结合session
check_code.py(依赖Pillow、字体)
点击更换时，要将src属性后面+？，这里可以通过js或jQuery实现

有下面一段代码，想将这段代码中的字符串渲染到HTML页面中，默认Django是不能这样去操作的
def user_list(request): page_str = """ <a href="/user_list/?p=1">1</a> <a href="/user_list/?p=2">2</a> <a href="/user_list/?p=3">3</a> """ return render(request, "user_list.html", {"page_str": page_str})
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <ul> {% for item in li %} {% include "li.html" %} {% endfor %} </ul> <div> {{ page_str }} </div> </body> </html>
<li>{{ item }}</li>
渲染后的页面只能以字符串的形式显示我们传入的HTML代码
Django认为这存在危险，可能会存在代码被注入的可能，我们可以通过下面两种方式解决
{{ page_str|safe }}
from django.utils.safestring import mark_safe def user_list(request): page_str = """ <a href="/user_list/?p=1">1</a> <a href="/user_list/?p=2">2</a> <a href="/user_list/?p=3">3</a> """ page_str = mark_safe(page_str) return render(request, "user_list.html", {"page_str": page_str})
