await 对此表达式类型没有影响?

onChangeFlockData: function (e) {
    let tempArr = [];
    let imgUrls = e.detail.all;
    imgUrls.forEach(async(item) => {
      tempArr.push(item.url)

        this.imgInfoCheck(item.url)
      } else {
        await this.imgSecCheck(item.url)
      }
    });
    this.setData({
      tempArr: tempArr
    })
    console.log("tempArr:::", this.data.tempArr)
  },

imgSecCheck: function (tempUrl) {
    wx.showLoading({
      mask: true
    });
    wx.getFileSystemManager().readFile({
      filePath: tempUrl,
      encoding: "base64",
      success: res => {
