推荐答案

Matt是正确的，您可以使用offset参数，但是他的链接文档和示例url有点差.

Matt is correct that you can use the offset parameter but his linked documentation and sample url was a little off.

您似乎正在使用场所/探索端点，可以在此处找到相关文档:

It looks like you're using the venues/explore endpoint, you can find documentation on this here: https://developer.foursquare.com/docs/venues/explore

要浏览结果，您可以设置以下内容:

To page through results you would set up something like this:

https://api.foursquare.com/v2/venues/explore?client_secret=****&client_id=****&v=20161101&limit=50&near=San Francisco, CA&section=food

在响应(json)中，您应该检查json['response']['totalResults']值以查看总共有多少结果.

In your response (json) you should inspect the json['response']['totalResults'] value to see how many results there are in total.

for (var i = 0; i < totalResults/50; i++) {
    url = 'https://api.foursquare.com/v2/venues/explore?client_secret=****&client_id=****&v=20161101&limit=50&near=San Francisco, CA&section=food&offset='(i + 1)*50';
}

看起来您正在使用的某些参数无效.

It also looks like some of the parameters that you're using are invalid.

1. near参数应为San Francisco, CA而不是San Francisco, San Francisco
2. 该API没有novelty参数，您是说要使用limit吗?

1. The near parameter should be San Francisco, CA not San Francisco, San Francisco
2. There is no novelty parameter with that API, do you mean to use limit?
