CherryPy 將AJAX應(yīng)用于應(yīng)用程序
2024-01-01 21:26 更新
考慮一個(gè)應(yīng)用程序，它包含一個(gè)名為“media”的文件夾，其中包含index.html和Jquery插件，以及一個(gè)帶有AJAX實(shí)現(xiàn)的文件。 讓我們將文件名稱視為“ajax_app.py”
ajax_app.py
import cherrypy
import webbrowser
import os
import simplejson
import sys
MEDIA_DIR = os.path.join(os.path.abspath("."), u"media")
class AjaxApp(object):
@cherrypy.expose
def index(self):
return open(os.path.join(MEDIA_DIR, u'index.html'))
@cherrypy.expose
def submit(self, name):
cherrypy.response.headers['Content-Type'] = 'application/json'
return simplejson.dumps(dict(title="Hello, %s" % name))
config = {'/media':
{'tools.staticdir.on': True,
'tools.staticdir.dir': MEDIA_DIR,}
}
def open_page():
webbrowser.open("http://127.0.0.1:8080/")
cherrypy.engine.subscribe('start', open_page)
cherrypy.tree.mount(AjaxApp(), '/', config=config)
cherrypy.engine.start()“AjaxApp”類重定向到“index.html”的網(wǎng)頁(yè)，該網(wǎng)頁(yè)包含在媒體文件夾中。
