详情
语法	`apoc.util.decompress(data [, config ])`
描述	解压给定的字节数组。
参数	名称	类型	描述
	`data`	`BYTEARRAY`	要解压的数据字节数组。
	`config`	`MAP`	{ compression = "GZIP" :: ["GZIP", "BZIP2", "DEFLATE", "BLOCK_LZ4", "FRAMED_SNAPPY", "NONE"], charset = "UTF_8" ::["UTF-8", "UTF-16", "UTF-16BE", "UTF-16LE", "UTF-32", "US-ASCII", "ISO-8859-1"] } 默认值为：`{}`。
返回	`STRING`

配置参数

该过程支持以下配置参数

配置参数
名称	类型	默认值	描述
compression	枚举	GZIP	用于解压字节数组的压缩算法接受的值包括：GZIP, BZIP2, DEFLATE, BLOCK_LZ4, FRAMED_SNAPPY, NONE (即不压缩直接转换为字符串)
charset	枚举	UTF-8	用于解压字节数组的字符集接受的值包括：UTF-8, UTF-16, UTF-16BE, UTF-16LE, UTF-32, US-ASCII, ISO-8859-1

使用示例

WITH apoc.util.compress("Mätrix II 哈哈😄123", {charset: 'UTF-32'}) as compressed
RETURN apoc.util.decompress(compressed, {charset: 'UTF-32'}) AS value

结果
值
"Mätrix II 哈哈😄123"

WITH apoc.util.compress("Mätrix II 哈哈😄123", {compression: 'DEFLATE'}) as compressed
RETURN apoc.util.decompress(compressed, {compression: 'DEFLATE'}) AS value

结果
值
"Mätrix II 哈哈😄123"

WITH apoc.util.compress("Example", {charset: 'UTF-16'}) as compressed
RETURN apoc.util.decompress(compressed, {charset: 'UTF-16'}) AS value

结果
值
"Example"
