功能3: 后台功能:发送短信接口
流程:
获取手机号---->生成6位验证码-->缓存验证码到Redis--->发短信-->返回状态
# 发短信接口
def sms_send(request):
# http://localhost:8000/duanxin/duanxin/sms_send/?phone=18434288349
# 1 获取手机号
phone = request.GET.get(‘phone‘)
# 2 生成6位验证码
code = aliyunsms.get_code(6, False)
# 3 缓存到Redis
cache.set(phone,code,60) #60s有效期
print(‘判断缓存中是否有:‘,cache.has_key(phone))
print(‘获取Redis验证码:‘,cache.get(phone))
# 4 发短信
result = aliyunsms.send_sms(phone, code)
return HttpResponse(result)
功能4: 短信验证码校验
流程:
获取前台电话和验证码----> 获取Redis中存的验证码--->对比是否相等-->返回结果
# 短信验证码校验
def sms_check(request):
# /duanxin/sms_check/?phone=xxx&code=xxx
# 1. 电话和手动输入的验证码
phone = request.GET.get(‘phone‘)
code = request.GET.get(‘code‘)
# 2. 获取redis中保存的code
print(‘缓存中是否包含:‘,cache.has_key(phone))
print(‘取值:‘,cache.get(phone))
cache_code = cache.get(phone)
# 3. 判断
if code == cache_code:
return HttpResponse(json.dumps({‘result‘:‘OK‘}))
else:
return HttpResponse(json.dumps({‘result‘:‘False‘}))
功能5: 统一接口的数据格式:
统一的接口模块restful.py
#encoding: utf-8
from django.http import JsonResponse
class HttpCode(object):
ok = 200
paramserror = 400
methoderror = 405
servererror = 500
# {"code":400,"message":"","data":{}}
def result(code=HttpCode.ok,message="",data=None,kwargs=None):
json_dict = {"code":code,"message":message,"result":data}
if kwargs and isinstance(kwargs,dict) and kwargs.keys():
json_dict.update(kwargs)
return JsonResponse(json_dict,json_dumps_params={‘ensure_ascii‘: False})
def ok(message,data=None):
return result(code=HttpCode.ok,message=message,data=data)
def params_error(message="",data=None):
return result(code=HttpCode.paramserror,message=message,data=data)
def method_error(message=‘‘,data=None):
return result(code=HttpCode.methoderror,message=message,data=data)
def server_error(message=‘‘,data=None):
return result(code=HttpCode.servererror,message=message,data=data)
任何接口的返回结果,都是用resutful.py方法进行规整
# 短信验证码校验
def sms_check(request):
# /duanxin/sms_check/?phone=xxx&code=xxx
# 1. 电话和手动输入的验证码
phone = request.GET.get(‘phone‘)
code = request.GET.get(‘code‘)
# 2. 获取redis中保存的code
print(‘缓存中是否包含:‘,cache.has_key(phone))
print(‘取值:‘,cache.get(phone))
cache_code = cache.get(phone)
# 3. 判断
if code == cache_code:
#格式统一调整后的
return restful.ok("OK",data=None)
else:
#格式统一调整后的
return restful.params_error("验证码错误", data=None)
功能6: 前端短信Ajax两个
$(function(){
//短信验证码
//1. 找标签:btn1
//2. 定时器完成: 显示时间变化!!!
//setInterval(函数, 时间)
//3.难点: 定时器中函数,不断减1, 见到<0终止!!!!
var btn1 = $(‘#sendsms‘)
var count=5; // 倒计时数量 一般为60秒!
var timer =null; //定时器
//事件
btn1.click(function(){
phone = $(‘#phone‘).val()
if(phone==‘‘){
alert(‘请输入电话号码‘)
return false;
}
//ajax
$.ajax({
type: "get",
url: "/reader/sms_send/",
data:"phone="+phone,
success: function(msg){
console.log( "Data Saved: " + msg );
//转换为json
obj = eval("("+msg+")");
console.log(‘结果:‘+obj.Message);
if(obj.Message==‘OK‘){
$(‘#msg‘).html(‘短信发送成功‘)
}else{
$(‘#msg‘).html(‘短信发送失败‘)
}
},
error:function(res){
//状态码
console.log(res.status)
}
});
//end --发送ajax
//特效 start
//禁用
$(this).attr("disabled",‘true‘)
var _this= $(this);
//定时器实现时间每次减少1
timer = setInterval(function(){
count--;
console.log("剩余时间:"+count);
if(count>=0){
//this表示对象!!!! 表示定时器!!!!
//this.innerHTML="时间剩余"+ count+"秒";
_this.html(count+"秒s后重发")
}else{
_this.disabled = false;
clearInterval(timer);
_this.html("重新发送")
count=5
$(‘#sendsms‘).removeAttr("disabled")
}
},1000);
})
//特效 end
//短信验证
$("#smscode").change(function(){
//验证ajax
phone = $(‘#phone‘).val()
code = $(‘#smscode‘).val()
$.ajax({
type: "get",
url: "/reader/sms_check/",
data:"phone="+phone+"&code="+code,
success: function(msg){
console.log( "Data Saved: " + msg );
//已经为json
if(msg.code==‘200‘){
alert(‘成功‘);
}else{
$(‘#msg‘).html(‘手机验证码输入错误‘)
}
},
error:function(res){
//状态码
console.log(res.status)
}
});
//end验证ajax
})
//短信验证end

图文验证码
图文验证码组件
官网 https://django-simple-captcha.readthedocs.io/en/latest/usage.html
参考网站:
https://my.oschina.net/hellotest/blog/1623597
https://blog.csdn.net/ros_donggua/article/details/81024634
第1步:安装图文验证成组件
pip install django-simple-captch
第2步:添加app
# settings.py
INSTALLED_APPS = [
...
‘captcha‘,
]
第3步:添加form表单类
forms.py
#一般将一些表单类写到同一个forms.py文件里
from captcha.fields import CaptchaField
from django import forms
class RegisterForm(forms.Form):
#为生成的验证码图片，以及输入框.
#captcha = CaptchaField(error_messages={‘invalid‘: ‘验证码输入有误‘})
captcha = CaptchaField()
第4步:页面初始化时生成验证码表单项
#跳转到首页时自动生成
def index(request):
#生成验证码表单
register_form = RegisterForm()
return render(request, ‘index.html‘, {‘register_form‘: register_form})
第5步:前端使用
<div class="col-xs-12 col-sm-12 col-md-12 col-lg-12">
验证码:{{ register_form.captcha }}
</div>
此时网页渲染时会自动生成验证码表单
<img src="/captcha/image/2f3f82e5f7a054bf5caa93b9b0bb6cc308fb7011/" alt="captcha"
class="captcha" />
<input id="id_captcha_0" name="captcha_0" type="hidden"
value="2f3f82e5f7a054bf5caa93b9b0bb6cc308fb7011" />
<input autocomplete="off" id="id_captcha_1" name="captcha_1" type="text" />
第6步:验证和刷新
#验证码刷新
def img_refresh(request):
if not request.is_ajax():
return HttpResponse(‘不是Ajax请求‘)
new_key = CaptchaStore.generate_key()
to_json_response = {
‘hashkey‘: new_key,
‘image_url‘: captcha_image_url(new_key),
}
return HttpResponse(json.dumps(to_json_response))
#验证
def img_check(request):
print(‘验证用户输入的图片验证码...‘)
if request.is_ajax():
cs = CaptchaStore.objects.filter(response=request.GET.get(‘code‘),
hashkey=request.GET.get(‘hashkey‘))
print(cs)
if cs:
json_data={‘status‘:1}
else:
json_data = {‘status‘:0}
return JsonResponse(json_data)
else:
# raise Http404
json_data = {‘status‘:0}
return JsonResponse(json_data)
第7步:前端刷新和验证Ajax
<script>
$(function(){
//刷新
$(‘.captcha‘).click(function(){
$.getJSON("/duanxin/img_refresh/",function(result){
$(‘.captcha‘).attr(‘src‘, result[‘image_url‘]);
$(‘#id_captcha_0‘).val(result[‘hashkey‘])
});
return false;
})
//验证
$(‘#id_captcha_1‘).blur(function(){
console.log(‘用户输入的:‘+$(‘#id_captcha_1‘).val())
// 获取输入框和隐藏字段id_captcha_0的数值
code= $(‘#id_captcha_1‘).val();
hashkey=$(‘#id_captcha_0‘).val();
$.getJSON(‘/duanxin/img_check‘,
{‘code‘:code,‘hashkey‘:hashkey},function(res){
//1 验证码正确,0验证码错误
alert(‘验证判断结果...:‘+res)
if(res.status){
$("#msg").html(‘验证码正确‘)
}else{
$("#msg").html(‘验证码错误‘)
}
})
})
})
</script>
<!--短信Ajax-->
第8步:精细化setting配置
# django_simple_captcha 验证码配置其他配置项查看文档
# 默认格式
CAPTCHA_OUTPUT_FORMAT = ‘%(image)s %(text_field)s %(hidden_field)s ‘
CAPTCHA_NOISE_FUNCTIONS = (‘captcha.helpers.noise_null‘, # 没有样式
# ‘captcha.helpers.noise_arcs‘, # 线
# ‘captcha.helpers.noise_dots‘, # 点
)
# 图片中的文字为随机英文字母，如 mdsh
CAPTCHA_CHALLENGE_FUNCT = ‘captcha.helpers.random_char_challenge‘
# 图片中的文字为数字表达式，如2+2=
#CAPTCHA_CHALLENGE_FUNCT = ‘captcha.helpers.math_challenge‘
# 超时(minutes)
CAPTCHA_TIMEOUT = 1
