使用Python发送URL数据Curl / Json

Question

我正在尝试在带有url参数的python中使用curl，但是它返回“ None”，在php中具有相同参数的相同api正常工作。 这是我的python代码：

from StringIO import StringIO
import pycurl, json

apiurl = 'http://servername.com:7705'

data = json.dumps({"node": "test", "type": "get_by_field"})

c = pycurl.Curl()
c.setopt(pycurl.URL, apiurl)
c.setopt(pycurl.HTTPHEADER, ['Accept: application/json'])
c.setopt(pycurl.POST, 1)
c.setopt(pycurl.POSTFIELDS, data)
response = c.perform()
c.close()
print response

Answer 1

尝试这个

import StringIO
import pycurl, json

fout = StringIO.StringIO()

apiurl = 'http://servername.com:7705'

data = json.dumps({"node": "test", "type": "get_by_field"})

c = pycurl.Curl()
c.setopt(pycurl.WRITEFUNCTION, fout.write)

c.setopt(pycurl.URL, apiurl)
c.setopt(pycurl.HTTPHEADER, ['Accept: application/json'])
c.setopt(pycurl.POST, 1)
c.setopt(pycurl.POSTFIELDS, data)
c.perform()
c.getinfo(pycurl.RESPONSE_CODE)
fout.getvalue()
