Client methods

The Client class provides a set of methods for making HTTP requests: get, head, options, delete, post, put, patch, each of which internally utilizes the request() method for execution. The parameters for these methods closely resemble those in httpx.

def get(
    url: str,
    params: dict[str, str] | None = None,
    headers: dict[str, str] | None = None,
    cookies: dict[str, str] | None = None,
    auth: tuple[str, str| None] | None = None,
    auth_bearer: str | None = None,
    timeout: float | None = 30,
):
    """Performs a GET request to the specified URL.

    Args:
        url (str): The URL to which the request will be made.
        params (dict[str, str] | None): A map of query parameters to append to the URL. Default is None.
        headers (dict[str, str] | None): A map of HTTP headers to send with the request. Default is None.
        cookies (dict[str, str] | None): - An optional map of cookies to send with requests as the `Cookie` header.
        auth (tuple[str, str| None] | None): A tuple containing the username and an optional password
            for basic authentication. Default is None.
        auth_bearer (str | None): A string representing the bearer token for bearer token authentication. Default is None.
        timeout (float | None): The timeout for the request in seconds. Default is 30.

Examples

import primp

# Impersonate
client = primp.Client(impersonate="chrome_131", impersonate_os="windows")

# Update headers
headers = {"Referer": "https://cnn.com/"}
client.headers_update(headers)

# GET request
resp = client.get("https://tls.peet.ws/api/all")

# GET request with passing params and setting timeout
params = {"param1": "value1", "param2": "value2"}
resp = client.post(url="https://httpbin.org/anything", params=params, timeout=10)

# Stream response
resp = client.get("https://nytimes")
for chunk in resp.stream():
    print(chunk)

# Cookies set
cookies = {"c1_n": "c1_value", "c2_n": "c2_value"}
client.set_cookies(url="https://nytimes.com", cookies) # set cookies for a specific domain
client.get("https://nytimes.com/", cookies=cookies)  # set cookies in request

# Cookies get
cookies = client.get_cookies(url="https://nytimes.com")  # get cookies for a specific domain
cookies = resp.cookies  # get cookies from response

# POST Binary Request Data
content = b"some_data"
resp = client.post(url="https://httpbin.org/anything", content=content)

# POST Form Encoded Data
data = {"key1": "value1", "key2": "value2"}
resp = client.post(url="https://httpbin.org/anything", data=data)

# POST JSON Encoded Data
json = {"key1": "value1", "key2": "value2"}
resp = client.post(url="https://httpbin.org/anything", json=json)

# POST Multipart-Encoded Files
files = {'file1': '/home/root/file1.txt', 'file2': 'home/root/file2.txt'}
resp = client.post("https://httpbin.org/post", files=files)

# Authentication using user/password
resp = client.post(url="https://httpbin.org/anything", auth=("user", "password"))

# Authentication using auth bearer
resp = client.post(url="https://httpbin.org/anything", auth_bearer="bearerXXXXXXXXXXXXXXXXXXXX")

# Using proxy or env var PRIMP_PROXY
resp = primp.Client(proxy="http://127.0.0.1:8080")  # set proxy in Client
export PRIMP_PROXY="socks5://127.0.0.1:1080"  # set proxy as environment variable

resp = primp.Client(ca_cert_file=certifi.where())
export PRIMP_CA_BUNDLE="/home/user/Downloads/cert.pem"  # set as environment variable

# You can also use convenience functions that use a default Client instance under the hood:
# primp.get() | primp.head() | primp.options() | primp.delete() | primp.post() | primp.patch() | primp.put()
# These functions can accept the `impersonate` parameter:
resp = primp.get("https://httpbin.org/anything", impersonate="chrome_131", impersonate_os="android")

II. AsyncClient

primp.AsyncClient() is an asynchronous wrapper around the primp.Client class, offering the same functions, behavior, and input arguments.

import asyncio
import logging

import primp

async def aget_text(url):
    async with primp.AsyncClient(impersonate="chrome_131") as client:
        resp = await client.get(url)
        return resp.text

async def main():
    urls = ["https://nytimes.com/", "https://cnn.com/", "https://abcnews.go.com/"]
    tasks = [aget_text(u) for u in urls]
    results = await asyncio.gather(*tasks)

if __name__ == "__main__":
    logging.basicConfig(level=logging.INFO)
    asyncio.run(main())
