我正在使用 pycurl 访问 JSON Web API,但是当我尝试使用以下内容时:

ocurl.setopt(pycurl.URL, gaurl)       # host + endpoint
ocurl.setopt(pycurl.RETURNTRANSFER, 1)
ocurl.setopt(pycurl.HTTPHEADER, gaheader) # Send extra headers
ocurl.setopt(pycurl.CUSTOMREQUEST, "POST") # HTTP POST req
ocurl.setopt(pycurl.CONNECTTIMEOUT, 2)

并执行脚本,它失败了。

File "getdata.py", line 46, in apicall
ocurl.setopt(pycurl.RETURNTRANSFER, 1)
AttributeError: 'module' object has no attribute 'RETURNTRANSFER'

我不知道发生了什么,以及为什么 RETURNTRANSFER 似乎不存在,而所有其他选项都存在。

该手册显示用法如下

>>> import pycurl
>>> import StringIO
>>> b = StringIO.StringIO()
>>> conn = pycurl.Curl()
>>> conn.setopt(pycurl.URL, 'http://www.example.org')
>>> conn.setopt(pycurl.WRITEFUNCTION, b.write)
>>> conn.perform()
>>> print b.getvalue()

似乎有点迂回,但我不是 PycURL 的忠实粉丝......

CURLOPT_RETURNTRANSFER 不是 libcurl 选项,但它在 PHP/CURL 绑定中提供

您是否尝试过执行print dir(pycurl)并查看该选项是否存在于属性列表中?
