返回:
<string>
|
<Buffer>
返回
path
的内容。
有关详细信息，请参阅此 API 的异步版本的文档：
fs.readFile()
。
如果指定了
encoding
选项，则此函数返回字符串。
否则它返回缓冲区。
与
fs.readFile()
类似，当路径为目录时，
fs.readFileSync()
的行为是特定于平台的。
import { readFileSync } from 'node:fs';
readFileSync('<directory>');
readFileSync('<directory>');

If the
encoding
option is specified then this function returns a
string. Otherwise it returns a buffer.
Similar to
fs.readFile()
, when the path is a directory, the behavior of
fs.readFileSync()
is platform-specific.
import { readFileSync } from 'node:fs';
readFileSync('<directory>');
readFileSync('<directory>');
