Question

我正在尝试建立一个Twitter情绪分析工具，并希望添加一个地理位置 - 在纽约市10英里范围内寻找推文。我该怎么做呢？我试图将位置添加到网址的末尾，但它不起作用。

这是我到目前为止的代码：

import oauth2 as oauth
import urllib2 as urllib

# See assignment1.html instructions or README for how to get these credentials

api_key = ''
api_secret = ''
access_token_key = '
access_token_secret = ''

_debug = 0

oauth_token    = oauth.Token(key=access_token_key, secret=access_token_secret)
oauth_consumer = oauth.Consumer(key=api_key, secret=api_secret)

signature_method_hmac_sha1 = oauth.SignatureMethod_HMAC_SHA1()

http_method = "GET"


http_handler  = urllib.HTTPHandler(debuglevel=_debug)
https_handler = urllib.HTTPSHandler(debuglevel=_debug)

'''
Construct, sign, and open a twitter request
using the hard-coded credentials above.
'''
def twitterreq(url, method, parameters):
  req = oauth.Request.from_consumer_and_token(oauth_consumer,
                                             token=oauth_token,
                                             http_method=http_method,
                                             http_url=url, 
                                             parameters=parameters)

  req.sign_request(signature_method_hmac_sha1, oauth_consumer, oauth_token)

  headers = req.to_header()

  if http_method == "POST":
    encoded_post_data = req.to_postdata()
  else:
    encoded_post_data = None
    url = req.to_url()

  opener = urllib.OpenerDirector()
  opener.add_handler(http_handler)
  opener.add_handler(https_handler)

  response = opener.open(url, encoded_post_data)

  return response

def fetchsamples():

  url = "https://stream.twitter.com/1.1/statuses/filter.json?
  track=money&locations"
  parameters = []
  response = twitterreq(url, "GET", parameters)
  for line in response:
    print(line.strip())

if __name__ == '__main__':
  fetchsamples()

以下是API文档：https://developer.twitter.com/en/docs/tweets/filter-realtime/api-reference/post-statuses-filter.html

statuses/filter使用POST，而不是GET。

对于纽约市周边的推文使用＆＃34; locations = -74,40，-73,41＆＃34;。（您需要展开此边界框以使其在纽约市周围10英里。）但是，当与track一起使用时，两个过滤器都是“或”。换句话说，您会收到与您的locations过滤器或track过滤器匹配的推文。你不会只得到匹配两个过滤器的推文。

修改

url = "https://stream.twitter.com/1.1/statuses/filter.json?track=money&locations=-74,40,-73,41"
parameters = []
response = twitterreq(url, "POST", parameters)
