flask路由（2）

注册路由方式有三种。

具体如下：app.route

from flask import Flask

app = Flask(__name__)


@app.route('/')
def hello_world():
    return 'Hello World!'
@app.route("/log/<user_name>")
def mylog(user_name):
    return "welcome to my home %s" %(user_name)


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

app.add_url_rule

from flask import Flask

app = Flask(__name__)


@app.route('/')
def hello_world():
    return 'Hello World!'
def log():
    return "welcome to my home"
#此处的/log/的最后一个“/”要写上。这使得他能够匹配有/或者无的两种情况

app.add_url_rule(rule="/log/",view_func=log)

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

蓝图：访问http://127.0.0.1:5000/imooc/my/

from flask import Flask,Blueprint

app = Flask(__name__)

index_page = Blueprint("index_page",__name__)

@index_page.route("/my/")

def index_page_index():
    return "index page"
app.register_blueprint(index_page,url_prefix = "/imooc")

@app.route('/')
def hello_world():
    return 'Hello World!'


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

结构分层处理【在大项目中使用】

# -*- coding: utf-8 -*-
from flask import Flask,Blueprint
'''
post/index 列表
post/info 详情
post/set 添加|编辑
post/ops 操作（删除|恢复）
'''

index_page = Blueprint( "index_page",__name__ )

@index_page.route( "/" )
def index_page_index():
    return "index page"


@index_page.route( "/me/" )
def hello():
    return "hello ,I Love Imooc"

from flask import Flask
from comm import index_page

app = Flask(__name__)

app.register_blueprint( index_page,url_prefix = "/imooc" )
if __name__ == "__main__":
    app.run()

post&get&upload文件处理

from flask import Flask
from comm import index_page

app = Flask(__name__)

app.register_blueprint( index_page,url_prefix = "/imooc" )
if __name__ == "__main__":
    app.run()

# -*- coding: utf-8 -*-
from flask import Flask,Blueprint,request

index_page = Blueprint( "index_page",__name__ )

@index_page.route( "/" )
def index_page_index():
    return "index page"

@index_page.route( "/me/" )
def hello():
    return "hello ,I Love Imooc"

@index_page.route("/get/")
def get():
    #获取request的值
    req = request.values
    #等同：var_a = request.args.get( "a","i love imooc" )
    var_a = req['a'] if "a" in req else "i love imooc"
    return "request:%s,params:%s,var_a:%s"%(request.method,request.args,var_a)

@index_page.route("/post/",methods = ['POST'])
def post():
    req = request.values
    var_a = req['a'] if "a" in req else "i love imooc"
    return "request:%s,params:%s,var_a:%s"%( request.method,request.args,var_a )

@index_page.route("/upload/",methods = [ "POST" ])
def upload():
    f = request.files['file'] if "file" in request.files else None
    return "request:%s,params:%s,file:%s"%(request.method,request.files,f )
