Django的一个例子
views.py
from django.shortcuts import render
from vlight import v
def index(request, **kwargs):
msgs = []
if request.method == "POST":
valid = v({
"email": "required|email",
"password": "required|min:8|max:255"
}, data=request.POST)
if valid.fails():
msgs = valid.errors().all()
else:
msgs.append("your form submitted!")
return render(request, "index.html", {"login_errors": msgs})
index.html金贾2
<form action="/" method="post">
<input type="hidden" name="csrfmiddlewaretoken" value="{{ csrf_token }}">
<label for="email">email:</label>
<input id="email" type="text" name="email">
<br>
<label for="password">password:</label>
<input id="password" type="password" name="password">
<input type="submit" value="login">
{% for error in login_errors %}
<li><a href="#">{{ error }}</a></li>
{% endfor %}
</form>

"ip"
url模式：^http(s?):\/\/(www\.)?(((\w+(([\.\-]{1}([a-z]{2,})+)+)(\/[a-zA-Z0-9\_\=\?\&\.\#\-\W]*)*$)|(\w+((\.([a-z]{2,})+)+)(\:[0-9]{1,5}(\/[a-zA-Z0-9\_\=\?\&\.\#\-\W]*)*$)))|(([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])\.){3}(([0-9]|([1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5]+)+)(\/[a-zA-Z0-9\_\=\?\&\.\#\-\W]*)*)((\:[0-9]{1,5}(\/[a-zA-Z0-9\_\=\?\&\.\#\-\W]*)*$)*))$
