ChatGPT可以實現(xiàn)chat,生成圖片,識別關(guān)鍵,改錯等等功能，本文簡單介紹如何使用python調(diào)用ChatGPT API 接口。

1. 生成API Key

從openai官網(wǎng)網(wǎng)址：https://platform.openai.com/account/api-keys，生成我們的API key：

獲得key后我們就可以調(diào)用API接口了。

2. 安裝openai

使用pip安裝openai庫,命令： pip install openai。

安裝openai庫: pip install openai

3. python代碼調(diào)用API

3.1 主要步驟

# 調(diào)用openai api的步驟
# 1. 安裝openai庫 pip install openai
# 2. 設(shè)置openai的api_key 
# 3. 調(diào)用openai的api
# 4. 參考文檔
# https://platform.openai.com/docs/api-reference/completions/create
# https://platform.openai.com/docs/api-reference/authentication
# https://platform.openai.com/docs/api-reference/completions/create
# https://platform.openai.com/docs/libraries/community-libraries

3.2 代碼示例

API可以實現(xiàn)chat,生成圖片,識別關(guān)鍵,改錯等等功能。下面是主要示例代碼。注意：openai.api_key = "sk-xxxFQ" #要更換成自已的API KEY

#!/usr/local/bin/python3.8
# -*- coding: utf8 -*-
# 調(diào)用openai api的步驟
# 1. 安裝openai庫 pip install openai
# 2. 設(shè)置openai的api_key 
# 3. 調(diào)用openai的api
# 4. 參考文檔

    )
    image_url = response['data'][0]['url']

    model="gpt-3.5-turbo",
    messages=[
        {"role": "user", "content":prompt}

    answer = response.choices[0].message.content
    return answer
# 調(diào)用openai 識別關(guān)鍵詞
