未完成
初级参考 完整示例代码供参考，建议自己理解后重新输入 
def solve():

        (429, 'RATE_LIMIT', 'Upload rate limit exceeded', {'retry_after':5}),
        (503, 'SERVICE_UNAVAILABLE', 'timeseries_db circuit open', None),
    ]
    for code,ec,msg,details in cases:
        r = error_response(code, ec, msg, details)
        print(f"HTTP {code}: {json.dumps(r, ensure_ascii=False)}")

示例

输入
solve()
期望输出
HTTP 404: {"code": 404, "error": {"code": "DEVICE_NOT_FOUND", "message": "Device DEV099 not found"}}
HTTP 400: {"code": 400, "error": {"code": "MISSING_FIELD", "message": "timestamp is required", "details": {"field": "timestamp"}}}
HTTP 429: {"code": 429, "error": {"code": "RATE_LIMIT", "message": "Upload rate limit exceeded", "details": {"retry_after": 5}}}
HTTP 503: {"code": 503, "error": {"code": "SERVICE_UNAVAILABLE", "message": "timeseries_db circuit open"}}
