Python requestsでプロキシを使う方法

import requests

# The four values come with your order (dashboard or API)
proxy = "http://USERNAME:PASSWORD@HOST:PORT"

response = requests.get(
    "https://example.com/",
    proxies={"http": proxy, "https": proxy},
    timeout=30,
)
response.raise_for_status()
print(response.status_code)

import requests

proxy = "http://USERNAME:PASSWORD@HOST:PORT"

with requests.Session() as session:
    # HTTP_PROXY / HTTPS_PROXY in the environment would override
    # session.proxies; this makes the session use only its own setting.
    session.trust_env = False
    session.proxies.update({"http": proxy, "https": proxy})
    response = session.get("https://example.com/", timeout=30)
    response.raise_for_status()
    print(response.status_code)

# pip install "requests[socks]"
import requests

# Switch the proxy to SOCKS5 first; use the values the order then shows.
# socks5h: the proxy resolves the hostname, not your machine.
proxy = "socks5h://USERNAME:PASSWORD@HOST:PORT"

response = requests.get(
    "https://example.com/",
    proxies={"http": proxy, "https": proxy},
    timeout=30,
)
response.raise_for_status()
print(response.status_code)
