我遇到了将代码文件写入Gridfs的代码段,但是我无法找到将字符串更新为Gridfs的写入方法。
下面的代码片段将使用path更新,但是直接字符串缓冲区呢?

var metadata = {
    "path": path
};
var writestream = gfs.createWriteStream({
    filename: name,
    mode: 'w',
    content_type: type,
    metadata: metadata
});
fs.createReadStream(path).pipe(writestream);
//    var buf = new Buffer("hello");
writestream.on('close', function (file) {
    console.log("Gridfs created");
});

最佳答案

即使已经有一段时间了。我遇到了这个问题,并解决了它从字符串而不是文件创建流的问题。
像这样:

  var writestream = gfs.createWriteStream({
      filename: fileName
  });

  // Create stream with buffer to pipe to writestream
  var s = new stream.Readable();
  s.push(pic);
  s.push(null); // Push null to end stream
  s.pipe(writestream);

  writestream.on('close', function (file) {
    // Do anything with the file
    cb(null, file.filename);
  }).on('error', cb);


here获得了流创意
