Question

我正在尝试使用 API 获取场地列表 https://indoor-discovery.venue.maps.api.here.com/discovery/v2?app_id=XXXXXXXXXXXXXXXXXXXX&app_code=XXXXXXXXXXXXXXXXXXXX&at=31.2403,74.6354,8.6291,77.5743

"at"参数几乎覆盖全国。但结果总是返回

{
    "hostname": "ip-10-13-214-44",
    "type": "venues",
    "status": {
        "code": "OK",
        "reason": "DISCOVERY_SUCCESSFULL"
    },
    "results": {
        "items": []
    }
}

Answer 1

边界框的最大值为 100 公里 x 100 公里。如果您在较小的区域内搜索，您将在列表中获得一些结果。这是金奈的报道之一：
