python - Python 中的 Google Places API

Question

我正在使用 python 中的 Google Places API 来查找城市/城镇/地点(作为位置给出)中的任何内容(作为查询给出)。以下是我的代码片段:

from googleplaces import GooglePlaces, types, lang


YOUR_API_KEY = 'xxxx'
google_places = GooglePlaces(YOUR_API_KEY)

query_result = google_places.text_search(
        query='Play Schools', location = 'Mumbai, India')
print(len(query_result.places))
for place in query_result.places:
    print (place.name)
    print (place.place_id)
    print('\n')

if (query_result.has_next_page_token):
query_result_next_page = google_places.text_search(
        pagetoken=query_result.next_page_token)

现在的问题是我的代码将结果数限制为 20，而 Google map 在同一个查询中返回的结果超过 20 个。我该如何检索所有结果？

编辑:我添加了最后 3 行代码以尝试在下一页上获取结果，但出现 INVALID_REQUEST 错误。

感谢阅读我的问题。

Answer 1

By default, each Nearby Search or Text Search returns up to 20 establishment results per query; however, each search can return as many as 60 results, split across three pages. If your search will return more than 20, then the search response will include an additional value — next_page_token. Pass the value of the next_page_token to the pagetoken parameter of a new search to see the next set of results. If the next_page_token is null, or is not returned, then there are no further results. There is a short delay between when a next_page_token is issued, and when it will become valid. Requesting the next page before it is available will return an INVALID_REQUEST response. Retrying the request with the same next_page_token will return the next page of results.

像这样添加 PagerToken 作为 HTTP 请求 url 的附加参数
