一, 注册防水墙
1.快速入门文档
https://cloud.tencent.com/document/product/1110/36839
2.注册 AppID 和 AppSecret
3.记录AppID 和 AppSecret
Top~~二, 实现功能
1.准备一个触发的元素,并绑定一个点击事件
<button class="login_btn" id="TencentCaptcha" @click="get_verify">登录</button>
2.get_verify
get_verify() {
// 首先用户名和密码不能为空
if (!this.username || !this.password) {
this.$message.error('用户名和密码均不能为空!');
return;
}
// 首先从后端获取appId
this.$axios.get(`${this.$settings.Host}/users/verify/`).then(
response => {
// 拿到了appId,构建验证码对象
let appId = response.data;
let self = this;
// 这里其实是给这个元素绑定了一个事件
let tct = new TencentCaptcha(document.getElementById("TencentCaptcha"),
appId, function (res) {
// 验证码的回调函数
if (res.ret === 0) {
// 票据
let ticket = res.ticket;
let randstr = res.randstr;
self.check_verify(ticket, randstr)
}
}
);
// 显示验证码
tct.show()
}
).catch(error => {
this.$message.error("获取验证码出错!请联系管理员!")
})
},
3.后端提供appID的代码
# url: /users/verify/
aid = 'xxxxx'
AppSecretKey = 'xxxxx**'
class VerifyAPIView(APIView):
def get(self, request):
return Response(aid, status=status.HTTP_200_OK)
4.check_verify
check_verify(ticket, randstr) {
// 将ticket,randstr发送到后端进行验证
this.$axios.post(`${this.$settings.Host}/users/verify/`, {
'ticket': ticket,
'randstr': randstr
}).then(response => {
if (response.status === 200) {
// 校验成功, 进行登录,这里调用之前写好的登录方法
this.login_handler()
} else {
this.$message.error("校验失败!")
}
}).catch(error => {
this.$message.error("校验验证码出错!请联系管理员!")
})
}
5.后端校验验证码
# 需要安装reuqests包
def post(self, request):
Ticket = request.data.get('ticket')
Randstr = request.data.get('randstr')
# 上线后这里要进行修改,改为动态获取请求的ip
UserIP = '123.112.18.146'
ret = requests.get('https://ssl.captcha.qq.com/ticket/verify', params={
'aid': aid,
'AppSecretKey': AppSecretKey,
'Ticket': Ticket,
'Randstr': Randstr,
'UserIP': UserIP
})
dic = ret.json()
if dic and dic.get('response') == '1':
return Response('校验成功!', status=status.HTTP_200_OK)
return Response(dic.get('err_msg'), status=status.HTTP_400_BAD_REQUEST)
