{% autoescape off %}{{msg}}{% endautoescape %}

但它仍然显示html标签？

尝试这个：

{% filter escape %} msg {% endfilter %}

或者您可能需要使用 force_escape 过滤器，具体取决于情况

似乎您想将您的 html 内容放在某个变量中并且不希望它在模板中转义并希望它用作普通的 html。在这种情况下，

msg = "<p>Location</p>"
{% autoescape off %}{{msg}}{% endautoescape %}

我不完全跟随你，但你试过吗

{{ msg|safe }}

如果您的转义文本来自模型中的字段（或以另一种方式来自后端），您可以（除了人们已经说过的）mark_safe在 Python 代码中使用，而不是在模板中做任何事情。见这里：https ://docs.djangoproject.com/en/dev/ref/utils/#django.utils.safestring.mark_safe

假设模型中的字段始终填充有将自动转义的字符：您可能希望向模型添加一个方法，该方法返回标记为安全的值。例如：

from django.utils.safestring import mark_safe

class Something(models.Model):
    html_text = models.CharField(max_length=30)
    #...

    def get_html(self):
        return mark_safe(self.html_text)

然后在您的模板中，您只需使用{{ my_something.get_html }}
