使用 Async Await 处理错误和异常

Question

我目前正在编写一些 promise 繁重的脚本，并且我正在尝试确定捕获和管理响应和错误的最佳方法。 我的很多代码都需要解决和确认以前的代码。 由于响应失败可能是 object 说它失败的原因，我需要进行比较以查看 X 是否在实际响应中，因此我要求在 promise 解决后继续前进的最佳方法。 我在下面有三个我的书面场景

/* 
    First potential method?
    Smart supporting function??
*/
// Error catching in the supporting function??
async function runfakeFunction() {
    try {
    var output = await fakeFunction({}).promise()
    return await output
    } catch(err) {
        console.error(err)
    }
}
// Call the above function and store it?
var response = await runfakeFunction()

// Ensure the output I returned is as expected?
if(response !== undefined){
    console.log('success')
} else {
    console.log('errored')
}

/* 
    Second potential method?
    Dumb supporting function??
    Follow up question is would I just nest my supporting functions in the .then() block or would I store the response and use a seperate function??
*/
async function runfakeFunction() {
    return await fakeFunction({}).promise() // for this dumb function .promise() is required
}

runfakeFunction().then((response) => {
    // run next dependant code here?
}).catch((err) => {
    // run failure code here?
})

/* 
    Third potential method?
    Try and Catch block around the base SDK function
*/
try{
    var testing = await fakeFunction({}).promise() // for this dumb function .promise() is required
} catch (e) {

}
// Ensure the output I returned is as expected?
if(testing !== undefined){
    console.log('success')
} else {
    console.log('errored')
}
