AttributeError：“ cStringIO.StringO”对象没有属性“ getValue”

Question

我是python的新手（但不是php），并且做了一些测试来自己学习。

当我使用数组中的URL运行代码时，出现此错误：

print req[1].getValue()
AttributeError: 'cStringIO.StringO' object has no attribute 'getValue'

当我检查属性时，可以看到：

['__add__', '__class__', '__contains__', '__delattr__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getitem__', '__getnewargs__', '__getslice__', '__gt__', '__hash__', '__init__', '__iter__', '__le__', '__len__', '__lt__', '__mul__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__rmul__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', 'count', 'index']
['__add__', '__class__', '__contains__', '__delattr__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getitem__', '__getnewargs__', '__getslice__', '__gt__', '__hash__', '__init__', '__iter__', '__le__', '__len__', '__lt__', '__mul__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__rmul__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', 'count', 'index']

当我检查

  

req.getValue（）

我明白了：

print req.getValue()
AttributeError: 'tuple' object has no attribute 'getValue'

我做错了什么？ 在这里找到代码：https://fragmentsofcode.wordpress.com/2011/01/22/pycurl-curlmulti-example/

    #urls = [...]  # list of urls
    # reqs: List of individual requests.
    # Each list element will be a 3-tuple of url (string), response string buffer
    # (cStringIO.StringIO), and request handle (pycurl.Curl object).
    reqs = []

    # Build multi-request object.
    m = pycurl.CurlMulti()
    for url in urls:
        response = StringIO()
        handle = pycurl.Curl()
        handle.setopt(pycurl.URL, url)
        handle.setopt(pycurl.WRITEFUNCTION, response.write)
        req = (url, response, handle)
        # Note that the handle must be added to the multi object
        # by reference to the req tuple (threading?).
        m.add_handle(req[2])
        reqs.append(req)

    # Perform multi-request.
    # This code copied from pycurl docs, modified to explicitly
    # set num_handles before the outer while loop.
    SELECT_TIMEOUT = 1.0
    num_handles = len(reqs)
    while num_handles:
        ret = m.select(SELECT_TIMEOUT)
        if ret == -1:
            continue
        while 1:
            ret, num_handles = m.perform()
            if ret != pycurl.E_CALL_MULTI_PERFORM:
                break

    # print response.getValue()

    for req in reqs:
        # req[1].getvalue() contains response content
        # print dir(req)
        print req[1].getValue()
