1.思路總結

1）房屋詳情頁面開始加載時，detail.js首先通過定義的函數（重點：document.location.search），截取需要向后端取得詳情頁面的house_id；

2）后端經過邏輯處理，首先向redis中獲取相應房屋的具體信息，若redis中不存在，則向數據庫查詢，返回給前端detail.js；
接下來，detail.js分兩部分對前端頁面進行渲染；
效果如下：

3）同時判斷當前用戶是否為房東，如果不為房東，則想用戶展示“即刻預訂”按鈕。

2.后端接口

houses.py相關接口：

@api.route("/houses/<int:house_id>", methods=["GET"]) def get_house_detail(house_id):"""獲取房屋詳情"""# 前端在房屋詳情頁面展示時，如果瀏覽頁面的用戶不是該房屋的房東，則展示預定按鈕，否則不展示，# 所以需要后端返回登錄用戶的user_id# 嘗試獲取用戶登錄的信息，若登錄，則返回給前端登錄用戶的user_id，否則返回user_id=-1user_id = session.get("user_id", "-1")# 校驗參數if not house_id:return jsonify(errno=RET.PARAMERR, errmsg="參數缺失")# 先從redis緩存中獲取信息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"}# 查詢數據庫try:house = House.query.get(house_id)except Exception as e:current_app.logger.error(e)return jsonify(errno=RET.DBERR, errmsg="查詢數據失敗")if not house:return jsonify(errno=RET.NODATA, errmsg="房屋不存在")# 將房屋對象數據轉換為字典try:house_data = house.to_full_dict()except Exception as e:current_app.logger.error(e)return jsonify(errno=RET.DATAERR, errmsg="數據出錯")# 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
