在flask中可以像go和angular那样使用页面模版(template)，可以将HTML页面显示进行模版化，通过参数传递与页面进行数据交互。
概要信息
事前准备：flask
liumiaocn:flask liumiao$ which flask/usr/local/bin/flaskliumiaocn:flask liumiao$ flask --versionFlask 1.0.2Python 2.7.10 (default, Jul 15 2017, 17:16:57) [GCC 4.2.1 Compatible Apple LLVM 9.0.0 (clang-900.0.31)]liumiaocn:flask liumiao$
代码示例：嵌入式的HTML模版
像Angular一样，我们可以在flask中写前端的页面，python代码中混杂着HTML代码，在这里将前面的HelloWorld示例进行简单的修改，将显示的Hello World加上的设置。
代码示例
liumiaocn:flask liumiao$ cat flask_1.py #!/usr/bin/pythonfrom flask import Flaskapp = Flask(__name__)@app.route("/")def hello(): return "<h1>Hello World!</h1>"if __name__ == "__main__": app.debug=True app.run(host='0.0.0.0',port=7000)liumiaocn:flask liumiao$执行&确认
在HelloWorld示例中我们提到有两种方式启动flask的微服务进程，这里再添加一种，添加#!/usr/bin/python之后，同时对此文件添加可执行权限比如755，即可使用.启动
liumiaocn:flask liumiao$ chmod 755 flask_1.py liumiaocn:flask liumiao$ ./flask_1.py * Serving Flask app "flask_1" (lazy loading) * Environment: production WARNING: Do not use the development server in a production environment. Use a production WSGI server instead. * Debug mode: on * Running on http://0.0.0.0:7000/ (Press CTRL+C to quit) * Restarting with stat * Debugger is active! * Debugger PIN: 131-533-062
通过curl进行结果确认：
liumiaocn:flask liumiao$ curl http://localhost:7000<h1>Hello World!</h1>liumiaocn:flask liumiao$
页面确认
代码示例
上面的示例过于简单，写一个简单的完整的页面来确认一下
liumiaocn:flask liumiao$ cat flask_1.py #!/usr/bin/pythonfrom flask import Flaskapp = Flask(__name__)@app.route("/")def hello(): return '<!DOCTYPE html> /<html> /<head> /<meta charset="utf-8"> /<title>Hello</title> /</head> /<body>/<h1>Hello World!</h1> /</body>/</html>'if __name__ == "__main__": app.debug=True app.run(host='0.0.0.0',port=7000)liumiaocn:flask liumiao$执行&确认
通过curl可以确认页面范围信息
liumiaocn:flask liumiao$ ./flask_1.py * Serving Flask app "flask_1" (lazy loading) * Environment: production WARNING: Do not use the development server in a production environment. Use a production WSGI server instead. * Debug mode: on * Running on http://0.0.0.0:7000/ (Press CTRL+C to quit) * Restarting with stat * Debugger is active! * Debugger PIN: 131-533-062
