fgrequests: Fastest Asynchronous Group Requests

Installation

Install using pip:

pip install fgrequests

Documentation

Pretty easy to use.

import fgrequests

urls = [
    'https://google.com',
    'https://facebook.com',
    'https://twitter.com',
    'https://linkedin.com',
    'https://fakedomain.com'
]

Now lets make requests at the same time to the list of URLs (urls)

>>> response = fgreuests.build(urls)
>>> print(response)
[<Response [200]>, <Response [200]>, <Response [200]>, <Response [200]>, None]

By default fgrequests.build() returns a list of responses. If there have any invalid URL, the response will be None.

Method

By default this build() using GET method. There is a parameter which accepts methods named method. You can change this according to your need. method will accept these: GET, POST, PUT, DELETE, PATCH.

Lets send POST request in all of the urls

>>> response = fgreuests.build(urls, method='POST')
>>> print(response)
[<Response [405]>, <Response [200]>, <Response [200]>, <Response [200]>, None]

Headers

If you want to pass any headers you can simply pass your headers object (which may contain the authentication information) if you do like this:

>>> headers = {
    'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.95 Safari/537.36',
    "Authorization": "Bearer XXXXXXXXXXXXXXXTOKEN"
}
>>> response = fgreuests.build(urls, headers=headers)

Params/Payload

If you want to pass additional information while making requests, just pass your params / payload by following way:

>>> data = {
    'username': 'farid'
    'password': 'password123'
}
>>> response = fgreuests.build(urls, data=data)

Proxies

If you need to use a proxy, you can configure individual requests with the proxies argument to any request method:

>>> proxies = {
    'http': 'http://10.10.1.10:3128',
    'https': 'http://10.10.1.10:1080',
}
>>> response = fgreuests.build(urls, proxies=proxies)

To use HTTP Basic Auth with your proxy, use the http://user:password@host/ syntax:

>>> proxies = {'http': 'http://user:[email protected]:3128/'}

To give a proxy for a specific scheme and host, use the scheme://hostname form for the key. This will match for any request to the given scheme and exact hostname.

>>> proxies = {'http://10.20.1.128': 'http://10.10.1.10:5323'}

SSL Cert Verification

Requests verifies SSL certificates for HTTPS requests, just like a web browser. By default, SSL verification is enabled, and Requests will throw a SSLError if it’s unable to verify the certificate. Requests can also ignore verifying the SSL certificate if you set verify to False:

>>> response = fgrequests.build(urls, verify=False)

Worker

It has another parameter worker. By default the value of worker is 40. If you increase this it will work more faster. But there is a problem if you increase this too much, this will make a lot of pressure in your CPU cores which may freeze your system. If you reduce the value of worker you this will take more time to return responses. You can change the value of worker like this:

>>> response = fgreuests.build(urls, worker=70)

POST a Multipart-Encoded File

You can simply to upload Multipart-encoded files by using files parameter:

>>> urls = ['https://httpbin.org/post']
>>> files = {'file': open('report.xls', 'rb')}

>>> response = fgrequests.build(urls, method='POST', files=files)
>>> response[0].text
{
  ...
  "files": {
    "file": "<censored...binary...data>"
  },
  ...
}

You can set the filename, content_type and headers explicitly:

>>> urls = ['https://httpbin.org/post']
>>> files = {'file': ('report.xls', open('report.xls', 'rb'), 'application/vnd.ms-excel', {'Expires': '0'})}

>>> response = fgrequests.build(urls, method='POST', files=files)
>>> response[0].text
{
  ...
  "files": {
    "file": "<censored...binary...data>"
  },
  ...
}

If you want, you can send strings to be received as files:

>>> urls = ['https://httpbin.org/post']
>>> files = {'file': ('report.csv', 'some,data,to,send\nanother,row,to,send\n')}

>>> response = fgrequests.build(urls, method='POST', files=files)
>>> response[0].text
{
  ...
  "files": {
    "file": "some,data,to,send\\nanother,row,to,send\\n"
  },
  ...
}

Timeout

You can set timeout for the group request by using another parameter timeout. By default the value of timeout is 3 which is in seconds. You can change the value of timeout like this:

>>> response = fgreuests.build(urls, timeout=5)

Max Retries

You can put the count of maximum retries (to handle worst scenario) by using max_retries parameter. By default the value of max_retries is 1. You can change the value of max_retries like this:

>>> response = fgreuests.build(urls, max_retries=3)

Allow Redirects

You can disable redirection handling with the allow_redirects parameter. It only accepts Boolean, either True or False. By default it is True. You can change this by following way:

>>> response = fgreuests.build(urls, allow_redirects=False)

Execution Time

There have another parameter named show_execution_time. It returns the execution time (in sec). It accepts Boolean, either True or False. By default it is False. If you change this to True then fgrequests.build() will return an object. Lets check the output by making show_execution_time to True:

>>> response = fgrequests.build(urls, show_execution_time=True)
>>> print(response)
{
    'response_list': [<Response [200]>, <Response [200]>, <Response [200]>, <Response [200]>, None],
    'execution_time': 1.677
}
