Python,Google Places API

问题描述 投票:1回答:1

我试图使用对Google Places API的python请求,在给定半径内的某个位置获取所有类型的餐厅。这是我的简单代码:

import requests
import json

APIKEY = "AIzaSyBFx8hqftDOlrSWRTiOSowjwfeS1OQtBpw"

def findPlaces(loc=("51.1079","17.0385"),radius=3000, pagetoken = None):
   lat, lng = loc
   type = "restaurant"
   url = "https://maps.googleapis.com/maps/api/place/nearbysearch/json?location={lat},{lng}&radius={radius}&type={type}&key={APIKEY}{pagetoken}".format(lat = lat, lng = lng, radius = radius, type = type,APIKEY = APIKEY, pagetoken = "&pagetoken="+pagetoken if pagetoken else "")
   print(url)
   response = requests.get(url)
   res = json.loads(response.text)
   print(res)
   for result in res["results"]:
      info = ";".join(map(str,[result["name"],result["geometry"]["location"]["lat"],result["geometry"]["location"]["lng"],result.get("rating",0),result["place_id"]]))
      print(info)
   pagetoken = res.get("next_page_token",None)
   return pagetoken


pagetoken = None
while True:
     pagetoken = findPlaces(pagetoken=pagetoken)
     if not pagetoken:
         break

然而,即使认为它对结果的第一页起作用也很好,但是没有明显的原因它没有进入第二页(它只是从API返回INVALID REQUEST)。此外,有趣的是,因为我将我的网址打印到控制台,我可以通过点击它来关注这个非常具体的网址,当我这样做时,它完美地工作,API返回所需的餐馆列表。

我认为这是一个编码urls的字符串的问题,我用python的urlencode替换了格式,但结果保持不变。由于我没有想法,我问:有没有人有这样的问题?

在此先感谢您的帮助。

我用新的纬度和经度对它进行了测试,得到了3个页面,每个20页,总结达到60个谷歌文档说。

https://developers.google.com/places/web-service/search

next_page_token包含一个令牌,可用于返回最多20个其他结果。如果没有要显示的其他结果,则不会返回next_page_token。可返回的最大结果数为60.发出next_page_token和有效时间之间会有短暂的延迟。

import requests
import json

APIKEY = "AIzaSyBFx8hqftDOlrSWRTiOSowjwfeS1OQtBpw"

def findPlaces(loc=("35.701474","51.405288"),radius=4000, pagetoken = None):
   lat, lng = loc
   type = "restaurant"
   url = "https://maps.googleapis.com/maps/api/place/nearbysearch/json?location={lat},{lng}&radius={radius}&type={type}&key={APIKEY}{pagetoken}".format(lat = lat, lng = lng, radius = radius, type = type,APIKEY = APIKEY, pagetoken = "&pagetoken="+pagetoken if pagetoken else "")
   print(url)
   response = requests.get(url)
   res = json.loads(response.text)
   # print(res)
   print("here results ---->>> ", len(res["results"]))

   for result in res["results"]:
      info = ";".join(map(str,[result["name"],result["geometry"]["location"]["lat"],result["geometry"]["location"]["lng"],result.get("rating",0),result["place_id"]]))
      print(info)
   pagetoken = res.get("next_page_token",None)

   print("here -->> ", pagetoken)

   return pagetoken
