Request Curl

A user-friendly wrapper for pycurl that simplifies HTTP requests.

Installation

Use the package manager pip to install request_curl.

NOTE: You need Python and libcurl installed on your system to use or build pycurl. Some RPM distributions of curl/libcurl do not include everything necessary to build pycurl, in which case you need to install the developer specific RPM which is usually called curl-dev.

pip install request_curl

Quickstart

A request_curl session manages cookies, connection pooling, and configurations.

Basic Usage:

import request_curl
s = request_curl.Session()
s.get('https://httpbin.org/get') # returns <Response [200]>
s.request('GET', 'https://httpbin.org/get') # returns <Response [200]>

Using a Context Manager

import request_curl
with request_curl.Session() as session:
    session.get('https://httpbin.org/get') # returns <Response [200]>

Features

Response Object

The response object is similar to that of the requests library.

import request_curl
s = request_curl.Session()
r = s.get("https://httpbin.org/get")

print(r) # prints response object
print(r.status_code) # prints status code
print(r.content) # prints response content in bytes
print(r.text) # prints response content as text
print(r.json) # prints response content as JSON
print(r.url) # prints response URL
print(r.headers) # prints response headers

Proxy Support

Format the proxy as a string.

import request_curl
s = request_curl.Session()
# supports authentication: r = s.get("https://httpbin.org/get", proxies="ip:port:user:password")
r = s.get("https://httpbin.org/get", proxies="ip:port")

HTTP2

HTTP2 is disabled by default.

import request_curl
s = request_curl.Session(http2=True)
r = s.get("https://httpbin.org/get")

Cipher Suites

You can specify custom cipher suites as an array.

import request_curl

cipher_suite = [
    "AES128-SHA256",
    "AES256-SHA256",
    "AES128-GCM-SHA256",
    "AES256-GCM-SHA384"
]
s = request_curl.Session(cipher_suite=cipher_suite)
r = s.get("https://httpbin.org/get")

Debug Request

Set debug to True to print raw input and output headers.

import request_curl
s = request_curl.Session()
r = s.get("https://httpbin.org/get", debug=True)

Custom Headers

Specify custom headers as a dictionary.

import request_curl
s = request_curl.Session()
headers = {
    "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.163 Safari/537.36"
}
r = s.get("https://httpbin.org/get", headers=headers)

Data

import request_curl
s = request_curl.Session()

# sending form data
form_data = {"key": "value"}
response = s.post("https://httpbin.org/post", data=form_data)

# sending json data
json_data = {"key": "value"}
response = s.post("https://httpbin.org/post", json=json_data)

Usage with Curl-Impersonate

To use request_curl with curl-impersonate, opt for our custom Docker image by either pulling or building it. The image comes with request_curl and curl-impersonate pre-installed. Check below for a demonstration on impersonating firefox98 tls-fingerprint and request_curl with our custom Docker Image.

Note: This feature is still considered experimental. Only tested with firefox fingerprint

To pull the Docker image:

docker pull h3adex/request-curl-impersonate:latest
docker run --rm -it h3adex/request-curl-impersonate

Example Python code for a target website:

import request_curl
from request_curl import FIREFOX98_CIPHER_SUITE, FIREFOX98_HEADERS

# impersonates ff98
session = request_curl.Session(
    http2=True, 
    cipher_suite=FIREFOX98_CIPHER_SUITE, 
    headers=FIREFOX98_HEADERS
)
response = session.get("https://tls.browserleaks.com/json")
# <Response [200]>
# "ja3_hash":"25e9b0dd5b8e9330b206eae87e885e19"
# same result as: 
# docker run --rm lwthiker/curl-impersonate:0.5-ff curl_ff98 https://tls.browserleaks.com/json
