请问下这个问题最后是怎么处理的

对，检查格式

还是有问题的话建议提交工单问一下呢，可能是账户里没钱之类的

不知道你用的什么语言调用 = = 对于Python来讲，accrss_token的取值方法是固定的

import requests

##############
###  参数  ###
##############
API_Key = 【API Key】
Secret_Key = 【Secret Key】

# 第一次 Post 请求，获取access_token
def get_access_token():
    # url
    url = 'https://aip.baidubce.com/oauth/2.0/token'
    # 参数
    params = {
        'grant_type': 'client_credentials',    # 固定值  
        'client_id': API_Key,  
        'client_secret': Secret_Key  
    }
    res = requests.post(url, data=params)
    # 请求成功 返回access_token和expires_in
    # 请求失败 返回error和error_description
    res = res.json()
    access_token = res['access_token']
    return access_token

嘤嘤嘤

是25开头的，因为一直报所以我把代码写到了一起，获取之后立马使用，还是报

你给的值是24.xx开头的吗？确保取值取的对。

是取access_token的值
