Question

我正在使用grequests来对crunchbase API做几个请求。

不幸的是，他们没有提供基于公司更新时间查询数据的方法，所以为了获得最近资助的公司，我必须抓住他们所有的公司名称，然后对每家公司执行个别请求。 / p>

尝试多处理后，我找到了模块grequest。代码如下：

import grequests

def query():
    names = [list of company names] #around 200 per chunk
    base_url = 'http://api.crunchbase.com/v/1/company/%s.js?api_key=%s' % ('%s',API_KEY)
    rs = (grequests.get(u) for u in urls)
    chunk_responses = grequests.imap(rs, size = 5)

但是，我似乎得到以下错误：

Traceback (most recent call last):

我知道为什么会收到此错误？

Python - grequests socket.gaierror：[Errno -2]名称或服务未知）
