自己没有公网ip接入支付宝
技术是vue+drf
vue–主要看创建订单和修改订单支付状态
balanceCount () {// 结算if(this.addrInfo.length==0){alert("请选择收货地址")}else{createOrder({post_script:this.post_script,address:this.address,signer_name:this.signer_name,signer_mobile:this.signer_mobile,order_mount:this.totalPrice}).then((response)=> {alert('订单创建成功');window.location.href=response.data.alipay_url;updateOrder({"order_id": response.data.id}).then((response)=>{alert("订单修改成功");}).catch(function (error) {console.log(error);});}).catch(function (error) {console.log(error);});
api–只看创建订单和修改订单支付状态
//添加订单export const createOrder = params => {return axios.post(`${local_host}/orders/`, params)}//订单更新export const updateOrder = params => {return axios.post(`${local_host}/check_pay/`, params)}
订单序列化–创建订单时去支付宝支付, 所以在序列化类里要创建个alipay_url
class OrderSerializer(serializers.ModelSerializer):"""订单信息序列化类"""user = serializers.HiddenField(default=serializers.CurrentUserDefault())add_time = serializers.DateTimeField(read_only=True, format="%Y-%m-%d %H:%M:%S")# read_only只返回不提交# write_only只提交不反回pay_status = serializers.CharField(read_only=True)order_sn = serializers.CharField(read_only=True)trade_no = serializers.CharField(read_only=True)# order_mount = serializers.FloatField(read_only=True)pay_time = serializers.DateTimeField(read_only=True)# SerializerMethodField 这是一个只读字段。它通过在附加的序列化器类上调用一个方法来获取其值。它可以用于将任何类型的数据添加到对象的序列化表示中。# read_only 只返回不提交alipay_url = serializers.SerializerMethodField(read_only=True)def get_alipay_url(self, obj):alipay = AliPay(appid="", # 沙箱appid 或 线上appidapp_notify_url=None, # 默认回调url 不写的话这里用None# os.path.dirname(__file__): 获取当前文件所在目录的路径app_private_key_path=os.path.join(os.path.dirname(__file__), "keys/app_private_key.pem"), # 私钥alipay_public_key_path=os.path.join(os.path.dirname(__file__), "keys/alipay_public_key.pem"),# 支付宝的公钥，验证支付宝回传消息使用，不是你自己的公钥,sign_type="RSA2", # RSA 或者 RSA2debug=True # 默认False 沙箱环境把这里设置为True)url = alipay.api_alipay_trade_page_pay(out_trade_no=obj.order_sn, # 订单idtotal_amount=str(obj.order_mount), # 支付总金额(这里用str 它内部自动将它转换成json)subject=obj.order_sn, # 订单标题)return '/gateway.do?' + urldef generate_order_sn(self):"""生成订单号:return:"""from random import Randomrandom_ins = Random()# 当前时间+userid+随机数# 当前时间并且格式化time.strftime("%Y%m%d%H%M%S")# self.request.user.id当前用户的id# random_ins.randint(10, 99)生成两位的随机数order_sn = "%s%s%s" % (time.strftime("%Y%m%d%H%M%S"), self.context["request"].user.id, random_ins.randint(10, 99))return order_sndef validate(self, attrs):print("attrs", attrs)attrs["order_sn"] = self.generate_order_sn()return attrsclass Meta:model = OrderInfofields = "__all__"
订单详情序列化–订单的详情页面点击去支付, 所以在序列化类里要创建个alipay_url
