Google在Python中放置API

Question

我使用python中的googleplacesapi来查找城市/城镇/地方（给定为位置）中的任何内容（以查询形式给出）。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，我的代码将结果的数量限制为20个，并且googlemaps在同一个查询中返回了20多个结果。如何检索所有结果？在

编辑：我添加了最后3行代码，试图在下一页上获得结果，但是我被抛出了无效的请求错误。在

谢谢你读我的问题。在

Answer 1

我发现出了什么问题。系统抛出无效的\u请求，因为next_page_令牌无效（在发出下一个\u page_令牌到它将生效之间有一个小的延迟b/w）。我编译了代码的前半部分（不包括最后三行），然后编译了最后三行代码，它成功了！！所以据我所知，延误是造成错误的原因。在

所以现在我要做的就是在最后一个if条件之前设置1-2秒的计时器。在

Answer 2

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.

将PagerToken作为附加参数添加到HTTP请求url中，如下所示
