很久之前就在别的服务器上搭建过Flask服务器。
现在要在一台CentOS中搭建Flask服务器。
搭建Flask服务器之前，先去找虚拟环境。
之前知道有个virtual env，貌似还算好用，但是也是有点点麻烦的说。
前不久听说有个更好的，用于虚拟环境的，去找找。
然后就是去：

去用：

知道了，远端服务器中，并没有安装pipenv。
然后接着去开发Flask的内部接口：
【已解决】Flask中实现rest的api去返回典型格式的json数据
然后接着再去：
【已解决】Flask中获取REST API接口的传递进来的参数
再去搞清楚如何添加log：
然后再去尝试连接远程的MongoDB，去读取需要的数据:
【已解决】Flask中连接远程MongoDB数据库的gridfs并返回查询到的文件数据
接着再去想办法，把得到的mongo中girdfs的文件数据，想办法生成绝对的url路径：
【已解决】Flask中Mongo的GridFS数据如何保存为绝对路径的下载文件地址
然后就先去：
