Flask的所有路由构造都支持
subdomain关键字参数（这包括对路由变量的支持）。
@app.route("/", subdomain="static")def static_index(): """Flask supports static subdomains This is available at static.your-domain.tld""" return "static.your-domain.tld"@app.route("/dynamic", subdomain="<username>")def username_index(username): """Dynamic subdomains are also supported Try going to user1.your-domain.tld/dynamic""" return username + ".your-domain.tld"
