铜陵seo/上海关键词排名优化怎样

编辑：找出原因，按F12，单击网络，选中“禁用缓存”。

我有一个基本的烧瓶服务器，用来学习d3。问题是chrome给了我一个正在使用的缓存javascript文件example.js。

请求方法：GET

状态代码：200 OK(来自内存缓存)

服务器本身正在发送一个非缓存响应，我可以通过以下直接查看响应：

/static/example.js/静态/example.js

我在application.py中添加了这个以防止缓存。@app.after_request

def add_header(r):

"""

Add headers to both force latest IE rendering engine or Chrome Frame,

and also to cache the rendered page for 10 minutes.

"""

r.headers["Cache-Control"] = "no-cache, no-store, must-revalidate"

r.headers["Pragma"] = "no-cache"

r.headers["Expires"] = "0"

r.headers['Cache-Control'] = 'public, max-age=0'

return r

这是全部代码import os

import re

from flask import Flask, jsonify, render_template, request, url_for

from flask_jsglue import JSGlue

from flask import send_file

# configure application

app = Flask(__name__)

JSGlue(app)

# prevent cached responses

@app.after_request

def add_header(r):

"""

Add headers to both force latest IE rendering engine or Chrome Frame,

and also to cache the rendered page for 10 minutes.

"""

r.headers["Cache-Control"] = "no-cache, no-store, must-revalidate"

r.headers["Pragma"] = "no-cache"

r.headers["Expires"] = "0"

r.headers['Cache-Control'] = 'public, max-age=0'

return r

@app.route("/")

def main(filename):

"""Render file."""

return render_template(filename)

@app.route("/favicon.ico")

def favicon():

filename = 'images/fav.png'

return send_file(filename, mimetype='image/png')

谢谢你的阅读。
