php ssh2返回json数据

Question

我在ssh2中遇到了返回数据的问题，当我在终端ssh中执行命令时，结果返回如下

[
    {
            "mac": "xx:xx:xx:xx:xx",
            "name": "test",
            "distance": 630,
            "txpower": 13,
            "noisefloor": -96,
            "airmax": {
                    "priority": 3,
                    "quality": 0,
                    "beam": 255,
                    "signal": -96,
                    "capacity": 0
            },
            "stats": {
                    "rx_data": 5973340,
                    "rx_bytes": 8021746863,
                    "rx_pps": 36,
                    "tx_data": 3666039,
                    "tx_bytes": 690527643,
                    "tx_pps": 26
            },
            "rates": [ "MCS0", "MCS1", "MCS2", "MCS3", "MCS4", "MCS5", "MCS6", "MCS7", "MCS8", "MCS9", "MCS10", "MCS11", "MCS12", "MCS13", "MCS14", "MCS15" ],
            "signals": [ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, -67, -66, -65, 0 ],
            "remote": {
                    "uptime": 3451971,
                    "hostname": "test",
                    "platform": "Rocket",
                    "version": "1",
                    "distance": 1050
            }
    }

]

当我在php中使用ssh2执行相同的命令时，我得到的响应如下

我使用的php代码

            if(($stream=ssh2_exec($conn,$command))) 
            {
                stream_set_blocking($stream, true);
                $stream_out = ssh2_fetch_stream($stream, SSH2_STREAM_STDIO);
                return stream_get_contents($stream_out);
            }

我需要使用php ssh2执行命令并返回类似终端ssh的数据。

Answer 1

只需使用json_encode()方法从json对象中获取json字符串

    if(($stream=ssh2_exec($conn,$command)))
    {
        stream_set_blocking($stream, true);
        $stream_out = ssh2_fetch_stream($stream, SSH2_STREAM_STDIO);
        $streamString = stream_get_contents($stream_out);
        $Result = json_encode($streamString);
        return $Result;
    }

Answer 2

Amersand in shell的意思是在后台运行。您可以看到所有这些后台命令的输出。
