0.效果展示
1.思路总结
1）房屋详情页面开始加载时，detail.js首先通过定义的函数（重点：document.location.search），截取需要向后端取得详情页面的house_id；
2）后端经过逻辑处理，首先向redis中获取相应房屋的具体信息，若redis中不存在，则向数据库查询，返回给前端detail.js；
接下来，detail.js分两部分对前端页面进行渲染；
效果如下：
3）同时判断当前用户是否为房东，如果不为房东，则想用户展示“即刻预订”按钮。
2.后端接口
houses.py相关接口：
@api.route("/houses/<int:house_id>", methods=["GET"])
def get_house_detail(house_id):"""获取房屋详情"""# 前端在房屋详情页面展示时，如果浏览页面的用户不是该房屋的房东，则展示预定按钮，否则不展示，# 所以需要后端返回登录用户的user_id# 尝试获取用户登录的信息，若登录，则返回给前端登录用户的user_id，否则返回user_id=-1user_id = session.get("user_id", "-1")# 校验参数if not house_id:return jsonify(errno=RET.PARAMERR, errmsg="参数缺失")# 先从redis缓存中获取信息try:ret = redis_store.get("house_info_%s" % house_id)except Exception as e:current_app.logger.error(e)ret = Noneif ret:current_app.logger.info("hit house info redis")return '{"errno":"0", "errmsg":"OK", "data":{"user_id":%s, "house":%s}}' % (user_id, ret), \200, {"Content-Type": "application/json"}# 查询数据库try:house = House.query.get(house_id)except Exception as e:current_app.logger.error(e)return jsonify(errno=RET.DBERR, errmsg="查询数据失败")if not house:return jsonify(errno=RET.NODATA, errmsg="房屋不存在")# 将房屋对象数据转换为字典try:house_data = house.to_full_dict()except Exception as e:current_app.logger.error(e)return jsonify(errno=RET.DATAERR, errmsg="数据出错")# 存入到redis中json_house = json.dumps(house_data)try:redis_store.setex("house_info_%s" % house_id, constants.HOUSE_DETAIL_REDIS_EXPIRE_SECOND, json_house)except Exception as e:current_app.logger.error(e)resp = '{"errno":"0", "errmsg":"OK", "data":{"user_id":%s, "house":%s}}' % (user_id, json_house), \200, {"Content-Type": "application/json"}return resp
3.前端js
detail.js
function hrefBack() {history.go(-1);
}// 解析提取url中的查询字符串参数
function decodeQuery(){var search = decodeURI(document.location.search);return search.replace(/(^\?)/, '').split('&').reduce(function(result, item){values = item.split('=');result[values[0]] = values[1];return result;}, {});
}$(document).ready(function(){// 获取详情页面要展示的房屋编号var queryData = decodeQuery();var houseId = queryData["id"];// 获取该房屋的详细信息$.get("/api/v1.0/houses/" + houseId, function(resp){if ("0" == resp.errno) {$(".swiper-container").html(template("house-image-tmpl", {img_urls:resp.data.house.img_urls, price:resp.data.house.price}));$(".detail-con").html(template("house-detail-tmpl", {house:resp.data.house}));// resp.user_id为访问页面用户,resp.data.user_id为房东if (resp.data.user_id != resp.data.house.user_id) {$(".book-house").attr("href", "/booking.html?hid="+resp.data.house.hid);$(".book-house").show();}var mySwiper = new Swiper ('.swiper-container', {loop: true,autoplay: 2000,autoplayDisableOnInteraction: false,pagination: '.swiper-pagination',paginationType: 'fraction'});}})
})
