Python:如何发送多个HTTP请求并接收响应? [英] Python: How can i send multiple HTTP requests and receive the response?

问题描述

如何以最快的方式发送1000个请求? 我知道您可以使用grequests发送多个请求:

How can I send like 1000 requests the fastest way? I know that you can send multiple request with grequests:

urls = [
    'sample.url/1',
    'sample.url/2',
    ...
]
request = (grequests.get(u) for u in urls)
print grequests.map(request)

但是返回的不是内容. 我需要获取json数据，例如这样的东西:

But the return is not the content. What I need is to get the json data, so for example something like this:

request = (grequests.get(u) for u in urls)
content = grequests.json(request)

推荐答案

返回的项目不是内容，但确实包含内容.您可以像这样获取所有内容:

The items returned are not the content, but they do include the content. You can fetch all of the content like so:

result = grequests.map(request)
content = '\n'.join(r.content for r in result) # raw content
text = '\n'.join(r.text for r in result)       # decoded content

您可以像这样解析json:

You can parse the json like this:

result = grequests.map(request)
json = [r.json() for r in result]

示例程序:

import grequests
import pprint

urls = [
    'http://httpbin.org/user-agent',
    'http://httpbin.org/headers',
    'http://httpbin.org/ip',
]

requests = (grequests.get(u) for u in urls)
responses = grequests.map(requests)

json = [response.json() for response in responses]
pprint.pprint(json)

text = '\n'.join(response.text for response in responses)
print(text)
