[英]Calling the same endpoint more than once in Cherrypy
I have created a simple web server with Cherrypy
and my resources are only available the first time I make the call. 我使用
Cherrypy
创建了一个简单的Web服务器,并且只有在我第一次拨打电话时才能使用我的资源。
For example: 例如:
When I put the following on the browser http://127.0.0.1:8080/catalog/about
- it displays the Cherrypy
version as {"version": "18.1.1"}
- which is correct. 当我在浏览器
http://127.0.0.1:8080/catalog/about
上放置以下内容时-它将Cherrypy
版本显示为{"version": "18.1.1"}
-是正确的。
However, If I hit enter one more time I get the following " 404 Not Found " 但是,如果我再按一次Enter键,则会显示以下“ 404 Not Found ”
Is this a safety feature and how do I change this settings? 这是一项安全功能,如何更改此设置? I don't understand
我不明白
server.py: server.py:
import os
import os.path
import random
import string
import json
import cherrypy
from controller import Catalog
class Server(object):
@cherrypy.expose
def index(self):
return open('../cococlient/build/index.html')
def cors():
cherrypy.response.headers["Access-Control-Allow-Origin"] = "*"
if __name__ == '__main__':
conf = {
'/': {
'tools.staticdir.root': os.path.abspath(os.getcwd())
},
'/catalog': {
'tools.CORS.on': True,
'tools.response_headers.on': True
},
'/static': {
'tools.staticdir.on': True,
'tools.staticdir.dir': '../cococlient/build/static'
}
}
server = Server()
server.catalog = Catalog()
cherrypy.tools.CORS = cherrypy.Tool('before_handler', cors)
# cherrypy.tree.mount(server, '/', conf)
# cherrypy.engine.start()
# cherrypy.engine.block()
cherrypy.quickstart(server, '/', conf)
controller.py: controller.py:
import cherrypy
class Catalog(object):
@cherrypy.expose
@cherrypy.tools.json_out()
def about(self):
self.about = {
"version": cherrypy.__version__
}
return self.about
Found the issue - the problem is that I am using the same name for the method and variable inside. 找到了问题-问题是我在内部使用相同的名称作为方法和变量。 I am used to Java where I have no such issues.
我已经习惯了Java,而我却没有这类问题。
So, instead of 所以,代替
@cherrypy.expose
@cherrypy.tools.json_out()
def about(self):
self.about = {
"version": cherrypy.__version__
}
return self.about
change to 改成
@cherrypy.expose
@cherrypy.tools.json_out()
def about(self):
self.someOtherName = {
"version": cherrypy.__version__
}
return self.someOtherName
Success! 成功!
