python - How to GET requests for venues in foursquare with pycurl?

Question

I want to use the foursquare Python api to get the details of the venue. On my browser, I would click on the following url:

https://api.foursquare.com/v2/venues/1738652/?oauth_token=FKJBZCPQNFMVBDNPBMYFVXPDTMV0RWWKJGNAORPCNFERGBIG&v=20131011

...and get the appropriate response.

I am using the pycurl library with this code:

c = pycurl.Curl()
c.setopt(c.URL, 'https://api.foursquare.com/v2/venues/1738652/')
c.setopt(c.POSTFIELDS, '?oauth_token=FKJBZCPQNFMVBDNPBMYFVXPDTMV0RWWKJGNAORPCNFERGBIG&v=20131011')
c.perform()

but am getting the following error:

{"meta":{"code":405,"errorType":"other","errorDetail":"This endpoint only supports GET."},"response":{}}

I then tried to request with a GET:

import pycurl
import cStringIO

buf = cStringIO.StringIO()

c = pycurl.Curl()
c.setopt(c.URL, 'https://api.foursquare.com/v2/venues/1738652/?oauth_token=FKJBZCPQNFMVBDNPBMYFVXPDTMV0RWWKJGNAORPCNFERGBIG&v=20131011')
c.setopt(c.WRITEFUNCTION, buf.write)
c.perform()

print buf.getvalue()
buf.close()

...but got the same error.

你可以试试这个。获取请求。启用 DebugFunction 以跟踪请求表单链接时发生的情况。

import pycurl

def body(buf):
    for item in buf.strip().split('\n'):
        if item.strip():
            print item

def test(debug_type, debug_msg):
    if len(debug_msg) < 300:
        print "debug(%d): %s" % (debug_type, debug_msg.strip())

conn = pycurl.Curl()  
#conn.setopt(pycurl.USERNAME, username)
#conn.setopt(pycurl.PASSWORD, password)
#conn.setopt(pycurl.SSL_VERIFYPEER, False)
#conn.setopt(pycurl.CUSTOMREQUEST, 'LIST *.mp3')
conn.setopt(pycurl.NOBODY, False)
conn.setopt(pycurl.HEADER, True)
conn.setopt(pycurl.VERBOSE, True)
conn.setopt(pycurl.URL, 'https://api.foursquare.com/v2/venues/1738652/?oauth_token=FKJBZCPQNFMVBDNPBMYFVXPDTMV0RWWKJGNAORPCNFERGBIG&v=20131011')  
conn.setopt(pycurl.DEBUGFUNCTION, test)
conn.setopt(pycurl.WRITEFUNCTION, body)
conn.perform()
conn.close()

输出
