HarmonyOS 鸿蒙Next eTS获取位置获取不到

HarmonyOs，远程模拟器，API8

代码如下：

import geolocation from '@ohos.geolocation'

@Entry
@Component
struct LocationTest {
  @State content: string = "位置测试"
  @State latitude: number = 0
  @State longitude: number = 0
  @State city: string = ''
  locationChange = async (location) => {
    this.latitude = location.latitude
    this.longitude = location.longitude
    if (this.longitude !== 0 && this.longitude !== 0) {
      console.info(`latitude = ${this.latitude}, longitude = ${this.longitude}`)
    }
  }

  async getLocation() {
    let requestInfo: geolocation.LocationRequest = {
      priority: 0x203,
      scenario: 0x300,
      timeInterval: 0,
      distanceInterval: 0,
      maxAccuracy: 0
    }
    geolocation.on('locationChange', requestInfo, this.locationChange)
  }

  build() {
    Column() {
      Button(this.content).fontSize(30).onClick(async () => {
        await this.getLocation()
      })
      Button(this.latitude.toString()).fontSize(30)
      Button(this.content).fontSize(30)
    }.justifyContent(FlexAlign.Center).width("100%").height("100%")
  }
}

权限如下：

"reqPermissions": [
  {
    "name": "ohos.permission.LOCATION",
  },
  {
    "name": "ohos.permission.LOCATION_IN_BACKGROUND"
  }
]
