> hvigor ERROR: 'import' and 'export' may only appear at the top level (Note that you need plugins to import files that are not JavaScript)

好像是说某个插件(库)支持动态导入。只能在文件顶层(开头)导入导出

你好,看报错信息应该是module.json5中没有配置ohos.permission.INTERNET 权限。如果方便的话可以提供一下复现的demo方便定位问题。

{ “name”: “weather”, “type”: “entry”, “description”: “$string:module_desc”, “mainElement”: “MainAbility”, “deviceTypes”: [ “phone”, “tablet” ], “deliveryWithInstall”: true, “installationFree”: false, “pages”: “$profile:main_pages”, “metadata”: [ { “name”: “ohos.weather.api.version”, “value”: “1.0” } ], “abilities”: [ { “name”: “MainAbility”, “srcEntry”: “./ets/MainAbility/MainAbility.ets”, “description”: “$string:mainability_desc”, “icon”: “$media:icon”, “label”: “$string:app_name”, “startWindowIcon”: “$media:icon”, “startWindowBackground”: “$color:start_background”, “visible”: true, “skills”: [ { “actions”: [ “action.system.home” ], “entities”: [ “entity.system.home” ] } ] } ], “requestPermissions”: [ { “name”: “ohos.permission.INTERNET”, “reason”: “$string:internet_permission_reason”, “usedScene”: { “ability”: [“MainAbility”], “when”: “always” } }, { “name”: “ohos.permission.LOCATION”, “reason”: “$string:location_permission_reason”, “usedScene”: { “ability”: [“MainAbility”], “when”: “inuse” } } ] }

在HarmonyOS鸿蒙Next中编写天气程序时,出现的错误码可能与系统API调用、资源管理、权限设置或网络请求相关。以下是一些常见的错误码及其可能的原因:

  1. 错误码:200
    通常表示操作成功,但如果你在调试过程中遇到此错误码,可能是某些逻辑判断未正确处理成功后的流程。

  2. 错误码:401
    表示未授权,可能是访问某些API时未正确配置权限或未通过身份验证。检查config.json文件中的权限声明,确保已添加必要的权限。

  3. 错误码:403
    表示禁止访问,可能是请求的资源或API未对当前应用开放。检查API调用是否符合鸿蒙系统的访问规则。

  4. 错误码:404
    表示资源未找到,可能是请求的API路径或资源文件路径错误。检查代码中的路径配置是否正确。

  5. 错误码:500
    表示服务器内部错误,可能是后端服务出现问题或请求参数不符合预期。检查网络请求的参数和格式。

  6. 错误码:100001
    表示系统内部错误,可能是鸿蒙系统API调用失败或资源管理异常。检查API调用是否符合鸿蒙开发规范。

  7. 错误码:100002
    表示参数错误,可能是传递给API的参数不符合要求。检查参数类型、格式和取值范围。

  8. 错误码:100003
    表示内存不足,可能是应用占用了过多内存资源。优化代码,减少内存消耗。

  9. 错误码:100004
    表示文件操作失败,可能是文件路径错误或权限不足。检查文件路径和权限设置。

  10. 错误码:100005
    表示网络连接失败,可能是网络配置错误或网络不可用。检查网络连接状态和配置。

根据具体的错误码,结合代码逻辑和鸿蒙开发文档,定位问题并修复。

在HarmonyOS鸿蒙Next中编写天气程序时,错误码通常与API调用、权限设置或网络连接有关。请提供具体的错误码,以便更准确地分析问题。常见错误码如1001(权限不足)、2001(网络连接失败)或3001(API调用错误),建议检查权限配置、网络状态及API调用参数。
