• 异步 API：async_get()、async_post() 等
• 可复用的 CronetClient / AsyncCronetClient 会话
• HTTP、HTTPS、SOCKS5 和 SOCKS5H 代理
• Cookie 自动保存、发送、查询和删除
• 重定向、超时、证书验证和流式响应
• 有序请求头
• 内置及自定义 TLS Profile
• Rust 原生扩展，使用 PyO3 abi3-py36

安装

发布到 PyPI 后：

python -m pip install chrome_client

升级：

python -m pip install --upgrade chrome_client

快速开始

单次同步请求

import chrome_client

response = chrome_client.get("https://example.com")
response.raise_for_status()

print(response.status_code)
print(response.headers)
print(response.text)

同步 Session

import chrome_client

with chrome_client.CronetClient(
    verify=True,
    timeout_ms=30000,
    chrometls="chrome_150",
) as client:
    response = client.get(
        "https://example.com/api",
        params={"page": 1},
        headers={"accept": "application/json"},
    )
    print(response.json())

POST JSON

import chrome_client

response = chrome_client.post(
    "https://example.com/api",
    json={"name": "chrome_client"},
    timeout=30,
)

print(response.status_code)
print(response.json())

异步请求

下面的写法兼容 Python 3.6：

import asyncio
import chrome_client


async def main():
    async with chrome_client.AsyncCronetClient() as client:
        responses = await asyncio.gather(
            client.get("https://example.com/1"),
            client.get("https://example.com/2"),
        )
        for response in responses:
            print(response.status_code)


loop = asyncio.get_event_loop()
loop.run_until_complete(main())

Python 3.7 及以上也可以使用 asyncio.run(main())。

常用配置

代理

代理可以使用字符串或字典：

import chrome_client

client = chrome_client.CronetClient(
    proxies="http://127.0.0.1:8080"
)

# 也可以使用：
# proxies={"https": "http://user:password@127.0.0.1:8080"}
# proxies="socks5://127.0.0.1:1080"
# proxies="socks5h://user:password@127.0.0.1:1080"

response = client.get("https://example.com")
client.close()

证书验证

证书验证默认启用：

client = chrome_client.CronetClient(verify=True)

仅在明确需要访问测试环境或自签名服务时关闭：

client = chrome_client.CronetClient(verify=False)

verify 在 Session 创建时确定；请求方法中的同名参数仅用于兼容常见 HTTP 客户端接口。

超时

Session 使用毫秒：

client = chrome_client.CronetClient(timeout_ms=15000)

模块级请求使用秒：

response = chrome_client.get("https://example.com", timeout=15)

有序请求头

需要严格控制顺序时使用元组列表：

headers = [
    ("user-agent", "Mozilla/5.0"),
    ("accept", "text/html,application/xhtml+xml"),
    ("accept-language", "zh-CN,zh;q=0.9"),
]

response = chrome_client.get(
    "https://example.com",
    headers=headers,
)

Cookie

import chrome_client

with chrome_client.CronetClient(default_domain="example.com") as client:
    client.cookies.set("session", "value", domain="example.com")

    response = client.get("https://example.com/account")

    print(client.cookies.get("session", domain="example.com"))
    print(client.cookies.get_dict(domain="example.com"))

    client.cookies.delete("session", domain="example.com")

响应中的 Set-Cookie 会自动更新当前 Session 的 CookieJar。

TLS Profile

默认 Profile 是 chrome_150。当前内置配置可通过代码查看：

import chrome_client

print(sorted(chrome_client.get_tls_profiles().keys()))

选择 Profile：

client = chrome_client.CronetClient(chrometls="chrome_150")

增加自定义 Profile：

import chrome_client

profile = chrome_client.get_tls_profiles()["chrome_150"].copy()
profile["tls_curves"] = ["X25519MLKEM768", "X25519", "P-256", "P-384"]

chrome_client.add_tls_profile("chrome_custom", profile)

with chrome_client.CronetClient(chrometls="chrome_custom") as client:
    response = client.get("https://example.com")
    print(response.status_code)

相关函数：

• get_tls_profiles()：获取当前配置
• add_tls_profile(name, profile)：新增或更新一个配置
• set_tls_profiles(profiles)：替换当前进程中的全部配置
• clear_tls_profiles_cache()：清除缓存并在下次使用时重新读取文件

add_tls_profile() 和 set_tls_profiles() 只修改当前 Python 进程中的配置。需要持久化时，请修改 python/chrome_client/tls_profiles.json 后重新构建 Wheel。

流式响应

同步

import chrome_client

response = chrome_client.get("https://example.com/file", stream=True)
try:
    with open("download.bin", "wb") as output:
        for chunk in response.iter_content(64 * 1024):
            output.write(chunk)
finally:
    response.close()

异步

import asyncio
import chrome_client


async def download():
    async with chrome_client.AsyncCronetClient() as client:
        response = await client.get("https://example.com/file", stream=True)
        try:
            with open("download.bin", "wb") as output:
                async for chunk in response.aiter_content(64 * 1024):
                    output.write(chunk)
        finally:
            response.close()


loop = asyncio.get_event_loop()
loop.run_until_complete(download())

Response

常用属性和方法：

response.status_code
response.headers
response.cookies
response.content
response.text
response.json()
response.ok
response.raise_for_status()

异常类型：

from chrome_client import HTTPStatusError, RequestError

Linux 动态库排查

官方 Wheel 会携带所需的 Cronet 运行库。如果源码安装后出现：

libcronet.144.0.7506.0.so: cannot open shared object file

可以临时将包目录加入动态库搜索路径：

export LD_LIBRARY_PATH="$(python -c 'import os, chrome_client; print(os.path.dirname(chrome_client.__file__))'):$LD_LIBRARY_PATH"

如果使用的是 Alpine Linux，请改用 glibc 系发行版；当前 Wheel 不是 musllinux Wheel。
