OpenAI API 怎么走代理：环境变量、Python、Node 和 curl

# 1) Which IP and country does the world see through the proxy?
curl -x "http://USERNAME:PASSWORD@HOST:PORT" https://ipinfo.io/json

# 2) Does OpenAI accept this exit? Without a key: 403 = unsupported country; 401 = not a country problem
curl -s -o /dev/null -w "%{http_code}\n" -x "http://USERNAME:PASSWORD@HOST:PORT" \
  https://api.openai.com/v1/models

# 3) With your key: 200 and the list of models
curl -x "http://USERNAME:PASSWORD@HOST:PORT" https://api.openai.com/v1/models \
  -H "Authorization: Bearer $OPENAI_API_KEY"

# macOS / Linux (bash, zsh). Put the details in a variable once.
export PROXY_URL="http://USERNAME:PASSWORD@HOST:PORT"
export HTTP_PROXY="$PROXY_URL"
export HTTPS_PROXY="$PROXY_URL"
export http_proxy="$PROXY_URL"
export https_proxy="$PROXY_URL"
export NO_PROXY="localhost,127.0.0.1"

# Windows PowerShell
# $env:HTTPS_PROXY = "http://USERNAME:PASSWORD@HOST:PORT"
# $env:HTTP_PROXY  = $env:HTTPS_PROXY

# pip install -U "openai[httpx2]"   (needs Python 3.10 or later; reads OPENAI_API_KEY from the environment)
from openai import OpenAI, DefaultHttpx2Client

PROXY = "http://USERNAME:PASSWORD@HOST:PORT"   # HTTP line; for SOCKS5 see below
http = DefaultHttpx2Client(proxy=PROXY)

# 1) Which IP does the proxy show?
print(http.get("https://ipinfo.io/json").text)

# 2) Use the same client for the API
client = OpenAI(http_client=http)
for model in client.models.list():
    print(model.id)

# SOCKS5: pip install "httpx2[socks]", then use this line instead
# PROXY = "socks5://USERNAME:PASSWORD@HOST:PORT"

// npm install openai undici   (reads OPENAI_API_KEY from the environment)
// Save as check.mjs and run: node check.mjs
import OpenAI from 'openai';
import { fetch, ProxyAgent } from 'undici';

// If the password has special characters, wrap it: encodeURIComponent(password)
const dispatcher = new ProxyAgent('http://USERNAME:PASSWORD@HOST:PORT');

// 1) Which IP does the proxy show?
const ip = await fetch('https://ipinfo.io/json', { dispatcher });
console.log(await ip.text());

// 2) The same dispatcher for the API
const client = new OpenAI({ fetch, fetchOptions: { dispatcher } });
for await (const model of client.models.list()) {
  console.log(model.id);
}

// SOCKS5: use this line instead
// const dispatcher = new ProxyAgent('socks5://USERNAME:PASSWORD@HOST:PORT');

// Built-in route for HTTP proxies, Node 22.21+ / 24.5+, no SDK code:
// NODE_USE_ENV_PROXY=1 HTTPS_PROXY="http://USERNAME:PASSWORD@HOST:PORT" node check.mjs

# SOCKS5 line of the same IP (use the SOCKS5 port from My assets)
curl -x "socks5h://USERNAME:PASSWORD@HOST:PORT" https://ipinfo.io/json
