vscode插件开发记录---ssh调用的两种实现方式对比

• 方式一---依赖ssh.exe的子进程调用:

import * as child from "child_process";

const childProc = child.spawn(command, args, Object.assign({}, options, { env: currentEnv }));
childProc.stdout.on("data", (data) => {
    data = data.toString();
    result = result.concat(data);
});
childProc.stderr.on("data", (data) => {
});
childProc.on("error", reject);
childProc.on("close", (code) => {
});
//====================================
let ls = child.exec(command, options);
ls.stdout.setEncoding('binary');
ls.stdout.on('data', (data:string) => {
    let dd = iconv.decode(new Buffer(data, 'binary'), 'UTF-8');
...
});
ls.stderr.setEncoding('binary');
ls.stderr.on('data', (data:string) => {
    let dd = iconv.decode(new Buffer(data, 'binary'), 'UTF-8');
...
});
ls.on('error', function (error) {
    reject(error);
    return;
});
ls.on('close', (code) => {
    if (error.length > 0 && code != 0) {
        reject(error + `error code:${code}`);
        return;
    }
    resolve(error);
});

• 方式二---依赖纯ts实现的ssh2实现ssh调用:

ssh2的一些使用参考:https://github.com/cweijan/vscode-ssh
ssh.client?.exec("echo 123",function(err, stream){
    if (err) throw err; 
    stream.on('data', async function(data:any) {
        const tempPath = await FileManager.record(`temp/result.mul`, null, FileModel.WRITE);
        ....
    });
});
ssh.client?.shell(false,function(err,stream){
    if (err) throw err;
    stream.on('data', function(data: string) {
        Console.log('STDOUT: '+ data);
    }).stderr.on('data', function(data) {
        Console.log('STDERR: '+ data);
    });
    stream.write("bash -c '/xxx/install.sh'\n");
    stream.write("bash -c '/xxx/config.sh'\n");
})
