Discord机器人调用Gemini API时遭遇401未授权错误的解决咨询

核心问题分析 #

日志明确返回UNAUTHENTICATED错误，说明当前配置的凭证无法通过Google API身份校验，结合你提到的凭证格式困惑，问题集中在凭证类型匹配和配置正确性上。

分步解决方案 #

1. 确认OpenClaw所需的凭证类型 #

Google Generative AI API支持两种凭证方式：

• API密钥：格式以AIza开头（注意是AIza，不是你提到的Aiza），适用于服务器端无用户身份的调用场景。
• OAuth 2.0令牌：用于需要用户授权的场景，比如访问用户私有数据。

OpenClaw集成Gemini时，大概率要求使用API密钥而非OAuth令牌。你遇到的系统提示可能是拼写误差，正确的Gemini API密钥前缀是AIza，AQ开头的凭证属于其他Google服务，不适用此处。

2. 重新生成并验证API密钥 #

• 登录Google Cloud Console，进入你的项目。
• 导航到「API和服务」→「凭据」。
• 点击「创建凭据」→「API密钥」，生成新的密钥（确保前缀为AIza）。
• 验证密钥权限：在「API和服务」→「已启用的API和服务」中，确认「Generative Language API」已启用；同时检查API密钥是否设置了IP限制或访问限制，测试阶段可暂时取消限制。

3. 检查OpenClaw的凭证配置 #

• 找到OpenClaw中配置Google Gemini的入口，确保填入的是刚生成的AIza开头的API密钥，而非其他类型凭证。
• 确认配置字段名正确（比如GOOGLE_API_KEY），避免填错位置。

4. 排查其他潜在问题 #

• 确认你的Google Cloud项目未欠费，Gemini API配额未耗尽。
• 检查机器人服务器网络环境，确保能正常访问Google API端点（无防火墙或代理拦截）。
