比如下面的代码
stream 在使用后就会被消费掉,但是我想多次操作这个stream,该怎么解决呢,我下面的代码是通过fs方式再次获得,但是io太过于频繁了
const stream = await ctx.getFileStream(); const fs = require('fs'); const qhash = '123123'; // 写文件 await new Promise(resolve => stream .pipe(fs.createWriteStream(`upload/${qhash}.zip`)) .on('finish', resolve)); getManifest(`upload/${qhash}.zip`); const stream2 = await fs.createReadStream(`upload/${qhash}.zip`); const sssssshash = await qetag(stream2); const stream3 = await fs.createReadStream(`upload/${qhash}.zip`); // console.log(buffer);
