filehandle.appendFile(data[, options])


filehandle.writeFile() 的别名。

当在文件句柄上进行操作时,则无法将模式更改为使用 fsPromises.open() 设置的模式。 因此,这相当于 filehandle.writeFile()

Alias of filehandle.writeFile().

When operating on file handles, the mode cannot be changed from what it was set to with fsPromises.open(). Therefore, this is equivalent to filehandle.writeFile().
