = $(‘input[name="csrfmiddlewaretoken"]‘).val();
        var user = $(‘#user‘).val();
        $.ajax({
            url: ‘/csrf.html‘,
            type: ‘POST‘,
            data: {"user":user, ‘csrfmiddlewaretoken‘:csrf},
            success:function(arg){
                console.log(arg);
            }
        })
    }
 
</script>

B：Ajax提交數據是，攜帶的CSRF在請求頭中：

<form method="POST" action="/csrf.html">
    {% csrf_token %}
    <input id="user" type="text" name="user" />
    <input type="submit" value="提交"/>
    <a onclick="submitForm();">Ajax提交</a>
</form>

<script src="/static/jquery-1.12.4.js
 
"></script>
<script src="/static/jquery.cookie.js"></script>

<script>
    function submitForm(){
    var token = $.cookie(‘csrftoken‘);
    var user = $(‘#user‘).val()
    $.ajax({
        url: ‘/csrf.html‘,
    type: ‘POST‘,
    headers:{‘X-CSRFToken‘: token},
    data: { "user":user},
    success:function(arg){
        console.log(arg);
    }
    })
}
</script>
