The mongo客户端字段级加密方法要求数据库连接启用客户端字段级的加密。mongo client-side field level encryption methods require a database connection with client-side field level encryption enabled. If the current database connection was not initiated with client-side field level encryption enabled, either:如果当前数据库连接未在启用客户端字段级加密的情况下启动，请执行以下任一操作：
Use the 使用Mongo shell中的Mongo() constructor from the mongo shell to establish a connection with the required client-side field level encryption options. Mongo()构造函数建立与所需客户端字段级加密选项的连接。The Mongo() method supports the following Key Management Service (KMS) providers for Customer Master Key (CMK) management:Mongo()方法支持以下用于客户主密钥（CMK）管理的密钥管理服务（KMS）提供程序：
