Capgo 中的频道是管理应用程序更新的核心机制。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: 将不同应用程序版本分配给不同用户组
- A/B 测试: 在特定用户群体中测试新功能
- 阶段性发布: 分阶段发布更新以降低风险
- 环境隔离: 将开发、测试和生产更新分开
配置
标题:配置在您的 capacitor.config.json:
{ "plugins": { "CapacitorUpdater": { "channelUrl": "https://myserver.com/api/channel_self" } }}频道操作
标题:频道操作插件执行以下频道操作,需要您的端点处理:
1. 列出兼容频道(GET 请求)
1. 列出兼容的频道(GET 请求)当插件调用时 listChannels()它会发送一个 GET 请求来检索与设备兼容的所有频道。该请求返回与设备环境(dev/prod,模拟器/真实设备)匹配的频道,并允许公共访问或自我分配。
请求格式
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
响应格式[ { "id": 1, "name": "production", "public": true, "allow_self_set": false }, { "id": 2, "name": "beta", "public": false, "allow_self_set": true }]了解频道类型
响应中包含每个频道的两个重要标志:__CAPGO_KEEP_0__
-
public: true: 这是 default channel. 设备无法自行将其分配到该频道中使用setChannel(). 相反,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 自行分配频道. 设备可以显式将其分配到该频道中使用setChannel()。这对于测试、A/B测试或允许用户选择特定更新轨迹非常有用。
2. 获取频道(PUT 请求)
标题:2. 获取频道(PUT 请求)当插件调用 getChannel(),它会发送一个 PUT 请求来获取设备当前的频道分配。
请求格式
复制到剪贴板// 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}标题:响应格式
复制到剪贴板{ "status": "ok", "channel": "production", "allowSet": true, "message": "", "error": ""}3. 设定频道 (POST 请求)
标题: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。
请求格式
标题:请求格式// 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}响应格式
标题:响应格式{ "status": "ok", "message": "Device assigned to channel successfully", "error": ""}错误案例
标题:错误案例When a device tries to assign itself to a __CAPGO_KEEP_0__ __CAPGO_KEEP_0__ (one with __CAPGO_KEEP_1__) public: trueyour endpoint should return an error:
{ "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."}When a device tries to assign itself to a channel that doesn’t allow self-assignment:
{ "status": "error", "error": "channel_self_set_not_allowed", "message": "This channel does not allow devices to self associate"}4. 取消频道(DELETE Request)
标题:4. 取消频道(DELETE Request)When the plugin calls __CAPGO_KEEP_2__ unsetChannel(), it sends a DELETE request to remove the device’s channel assignment.
请求格式
节标题: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
节标题:实现示例以下是 JavaScript 中如何实现通道端点的示例代码:
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" }}通道配置
节标题:通道配置您的通道系统应支持以下配置选项:
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
节标题:设备过滤逻辑列出兼容的频道 (GET 请求) 时,您应该根据以下条件过滤频道:
- 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: 频道必须具有allow_emulator=true - 如果
is_emulator=false: 频道必须具有allow_device=true
- 如果
- 构建类型检查:
- 如果
is_prod=true: 频道必须具有allow_prod=true - If
is_prod=false: Channel 必须有allow_dev=true
- 如果
- Visibility 检查: Channel 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:数据库架构示例您需要存储通道配置和设备 assignments:

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。
