這是我的代碼

import requests
import json
url='http://www.placeboworld.cn/oauth/token'
values={"cliend_id":"1109","client_secret":"fc1c890e2e","username":"15790","password":"0894aef469","grant_type":"password"}
headers={"Content-Type": "application/x-www-form-urlencoded"}
jdjd=requests.post(url=url,data=values)
print(jdjd.text)

錯(cuò)誤代碼

{"error":"invalid_client","error_description":"Client credentials were not found in the headers or body"}

請(qǐng)問可能是什么原因呢？
