[nodeJS][python-shell]如何使用python-shell发送图片？（nodejs到python）

Question

I'm working on a project and I need to send image(frame) in realtime. Server is NodeJs, and I will process this image using OpenCV in python-shell But I don't know how to send Image through python shell, to python code.. can you tell me how to send image from nodejs to python?

var PythonShell = require('python-shell');


var options = {
    mode: 'text',
    pythonOptions:['-u'],
    scriptPath:'C:/Users/multi/'
};


PythonShell.PythonShell.run("pycudacode.py",options,function(err){
    if(err) console.log('err msg:', err);
    console.log('finishied');
}
)

this is my code. thank you.

Answer 1

global.pyshell = require('python-shell');
var fs = require("fs");


var data = fs.readFileSync("testimg.jpg"); // I will get video frame from the client.
var base64 = data.toString("base64");

var options = {
    mode: 'text',
    pythonOptions:['-u'],
    scriptPath:'C:/Users/multi/'
};



shell = new pyshell.PythonShell("sendex.py",options,function(err){
    if(err) console.log('err msg:', err);
    console.log('finishied');
}
)

shell.send(base64);

shell.on("message", rebase64 => {
    var err = null;
    result = Buffer.from(rebase64, "base64");
    console.log(result);
    console.timeEnd("time")
    fs.writeFileSync("result.jpeg",result);
});
shell.end(err=>{
    if(err){
        console.log(err);
    }
});

I solved it and it is my code.
