代码：

var test_id = new ObjectID();    
var gridStore = new GridStore(mongoose.connection.db, test_id , 'test_gs_getc_file' , 'w');
    gridStore.open(function(err, gridStore){
        var data = fs.readFileSync('./test.jpg');
        gridStore.write(data, function(err, doc){
            gridStore.close(function(err, doc){
                GridStore.read(mongoose.connection.db, test_id , function(err, data){
                    if(err){
                        console.log("ERROR", err);
                    }else{
                        console.log("FILE data", data);
                    }
                })
            })
        })
    })

该文件正在保存在fs.chunks和fs.files集合中。但是当我尝试读取文件时，它给出了Illegal chunk format错误。

我试过了

  1. writeFile 方法，但它会导致相同的错误
  2. 重新安装了 mongodb，但它导致同样的错误
