应用程序的所有路由都存储在
app.url_map的实例上
werkzeug.routing.Map。你可以
Rule使用以下
iter_rules方法遍历实例：
from flask import Flask, url_forapp = Flask(__name__)def has_no_empty_params(rule): defaults = rule.defaults if rule.defaults is not None else () arguments = rule.arguments if rule.arguments is not None else () return len(defaults) >= len(arguments)@app.route("/site-map")def site_map(): links = [] for rule in app.url_map.iter_rules(): # Filter out rules we can't navigate to in a browser # and rules that require parameters if "GET" in rule.methods and has_no_empty_params(rule): url = url_for(rule.endpoint, **(rule.defaults or {})) links.append((url, rule.endpoint)) # links is now a list of url, endpoint tuples
