Question

我正在使用pycurl来访问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在所有其他选项都不存在时会出现。

Answer 1

手册显示使用情况为something like this：

>>> 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......

Answer 2

CURLOPT_RETURNTRANSFER不是libcurl选项，它是在PHP / CURL绑定中提供的

Answer 3

您是否尝试过执行print dir(pycurl)并查看属性列表中是否存在该选项？

pycurl：RETURNTRANSFER选项不存在
