HarmonyNote.TOP鸿蒙开发笔记

kit.NetworkKit的http模块实践

开发鸿蒙应用,网络请求少不了,在ArkTs语言中,可使用原生的@kit.NetworkKit中的http模块来实现GET或POST请求,当然也可以使用axios模块。初次在鸿蒙应用中使用http模块,可能会报如下错误:

To use this API, you need to apply for the permissions: ohos.permission.INTERNET <ArkTSCheck>

这是因为应用没有获得网络请求权限,需要在/ProjectDir/entry/src/main/module.json5中配置网络请求权限,添加如下代码实现:

"requestPermissions": [
{
  "name": "ohos.permission.INTERNET"
}
],

添加配置代码后,会提示Core configuration attributes have changed since last project sync,A project sync may be necessary for the IDE to work properly,点击Sync Now即可

完整的module.json5配置示例如下:

{
  "module": {
    "name": "entry",
    "type": "entry",
    "description": "$string:module_desc",
    "mainElement": "EntryAbility",
    "deviceTypes": [
      "phone",
      "tablet",
      "2in1"
    ],

    "installationFree": false,
    "pages": "$profile:main_pages",
    "requestPermissions": [
      {
        "name": "ohos.permission.INTERNET"
      }
    ],

            ],
            "actions": [
              "action.system.home"
            ]
          }
        ]
      }
    ],
    "extensionAbilities": [
      {
        "name": "EntryBackupAbility",
        "srcEntry": "./ets/entrybackupability/EntryBackupAbility.ets",
        "type": "backup",
        "exported": false,
        "metadata": [
          {
            "name": "ohos.extension.backup",
            "resource": "$profile:backup_config"
          }
        ],
      }
    ]
  }
