ConnectOptions
在毗连指定的配景服务时作为入参，用于吸收毗连过程中的状态变革，如作为connectServiceExtensionAbility的入参，毗连指定的ServiceExtensionAbility。
说明
本模块首批接口从API version 7开始支持。后续版本的新增接口，采用上角标单独标志接口的起始版本。
导入模块
import { common } from '@kit.AbilityKit'; onConnect
onConnect(elementName: ElementName, remote: rpc.IRemoteObject): void
创建毗连时的回调函数。
体系能力：SystemCapability.Ability.AbilityRuntime.Core
参数：
参数名类型必填说明elementNameElementName是Ability的elementName。remoterpc.IRemoteObject是IRemoteObject实例。 示例：
import { UIAbility, common, Want, AbilityConstant } from '@kit.AbilityKit';
import { bundleManager } from '@kit.AbilityKit';
import { rpc } from '@kit.IPCKit';
let connectWant: Want = {
bundleName: 'com.example.myapp',
abilityName: 'MyAbility'
};
let connectOptions: common.ConnectOptions = {
onConnect(elementName: bundleManager.ElementName, remote: rpc.IRemoteObject) {
console.log(`onConnect elementName: ${elementName}`);
},
onDisconnect(elementName: bundleManager.ElementName) {
console.log(`onDisconnect elementName: ${elementName}`);
},
onFailed(code: number) {
console.error(`onFailed code: ${code}`);
}
};
class EntryAbility extends UIAbility {
onCreate(want: Want, launchParam: AbilityConstant.LaunchParam) {
let connection: number = this.context.connectServiceExtensionAbility(connectWant, connectOptions);
}
} onDisconnect
onDisconnect(elementName: ElementName): void
断开毗连时的回调函数。
体系能力：SystemCapability.Ability.AbilityRuntime.Core
参数：
参数名类型必填说明elementNameElementName是Ability的elementName。 示例：
import { UIAbility, common, Want, AbilityConstant } from '@kit.AbilityKit';
import { bundleManager } from '@kit.AbilityKit';
import { rpc } from '@kit.IPCKit';
let connectWant: Want = {
bundleName: 'com.example.myapp',
abilityName: 'MyAbility'
};
let connectOptions: common.ConnectOptions = {
onConnect(elementName: bundleManager.ElementName, remote: rpc.IRemoteObject) {
console.log(`onConnect elementName: ${elementName}`);
},
onDisconnect(elementName: bundleManager.ElementName) {
console.log(`onDisconnect elementName: ${elementName}`);
},
onFailed(code: number) {
console.error(`onFailed code: ${code}`);
}
};
class EntryAbility extends UIAbility {
onCreate(want: Want, launchParam: AbilityConstant.LaunchParam) {
let connection: number = this.context.connectServiceExtensionAbility(connectWant, connectOptions);
}
} onFailed
onFailed(code: number): void
毗连失败时的回调函数。
体系能力：SystemCapability.Ability.AbilityRuntime.Core
参数：
参数名类型必填说明codenumber是 毗连指定Ability返回的结果code。
值为0表现毗连乐成，值为-1表现参数错误，值为-2表现未找到对应Ability。
示例：
import { UIAbility, common, Want, AbilityConstant } from '@kit.AbilityKit';
import { bundleManager } from '@kit.AbilityKit';
import { rpc } from '@kit.IPCKit';
let connectWant: Want = {
bundleName: 'com.example.myapp',
abilityName: 'MyAbility'
};
let connectOptions: common.ConnectOptions = {
onConnect(elementName: bundleManager.ElementName, remote: rpc.IRemoteObject) {
console.log(`onConnect elementName: ${elementName}`);
},
onDisconnect(elementName: bundleManager.ElementName) {
console.log(`onDisconnect elementName: ${elementName}`);
},
onFailed(code: number) {
console.error(`onFailed code: ${code}`);
}
};
class EntryAbility extends UIAbility {
onCreate(want: Want, launchParam: AbilityConstant.LaunchParam) {
let connection: number = this.context.connectServiceExtensionAbility(connectWant, connectOptions);
}
