HarmonyOS 鸿蒙Next 消息广播报错
let notificationRequest = { id: 1, content: { contentType: notificationManager.ContentType.NOTIFICATION_CONTENT_BASIC_TEXT, normal: { title: “test_title”, text: “test_text”, additionalText: “test_additionalText” } } }; notificationManager.publish(notificationRequest).then(() => { console.info(“publish success”); }); Object literal must correspond to some explicitly declared class or interface (arkts-no-untyped-obj-literals) <ArkTSCheck> Argument of type ‘{ id: number; content: { contentType: notificationManager.ContentType; normal: { title: string; text: string; additionalText: string; }; }; }’ is not assignable to parameter of type ‘NotificationRequest’. The types of ‘content.contentType’ are incompatible between these types. Type ‘import("/Users/manssssay/Library/Huawei/Sdk/HarmonyOS-NEXT-DP2/base/ets/api/@ohos.notificationManager").default.ContentType’ is not assignable to type ‘import("/Users/manssssay/Library/Huawei/Sdk/HarmonyOS-NEXT-DP2/base/ets/api/@ohos.notification").default.ContentType’. Property ‘NOTIFICATION_CONTENT_SYSTEM_LIVE_VIEW’ is missing in type ‘import("/Users/manssssay/Library/Huawei/Sdk/HarmonyOS-NEXT-DP2/base/ets/api/@ohos.notification").default.ContentType’. <ArkTSCheck> Argument of type ‘{ id: number; content: { contentType: notificationManager.ContentType; normal: { title: string; text: string; additionalText: string; }; }; }’ is not assignable to parameter of type ‘NotificationRequest’. <ArkTSCheck> 直接复制官方api示例, 直接报错, 应该是11版本语法检查有误, 请告知现版本该如何操作, 另官方文档能否更新?

试一下如下代码:
// 发布基本类型通知
publishBasicNotification(){
let notificationRequest: notificationManager.NotificationRequest = {
id: 1,
notificationSlotType : notificationManager.SlotType.SOCIAL_COMMUNICATION,
content: {
notificationContentType: notificationManager.ContentType.NOTIFICATION_CONTENT_BASIC_TEXT, //普通文本类型通知
normal: {
title: '基本型消息通知',
text: '通知内容balabala',
additionalText: 'test_additionalText',
}
}
};
notificationManager.publish(notificationRequest, (err:Base.BusinessError) => {
if (err) {
console.error(`Failed to publish notification. Code is ${err.code}, message is ${err.message}`);
return;
}
console.info('Succeeded in publishing notification.');
});
}
针对您提到的HarmonyOS 鸿蒙Next消息广播报错问题,这通常与配置、网络权限或系统兼容性有关。以下是一些可能的解决方案:
- 检查配置:请确保UDP广播的IP地址和端口号配置正确,且广播地址符合网络规范。这通常是解决广播无法接收消息的首要步骤。
- 网络权限:确保您的应用已获取必要的网络权限,特别是接收UDP广播的权限。在鸿蒙系统中,您可以在应用的网络权限设置中检查并调整相关权限。
- 系统更新:尝试将鸿蒙系统更新至最新版本,以解决可能存在的系统兼容性问题。
- 查看日志:通过查看系统日志或应用日志,您可能能够找到导致广播报错的更具体信息。
如果以上步骤均无法解决问题,可能是由于更深层次的系统或应用问题。此时,建议您联系官网客服以获取更专业的帮助。官网地址是:https://www.itying.com/category-93-b0.html 。在联系客服时,请提供详细的错误信息和设备配置,以便快速定位问题。
