選擇觸發(fā)器，將自己的域名執(zhí)行worker（目前國(guó)內(nèi)國(guó)內(nèi)墻了worker的域名，但是沒有墻IP，所以將自己的域名指向worker的ip）。添加自定義域。

配置完后，可以嘗試下ping自己的域名，此時(shí)的ip應(yīng)該就是指向了CloudFlare。

2、替換官方域名api.openai.com為自身代理域名

import openai
import os

openai.api_base = "https://自己的域名/v1"

openai.api_key = ('自己的key')
model_engine_id = "text-davinci-002"

prompt = "幫我生成一封郵件，約定下周一的見面時(shí)間和地點(diǎn)"
completions = openai.Completion.create(
engine=model_engine_id,
prompt=prompt,
max_tokens=300,
)

message = completions.choices[0].text.strip()
print(openai.api_base)
print(message)

執(zhí)行結(jié)果：

標(biāo)簽：openaichatgpt代理apiai
