Mongo gridfs-stream

Question

这是我的第一个gridfs-stream工作。我正在尝试从我的本地目录（C：\ work \ node \ test.txt）读取文件并将其写入gridfs-stream。当我运行此文件时，我收到以下错误

C：\ work \ node＆gt;节点测试 events.js：85       扔掉//未处理的'错误'事件             ^ 错误：ENOENT，打开'C：\ work \ node \ work ode est.txt'     在错误（本机）

我也试过使用try-catch但是也有同样的错误。谁能看到我犯的错误并指出？感谢。

这是我的代码..

var fs = require("fs"),
    mongo = require("mongodb"),
    Grid = require("gridfs-stream"),
    gridfs,
    writeStream,
    readStream,
    buffer = "";

    mongo.MongoClient.connect("mongodb://localhost:27017/test", function  (err, db) {
   //  "use strict";
    gridfs = Grid(db, mongo);

   // write file
   writeStream = gridfs.createWriteStream({ filename: "test.txt" });
   fs.createReadStream("C:\work\node\test.txt").pipe(writeStream);
  });

现在可以使用更正的文件路径

   var fs = require("fs"),
   mongo = require("mongodb"),
   Grid = require("gridfs-stream"),
   gridfs,
   writeStream,
   readStream,
   buffer = "";

   mongo.MongoClient.connect("mongodb://localhost:27017/test", function   (err, db) {
 //  "use strict";
   gridfs = Grid(db, mongo);

  // write file
  writeStream = gridfs.createWriteStream({ filename: "test.txt" });
  **fs.createReadStream("C:\/work\/node\/test.txt").pipe(writeStream);**
 });
