from flask import Flask
app = Flask(__name__)
@app.context_processor
def inject_global_variables():
return {'site_name': 'My Website'}
@app.route('/')
def index():
return render_template('index.html')
模版中使用site_name全局变量
<!DOCTYPE html>
<html>
<head>
<title>{{ site_name }}</title>
</head>
<body>
{% block content %}
{% endblock %}
</body>
</html>
