2.后端接口

orders.py部分接口：

@api.route("/orders/<int:order_id>/status", methods=["PUT"])
@login_required
def accept_reject_order(order_id):"""接单、拒单"""user_id = g.user_id# 获取参数req_data = request.get_json()if not req_data:return jsonify(errno=RET.PARAMERR, errmsg="参数错误")# action参数表明客户端请求的是接单还是拒单的行为action = req_data.get("action")if action not in ("accept", "reject"):return jsonify(errno=RET.PARAMERR, errmsg="参数错误")try:# 根据订单号查询订单，并且要求订单处于等待接单状态order = Order.query.filter(Order.id == order_id, Order.status == "WAIT_ACCEPT").first()house = order.houseexcept Exception as e:current_app.logger.error(e)return jsonify(errno=RET.DBERR, errmsg="无法获取订单数据")# 确保房东只能修改属于自己房子的订单if not order or house.user_id != user_id:return jsonify(errno=RET.REQERR, errmsg="操作无效")if action == "accept":# 接单，将订单状态设置为等待评论order.status = "WAIT_PAYMENT"elif action == "reject":# 拒单，要求用户传递拒单原因reason = req_data.get("reason")if not reason:return jsonify(errno=RET.PARAMERR, errmsg="参数错误")order.status = "REJECTED"order.comment = reasontry:db.session.add(order)db.session.commit()except Exception as e:current_app.logger.error(e)db.session.rollback()return jsonify(errno=RET.DBERR, errmsg="操作失败")return jsonify(errno=RET.OK, errmsg="OK")

lorder.js

//模态框居中的控制
function centerModals(){$('.modal').each(function(i){   //遍历每一个模态框var $clone = $(this).clone().css('display', 'block').appendTo('body');    var top = Math.round(($clone.height() - $clone.find('.modal-content').height()) / 2);top = top > 0 ? top : 0;$clone.remove();$(this).find('.modal-content').css("margin-top", top-30);  //修正原先已经有的30个像素});
}function getCookie(name) {var r = document.cookie.match("\\b" + name + "=([^;]*)\\b");return r ? r[1] : undefined;
}$(document).ready(function(){$('.modal').on('show.bs.modal', centerModals);      //当模态框出现的时候$(window).on('resize', centerModals);// 查询房东的订单$.get("/api/v1.0/user/orders?role=landlord", function(resp){if ("0" == resp.errno) {$(".orders-list").html(template("orders-list-tmpl", {orders:resp.data.orders}));$(".order-accept").on("click", function(){var orderId = $(this).parents("li").attr("order-id");$(".modal-accept").attr("order-id", orderId);});// 接单处理$(".modal-accept").on("click", function(){var orderId = $(this).attr("order-id");$.ajax({url:"/api/v1.0/orders/"+orderId+"/status",type:"PUT",data:'{"action":"accept"}',contentType:"application/json",dataType:"json",headers:{"X-CSRFTOKEN":getCookie("csrf_token"),},success:function (resp) {if ("4101" == resp.errno) {location.href = "/login.html";} else if ("0" == resp.errno) {$(".orders-list>li[order-id="+ orderId +"]>div.order-content>div.order-text>ul li:eq(4)>span").html("已接单");$("ul.orders-list>li[order-id="+ orderId +"]>div.order-title>div.order-operate").hide();$("#accept-modal").modal("hide");}}})});$(".order-reject").on("click", function(){var orderId = $(this).parents("li").attr("order-id");$(".modal-reject").attr("order-id", orderId);});// 处理拒单$(".modal-reject").on("click", function(){var orderId = $(this).attr("order-id");var reject_reason = $("#reject-reason").val();if (!reject_reason) return;var data = {action: "reject",reason:reject_reason};$.ajax({url:"/api/v1.0/orders/"+orderId+"/status",type:"PUT",data:JSON.stringify(data),contentType:"application/json",headers: {"X-CSRFTOKEN":getCookie("csrf_token")},dataType:"json",success:function (resp) {if ("4101" == resp.errno) {location.href = "/login.html";} else if ("0" == resp.errno) {$(".orders-list>li[order-id="+ orderId +"]>div.order-content>div.order-text>ul li:eq(4)>span").html("已拒单");$("ul.orders-list>li[order-id="+ orderId +"]>div.order-title>div.order-operate").hide();$("#reject-modal").modal("hide");}}});})}});
