How spawn curl request in function beforeRender ?

Romeiros

Hi, how i can do spawn curl request from cmd.exe in function beforeRender ?
For example

  const { spawn } = require('child_process');

   let args = [
       ...some args
    ];

    const curl = spawn('curl',
        args, {
            shell: true
        }
    );

   curl.on('close', (code) => {
        console.log(`child process exited with code ${code}`);
    });

    curl.on('data', (data) => {
        console.log(data)
    });

Thank you in advance

Isn't it better to use a nodejs module for making http requests? Like this

//load some data from the remote API
function beforeRender(req, res, done) {
    require('request')({
      url:"http://service.url",
      json:true
    }, function(err, res, body){
        req.data = Object.assign({}, req.data, body);
        done();
    });
}

i use curl, because i need do request to service, where use kerberos authentication. And i think its possible to do only if use curl with flag --negotiate. Thank you.

Maybe I am wrong but I doubt it won't with a module.

However here is the code for curl you can expand

const spawn  = require('child_process').spawn

function beforeRender(req, res, done) {
    const curl = spawn('curl', ['https://jsreport.net'], { shell: true })    

    curl.stdout.on('data', (data) => {
        console.log(`stdout: ${data}`)
    })

    curl.stderr.on('data', (data) => {
        console.error(`stderr: ${data}`)
    })

    curl.on('close', (code) => {       
        done()
    })
}
