我正在尝试在 yelp 上收集餐厅信息。我有餐厅名称，并且正在使用 yelpapi。
我输入了以下内容：
from yelpapi import YelpAPI
yelp_api = YelpAPI(<key>, <secret>, <token>, <token secret>)
search_results = yelp_api.search_query(name = 'Neptune Oyster', location='Boston, MA'),
但最终列出了 20 家企业，但没有一家是正确的。我应该如何在我的 API 查询中指定餐厅名称？
另外，我将如何提取给定餐厅的所有评论？
谢谢！

较新的 Yelp Fusion API (v3) 对 API 的使用方式和返回信息进行了一些更改。简而言之，v2 可以通过一个电话获得评论。 v3 需要两次调用。下面是我如何让它工作。您的里程可能会有所不同。
#Finding reviews for a particular restaurant
import http.client
import json
import urllib
headers = {
'authorization': "Bearer <access_token>",
'cache-control': "no-cache",
'postman-token': "<token>"
}
#need the following parameters (type dict) to perform business search.
params = {'name':'Neptune oyster', 'address1':'63 Salem St.', 'city':'Boston', 'state':'MA', 'country':'US'}
param_string = urllib.parse.urlencode(params)
conn = http.client.HTTPSConnection("api.yelp.com")
conn.request("GET", "/v3/businesses/matches/best?"+param_string, headers=headers)
res = conn.getresponse()
data = res.read()
data = json.loads(data.decode("utf-8"))
b_id = data['businesses'][0]['id']
r_url = "/v3/businesses/" + b_id + "/reviews" #review request URL creation based on business ID
conn.request("GET",r_url,headers=headers)
rev_res = conn.getresponse() #response and read functions needed else error(?)
rev_data = rev_res.read()
yelp_reviews = json.loads(rev_data.decode("utf-8"))
print(json.dumps(yelp_reviews, indent=3, separators=(',', ': ')))

这是您要找的餐厅吗：
http://www.yelp.com/biz/neptune-oyster-boston?
最后一个“/”之后的所有内容都是餐厅的 yelp-id。
获得 yelp-id 后，您需要使用业务 api 来获取评论
这是业务 api 的文档
http://www.yelp.com/developers/documentation/v2/business
您获取评论的请求是这样的：
http://api.yelp.com/v2/business/neptune-oyster-boston
并且，特别是对于python yelpapi，请求可以构造为
yelp_api.business_api('neptune-oyster-boston')
它只给了我一个评论的sn-p，对于完整的评论，我想你可能不得不抓取网站。看看 BeautifulSoup 和 Scrapy。
最后，要回答您的第一个问题，请尝试在您的搜索参数中将 name 替换为 term。您可以在此页面上找到其他有效搜索参数的列表：
http://www.yelp.com/developers/documentation/v2/search_api
通过以下查询，api 给了我正确的业务。
yelp_api.search_query(term='neptune oysters', location='boston', limit=1)
祝你好运，刮刮乐！

使用term 而不是name 指定餐厅名称似乎可行。
from yelpapi import YelpAPI
yelp_api = YelpAPI(key, secret, token, token_secret)
search_results = yelp_api.search_query(term='Neptune Oyster', location='Boston, MA')
>>> for business in search_results['businesses']:
... print business['name']
...
Neptune Oyster
Island Creek Oyster Bar
B & G Oysters
Rabia's
Union Oyster House
Pauli's
James Hook & Co
Row 34
Atlantic Fish Company
Mare
The Oceanaire Seafood Room
Alive & Kicking Lobsters
The Daily Catch
Yankee Lobster Fish Market
The Barking Crab
Boston Chowda Co.
Legal Sea Foods
Salty Dog Seafood Grille & Bar
Legal Sea Foods
Legal Sea Foods
根据文档，您只能获得 1 篇评论摘录。您可以使用带有从搜索查询中获得的企业 ID 的企业查询来获取该信息：
>>> search_results = yelp_api.search_query(limit=1, term='Neptune Oyster', location='Boston, MA')
>>> if search_results['businesses'][0]['name'] == 'Neptune Oyster':
... business_id = search_results['businesses'][0]['id']
... business_results = yelp_api.business_query(id=business_id)
... for review in business_results['reviews']:
... print review['excerpt']
...
Price/Food
- Waited almost two hours for this place! I talked to some people that were waiting in line and they were all raving that Neptune is the BEST...
