Facebook Messenger curl 请求 returns <Response [400]>

Question

我是 Messenger API 的新手，我想使用 curl post 请求发送消息，这是我的代码：

import requests

ACCESS_TOKEN = an Active access token

fb_url = "https://graph.facebook.com/v10.0/me/messages"
data = {
'recipient': '{"id":4098757906843152}',
"message": {
"text": "hello, world!"
},
"messaging_type": "MESSAGE_TAG",
"tag": "ACCOUNT_UPDATE"
}

params = {'access_token': ACCESS_TOKEN}
resp = requests.post(fb_url, params=params, data=data)
print(resp)

不幸的是，我收到了这条消息 任何帮助将不胜感激

Answer 1

您需要将 data 更改为 json。 参见

Starting with Requests version 2.4.2, you can use the json= parameter (which takes a dictionary) instead of data= (which takes a string) in the call

import requests

ACCESS_TOKEN = '<access_token>'

fb_url = 'https://graph.facebook.com/v10.0/me/messages'
data = {
    'recipient': '{"id":<psid>}',
    "message": {
    "text": "hello, world!"
    }
}
params = {'access_token': ACCESS_TOKEN}

resp = requests.post(fb_url, json=data, params=params)
print(resp)
