Electron下使用samba相关问题记录

概述

笔者准备在Electron框架下使用samba-client进行远程交互，结果发觉存在基本的使用问题，连基本的连接都有问题：samba-client 代码地址。

猜测可能与samba-server端使用版本有关。（难道samba-client不支持samba2？貌似没看到代码文档说明。）

smb2 （bchelli/mode-smb2）

bchelli/mode-smb2 Github地址
该库较为久远，所支持也很有限，尤其是其支持的uri地址，都比较像Windows专用，果然在测试了某些基本接口后发现如下类似问题：
smb2 read P3 err = Error: STATUS_ACCESS_DENIED (0xC0000022) : {Access Denied} A process has requested access to an object but has not been granted those access rights.

在github上找到了对应issue：https://github.com/bchelli/node-smb2/issues/17

This issue seems to be fixed here:
https://github.com/Node-SMB/marsaud-smb2 at least it worked with
“readdir” for me. For reference: Node-SMB#18 The docs show var SMB2 =
require(‘smb2’); but I had to use var SMB2 = require(‘@marsaud/smb2’);
to reference the package.

@marsaud/smb2 (Node-SMB/marsaud-smb2)

Node-SMB/marsaud-smb2 Github地址
该库从 bchelli/mode-smb2 Github地址 fork而来，作者近期还在维护，可靠度还是蛮高的。

使用如下指令安装即可：

npm install -g @marsaud/smb2@latest

简单测试了下对应的读取文件、下载文件、上传文件、创建目录等基本功能，还是比较靠谱的。唯独在测试上传文件（createWriteStream）时，总是会出现如下报错：

smb2 createWriteStream err = Error: STATUS_ACCESS_DENIED (0xC0000022): {Access Denied} A process has requested access to an object but has not been granted those access rights.

检查后发现，服务器中已经存在对应文件时，则会出现上述问题。经测试，该库基本功能完善，而且还提供了一些更灵活的功能：

smb2Client.open('path\\to\\the\\file', function(err, fd) {if (err) throw err;smb2Client.read(Buffer.alloc(10), // buffer where to store the data0, // offset in the buffer10, // number of bytes to read0, // offset in the filefunction(err, bytesRead, buffer) {smb2Client.close(fd, function() {});if (err) throw cb(err);console.log(bytesRead, buffer);});
});
This API is modeled after Node's fs module.Note: be careful of autoCloseTimeout with this process as it is not intended to cover multiple method calls, you should set it to 0 and manually disconnect().

可以根据实际需求自行扩展。
