[django]ajax post提交数据携带csrf

Ajax post提交数据时候，必须携带CSRFtoken,否则会被提示跨域403

解决方法1: 注释掉csrf(Cross-site request forgery)中间件即可

解决方案2: 提交时携带csrf即可

a. 放置在data中携带

注: 需要引入jquery.cookie.js

<form method="POST" action="/csrf1.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: '/csrf1.html',
            type: 'POST',
            data: { "user":user,'csrfmiddlewaretoken': csrf},
            success:function(arg){
                console.log(arg);
            }
        })
    }

</script>

b. 放在请求头中: 需要jquery.cookie.js

<form method="POST" action="/csrf1.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: '/csrf1.html',
            type: 'POST',
            headers:{'X-CSRFToken': token},
            data: { "user":user},
            success:function(arg){
                console.log(arg);
            }
        })
    }
</script>
