检索视频的元数据
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
给定有效的地址或 videoID 后，lookupVideoMetadata 方法会返回与给定视频相关联的元数据。响应正文中的元数据可让您确定影像的新鲜度、视频的长度，还提供了一个免费的工作流来确认视频是否存在。
如何使用该 API
通过向此端点传递网址编码的美国邮政地址或 videoId 来调用此端点。
curl -X GET "https://aerialview.googleapis.com/v1/videos:lookupVideoMetadata?key=YOUR_API_KEY&address=POSTAL_ADDRESS"
然后，API 会返回以下两种响应之一：
- 如果视频存在，
lookupVideoMetadata 会返回视频的元数据。
- 如果视频不存在，API 会返回 404 错误代码。
示例请求
以下代码示例请求获取位于加利福尼亚州旧金山蒙哥马利街 600 号的泛美金字塔的鸟瞰视频。
curl -X GET "https://aerialview.googleapis.com/v1/videos:lookupVideoMetadata?key=YOUR_API_KEY&address=600%20Montgomery%20St%2C%20San%20Francisco%2C%20CA%2094111"
示例响应
以下 JSON 示例展示了对 lookupVideoMetadata 请求的所有可能响应。
找到视频
视频已渲染完毕。
{
"videoId": "Ul1naoFmqo69U1zUVrQRkc",
"captureDate": {
"year": 2022,
"month": 4,
"day": 1
},
"duration": "40s",
"state": "ACTIVE"
}
视频正在渲染
视频正在呈现。
{
"videoId": "Ul1naoFmqo69U1zUVrQRkc",
"state": "PROCESSING"
}
找不到视频
视频不在 Google 的数据库中。这可能是因为该位置信息尚未呈现，也可能是因为该位置信息位于不受支持的区域。
如果位置信息位于支持的区域，您可以使用 renderVideo 发起渲染请求。
{
"error": {
"code": 404,
"message": "Video not found.",
"status": "NOT_FOUND"
}
}
