2. 🎯 原因分析
InvokeModelWithResponseStream接口发送了超出API要求的额外输入参数，导致验证失败。InvokeModelWithResponseStream操作时，请求参数不符合接口规范。3. 💡 解决方案
检查调用
InvokeModelWithResponseStream的代码，确保请求参数完全符合Bedrock官方文档要求。以下是符合规范的基础请求示例（Python boto3）：import boto3
bedrock = boto3.client('bedrock-runtime', region_name='your-region')
# 严格按照Bedrock文档定义的参数结构
request_body = {
"modelId": "your-model-id", # 必填：模型ID
"inferenceConfig": {
"temperature": 0.5, # 可选：推理配置，按需添加
"maxTokens": 1000
},
"messages": [ # 核心消息参数，仅添加接口要求的字段
{
"role": "user",
"content": "请帮我写一篇文章"
}
]
# 删除所有接口未定义的额外参数（如自定义字段、多余的headers、无效的嵌套结构等）
}
try:
response = bedrock.invoke_model_with_response_stream(
ModelId=request_body["modelId"],
Body=json.dumps(request_body).encode('utf-8')
)
except bedrock.exceptions.ValidationException as e:
print("请求参数异常：", e)
