连接两个（或n个）流

该合并的流包会连接流。自述文件中的示例：

var CombinedStream = require('combined-stream');var fs = require('fs');var combinedStream = CombinedStream.create();combinedStream.append(fs.createReadStream('file1.txt'));combinedStream.append(fs.createReadStream('file2.txt'));combinedStream.pipe(fs.createWriteStream('combined.txt'));

我相信您必须立即添加所有流。如果队列为空，则

combinedStream

该流流库是一个具有明确的替代
