zlib.bytesRead

• <number>

弃用的 zlib.bytesWritten 别名。 选择这个原始名称是因为将值解释为引擎读取的字节数也是有意义的，但与 Node.js 中以这些名称公开值的其他流不一致。

• <number>

Deprecated alias for zlib.bytesWritten. This original name was chosen because it also made sense to interpret the value as the number of bytes read by the engine, but is inconsistent with other streams in Node.js that expose values under these names.
