Question

我正在尝试使用

从伦敦地区下载推文

curl --user xx:xx -X POST -d 'locations=-0.651,51.208,0.425,51.781' https://stream.twitter.com/1.1/statuses/filter.json > twitter.london.json

我收到的推文已经过时了。例如在（-6.71658144,50.48812681）中。那是为什么？

推文：

根据Twitter文档，location参数接受逗号分隔的经度，纬度对列表，指定一组边界框。

如果您只传入一个纬度和经度，那么它会将最近的推文返回到该位置。您是否还指定了过滤查询，如果是这样，这将大大减少返回的推文数量，这意味着最接近伦敦的推文实际上距离数英里。我有类似的问题。

话虽如此，我只是尝试了这个，如果你使用下面的lat和lon，没有其他过滤查询它运作良好。

{locations: [51.50,0.12,51.75,1.25]}

另一点值得注意的是，很多推文实际上并没有附加位置，而且通常情况下这些推文非常不准确，因为它们实际上可能来自其个人资料中指定的作者家庭位置。
