Question

我是nodejs的新手，我想同步执行多个axios请求。可能吗？在下面的示例中，我在data变量中有3个对象，我想执行第一个请求，只有在收到确认第一个请求已完成的确认后，再执行第二个请求，然后才收到第二个请求的确认请求完成并执行第三个请求，依此类推。我可以在nodejs中做类似的事情吗？还是有更好的方法做到这一点？有人可以帮我显示一些代码示例吗？

谢谢瓦格纳

const resourceInfo = [
    { resource: "resource1"  , route: "http://localhost:3001/api/route1" },
    { resource: "resource2"  , route: "http://localhost:3002/api/route2" },
    { resource: "resource3"  , route: "http://localhost:3003/api/route3" },
    { resource: "resource4"  , route: "http://localhost:3004/api/route4" },
    { resource: "resource5"  , route: "http://localhost:3005/api/route5" }
]

function getEndpoint(resource) {
    const info = resourceInfo.filter(e => {
        if (e.resource === resource) return e.route
    })
    return info[0]
}

async function doSomeRequests(body) {

    const { resourceList } = body
    for (element of resourceList) {
        const endpoint = getEndpoint(element.resource['route']
        const headers = config.get('headers')
        const options = {}
        options['id'] = element.id
        options['val1'] = element.val1
        options['val2'] = element.val2
        options['val3'] = element.val3
        options['val4'] = element.val4
        options['val5'] = element.val5

        try {
            const result = await axios.post(endpoint, options, headers)
            io.emit('statusReport', result.data)
        } catch (error) {
            debug(`Something went wrong: ${error}`)
        }
    }
}

const data = {
    resourceList: [
        {id: 355, val1: 1, val2: 2, val3: 3, val4: 4, val5: 5},
        {id: 484, val1: 10, val2: 20, val3: 30, val4: 40, val5: 50},
        {id: 633, val1: 100, val2: 200, val3: 300, val4: 400, val5: 500}
    ]
}
await doSomeRequests(data)
