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，也不知道为什么 RETURNTRANSFER 似乎不存在，而所有其他选项都存在。
最佳答案
手册显示用法为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()

看起来有点迂回，但我不是 PycURL 的忠实粉丝......
关于python - pycurl: RETURNTRANSFER 选项不存在，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/872844/
