创建应用用于获取access_token

创建应用成功后,可以获取到API Key和Secret Key

获取access_token

curl 'https://aip.baidubce.com/oauth/2.0/token?grant_type=client_credentials&client_id=【API Key】&client_secret=【Secret Key】'

开通付费服务

api调用是按token(字数)收费的,不开通收费无法使用。

发送对话请求

curl -XPOST 'https://aip.baidubce.com/rpc/2.0/ai_custom/v1/wenxinworkshop/chat/completions?access_token=[步骤一调用接口获取的access_token]' -d '{
   "messages": [
    {"role":"user","content":"介绍一下你自己"}
   ]
}'
