鸿蒙应用已经在module.json5添加了"name": "ohos.permission.INTERNET权限在真机运行时还是显示没有权限

"requestPermissions": [{
      "name": "ohos.permission.INTERNET",
    }, {
      "name": "ohos.permission.FILE_ACCESS_PERSIST"
    },
      {
        "name": "ohos.permission.READ_MEDIA",
        "reason": "$string:READ_MEDIA_reason",
        "usedScene": {
          "abilities": [
            "EntryAbility"
          ],
          "when": "inuse"
        }
      },
      {
        "name": "ohos.permission.WRITE_MEDIA",
        "reason": "$string:WRITE_MEDIA_reason",
        "usedScene": {
          "abilities": [
            "EntryAbility"
          ],
          "when": "inuse"
        }
      }],

数据请求方法

export function getVodData(url: string): Promise<string> {
  return new Promise((resolve, reject) => {
    console.log("kaishi请求数据")//1

    let httpRequest = http.createHttp();
    let options: http.HttpRequestOptions = {
      method: http.RequestMethod.GET,
      expectDataType: http.HttpDataType.STRING,
    };
    httpRequest.request(urlRoot+url, options)
      .then((response) => {
        const vodStr = response.result.toString();
        createVodDataFile("/vodDB.db", vodStr);

        console.log("请求成功请求数据")//2
        resolve(vodStr);
      })
      .catch((err: Error) => {
        console.log("err:" + err);
        console.log("vodData请求数据shibai")//3
        reject(err);
      })
      .finally(() => {
        httpRequest.destroy();
      });
  });
}

运行结果还是报错

怎么样才能请求到数据呀

可以参考以下链接：https://developer.huawei.com/consumer/cn/forum/topic/02041746...
仅在module.json5中添加"name": "ohos.permission.INTERNET"权限后，使用如下Demo测试，没有出现权限拒绝报错；其中不包含createVodDataFile，麻烦检查下createVodDataFile方法中是否包含其他需要权限的操作，可以使用debug调试方式查看下：
测试demo：
import { http } from '@kit.NetworkKit';
import { ToastUtil } from '@pura/harmony-utils';

export function getVodData(url: string): Promise<string> {
return new Promise((resolve, reject) => {

console.log("kaishi请求数据")//1

let httpRequest = http.createHttp();
let options: http.HttpRequestOptions = {
  method: http.RequestMethod.GET,
  expectDataType: http.HttpDataType.STRING,
};
httpRequest.request(url, options)
  .then((response) => {
    const vodStr = response.result.toString();
    // createVodDataFile("/vodDB.db", vodStr);
    ToastUtil.showToast("调用成功")
    resolve(vodStr);
  })
  .catch((err: Error) => {
    ToastUtil.showToast("调用失败")
    reject(err);
  })
  .finally(() => {
    httpRequest.destroy();
  });

});
}

@Entry
@Component
struct HttpRequestDemo {
@State message: string = 'Hello World';

build() {

RelativeContainer() {
  Button(this.message)
    .id('HttpRequestDemoHelloWorld')
    .fontSize(50)
    .fontWeight(FontWeight.Bold)
    .alignRules({
      center: { anchor: '__container__', align: VerticalAlign.Center },
      middle: { anchor: '__container__', align: HorizontalAlign.Center }
    })
    .onClick(() => {
      getVodData("https://www.baidu.com/")
    })
}
.height('100%')
.width('100%')

}
}
