openai.AuthenticationError: Error code: 401 - {'error': {'message': 'Incorrect API key provided: your-api-key. You can find your API key at https://platform.openai.com/account/api-keys.', 'type': 'invalid_request_error', 'param': None, 'code': 'invalid_api_key'}}

错误翻译
原文： Incorrect API key provided: your-api-key.
译文： 提供的API密钥不正确：your-api-key。
原因分析
报错的核心原因是API密钥配置错误。从错误信息可以看出：
- 使用的是
your-api-key这个占位符值，而不是真实的有效API密钥 - OpenAI API服务返回401认证错误，拒绝访问
- 错误发生在调用
client.images.generate()方法时
解决方案
方法一：设置正确的API密钥
import openai
# 正确设置API密钥（替换your-api-key为真实密钥）
client = openai.OpenAI(api_key="sk-your-actual-api-key-here")
response = client.images.generate(
model="dall-e-3",
prompt="3 picture of orange cat",
size="1024x1024"
)方法二：使用环境变量（推荐）
import os
import openai
# 从环境变量读取API密钥
openai.api_key = os.getenv("OPENAI_API_KEY")
client = openai.OpenAI()
response = client.images.generate(
model="dall-e-3",
prompt="3 picture of orange cat",
size="1024x1024"
)️ 预防措施
# 在终端设置环境变量
export OPENAI_API_KEY="sk-your-actual-api-key"
# 验证API密钥是否有效
try:
client.models.list()
print("API密钥验证成功")
except Exception as e:
print(f"API密钥验证失败: {e}")
注意： 请确保使用正确的模型名称，图像生成应使用 dall-e-3 而非 gemini-3-pro-image-preview。
