为什么我的 Node SSH 2 身份验证失败？

如何解决为什么我的 Node SSH 2 身份验证失败？

我想建立一个到 HPe Comware 5510 的节点 ssh2 连接。我可以连接到其他设备，但不能连接到这个设备。我知道有不同类型的身份验证，但它们总是失败。

这是我的代码：

const router =  require("express").Router();

var Client = require('ssh2').Client;


router.post("/",(req,res)=>{

    let json = req.body;
    console.log(json)
 
    var conn = new Client();
    conn.on('ready',function() {
        console.log('Client :: ready');
        let count = 0;
        let result = {};
        let cmd = null;
        let block = ""

        conn.shell((err,stream) => {
                if (err) res.json({err:err})
                stream.on('close',() => {
                    console.log('Stream :: close');
                    conn.end();
                res.json(result)
                }).on('data',(data) => {
                data = data.toString();

                    console.log('OUTPUT: ' + data);
                

                if(cmd) {
                    result[count + "- "+ cmd.value] += data;
                }

                if(data.endsWith("# ")) {
                    cmd = json.cmds[count];
                    count++;
                    if (!cmd) return stream.end("exit\n");

                    if (cmd.type == "cmd") stream.write(cmd.value + "\n");
                    if (cmd.type == "block") stream.write(cmd.value + "\n");

                }
                });


        });
        

    }).on('keyboard-interactive',function (name,descr,lang,prompts,finish) {
            var password = json.credentials.password;
            return finish([password]);
    }).on('error',function(err) {
        console.log(err);
        res.json({err:err})
    
    })
    .connect({
        host: json.ip,port: 22,username: json.credentials.username,password: json.credentials.password,tryKeyboard: true
                
    }); 
})

我认为问题在于它从不执行键盘交互代码。

当我尝试连接时出现此错误：

{ Error: All configured authentication methods Failed
    at doNextAuth (/home/ccuartero/node/autocmd/node_modules/ssh2/lib/client.js:413:17)
    at tryNextAuth (/home/ccuartero/node/autocmd/node_modules/ssh2/lib/client.js:484:5)

    at doWrite (_stream_writable.js:415:12) level: 'client-authentication' }

也通过设置调试函数回调我得到这个日志

似乎应该执行键盘交互回调。
