全局参数配置-Flask

###直接定义
```python
from flask import Flask
app=Flask(__name__)

app.config['WEB_NAME']='哈哈哈网'
@app.route('/')
def hello_word():
    print(app.config['WEB_NAME'])
    print(app.config)
    return 'hello_word!'

if __name__=='__main__':
    app.run(debug=True,host='0.0.0.0',port=6666)
```
###config.py
```python
TEST=666
NAME='张三'
PHONE=13312341234
###建议大写，也可以是txt文件等格式
```

###import导入文件
```python
from flask import Flask
import config
app=Flask(__name__)

app.config['WEB_NAME']='哈哈哈网'
app.config.from_object(config)  #导入配置文件

@app.route('/')
def hello_word():
    print(app.config['WEB_NAME'])
    print(app.config)
    return 'hello_word!'

if __name__=='__main__':
    app.run(debug=True,host='0.0.0.0',port=6666)
```

###程序导入文件
```python
from flask import Flask
app=Flask(__name__)

app.config['WEB_NAME']='哈哈哈网'
app.config.from_pyfile('config.py',silent=True)  #加载文件 silent 参数这样加载的静态文件没有被找到时不会出错
@app.route('/')
def hello_word():
    print(app.config['WEB_NAME'])
    print(app.config)
    return 'hello_word!'

if __name__=='__main__':
    app.run(debug=True,host='0.0.0.0',port=6666)
```
