django的ajax
-
from表单
-get方式 <from action="/text/" method="get">
user: <input type="text">
pwd: <input type="text">
<input type="submit">
</from>
验证： def text_ajax(request):
if request.method == 'GET':
name = request.GET.get('name')
pw = request.GET.get('pw')
print(request.method)
print(name)
print(pw)

ajax方式
ajax在django中使用ajax困扰了我几天时间，get方式可以直接使用，post则同样需要获取csrftoken，由于没太注意django控制台显示出的信息，一直看的只是浏览器的信息，报的是500的错误，也就是服务器内部错误，我以为是无法找到路由，结果网上查了几天，都没有结果，今天偶然间看到控制台信息，才知道是scrftoken没有携带。
