filter - Twitter 流按位置过滤

Question

Twitter Stream API 是否可以通过位置字段过滤推文？正如您在下面的示例 JSON 条目中看到的，有“location”:“philippines”字段 - 值。现在，我想要的只是通过位置字段过滤来自该位置的推文。但请不要误会我的意思。我不是在谈论 GEO 标签过滤器。

这可能吗？

检查 Twitter 流 API https://dev.twitter.com/docs/streaming-api/methods#locations

locations

Specifies a set of bounding boxes to track. Only tweets that are both created using the Geotagging API and are placed from within a tracked bounding box will be included in the stream – the user’s location field is not used to filter tweets (e.g. if a user has their location set to “San Francisco”, but the tweet was not created using the Geotagging API and has no geo element, it will not be included in the stream). Bounding boxes are specified as a comma separate list of longitude/latitude pairs, with the first pair denoting the southwest corner of the box. For example locations=-122.75,36.8,-121.75,37.8 would track tweets from the San Francisco area. Multiple bounding boxes may be specified by concatenating latitude/longitude pairs, for example: locations=-122.75,36.8,-121.75,37.8,-74,40,-73,41 would track tweets from San Francisco and New York City.

Just as with the track parameter, queries are subject to Track Limitations, described in Track Limiting and subject to access roles, described in the statuses/filter method. Both the number and size of bounding boxes is limited. Bounding boxes can be up to 360 degrees longitude by 180 degrees latitude, and you may specify up to 25 bounding boxes. A box of 360-degrees by 180-degrees will cover the whole earth. Higher access levels provide additional bounding boxes.

Bounding boxes are logical ORs. A locations parameter may be combined with track parameters, but note that all terms are logically ORd, so the query string track=twitter&locations=-122.75,36.8,-121.75,37.8 would match any tweets containing the term Twitter (even non-geo tweets) OR coming from the San Francisco area.

Values: longitude/latitude pairs, separated by commas. The first pair specifies the southwest corner of the box. Methods: statuses/filter

Example: Create a file called ‘locations’ that contains, excluding the quotation marks, the phrase: “locations=-122.75,36.8,-121.75,37.8,-74,40,-73,41” then execute:

curl -d @locations https://stream.twitter.com/1/statuses/filter.json
-uAnyTwitterUser:Password. 

You will receive all geo tagged tweets from the San Francisco and New York City area.
