频道是 Capgo 中应用更新管理的核心机制。在自托管模式下,您需要实现频道端点来处理设备分配、频道查询和频道管理操作。
了解频道
标题:了解频道频道允许您:
- 控制更新分发: 将不同应用版本分配给不同用户组
- AB 测试: 使用特定用户段测试新功能
- 分阶段发布: 逐步部署更新以降低风险
- 环境隔离: 分别隔离开发、测试和生产环境的更新
配置
配置在您的 capacitor.config.json:
{ "plugins": { "CapacitorUpdater": { "channelUrl": "https://myserver.com/api/channel_self" } }}频道操作
频道操作插件执行的频道操作将由您的端点处理:
1. 列出兼容频道(GET 请求)
1. 列出兼容频道(GET 请求)当插件调用时 listChannels()它会发送一个 GET 请求以获取与设备兼容的所有通道。这将返回与设备环境(dev/prod、emulator/real device)匹配的通道,并允许公共访问或自我分配。
请求格式
标题:请求格式// GET /api/channel_self// Headers:{ "Content-Type": "application/json"}
// Query parameters:interface ListChannelsRequest { app_id: string platform: "ios" | "android" | "electron" is_emulator: boolean is_prod: boolean key_id?: string}响应格式
标题:响应格式[ { "id": 1, "name": "production", "public": true, "allow_self_set": false }, { "id": 2, "name": "beta", "public": false, "allow_self_set": true }]了解通道类型
标题:了解通道类型响应中包含每个通道的两个重要标志:
-
public: true: 这是 默认频道. 设备无法自行将其分配为此频道setChannel(). 如果设备移除其频道分配(使用unsetChannel()),它将自动从公共频道接收更新,如果它匹配设备的条件 -
allow_self_set: true: 这是 自分配频道. 设备可以使用setChannel()explicitly 将自己分配到此频道。 这对于测试、A/B测试或允许用户选择特定更新跟踪非常有用
2. 获取频道 (PUT 请求)
标题为“2. 获取频道 (PUT 请求)”当插件调用 getChannel()时,它会发送一个 PUT 请求来检索设备的当前频道分配。
请求格式
标题为“请求格式”// PUT /api/channel_self// Headers:{ "Content-Type": "application/json"}
// Body:interface GetChannelRequest { device_id: string app_id: string platform: "ios" | "android" | "electron" plugin_version: string version_build: string version_code: string version_name: string is_emulator: boolean is_prod: boolean defaultChannel?: string channel?: string // For newer plugin versions, contains local channel override}响应格式
标题为“响应格式”{ "status": "ok", "channel": "production", "allowSet": true, "message": "", "error": ""}3. 设置频道 (POST 请求)
Section titled “3. 设定频道 (POST 请求)””当插件调用 setChannel()它会发送一个 POST 请求来将设备分配到特定的频道。
// POST /api/channel_selfinterface SetChannelRequest { device_id: string app_id: string channel: string platform: "ios" | "android" | "electron" plugin_version: string version_build: string version_code: string version_name: string is_emulator: boolean is_prod: boolean}{ "status": "ok", "message": "Device assigned to channel successfully", "error": ""}当设备尝试将自己分配到 公共频道 (一个有 public: true),您的端点应返回错误:
{ "status": "error", "error": "public_channel_self_set_not_allowed", "message": "This channel is public and does not allow device self-assignment. Unset the channel and the device will automatically use the public channel."}当设备尝试将自己分配到不允许自我分配的频道时:
{ "status": "error", "error": "channel_self_set_not_allowed", "message": "This channel does not allow devices to self associate"}4. 取消频道分配(DELETE 请求)
标题为“4. 取消频道分配(DELETE 请求)”当插件调用 unsetChannel()时,它发送一个删除请求来移除设备的频道分配。
请求格式
标题为“请求格式”// DELETE /api/channel_selfinterface UnsetChannelRequest { device_id: string app_id: string platform: "ios" | "android" | "electron" plugin_version: string version_build: string version_code: string version_name: string}实现示例
名为“实现示例”的部分以下是 JavaScript 中如何实现渠道端点的示例代码:
interface ChannelRequest { device_id: string app_id: string channel?: string platform: "ios" | "android" | "electron" plugin_version: string version_build: string version_code: string version_name: string}
interface ChannelResponse { status: "ok" | "error" channel?: string allowSet?: boolean message?: string error?: string}
export const handler = async (event) => { const method = event.httpMethod || event.method const body = JSON.parse(event.body || '{}') as ChannelRequest
const { device_id, app_id, channel, platform } = body
try { switch (method) { case 'GET': return await getDeviceChannel(device_id, app_id)
case 'POST': return await setDeviceChannel(device_id, app_id, channel!, platform)
case 'DELETE': return await unsetDeviceChannel(device_id, app_id)
default: return { status: "error", error: "Method not allowed" } } } catch (error) { return { status: "error", error: error.message } }}
async function getDeviceChannel(deviceId: string, appId: string): Promise<ChannelResponse> { // Query your database for device channel assignment const assignment = await database.getDeviceChannel(deviceId, appId)
if (assignment) { return { status: "ok", channel: assignment.channel, allowSet: assignment.allowSelfAssign } }
// Return default channel if no assignment found return { status: "ok", channel: "production", // Your default channel allowSet: true }}
async function setDeviceChannel( deviceId: string, appId: string, channel: string, platform: string): Promise<ChannelResponse> { // Validate channel exists and allows self-assignment const channelConfig = await database.getChannelConfig(channel, appId)
if (!channelConfig) { return { status: "error", error: "Channel not found" } }
if (!channelConfig.allowDeviceSelfSet) { return { status: "error", error: "Channel does not allow self-assignment" } }
// Check platform restrictions if (platform === "ios" && !channelConfig.ios) { return { status: "error", error: "Channel not available for iOS" } }
if (platform === "android" && !channelConfig.android) { return { status: "error", error: "Channel not available for Android" } }
if (platform === "electron" && !channelConfig.electron) { return { status: "error", error: "Channel not available for Electron" } }
// Save the assignment await database.setDeviceChannel(deviceId, appId, channel)
return { status: "ok", message: "Device assigned to channel successfully" }}
async function unsetDeviceChannel(deviceId: string, appId: string): Promise<ChannelResponse> { // Remove device channel assignment await database.removeDeviceChannel(deviceId, appId)
return { status: "ok", message: "Device channel assignment removed" }}渠道配置
名为“渠道配置”的部分您的渠道系统应该支持这些配置选项:
interface ChannelConfig { name: string appId: string
// Platform targeting ios: boolean // Allow updates to iOS devices android: boolean // Allow updates to Android devices electron: boolean // Allow updates to Electron apps
// Device type restrictions allow_emulator: boolean // Allow updates on emulator/simulator devices allow_device: boolean // Allow updates on real/physical devices
// Build type restrictions allow_dev: boolean // Allow updates on development builds (is_prod=false) allow_prod: boolean // Allow updates on production builds (is_prod=true)
// Channel assignment public: boolean // Default channel - devices fall back to this when no override allowDeviceSelfSet: boolean // Allow devices to self-assign via setChannel()
// Update policies disableAutoUpdate: "major" | "minor" | "version_number" | "none" disableAutoUpdateUnderNative: boolean}设备过滤逻辑
名为“设备过滤逻辑”的部分当列出兼容渠道(GET 请求)时,您应该根据以下条件过滤渠道:
- 平台检查: 频道必须允许设备的平台 (
ios,android, 或electron) - 设备类型检查:
- 如果
is_emulator=true: 频道必须有allow_emulator=true - 如果
is_emulator=false: 频道必须有allow_device=true
- 如果
- 构建类型检查:
- 如果
is_prod=true: 频道必须有allow_prod=true - __CAPGO_KEEP_0__
is_prod=false: 必须有频道allow_dev=true
- 如果
- 可见性检查: 频道必须是
public=true或allow_device_self_set=true
// Example filtering logicfunction getCompatibleChannels( platform: 'ios' | 'android' | 'electron', isEmulator: boolean, isProd: boolean, channels: ChannelConfig[]): ChannelConfig[] { return channels.filter(channel => { // Platform check if (!channel[platform]) return false
// Device type check if (isEmulator && !channel.allow_emulator) return false if (!isEmulator && !channel.allow_device) return false
// Build type check if (isProd && !channel.allow_prod) return false if (!isProd && !channel.allow_dev) return false
// Must be accessible (public or self-assignable) if (!channel.public && !channel.allowDeviceSelfSet) return false
return true })}数据库架构示例
标题为“数据库架构示例”您需要存储频道配置和设备分配:
-- Channels tableCREATE TABLE channels ( id SERIAL PRIMARY KEY, name VARCHAR(255) NOT NULL, app_id VARCHAR(255) NOT NULL,
-- Platform targeting ios BOOLEAN DEFAULT true, android BOOLEAN DEFAULT true, electron BOOLEAN DEFAULT true,
-- Device type restrictions allow_emulator BOOLEAN DEFAULT true, -- Allow emulator/simulator devices allow_device BOOLEAN DEFAULT true, -- Allow real/physical devices
-- Build type restrictions allow_dev BOOLEAN DEFAULT true, -- Allow development builds allow_prod BOOLEAN DEFAULT true, -- Allow production builds
-- Channel assignment public BOOLEAN DEFAULT false, -- Default channel (fallback) allow_device_self_set BOOLEAN DEFAULT false, -- Allow self-assignment
-- Update policies disable_auto_update VARCHAR(50) DEFAULT 'none', disable_auto_update_under_native BOOLEAN DEFAULT false,
created_at TIMESTAMP DEFAULT NOW(), UNIQUE(name, app_id));
-- Device channel assignments tableCREATE TABLE device_channels ( id SERIAL PRIMARY KEY, device_id VARCHAR(255) NOT NULL, app_id VARCHAR(255) NOT NULL, channel_name VARCHAR(255) NOT NULL, assigned_at TIMESTAMP DEFAULT NOW(), UNIQUE(device_id, app_id));错误处理
标题为“错误处理”处理常见错误场景:
// Channel not found{ "status": "error", "error": "Channel 'beta' not found"}
// Self-assignment not allowed{ "status": "error", "error": "Channel does not allow device self-assignment"}
// Platform not supported{ "status": "error", "error": "Channel not available for this platform"}
// Invalid request{ "status": "error", "error": "Missing required field: device_id"}最佳实践
最佳实践- 安全性验证所有频道 assignments 与您的商业规则
- 日志记录所有频道操作以进行审计和调试
- 性能缓存频道配置以减少数据库查询
- 验证验证 device_id 和 app_id 真实性
- 速率限制: 实现速率限制以防止滥用
与更新的集成
标题:与更新的集成频道 assignments 与您的 更新 API 接口. 当设备请求更新时,检查其频道 assignments 以确定哪个版本应该提供:
async function getUpdateForDevice(deviceId: string, appId: string) { // Get device's channel assignment const channelAssignment = await getDeviceChannel(deviceId, appId) const channel = channelAssignment.channel || 'production'
// Get the version assigned to this channel const channelVersion = await getChannelVersion(channel, appId)
return { version: channelVersion.version, url: channelVersion.url, checksum: channelVersion.checksum }}这创建了一个完整的自托管频道管理系统,使您能够完全控制如何将更新分发给您的用户。
