🤖 AI解决方案

错误分析报告

1. 错误翻译

原文："messages length only support 1"
译文："消息长度仅支持1"

2. 原因分析

根本原因: API接口要求消息数组长度必须为1，但当前代码传递了多个消息
错误位置: 在处理AI服务提供商的API调用时，ModernAiProvider.modernCompletions方法中
上下文: 这是一个AI服务提供商特定的限制，可能是指某些AI模型只支持单消息输入

3. 解决方案

// 修复方案：确保messages数组长度为1
// 方法1：使用第一条消息
const singleMessage = messages.length > 0 ? [messages[0]] : [];

// 方法2：合并多条消息为单条消息
const combinedMessage = [{
  role: 'user',
  content: messages.map(msg => msg.content).join('\n\n')
}];

// 在ModernAiProvider中使用
await modernCompletions({
  messages: singleMessage, // 或 combinedMessage
  // 其他参数...
});

4. ️ 预防措施

参数验证: 在调用AI服务前验证messages数组长度

   if (messages.length !== 1) {
     throw new Error(`当前AI服务仅支持单条消息，当前消息数: ${messages.length}`);
   }

文档检查: 使用AI服务前务必查阅对应API文档，了解特定的参数限制要求

适配器模式: 实现消息适配器来处理不同服务商的消息格式要求差异

建议: 在代码中添加服务商能力检测逻辑，根据不同的AI服务提供商动态调整消息处理策略。
