我正在尝试使用 调整图像大小sharp，版本是"sharp": "^0.23.0"。我使用了来自 的示例代码functions-samples。我的代码在这里

thumbnailGeneratorSharp: async (object) => {
    const fileBucket = object.bucket; // The Storage bucket that contains the file.
    const filePath = object.name; // File path in the bucket.
    const contentType = object.contentType; // File content type.

    // Exit if this is triggered on a file that is not an image.
    if (!contentType.startsWith('image/')) {
      console.log('This is not an image.');
      return null;
    }

    // Get the file name.
    const fileName = path.basename(filePath);
    // …

我试图使用以下代码将 blob 转换为字符串：

ResultSet rs = stmt.executeQuery(query);

Blob newValueBLOB = rs.getBlob("NEW_VALUE");
System.out.println(newValueBLOB);
String newValue = new String(newValueBLOB.getBytes(0, (int) newValueBLOB.length()));

我的数据库是 Oracle 并且连接已正确建立。我找到了类似的答案，但我的不起作用！

我尝试使用以下命令进行安装，我的节点版本opencv4nodejs是Ubuntu-20.04v12.19.0

sudo npm i -g opencv4nodejs\n

但出现这些错误

我试图使用 requestConfiguration 设置我的测试设备 ID。为了检查测试设备的设置是否成功，我logcat在 android studio 中进行了过滤setTestDeviceIds，但它向我显示了以下日志

2021-03-31 04:17:36.907 27185-27185/? I/Ads: Use RequestConfiguration.Builder().setTestDeviceIds(Arrays.asList("xxxxxxxxxxxxxxxxxxx")) to get test ads on this device.\n

因此，测试设备的设置不起作用，我无法使用真实的广告进行测试。当我传递 testDeviceId 时，该日志应该不会出现。您可以看到我正在testDeviceId为 inRequestConfiguration和传递 \'s bannerAd。

重现步骤

这是我的main.dart文件

这是我的adhelper.dart文件

我正在尝试执行一些顺序异步操作。但得到错误：

解析错误：意外的令牌管理员

虽然我已经声明了这个变量。这是我的代码

const admin = require('firebase-admin')
module.exports = {
   notificationCount: async (change, context) => {
    countRef.collection("notification").doc(context.params.reqID).get().then((requestDoc) => {
      console.log("Request Info " + requestDoc.data().reqUserName)
      return requestDoc.data();
    }).then((requestDocData) => {

      const token = await admin.database().ref("/UserInfo/" + notifiedUserID + "/token").once('value');
      console.log("UserInfo "+token);
      return null;

    }).catch((error) => {
      console.log("Loading failed: ", error);
    });
  }
}
