跳转代码：
context = getContext(this) as common.UIAbilityContext
let want = {
deviceId: "",
'bundleName': this.context.abilityInfo.bundleName,
'abilityName': 'TestAbility',
'moduleName': ''
};
this.context.startAbility(want).then(() => {
console.log(`页面跳转成功`)
}).catch((err) => {
console.log(`页面跳转错误 message: ${JSON.stringify(err.message)}`+' code: '+JSON.stringify(err.code))
})
