feat: add configurable GitHub proxy settings (#401)

* docs: add GitHub proxy config design spec

* docs: add GitHub proxy config implementation plan

* feat(backend): use configurable github proxy for node upgrades

* feat(backend): use configurable github proxy for node install command

* feat(frontend): add github proxy config settings

* feat(script): support configurable github proxy in installer flows

Honor custom GitHub mirror settings across interactive and env-driven installer/update paths so script downloads match the panel configuration. Add shell regressions to lock down proxy prompting, URL recomputation, and non-interactive fallback behavior.

# GitHub 加速地址自定义配置实现计划
> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
**Goal:** 允许用户在面板设置中自定义 GitHub 加速地址,支持开启/关闭加速,配置影响全部下载场景。
**Architecture:** 使用现有 `vite_config` 表存储配置,后端 Handler 读取配置替换硬编码,前端复用现有配置项渲染逻辑,安装脚本支持环境变量和交互式询问。
**Tech Stack:** Go 1.24, React/TypeScript, Shell/Bash

## Task 1: 后端 - upgrade.go 修改
**Files:**
- Modify: `go-backend/internal/http/handler/upgrade.go`
- [x] **Step 1: 移除硬编码常量,添加配置读取函数**
在 `upgrade.go` 中,移除 `githubProxy` 常量,添加 `getGithubProxyConfig` 函数:
找到第 16-26 行:
```go
const (
githubRepo = "Sagit-chu/flvx"
githubProxy = "https://gcode.hostcentral.cc"
githubAPIBase = "https://api.github.com"
githubHTMLBase = "https://github.com"
upgradeTimeout = 5 * time.Minute
batchWorkers = 5
releaseChannelStable = "stable"
releaseChannelDev = "dev"
)
```
替换为:
```go
const (
githubRepo = "Sagit-chu/flvx"
githubAPIBase = "https://api.github.com"
githubHTMLBase = "https://github.com"
upgradeTimeout = 5 * time.Minute
batchWorkers = 5
releaseChannelStable = "stable"
releaseChannelDev = "dev"
defaultGithubProxyEnabled = true
defaultGithubProxyURL = "https://gcode.hostcentral.cc"
)
```
然后在 `releaseChannelLabel` 函数后(约第 71 行之后)添加新函数:
```go
// getGithubProxyConfig 获取 GitHub 加速配置
// 返回: (是否开启加速, 加速地址)
func (h *Handler) getGithubProxyConfig() (enabled bool, proxyURL string) {
enabled = defaultGithubProxyEnabled
proxyURL = defaultGithubProxyURL
if h == nil || h.repo == nil {
return
}
// 读取开启状态
if enabledCfg, err := h.repo.GetConfigByName("github_proxy_enabled"); err == nil && enabledCfg != nil {
enabled = enabledCfg.Value != "false"
}
// 读取加速地址
if urlCfg, err := h.repo.GetConfigByName("github_proxy_url"); err == nil && urlCfg != nil && urlCfg.Value != "" {
proxyURL = strings.TrimSpace(urlCfg.Value)
// 确保 URL 格式正确
if !strings.HasPrefix(proxyURL, "http://") && !strings.HasPrefix(proxyURL, "https://") {
proxyURL = "https://" + proxyURL
}
proxyURL = strings.TrimSuffix(proxyURL, "/")
}
return
}
// buildGithubDownloadURL 构建 GitHub 下载地址
func (h *Handler) buildGithubDownloadURL(version, filename string) string {
enabled, proxyURL := h.getGithubProxyConfig()
base := fmt.Sprintf("%s/%s/releases/download/%s/%s", githubHTMLBase, githubRepo, version, filename)
if enabled {
return fmt.Sprintf("%s/%s", proxyURL, base)
}
return base
}
```

githubProxy+"/%s/%s/releases/download/%s/gost-{ARCH}.sha256",
githubHTMLBase, githubRepo, version,
)
```
替换为:
```go
downloadURL := h.buildGithubDownloadURL(version, "gost-{ARCH}")
checksumURL := h.buildGithubDownloadURL(version, "gost-{ARCH}.sha256")
```
- [x] **Step 3: 修改 nodeBatchUpgrade 函数使用动态配置**
找到第 216-223 行:
```go

)
checksumURL := fmt.Sprintf(
githubProxy+"/%s/%s/releases/download/%s/gost-{ARCH}.sha256",
githubHTMLBase, githubRepo, version,
)
```
替换为:
```go
downloadURL := h.buildGithubDownloadURL(version, "gost-{ARCH}")
checksumURL := h.buildGithubDownloadURL(version, "gost-{ARCH}.sha256")
```

# GitHub 加速地址自定义配置设计
**日期**: 2026-04-01
**状态**: 待审核
**作者**: AI Assistant
## 概述
允许用户在面板设置中自定义 GitHub 加速地址,支持开启/关闭加速功能。配置后,面板更新节点、生成安装命令以及安装脚本都使用配置的加速地址。
## 背景
当前 `gcode.hostcentral.cc` 硬编码在多个位置:
- `go-backend/internal/http/handler/upgrade.go` - 节点升级下载 URL
- `go-backend/internal/http/handler/mutations.go` - 节点安装命令生成
- `install.sh` - 节点安装脚本
- `panel_install.sh` - 面板安装脚本
用户无法自定义加速地址或关闭加速功能。
## 目标
1. 面板设置中支持配置加速开关和加速地址
2. 配置影响全部下载场景(面板端 + 安装脚本)
3. 安装脚本支持交互式询问加速配置
4. 面板生成的安装命令自动嵌入加速配置
## 影响范围
### 后端
- `go-backend/internal/http/handler/upgrade.go`
- `go-backend/internal/http/handler/mutations.go`
### 前端
- `vite-frontend/src/pages/config.tsx`
- `vite-frontend/src/config/site.ts`(缓存配置键)
### 安装脚本
- `install.sh`
- `panel_install.sh`
## 详细设计
### 1. 数据存储
使用现有 `vite_config` 表存储两个配置项:
| name | value | 说明 |
|------|-------|------|
| `github_proxy_enabled` | `"true"` / `"false"` | 是否开启加速,默认 `"true"` |
| `github_proxy_url` | URL 字符串 | 加速地址,默认 `"https://gcode.hostcentral.cc"` |
### 2. 后端 Handler 修改
#### upgrade.go
移除硬编码常量,新增辅助函数:
```go
// getGithubProxyConfig 获取 GitHub 加速配置
// 返回: (是否开启, 加速地址)
func (h *Handler) getGithubProxyConfig() (enabled bool, proxyURL string) {
enabled = true // 默认开启
proxyURL = "https://gcode.hostcentral.cc" // 默认地址
if h == nil || h.repo == nil {
return
}
// 读取开启状态
if enabledCfg, err := h.repo.GetConfigByName("github_proxy_enabled"); err == nil && enabledCfg != nil {
enabled = enabledCfg.Value != "false"
}
// 读取加速地址
if urlCfg, err := h.repo.GetConfigByName("github_proxy_url"); err == nil && urlCfg != nil && urlCfg.Value != "" {
proxyURL = strings.TrimSpace(urlCfg.Value)
// 确保 URL 格式正确
if !strings.HasPrefix(proxyURL, "http://") && !strings.HasPrefix(proxyURL, "https://") {
proxyURL = "https://" + proxyURL
}
proxyURL = strings.TrimSuffix(proxyURL, "/")
}
return
}
// buildDownloadURL 构建下载地址
func (h *Handler) buildDownloadURL(version, arch string) string {
enabled, proxyURL := h.getGithubProxyConfig()
base := fmt.Sprintf("https://github.com/%s/releases/download/%s/gost-%s", githubRepo, version, arch)
if enabled {
return fmt.Sprintf("%s/%s", proxyURL, base)
}
return base
}
```
修改 `nodeUpgrade` 和 `nodeBatchUpgrade` 使用动态配置。
#### mutations.go
修改 `getNodeInstallCmd` 函数(约第 440-456 行):
```go
func (h *Handler) getNodeInstallCmd(w http.ResponseWriter, r *http.Request) {
// ... 现有逻辑 ...
enabled, proxyURL := h.getGithubProxyConfig()
var cmd string
if enabled {
cmd = fmt.Sprintf(
"curl -L %s/https://github.com/%s/releases/download/%s/install.sh -o ./install.sh && chmod +x ./install.sh && PROXY_ENABLED=true PROXY_URL=%s VERSION=%s ./install.sh -a %s -s %s",
proxyURL, githubRepo, version, proxyURL, version, processServerAddress(panelAddr), secret,
)
} else {
cmd = fmt.Sprintf(
"curl -L https://github.com/%s/releases/download/%s/install.sh -o ./install.sh && chmod +x ./install.sh && PROXY_ENABLED=false VERSION=%s ./install.sh -a %s -s %s",
githubRepo, version, version, processServerAddress(panelAddr), secret,
)
}
response.WriteJSON(w, response.OK(cmd))
}
```
### 3. 前端修改
#### config.tsx
在 `CONFIG_ITEMS` 数组中添加配置项(约第 87-158 行之后):
```typescript
{
key: "github_proxy_enabled",
label: "开启 GitHub 加速",
description: "用于节点更新和安装脚本下载,解决部分地区 GitHub 访问受限问题",
type: "switch",
},
{
key: "github_proxy_url",
label: "加速地址",
placeholder: "https://gcode.hostcentral.cc",
description: "GitHub 下载加速代理地址,开启加速后生效",
type: "input",
dependsOn: "github_proxy_enabled",
dependsValue: "true",
},
```
在 `getInitialConfigs` 函数的 `configKeys` 数组中添加缓存键:
```typescript
"github_proxy_enabled",
"github_proxy_url",
```
### 4. 安装脚本修改
#### install.sh
在脚本开头添加配置变量和环境变量读取:
```bash
# 镜像加速配置(可由面板传入)
PROXY_ENABLED="${PROXY_ENABLED:-}"
PROXY_URL="${PROXY_URL:-}"
```
修改 `maybe_proxy_url` 函数:
```bash
# 镜像加速
maybe_proxy_url() {
local url="$1"
# 如果明确关闭加速
if [[ "$PROXY_ENABLED" == "false" ]]; then
echo "$url"
return
fi
# 默认开启加速
local proxy="${PROXY_URL:-gcode.hostcentral.cc}"
# 处理 URL 格式
if [[ "$proxy" == https://* || "$proxy" == http://* ]]; then
proxy="${proxy%/}" # 移除末尾斜杠
else
proxy="https://${proxy}"
fi
echo "${proxy}/${url}"
}
```
在 `install_flux_agent` 函数开头添加交互式询问:
```bash
install_flux_agent() {
echo "🚀 开始安装 flux_agent..."
# 询问加速配置(如果未由面板传入)
if [[ -z "$PROXY_ENABLED" ]]; then
echo ""
read -p "是否开启 GitHub 加速? (Y/n): " proxy_choice
case "$proxy_choice" in
n|N) PROXY_ENABLED="false" ;;
*)
PROXY_ENABLED="true"
read -p "加速地址 (默认 gcode.hostcentral.cc): " input_url
PROXY_URL="${input_url:-gcode.hostcentral.cc}"
;;
esac
fi
# ... 现有安装逻辑 ...
}
```
#### panel_install.sh
类似修改,在 `install_panel` 函数开头添加询问逻辑。
### 5. 配置缓存
#### site.ts
在配置缓存键列表中添加新键(如果需要前端缓存加速配置)。
## 默认行为
- `github_proxy_enabled`: 默认 `"true"`(开启加速)
- `github_proxy_url`: 默认 `"https://gcode.hostcentral.cc"`
## 测试要点
1. **后端 API 测试**:
- 未配置时使用默认值
- 配置后正确读取并应用
- 关闭加速后直连 GitHub
2. **前端 UI 测试**:
- Switch 开关正确切换
- 关闭加速时隐藏地址输入框
- 保存配置后正确持久化
3. **安装脚本测试**:
- 交互式询问正常工作
- 环境变量传入时跳过询问
- 加速关闭时直连 GitHub
4. **集成测试**:
- 面板生成安装命令正确包含加速配置
- 节点升级下载使用配置的加速地址
## 风险与缓解
| 风险 | 缓解措施 |
|------|----------|
| 用户输入无效加速地址 | 后端验证 URL 格式,前端添加格式提示 |
| 旧版本安装脚本不兼容 | 保持 `maybe_proxy_url` 函数签名不变,仅修改内部逻辑 |
| 配置缺失时行为不一致 | 在 `getGithubProxyConfig` 中提供合理的默认值 |
