@app.route()
methods:当前url地址,允许访问的请求方式
@app.route("/info", methods=["GET", "POST"])
def student_info():
stu_id = int(request.args.get("id"))
return f"{stu_id}" # Python3.6的新特性 f"{变量名}"
endpoint:反向生成url地址,默认为视图函数名,导入url_for
from flask import Flask, url_for
app = Flask(__name__)
@app.route("/index",methods=["POST","GET"],endpoint="index_s")
def index():
return url_for("index_s") #index
if __name__ == ‘__main__‘:
app.run(debug=True)
strict_slashes:url地址结尾符"/"的控制,默认为True:结尾不能的"/",False:无论结尾是否有"/"均可以访问
from flask import Flask, url_for
app = Flask(__name__)
#访问地址 /index
@app.route("/index",strict_slashes=True)
def index():
return url_for("index_s")
#访问地址:/login 或 /login/
@app.route("/login",strict_slashes=False)
def login():
return ‘欢迎‘
if __name__ == ‘__main__‘:
app.run(debug=True)
defaults : 视图函数的参数默认值{"nid":1}
from flask import Flask, url_for
app = Flask(__name__)
@app.route("/index", defaults={"nid": 1})
def index(nid):
print(nid)
return "哈喽"
if __name__ == ‘__main__‘:
app.run(debug=True)
redirect_to:url地址重定向,301永久重定向,在进入视图函数之前跳转
from flask import Flask, url_for
app = Flask(__name__)
@app.route("/index", redirect_to="/login")
def index(id):
print(id)
return "光临"
@app.route("/login")
def login():
return ‘欢迎‘
if __name__ == ‘__main__‘:
app.run(debug=True)
动态路由参数
接受文件名,返回文件
<int:id>:只能是数字
from flask import Flask, url_for
app = Flask(__name__)
@app.route("/index/<int:a>",) #访问 http://127.0.0.1:5000/index/1
def index(a):
print(a) # 1
return "光临"
if __name__ == ‘__main__‘:
app.run(debug=True)
<string:str>:可以是数字也可以是字符串
from flask import Flask, url_for
app = Flask(__name__)
@app.route("/index/<string:str>",)
def index(str):
print(str)
return "光临"
if __name__ == ‘__main__‘:
app.run(debug=True)
也可以不用定义类型,默认接受字符串
from flask import Flask, url_for
app = Flask(__name__)
@app.route("/index/<name>",)
def index(name):
print(name)
return "光临"
if __name__ == ‘__main__‘:
app.run(debug=True)
