我正在尝试关注快速入门Facebook Messenger Bot代码(可在此处找到:https://developers.facebook.com/docs/messenger-platform/quickstart)
我收到了这个错误:
{“error”:{“message”:“(#100)param收件人必须为非空。”,“type”:“OAuthException”,“code”:100,“fbtrace_id”:“ALtKsX4nJtX”} }
有什么想法吗?好像我正在回复正确的回复,但出于某种原因Facebook不接受它?感谢
代码如下(python / appengine):
import webapp2
import json
import urllib
from google.appengine.api import urlfetch
class MainHandler(webapp2.RequestHandler):
print "hello"
FB_MESSENGER_ACCESS_TOKEN = ""
def respond_FB(sender_id, text):
json_data = {
"recipient": {"id": sender_id},
"message": {"text": text + " to you!"}
}
url = "https://graph.facebook.com/v2.6/me/messages?access_token="+FB_MESSENGER_ACCESS_TOKEN
print("json_data", json_data)
data = urllib.urlencode(json_data)
response = urlfetch.fetch(url = url, payload = data, method = urlfetch.POST, headers = {"Content-Type": "application/json"})
print(response.content)
class FacebookMessenger(webapp2.RequestHandler):
def get(self):
if (self.request.get("hub.verify_token") == 'tomstoken'):
return self.response.write(self.request.get("hub.challenge"))
return self.response.write('Error, wrong validation token')
def post(self):
body = self.request.body
messaging_events = json.loads(body.decode("utf-8"))
sender_id = messaging_events["entry"][0]["messaging"][0]["sender"]["id"]
message = messaging_events["entry"][0]["messaging"][0]["message"]["text"]
respond_FB(sender_id, message)
return self.response.write('Received.')
app = webapp2.WSGIApplication([
('/', MainHandler),
('/webhook*', FacebookMessenger)
], debug=True)
答案 0 :(得分:1)
我刚刚使用您的函数requests
进行了测试,因为我没有谷歌应用引擎api所以我使用了response = requests.post(url, json=data)
data
如果json_data
替换为 json_data
,则一切顺利
不知道为什么你需要编码gcloud
,这不是网址
