Use Automatic Queryable Encryption with GCP在GCP中使用自动可查询加密

• kmsProviderName - The KMS you're using to store your Customer Master Key. Set this variable to "gcp" for this tutorial.用于存储客户主键的KMS。在本教程中将此变量设置为"gcp"。

• uri - Your MongoDB deployment connection URI. 您的MongoDB部署连接URI。Set your connection URI in the MONGODB_URI environment variable or replace the value directly.在MONGODB_URI环境变量中设置连接URI或直接替换该值。

• keyVaultDatabaseName - The database in MongoDB where your data encryption keys (DEKs) will be stored. Set this variable to "encryption".MongoDB中存储数据加密键（DEK）的数据库。将此变量设置为"encryption"。

• keyVaultCollectionName - The collection in MongoDB where your DEKs will be stored. Set this variable to "__keyVault".MongoDB中存储您的DEK的集合。将此变量设置为"__keyVault"。

• keyVaultNamespace - The namespace in MongoDB where your DEKs will be stored. Set this variable to the values of the keyVaultDatabaseName and keyVaultCollectionName variables, separated by a period.MongoDB中存储DEK的命名空间。将此变量设置为keyVaultDatabaseName和keyVaultCollectionName变量的值，用句点分隔。

• encryptedDatabaseName - The database in MongoDB where your encrypted data will be stored. Set this variable to "medicalRecords".MongoDB中存储加密数据的数据库。将此变量设置为"medicalRecords"。

• encryptedCollectionName - The collection in MongoDB where your encrypted data will be stored. Set this variable to "patients".MongoDB中存储加密数据的集合。将此变量设置为"patients"。

You can declare these variables by using the following code:您可以使用以下代码声明这些变量：

// KMS provider name should be one of the following: "aws", "gcp", "azure", "kmip" or "local"
const kmsProviderName = "<Your KMS Provider Name>";

const uri = process.env.MONGODB_URI; // Your connection URI

const keyVaultDatabaseName = "encryption";
const keyVaultCollectionName = "__keyVault";
const keyVaultNamespace = `${keyVaultDatabaseName}.${keyVaultCollectionName}`;
const encryptedDatabaseName = "medicalRecords";
const encryptedCollectionName = "patients";

Create a sample document that describes a patient's personal information. Use the encrypted client to insert it into the patients collection, as shown in the following example:创建描述患者个人信息的示例文档。使用加密客户端将其插入patients集合，如以下示例所示：

const patientDocument = {
  patientName: "Jon Doe",
  patientId: 12345678,
  patientRecord: {
    ssn: "987-65-4320",
    billing: {
      type: "Visa",
      number: "4111111111111111",
    },
  },
};

const encryptedCollection = encryptedClient
  .db(encryptedDatabaseName)
  .collection(encryptedCollectionName);

const result = await encryptedCollection.insertOne(patientDocument);

const findResult = await encryptedCollection.findOne({
  "patientRecord.ssn": "987-65-4320",
});
console.log(findResult);
