如何使用Blueprint在Flask中正确声明子域？

Question

我一直在关注这篇文章中提供的方法：     https://stackoverflow.com/questions/12167729/flask-subdomains-with-blueprint-getting-404

以下是我的相关代码：

__初始化__。PY

from flask import Flask, render_template

app = Flask(__name__, static_url_path="", static_folder="static"
import myApp.views

views.py

from flask import Flask, render_template, request, Blueprint
from myApp import app

app.config['SERVER_NAME'] = 'myapp.com'
app.url_map.default_subdomain = "www"

@app.route("/")
def index():
    return "This is index page."

test = Blueprint('test', 'test', subdomain='test')

@test.route("/")
def testindex():
    return "This is test index page."

app.register_blueprint(test)

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

使用这种方法，我可以获得子域名＆＃39; test＆＃39;和＆＃39; www＆＃39;工作，但现在我无法通过IP地址访问我的网站。

任何对正确方向的指导都将不胜感激！
