JavaScript Client

Here is a sample JavaScript client:

const username = 'admin'
const password = 'wexflow2018'
const workflowId = 1

async function sha256(input) {
  const encoder = new TextEncoder()
  const data = encoder.encode(input)
  const hashBuffer = await crypto.subtle.digest('SHA-256', data)
  const hashArray = Array.from(new Uint8Array(hashBuffer))
  const hashHex = hashArray.map(b => b.toString(16).padStart(2, '0')).join('')
  return hashHex
}

async function getAuthHeader(user, pass) {
  const hashedPassword = await sha256(pass)
  return `Basic ${btoa(`${user}:${hashedPassword}`)}`
}

try {
  const autHeader = await getAuthHeader(username, password)
  const res = await fetch(`https://localhost:8000/api/v1/start?w=${workflowId}`, {
    method: 'POST',
    headers: { 'Authorization': autHeader }
  })
  if (!res.ok) {
    throw new Error(`HTTP ${res.status} - ${res.statusText}`)
  }
  const jobId = await res.json()
  console.log(`Workflow ${workflowId} started successfully. Job ID:`, jobId)
} catch (err) {
  console.error(`Failed to start workflow ${workflowId}:`, err)
}
