Flask快速入门(5) — 模板渲染

视图函数

from flask import Flask,request,render_template,Markup
app = Flask(__name__)

@app.route('/',endpoint='index')
def index():
    age = 18
    classes = '班级'
    schools = ['s1','s2','s3']
    USER = {
        1: {'name': 'Nick', 'age': 18, 'hobby': ['study', 'swimming']},
        2: {'name': 'Bob', 'age': 19, 'hobby': ['basketball', 'game']},
        3: {'name': 'Link', 'age': 17, 'hobby': ['sing', 'dance']},
        4: {'name': 'Sean', 'age': 20, 'hobby': ['game', 'walking']},
    }
    safe_test = '
测试xss
'
    return render_template('index.html',info=USER,classes=classes,schools=schools,age=age,safe_test=safe_test)

@app.route('/login')
def login():
    return Markup('
我最帅
')  # 

if __name__ == '__main__':
    app.run()

index.html

    
    




    classes: {{ classes }}



{{schools.0}}
{{schools[1]}}
{{schools[:-1]}}


    {% for school in schools %}
    
{{ school }}
    {% endfor%}



{% for key,val in info.items() %}  
    {{ val.name}}
    {{ val['name']}}
    {{ val.get('name')}}
{% endfor %}


{% if age > 10 %}
    
{{age}}
{% endif %}
    
无safe时，不解析标签 {{safe_test}}


有safe时，解析标签{{safe_test|safe}}

与django不同的是，在flask中模板渲染可以用[],()之类的，执行函数，传参数。

from flask import Flask,render_template,Markup,jsonify,make_response
app = Flask(__name__)

def func1(arg):
    return Markup("" %(arg,))
@app.route('/')
def index():
    return render_template('index.html',ff = func1)  # 传了函数过去

if __name__ == '__main__':
    app.run()

    
    


    
    {{ff('六五')}}  
    {{ff('六五')|safe}}

注意：

1.Markup等价django的mark_safe

2.用于模板的extends,include与django中的一模一样
