Question

我在所有静态页面中都有登录表单。我在我的项目中启用了csrf中间件。现在，当用户从http静态页面提交表单时，我收到错误

csrf verification failed

是否有办法确保跨站点验证，即使从非简洁页面发布到安全页面也是如此？

我既不想添加scrf豁免装饰器，也不想将页面更改为https。

这是我的模板：

     <form action='{{login_url}}' method = 'post'>
            {% csrf_token %}

            <div class="searchbox login">
 <input autocomplete="off" id="id_fakeusername" type="text" name="fakeusername"    maxlength="100" value='Email' style="color: #727272" onfocus="$('#id_fakeusername').hide();$('#id_username').show();        

$('#id_username').focus();"  />

<input autocomplete="off" type='text' id="id_username" type="text" name="username"  maxlength="100" style="display: none" value='' onblur="if ($('#id_username').attr('value') == '') {$('#id_username').hide();$('#id_fakeusername').show();}"  />
        </div>
        <div class="searchbox login">
            <input autocomplete="off" id="id_fakepassword" type="text" name="fakepassword"  maxlength="50" style="color: #727272" value='Password' onfocus="$('#id_fakepassword').hide(); $('#id_password').show();  $('#id_password').focus();"  />

<input autocomplete="off" type='password' id="id_password" name="password" type="text"  style="display: none" value='' onblur="if ($('#id_password').attr('value') == '') {$('#id_password').hide();$('#id_fakepassword').show();}"  />
        </div>
            {% block nativewin %}
        <div class="loginbut"><input type="submit" border="0" title="Login" value="Login" /></div>
    {% endblock nativewin %}
    </form>

来自CsrfViewMiddleware代码[1]：

            # Suppose user visits http://example.com/
            # An active network attacker (man-in-the-middle, MITM) sends a
            # POST form that targets https://example.com/detonate-bomb/ and
            # submits it via JavaScript.
            #
            # The attacker will need to provide a CSRF cookie and token, but
            # that's no problem for a MITM and the session-independent
            # nonce we're using. So the MITM can circumvent the CSRF
            # protection. This is true for any HTTP connection, but anyone
            # using HTTPS expects better! For this reason, for
            # https://example.com/ we need additional protection that treats
            # http://example.com/ as completely untrusted. Under HTTPS,
            # Barth et al. found that the Referer header is missing for
            # same-domain requests in only about 0.2% of cases or less, so
            # we can use strict Referer checking.

所以我认为你的问题的答案是'不'，使用内置保护！

Answer 2

您是否在template中添加了{{ csrf_token }}？

<form action="/contact/" method="post">{% csrf_token %}
{{ form.as_p }}
<input type="submit" value="Submit" />
</form>

您是否在render_to_response中添加了RequestContext？

from django.template import RequestContext
from django.shortcuts import render_to_response

return render_to_response('contact.html', {'form': form},
                   context_instance=RequestContext(request))

如果仍然无效，请按照docs。
