注意
下面的答案是不适用于请求v0.13.0 +。编写此问题后，异步功能已移至
grequests。但是，你可以将其替换
requests为
grequests下面的内容，它应该可以工作。
我已经留下了这个答案，以反映原始问题，即有关使用请求
<v0.13.0的问题。
要
async.map异步执行多个任务，你必须：
- 为每个对象定义一个函数（你的任务）
- 将该功能添加为请求中的事件挂钩
- 调用async.map所有请求/操作的列表
例：
from requests import async# If using requests > v0.13.0, use# from grequests import asyncurls = [ 'http://python-requests.org', 'http://httpbin.org', 'http://python-guide.org', 'http://kennethreitz.com']# A simple task to do to each response objectdef do_something(response): print response.url# A list to hold our things to do via asyncasync_list = []for u in urls: # The "hooks = {..." part is where you define what you want to do # # Note the lack of parentheses following do_something, this is # because the response will be used as the first argument automatically action_item = async.get(u, hooks = {'response' : do_something}) # Add the task to our list of things to do via async async_list.append(action_item)# Do our list of things to do via asyncasync.map(async_list)
