例子

使用注意事项

  • 该AttributeDecompressor使用zlib库提供基本的压缩和OpenSSL库提供加密。
  • 当加密数据写入数据库,最好使用BLOB数据类型。这种方式,数据总是存储在一个二进制数据类型,并且可以由AttributeDecompressor进行解密。如果数据库字段类型是一个字符串,那么你应该使用BinaryEncoder写作(二进制值转换为字符串)之前变压器和BinaryDecodertransformer after reading (to convert the string back to a binary value capable of being decrypted by the AttributeDecompressor).

Defining Values

There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters. There are a number of tools and shortcuts that can assist in constructing values, generally available from the drop-down context menu adjacent to the value field.
