用户的消息是一个简单的“你好”，这明显属于问候语。根据示例，当用户说“你好”时，意图是greeting，置信度为0.9。这里用户没有提到任何订单相关信息，也没有进行告别，所以排除其他意图。 接下来检查是否有需要提取的实体。由于用户只是打招呼，没有提到订单号、产品名称或问题类型，所以extracted_entities应该是空的。 确认置信度，因为这是典型的问候语，所以置信度较高，设为0.9。分析理由就是用户发送了简单的问候语，没有其他上下文。 最后，按照JSON格式返回结果，确保键名正确，没有语法错误。比如，intent的值是greeting，confidence是0.9，reasoning说明情况，extracted_entities为空对象。 { "intent": "greeting", "confidence":

用户的消息是一个简单的“你好”，这明显属于问候语。根据示例，当用户说“你好”时，意图是greeting，置信度为0.9。这里用户没有提到任何订单相关信息，也没有进行告别，所以排除其他意图。 接下来检查是否有需要提取的实体。由于用户只是打招呼，没有提到订单号、产品名称或问题类型，所以extracted_entities应该是空的。 确认置信度，因为这是典型的问候语，所以置信度较高，设为0.9。分析理由就是用户发送了简单的问候语，没有其他上下文。 最后，按照JSON格式返回结果，确保键名正确，没有语法错误。检查是否遗漏了任何必填字段，如intent、confidence和reasoning。确认所有部分符合要求后，生成最终的JSON响应。 { "intent": "greeting", "confidence": 0.9,
