+
+## 起因
+
+今天（2019-12-23）在东一一楼烧腊窗口恰饭，我点的是鸡排饭，然后我没说要啥汁，那个姐姐（感觉叫阿姨不太对）直接说：番茄是吧。我：？，我挺疑惑的，然后在她把饭递给我的时候问了句：你咋知道的？她：因为你经常吃啊（笑）。
+
+想了下好像也没有经常吃吧，虽然之前高中也有过类似的经历，那是因为吃拉面不要香菜、热干面不要葱、炒面炒粉不要葱，然后吃了一段时间就被老板记住了。
+
+很有趣的一次是吃热干面，老板没抬头看，就调好葱姜蒜芝麻酱准备递给我，然后看到我，说：哎呀，你不要葱，这碗给后面的同学，重新给你下一碗 2333。扯远了，因为挺好奇的，于是就打算把今年这一年的吃饭记录都爬下来康康，我这一年都吃的是啥？
+
+## 数据获取
+
+从 [校园卡服务平台](http://ecard.hust.edu.cn/Default.aspx) 可以查到流水，开始我以为所谓的“导出所有”是把所有记录导出，结果跟“导出当前页流水”是一样的。
+
+所以直接用 Python 写了个爬虫直接把今年（2019）所有月份数据都爬下来，去掉多余的信息，仅保存 *时间*、*价格*、*食堂* 这三项数据，然后存为 CSV 文件。
+

+
+## 数据分析
+
+所以这一年到底吃了啥？下面就见分晓！
+
+首先将这些 csv 文件合并，使用 `pandas` 库很简单，下面就是：
+
+```python
+def merge_all_files():
+    files = glob.glob("csv/*.csv")
+    df = pd.concat([pd.read_csv(file) for file in files])
+    df.to_csv("csv/2019.csv", index=False, encoding='utf-8-sig')
+```
+

+  <summary>2019</summary>
+
+### 2019 数据详情
+
+截止到今天，每个月使用一卡通的消费次数（包括超市和自动售卖机）：
+
+```
+{
+	1: 95,
+	2: 50,
+	3: 142,
+	4: 121,
+	5: 131,
+	6: 111,
+	7: 104,
+	8: 138,

+
+1、各个食堂的食用情况

+
+3、各时间段的食用情况
+
+![](images/hours_2020.png)
+
+4、各个月的食用情况
+
+![](images/consume_times_2020.png)
+
+5、总体概况
+
+在 2020，你连续在 东一二楼大众菜（一） 窗口消费了 4 次，看来你很喜欢这个窗口！
+
+在 2020，你一共消费了 682 次，共花费 3331.35 元！
+

+
+## 如何使用
+
+运行 `ecard.py` 前需要登录拿到 `JSESSIONID` 然后填到 `ecard.py` 对应位置；画图前记得解压字体文件：`SourceHanSansCN-Light.7z`，也可以自定义字体，修改 `utils.py` 中的 `myfont = FontProperties(fname="SourceHanSansCN-Light.otf")` 即可。
+
+```Bash
+git clone [email protected]:taseikyo/hust-ecard-annual.git
+cd hust-ecard-annual
+pip3 install -r requirements.txt
+# 获取数据
+python3 ecard.py
+# 画图
+python3 utils.py
+```
+
+由于校园卡消费记录的是食堂窗口，所以为了提取出食堂我是设了几个食堂关键词：
+
+```
+HALLS = {
+    "东一",
+    "集贤楼",
+    "自助售货机",
+    "西一",
+    "百品屋",
+    "集锦园",
+    "校园网",
+    "图书馆",
+    "东学超市",
+    "东三",
+    "紫荆园",
+    "百景",
+    "喻园",
+}
+```
+
+当然这些肯定是不全的，毕竟有一共三十多个食堂，所以在代码里面不在 `HALLS` 的食堂直接保存。
+
+```Python
+has_found = False
+for hall in HALLS:
+    if row[-1].find(hall) >= 0:
+        has_found = True
+        halls[hall] += 1
+        break
+if not has_found:
+    halls[row[-1]] += 1
+```
