Same function signature

Exactly the same async function signature.

function (ctx, data) {}

data: Request body data, parsed as JSON by default

Extensions

• ctx.req: The pass-through Express standard HTTP request object
• ctx.res: The pass-through Express standard HTTP response object
• These two methods are optional for use, even no response made by ctx.res would NOT block the HTTP request handler

Sample Function

Another plain forwarder

// Standard Express style HTTP sync function
export const tryKnative = (req, res) => {
  res.send(`Hello, ${req.query.u || 'World'}!`);
};

// OpenFunction standard function which could 
// set bridge between sync and async function
export const tryKnativeAsync = async (ctx, data) => {
  console.log('Data received: %o', data);

  // Forward HTTP body to Dapr outputs
  await ctx.send(data);

  // Send something back as HTTP response 
  // when necessary
  // ctx.res.send(data);
};

Remember to build the function, either when applying Function CR manifest or directly via Pack CLI tool
