如何处理错误nodejs JavaScript catch

Question

var result;

    async function verify() {
      const ticket = await client.verifyIdToken({
      idToken: token,
      audience: CLIENT_ID,  
    });
    }

     verify().catch(console.error);

If there is an error, I want to set

var result = 'fail';

if there is no error, I want to set:

var result = 'success'; 

How do I do this?

Why not making your verify to return such result value? Then inside of it you can wrap your client function with try-catch:

async function verify() {
    try {
        const ticket = await client.verifyIdToken(...);
        return 'success';
    } catch(err) {
        // probably some extra logging here
        return 'fail';
    }
}

...

var result = await verify(); // will be either success or fail
