《Flask入门》第四章：一块宝藏，如何白嫖pythonanywhere制作爆款网站
想要部署网站从来都不是一个简单的工程，也不是一个传统的项目，需要人力成本和物力成本。最基本的物力域名，服务器等…并且坑也不少，好在我年初就踩完了.因为不可抗力，我的云服务器到期了.所以这期讲讲如何pythoanywhere这种国外的高质量免费服务轻松构建网站.
优点
-
支持多类型框架部署：flask,django等
-
支持多python版本
-
一键强制部署https（免证书）
-
提供简短的子域名(name.pythonanywhere.com)
-
免费提供数据库服务
-
共512M个人存储空间
-
没有流量限制，访问速度也不错
缺点
-
不能自定义Cname到自己的域名（需要会员）
-
不允许发送Socket（无法使用flask_socketio，发送Email等）
-
尴尬的调试和错误日志
-
每三个月要求登入，否则删除网站
-
无法对其他网站进行GET或POST
-
在路径方面十分尴尬
pythonanywhere算良心，按照自己的需求就ok了
开工
网址：https://www.pythonanywhere.com/
提示：不建议在cloud上调试，Pythonanywhere的调试方法也一样蛋疼

哈，注册是轻车熟路，用户名是网站前缀.
Pythonanywhere的服务可以说是一个虚拟主机，你可以在512M的空间内创建文件(linux路径)，可以创建终端，运行py程序或者执行cmd命令，例如git clone.
打开Webs app标签页，新建网站，点击flask，把路径简单修改下，如/home/your-name/your-project/app.py，建议project名称与项目的git仓库相同.
新建成功并运行后，访问your-name.pythonanywhere.com，就可以看到默认界面了.
用Git上传自己的项目
在默认路径打开一个终端，直接git clone即可，项目名称与直接的project路径相同，运行文件为app.py，然后回到webs app中点击Reload yourname.pythonanywhere.com即可，如果访问运行失败或者500，在webs app中下拉找到错误日志查看即可.
防止踩坑坑
使用pip安装使用–user
如果按普通方式安装，如
1 | pip install buildapi |
会以下报错
