一个自动下载最新版本frp打包成deb的bash脚本

frp作者不仅不提供任何发行版的包，甚至把systemd文件给删了1，我每次安装都费劲拖目录写配置，今天花了点时间在gpt帮助下写了个bash脚本，自动从github release下载最新版本frp并打包成deb，这下舒服了。注意替换github api token。需要的依赖：curl,jq 好像没了

#!/bin/bash

# Personal access token
github_token="<GITHUB_API_TOKEN 换成你自己的>"

function get_latest_release() {
    # Send a GET request to the GitHub API
    curl -s -H "Accept: application/vnd.github.v3+json" -H "Authorization: Bearer $github_token" "$github_api_url" |
        jq -r .tag_name
}

function download_release() {
    local version=$1
    version="${version#v}"
    # GitHub release asset URL for the binary
    asset_url="https://mirror.ghproxy.com/github.com/$repo_owner/$repo_name/releases/download/v$version/${binary_name}_${version}_${os}_${arch}.tar.gz"

    # Check if the file already exists
    if [[ ! -e "${binary_name}_${version}_${os}_${arch}.tar.gz" ]]; then
        # Download the release binary
        wget "$asset_url"

        echo "Downloaded frp $version for ${os}_${arch}."
