使用raw.gitmirror.com替换raw.githubusercontent.com以解决brew upgrade python@3.12慢的问题

MacOS系统上，升级python3.12时，超级慢，而且最后还失败了。看了日志，发现是用curl从raw.githubusercontent.com上下载Python安装包超时了。

解决方案一：开启翻墙工具，穿越围墙

解决方案二：使用raw.gitmirror.com替换raw.githubusercontent.com

翻墙有风险，操作需谨慎，这里我采用的是方案二。

1. 查看curl路径

which curl
# /usr/bin/curl

2. 编写自定义脚本，并赋予执行权限

ln -s `which curl` /usr/local/bin/curl
[ -d ~/.local/bin ] || mkdir -p ~/.local/bin/
cd ~/.local/bin
touch curl
chmod +x curl
# 注：PATH要配置到.bashrc或.zshrc里，别的窗口才能起作用
export PATH=$HOME/.local/bin:$PATH
vi curl
which curl
# ~/.local/bin/curl

3. 脚本内容

#!/usr/bin/env python
import os,sys
origin,target="raw.githubusercontent.com","raw.gitmirror.com"
args=" ".join(repr(i) if " " in i else i for i in sys.argv[1:])
cmd="/usr/bin/{} ".format(sys.argv[0].split('/')[-1])+args.replace(origin,target)
sys.exit(os.system(cmd))

4. 测试效果

curl https://raw.githubusercontent.com/Homebrew/homebrew-core/a775cbd0967da13128293d71fb26431fdedee6fb/Formula/m/mpdecimal.rb

5. 重新执行升级命令（这时候就很快了，不到一分钟就下载完毕，十分钟内就完成升级）

brew upgrade python@3.12

注: wget也可以用类似的方法加速

################# 2024.02.08 补充：

如果有外网服务器，还可以配个中转请求：

本地curl文件内容如下（需export JUMPER_IP='<服务器IP地址>'）

#!/usr/bin/env python
import os
import sys

try:
    from typing import List  # NOQA:F401
except ImportError:
    pass


def gen_cmd(sys_argv):
    # type: (List[str]) -> str
    args = []
    scheme = "https://"
    origin, target = "raw.githubusercontent.com", "raw.gitmirror.com"
    domains = ("objects.githubusercontent.com", "github.com")
    redirect = os.getenv("JUMPER_IP")
    host = "http://{}:9337/".format(redirect)
    for i in sys_argv[1:]:
        if i.startswith(scheme):
            j = i[len(scheme) :]
            if j.startswith(origin):
                i = i.replace(origin, target)
            elif redirect:
                for domain in domains:
                    if j.startswith(domain):
                        i = host + j
                        break
        elif " " in i:
            i = repr(i)
        args.append(i)
    tool = "/usr/local/bin/" + sys_argv[0].split("/")[-1]
    cmd = tool + " " + " ".join(args)
    return cmd


def main():
    # type: () -> int
    sys_argv = sys.argv
    if "--dry" in sys_argv:
        sys_argv = [i for i in sys_argv if i != "--dry"]
        print("--> " + gen_cmd(sys_argv))
        return 0
    return os.system(gen_cmd(sys_argv))


if __name__ == "__main__":
    sys.exit(main())

服务器上的app.py文件如下：

# pip install httpx orjson sanic gunicorn 'uvicorn[standard]'
from httpx import AsyncClient
from orjson import dumps, loads
from sanic import Sanic, raw

app = Sanic("Jumper", dumps=dumps, loads=loads)


@app.route("/<full:path>")
async def handler(request, full: str):
    host, url = full.lstrip("/"), ""
    try:
        host, url = host.split("/", 1)
    except ValueError:
        pass
    if host.startswith("http"):
        scheme, domain = host.split(".", 1)
    else:
        scheme, domain = "https", host
    async with AsyncClient(base_url=scheme + "://" + domain) as client:
        r = await client.get(url + "?" + request.query_string)
    return raw(r.content)


if __name__ == "__main__":
    app.run()

后台启动服务：

gunicorn app:app --bind 0.0.0.0:9337 --worker-class uvicorn.workers.UvicornWorker --daemon
