众里寻他千百度，蓦然回首，那人却在灯火阑珊处。
百度的结果千篇一律，真正可行性解决方案万里挑一，接下来就介绍下django实现百分百可复制的登录功能。
效果展示
为支持验证码功能，因此需要安装一些rpm包及python功能包，具体如下：
; centos安装组件包
1、安装jpegsrc.v9d.tar.gz，解压后执行如下指令：
./configure --enable-shared
make && make install
python功能包安装
1、安装django-ranged-response-0.2.0.tar.gz，解压后执行如下指令：
python3 setup.py install
2、安装Pillow-8.3.1.tar.gz，解压后执行如下指令：
python3 setup.py install
3、安装six-1.16.0.tar.gz，解压后执行如下指令：
python3 setup.py install
4、安装django-simple-captcha-0.5.14.zip，解压后执行如下指令：
python3 setup.py install
至此，验证码相关依赖组件安装完成，可以愉快的玩耍啦。
py代码
1、settings.py增加配置’captcha’
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'captcha',
]
2、urls.py增加配置：
from django.conf.urls import url
from django.conf.urls import include
url(r'^$',selectpg.index),
url(r'^login/',selectpg.login),
url(r'^logout/',selectpg.logout),
url(r'^captcha/',include('captcha.urls')),
3、selectpg.py增加配置：
from django.shortcuts import render,redirect
import hashlib
from . import myform
def index(request):
request.encoding='utf-8'
response={}
if not request.session.get('is_login',None) :
return redirect('/login/')
if request.session.get('user_name',None):
condition={}
condition['user_name']=request.session.get('user_name')
user_list=modelcontrol.select(condition,'User_List',models,'id').first()
response['user_list']= user_list
return render(request,'index.html',response)
def login(request):
if request.session.get('is_login', None):
return redirect('/')
if request.method == "POST":
login_form = myform.UserForm(request.POST)
if login_form.is_valid():
username = login_form.cleaned_data['username']
password = login_form.cleaned_data['password']
try:
user = User_List.objects.get(user_name=username)
if user.password == hash_code(password):
request.session['is_login'] = True
request.session['user_id'] = user.id
request.session['user_name'] = user.user_name
return redirect('/')
else:
message = "密码不正确！"
except:
message = "用户不存在！"
return render(request, 'login.html', locals())
login_form = myform.UserForm()
return render(request, 'login.html', locals())
def logout(request):
if not request.session.get('is_login', None):
return redirect("/login/")
request.session.flush()
return redirect('/login/')
4、myform.py增加配置
from captcha.fields import CaptchaField, CaptchaTextInput
from django import forms
class UserForm(forms.Form):
username = forms.CharField(label="账号", max_length=16, widget=forms.TextInput(attrs={'class': 'form-control'}))
password = forms.CharField(label="密码", max_length=16, widget=forms.PasswordInput(attrs={'class': 'form-control'}))
captcha = CaptchaField(label='验证码', widget=CaptchaTextInput(attrs={'class': 'form-control'}))
html代码
<form class="form-signin" action="/login/" method="post">
<div class="text-center mb-4">
<img class="mb-4" height="72" src="/assets/img/cec-blue.png" />
div>
{% if message %}
<div class="form-group">{{message}}
div>
{% endif %}
{% csrf_token %}
<div class="form-group">
{{ login_form.username.label_tag}}
{{ login_form.username}}
div>
<div class="form-group">
{{ login_form.password.label_tag}}
{{ login_form.password}}
div>
<div class="form-group">
{{ login_form.captcha.label_tag }}
{{ login_form.captcha }}
div>
<button class="btn btn-lg btn-primary btn-block" type="submit">登录button>
form>
script脚本
主要实现验证码切换功能。
<script src="/assets/js/jquery-2.1.4.min.js"></script>
<script>
$(function () {
$('img.captcha').click(function () {
var $form = $(this).parents('form');
var url = location.protocol + "//" + window.location.hostname + ":"
+ location.port + "/captcha/refresh/";
$.getJSON(url, {}, function (json) {
$form.find('input[name="captcha_0"]').val(json.key);
$form.find('img.captcha').attr('src', json.image_url);
});
return false;
});
});
</script>
至此大功告成，万事大吉。
