python代码
需要用到：django.utils.safestring.make_safe
例子：
from django.utils.safestring import mark_safe
def index(request):
s = "<h1>index page</h1>"
s = mark_safe(s)
return render(request, "app01/index.html", {"h1Tag": s}
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>app01 index</title>
</head>
<body>
{{ h1Tag }}
</body>
</html>
template标签和过滤器
safe过滤器和autoescape可以控制，是否将字符串渲染成html代码。
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>app01 index</title>
</head>
<body>
{{ h1Tag }}
{{ h1Tag | safe }}
{% autoescape off %}
{{ h1Tag }}
{% endautoescape %}
</body>
</html>
