使用一系列链接制作多个 Axios 获取请求？

Question

我有一个函数，我想为学生返回所有即将完成的作业。我首先运行另一个异步函数，该函数返回学生在一个学期和一年内的所有课程 ID。然后我用每个类的 .get url 填充一个数组。

我的问题是理解和使用Axios.all()，因为我想对每个班级进行多次调用，然后对每个作业进行排序，只保存迟于学生当前日期的作业。我面临的问题是axios.all([urls]) 返回UnhandledPromiseRejectionWarning: Error: Request failed with status code 401。我不知道为什么我不能从每个 url 调用中返回正确的数据。我把它缩小到我如何设置我的 axios.all 调用的问题。有人能指出我正确的方向吗？

//Get all upcoming assignments from each class for a user
async function getAssignments(){
    //Make multiple requests to api
    axios
        .all([urls])
        //Loop through each assignment for each class
        .then(
            axios.spread((...res) =>{
                for (var i = 0; i < res.data.length; i++) {
                    //If the due date of the assignment is due later than the users current date, push to array
                    if (res.data[i]['due_at'] > date.toISOString()) {
                        assignments.push(res.data[i])
                    }
                }
                //Output all assignments
                return assignments
            })
        )
}

更新： 我忘记将令牌传递给我的标头，经过更多调整后，它现在将从我的数组中获取指定的 url。但我现在需要它来抓取数组中的每个 url 并同时进行调用。虽然我有点难过，但我是否只需要为.get 或更具体的东西创建一个 for 循环？有人能指出我正确的方向吗？

//urls is the array filled with links. Need for the axios calls to happen concurrently
axios.all([axios.get(
    urls[0],
    {
        headers: {
            Authorization: `Bearer ${token}`,
        },
    }
)])
//Loop through each assignment in a specfied class in canvas
.then(
    axios.spread((...res) =>{
        for (var i = 0; i < res[0].data.length; i++) {
            //If the due date of the assignment is due later than the users current date, push to array
            if (res[0].data[i]['due_at'] > date.toISOString()) {
                assignments.push(res[0].data[i])
            }
        }
        console.log(assignments)
    })
)
.catch((err) => console.log(err))

假设你已经创建了你的 axios 实例，你可以在最初在 axios 实例级别设置标题，你可以简单地，

const axios = require('axios');
axios.defaults.headers.common['Authorization'] = 'Bearer AUTH_TOKEN';

//Get the course ID for each class the user is assigned to
    const courseID = await getCurrentCourses('Spring', '2021')
    //Fill the array with urls to each course assignment page
    for(let i = 0; i < courseID.length; i++){
        urls.push(axios.get('https://example.com/api/v1/courses/' + allCourseID[i] + '/assignments'));
    }
     //Make multiple requests to api
        axios.all(urls)
            //Loop through each assignment for each class
            .then({......});
