[Python知识库]Django电商项目（八）短信验证码的前后端实现

这篇文章我们开始完成短信验证码的前后端逻辑
后端逻辑
短信验证码接口设计

class SMSCodeView(View):
    """短信验证码"""

    def get(self, request, mobile):
        """
        :param mobile: 手机号
        :return: JSON
        """
        # 接收参数
        image_code_client = request.GET.get('image_code')
        uuid = request.GET.get('uuid')
        # 校验参数
        if not all([image_code_client, uuid]):
            return HttpResponseForbidden('缺少必传参数')
        # 创建连接到redis的对象
        redis_conn = get_redis_connection('verify_code')

        # 提取图形验证码
        image_code_server = redis_conn.get("img_%s" % uuid)
        # 删除图形验证码，避免恶意测试图形验证码
        redis_conn.delete("img_%s" % uuid)
        # 对比图形验证码
        if image_code_client != image_code_server.decode():
            return JsonResponse({"code": "", "errmsg": '图形验证码输入有误'})
        # 生成短信验证码：生成6位数验证码
        sms_code = "%06d" % random.randint(0, 999999)
        # 保存短信验证码
        redis_conn.setex("sms_" % mobile, 300, sms_code)
        # 发送短信验证码
        CCP().send_message(1, mobile, (sms_code, 5))
        # 响应结果
        return JsonResponse({"code": "0", "errmsg": '发送短信验证码输入成功'})

优化短信验证码后端逻辑，将一些常量定义在另一文件中

短信验证码前端逻辑实现

       check_sms_code() {
            if (this.sms_code.length != 6) {
                this.error_sms_code_message = '请填写短信验证码';
                this.error_sms_code = true;
            } else {
                this.error_sms_code = false;
            }
        },
		// 发送短信验证码

			this.check_mobile();
			this.check_image_code();

			}

			// 向后端接口发送请求，让后端发送短信验证码
			let url = '/sms_codes/' + this.mobile + '/?image_code=' + this.image_code+'&uuid='+ this.uuid;
			axios.get(url, {
				responseType: 'json'
			})
				.then(response => {
					// 表示后端发送短信成功
					if (response.data.code == '0') {
						// 倒计时60秒
						let num = 60;
						let t = setInterval(() => {
							if (num == 1) {

							this.error_image_code_message = response.data.errmsg;
							this.error_image_code = true;
                        } else { // 4002
							this.error_sms_code_message = response.data.errmsg;
							this.error_sms_code = true;
						}
						this.sending_flag = false;
					}
				})
				.catch(error => {
					console.log(error.response);
					this.sending_flag = false;

		},
        // 校验用户名
        check_username() {
            let re = /^[a-zA-Z0-9_-]{5,20}$/;
            if (re.test(this.username)) {

            if (this.error_name == false) {

                axios.get(url, {
                    responseType: 'json'
                })
                    .then(response => {
                        if (response.data.count == 1) {

                            this.error_name = true;
                        } else {

                        }
                    })
                    .catch(error => {
                        console.log(error.response);
                    })
            }
        },
