频道API终点
复制一个带有安装步骤和完整 Markdown 指南的设置提示。
Capgo 中的通道是管理应用程序更新的核心机制。在自托管模式下,您需要实现通道端点来处理设备分配、通道查询和通道管理操作。
了解通道
标题为“了解通道”通道允许您:
- 控制更新分发: 为不同用户组分配不同的应用版本
- A/B测试: 使用特定用户段测试新功能
- 分阶段发布: 分阶段发布更新以降低风险
- 环境隔离: 将开发、测试和生产更新隔离
配置
配置配置渠道端点URL 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不同频道操作,端点需要处理:
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 listChannels(),它会发送一个GET请求来获取与设备兼容的所有频道。这将返回与设备环境(开发/生产,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
复制到剪贴板// 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}复制到剪贴板
__CAPGO_KEEP_0__[ { "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
关于了解通道类型的部分响应包含每个通道的两个重要标志:
-
public: true:这是一个 默认通道。设备无法自行将其分配到它使用setChannel()。相反,如果设备移除其通道分配(使用unsetChannel()),它将自动从公共通道接收更新,如果它匹配设备的条件。 -
allow_self_set: true:这是一个 可自行分配的通道。设备可以显式将其分配到此通道使用setChannel(). 适用于 beta 测试、A/B 测试或允许用户选择特定更新跟踪。
2. 获取通道 (PUT 请求)
标题为“2. 获取通道 (PUT 请求)”的部分当插件调用 getChannel(),它会发送一个 PUT 请求来检索设备的当前通道 assignments。
请求格式
标题为“请求格式”的部分// 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
响应格式部分:响应格式{ "status": "ok", "channel": "production", "allowSet": true, "message": "", "error": ""}3. 设置频道(POST 请求)
设置频道(POST 请求)部分:3. 设置频道(POST 请求)当插件调用时, 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
请求格式部分: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}{ "status": "ok", "message": "Device assigned to channel successfully", "error": ""}当设备尝试将自己分配到一个 公共频道 (一个有 public: true)时,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(DELETE 请求)
Section titled “4. 取消频道(DELETE Request)”当插件调用 unsetChannel(),它会发送一个DELETE请求来移除设备的频道分配。
// 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}以下是如何在JavaScript中实现频道端点的示例:
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" }}Your channel system should support these configuration options:
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
设备过滤逻辑当列出兼容的频道(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: 频道必须有allow_emulator=true - __CAPGO_KEEP_0__
is_emulator=false: Channel must haveallow_device=true
- 如果
- 构建类型检查:
- 如果
is_prod=true: Channel must haveallow_prod=true - 如果
is_prod=false: Channel must haveallow_dev=true
- 如果
- 可见性检查: Channel must be either
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
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: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"}

标题:最佳实践- 安全性:验证所有频道分配与您的商业规则
- 日志:为审计和调试目的记录所有频道操作
- 性能:缓存频道配置以减少数据库查询
- 验证:验证设备ID和应用ID的真实性
- 速率限制:防止滥用,实现速率限制
与更新的集成
节目标题:与更新的集成频道分配与您的 更新API端点当设备请求更新时,检查其频道分配以确定要服务的版本:
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 }}本系统创建了一个完整的自主管理的频道管理系统,允许您完全控制更新如何分发给您的用户。
