您在module.json5里面配置了相应的权限了吗？[https://developer.harmonyos.com/cn/docs/documentation/doc-guides-V3/accesstoken-guidelines-0000001493744016-V3]

配置了，如下：

  • "name" : "ohos.permission.INTERNET"

    • "reason": "$string:network_permission_reason"
    • "usedScene": { "abilities": ["EntryAbility"], "when": "always" }

  • "name" : "ohos.permission.GET_NETWORK_INFO"

    • "reason": "$string:network_permission_reason"
    • "usedScene": { "abilities": ["EntryAbility"], "when": "always" }

  • "name" : "ohos.permission.APPROXIMATELY_LOCATION"

    • "reason": "$string:location_permission_reason"
    • "usedScene": { "abilities": ["EntryAbility"], "when": "always" }

  • "name" : "ohos.permission.LOCATION"

    • "reason": "$string:location_permission_reason"
    • "usedScene": { "abilities": ["EntryAbility"], "when": "always" }

  • "name" : "ohos.permission.LOCATION_IN_BACKGROUND"

    • "reason": "$string:location_permission_reason"
    • "usedScene": { "abilities": ["EntryAbility"], "when": "always" }

  • "name" : "ohos.permission.READ_MEDIA"

    • "reason": "$string:media_access_permission_reason"
    • "usedScene": { "abilities": ["EntryAbility"], "when": "always" }

  • "name" : "ohos.permission.WRITE_MEDIA"

    • "reason": "$string:media_access_permission_reason"
    • "usedScene": { "abilities": ["EntryAbility"], "when": "always" }

  • "name" : "ohos.permission.ACCESS_NOTIFICATION_POLICY"

    • "reason": "$string:media_access_permission_reason"
    • "usedScene": { "abilities": ["EntryAbility"], "when": "always" }

请问楼主这个问题解决了吗，如何解决的呢？我也出现了这个问题，使用

requestPermissionsFromUser()方法，但是并没有出现授权弹窗，目前我是使用的API9,并且基于arkts语法。

怀疑跟这个权限有关，去掉后可以弹窗

"name": "ohos.permission.LOCATION_IN_BACKGROUND",

但后台定位权限需要申请怎么办呢？

我去掉这个也没有弹窗，只能手动加动态授权弹窗，不知道怎么搞，

回复的格式真是太不友好了，重新发一个

```bash
"requestPermissions": [
  {
    "name" : "ohos.permission.INTERNET",
    "reason": "${string}:network_permission_reason",
    "usedScene": {
      "abilities": [
        "EntryAbility"
      ],
      "when": "always"
    }
  },
  {
    "name" : "ohos.permission.GET_NETWORK_INFO",
    "reason": "${string}:network_permission_reason",
    "usedScene": {
      "abilities": [
        "EntryAbility"
      ],
      "when": "always"
    }
  },
  {
    "name" : "ohos.permission.APPROXIMATELY_LOCATION",
    "reason": "${string}:location_permission_reason",
    "usedScene": {
      "abilities": [
        "EntryAbility"
      ],
      "when": "always"
    }
  },
  {
    "name" : "ohos.permission.LOCATION",
    "reason": "${string}:location_permission_reason",
    "usedScene": {
      "abilities": [
        "EntryAbility"
      ],
      "when": "always"
    }
  },
  {
    "name" : "ohos.permission.LOCATION_IN_BACKGROUND",
    "reason": "${string}:location_permission_reason",
    "usedScene": {
      "abilities": [
        "EntryAbility"
      ],
      "when": "always"
    }
  },
  {
    "name" : "ohos.permission.READ_MEDIA",
    "reason": "${string}:media_access_permission_reason",
    "usedScene": {
      "abilities": [
        "EntryAbility"
      ],
      "when": "always"
    }
  },
  {
    "name" : "ohos.permission.WRITE_MEDIA",
    "reason": "${string}:media_access_permission_reason",
    "usedScene": {
      "abilities": [
        "EntryAbility"
      ],
      "when": "always"
    }
  },
  {
    "name" : "ohos.permission.ACCESS_NOTIFICATION_POLICY",
    "reason": "${string}:media_access_permission_reason",
    "usedScene": {
      "abilities": [
        "EntryAbility"
      ],
      "when": "always"
    }
  }
]

在HarmonyOS鸿蒙Next中，应用无法自动弹窗且权限申请失败，可能是由于以下原因：

  1. 权限声明缺失：在config.json文件中未正确声明所需权限。例如，如果需要访问位置信息，应在config.json中声明ohos.permission.LOCATION权限。

  2. 权限申请时机不当：权限申请应在应用启动后的合适时机进行，通常在onStart或onActive生命周期方法中。如果权限申请过早或过晚，可能导致弹窗无法正常显示。

  3. 权限申请方式错误：使用requestPermissionsFromUser方法申请权限时，需确保传入的权限数组正确，并且调用时机合适。例如：

    let permissions: Array<string> = ['ohos.permission.LOCATION'];
requestPermissionsFromUser(permissions).then((data) => {
    console.log('Permission request result:', data);
}).catch((error) => {
    console.error('Permission request failed:', error);
});

  4. 系统权限设置：用户可能在系统设置中手动关闭了应用的权限，导致权限申请失败。需引导用户检查系统设置中的权限管理。

  5. 设备兼容性问题：某些设备可能对权限申请的处理方式不同，导致弹窗无法正常显示。需在不同设备上进行测试，确保兼容性。

  6. 应用签名问题：如果应用未正确签名，可能导致权限申请失败。需确保应用已正确签名并安装。

  7. 系统版本问题：鸿蒙Next版本可能存在权限管理机制的差异，需确认应用在目标系统版本上的兼容性。

检查以上问题后，重新测试应用权限申请功能。

在HarmonyOS鸿蒙Next中，应用无法自动弹窗且权限申请失败，可能原因包括：

  1. 未在config.json中正确声明所需权限；

  2. 未在代码中调用requestPermissionsFromUser方法；

  3. 设备设置中禁用了相关权限。

请检查权限声明、调用逻辑及设备设置，确保权限申请流程正确执行。
