methods
The method of the current view request supported
from flask import Flask,render_template app = Flask(__name__) @app.route("/login", methods=["GET", "POST"]) def student_info(): return "Hello wWrd "
The default parameters do not write methods only supports GET requests, methods parameter is the way we rewrite the inside, not added
endpoint
Route map - a view function
Import the Flask Flask from, the render_template, the redirect App = the Flask (name__ __) @ app.route ( "/ Login", Methods = [ "the GET", "the POST"], Endpoint = "log") DEF student_info (): return "the Hello wWrd " # is equivalent to / login name takes the individual, where after the view function is used in the direct path can be resolved to an alias / login path this example: @ app.route ( '/ index', Methods = [ ' the GET ',' the POST ']) DEF index (): return the redirect ( "log")
defaults
Once the default parameters have default parameters must exist to receive a parameter variable name parameter must be consistent with the view function defaults
Import the Flask Flask from, the render_template @ app.route ( '/ index', Methods = [ 'the GET', 'the POST'], Defaults = { 'ID': 2}) DEF index (ID): This parameter must be followed by # consistent with the defaults key Print (ID) # 2 return the render_template ( 'the login.html')
strict_slashes
Whether or not strictly follow the routes matching rules "/"
from flask import Flask,render_template,redirect app = Flask(__name__) @app.route("/login", methods=["GET", "POST"],strict_slashes=False) def student_info(): return "Hello wWrd " # 默认遵守严格模式strict_slashes=True
When we request the path on the browser, if the input is below a path then the browser will automatically we add a path separator "/"
strict_slashes = False no matter behind "/" can be matched to
redirect_to
Permanent redirect, and not through the view function
@app.route('/index',methods=['GET', 'POST'],redirect_to='/login') def index(): return render_template('index.html')
Dynamic routing parameters
Add additional parameters in the request path
Import the Flask Flask from, the render_template, the redirect App = the Flask (name__ __) @ app.route ( "/ Login / <args> / <int: NUM>", Methods = [ "the GET", "the POST"],) denotes # int must be an integer def student_info (args, num): # parameter name must be consistent and routing parameters Print (args, NUM) # 2 aaaa return "the Hello Word"
Dynamic parameters <> package
<> can be written as the <int: num> so. Int type argument must be given, or will be error
<> within not write, the default is str
