I want to using plone to receive to xml message that posted from Wechat server. I define the following browser view to receive message:
class Receive(BrowserView):
def__init__(self,context,request)
self.context = context
self.request = request
def render(self):
from zope import event
import pdb
pdb.set_trace()
from my315ok.wechat.events import ReceiveWechatEvent
data = self.request.form
ev = self.request.environ
robot = BaseRoBot(token="haha018")
try:
rn = robot.check_signature(
data["timestamp"],
data["nonce"],
data["signature"]
)
except:
return self.abort(403)
if ev['REQUEST_METHOD'] =="GET":
# valid request from weixin
if rn:
return data["echostr"]
else:
return self.abort(403)
else:
# normal request form weixin
if not rn:
return self.abort(403)
body = self.request.get['BODY']
message = parse_user_msg(body)
logging.info("Receive message %s" % message)
event.notify(ReceiveWechatEvent(message))
return ""
This is my zcml file:
<configure
xmlns="http://namespaces.zope.org/zope"
xmlns:browser="http://namespaces.zope.org/browser"
i18n_domain="my315ok.wechat">
<browser:page
for="*"
name="send_as_wechat"
class=".send.SendForm"
template="templates/send_page.pt"
permission="zope2.View"
/>
<browser:page
for="*"
name="robot"
class=".receive.Receive"
permission="zope2.View"
/>
</configure>
But when I send text xml message to the view(http://myhost.com/@@robot), encountered the following error:
plone run at debug model,but debug can't enter render funcation.
when I use tcpdump catch plone tcp traffice ,I got the following tcpdump:
the problem look to like post xml request can't been received by plone view.
tcpdump out:

Thanks lot.
I also try to using __call__(self) replace render(self),but still don't work.
By the way, I using a real browser agent to access the http://myhost.com/@@robot,(for example,IE firefox etc.)may enter the render（self) function for debug
Your example code is not consistent. You define a view called "robot" and are using a the class value ".receive.Robot". That doesn't suit to your class definition where the class is called "Receive".
Anyway - suitable to your configure.zcml the content of the receive.py file should be like this:
Accessing the view with your Browser should return the incomfing data.
I am not sure if I understand your last note right: if your code is already working with browser, but not via the Wechat Server - than check your access logs (in general, located at $buildout-home/var/log/instance-Z2.log) if the requests are receiving the plone instance.
Another problem might be, that your need Authentication - but that depends on your setup. Do you see any results in the Wechat environment of the call?
