如何使用axios使用async / await将返回值保存到变量中？

Question

所以我有以下示例：

const userApi = async () => {
 const res = await axios({
    url: URL + 'getUserData',
    method: 'post', 
    data: {message: 'getUserList'}
})
 return res.data
};





some_other_function = () => {
const userList = []
userList = userApi().then(res => {
  // console.log(res) works here but i need to get the response data outside...
   return res
 })
console.log(userList) // It's still a promise... Why?

我无法将响应对象放入变量，无论如何，promise都无法解析。我应该怎么做？

userApi().then(res => {
    userList = res //also doesn't work
    return res

}）

console.log(userList)

您正在尝试从函数外部的函数范围内访问变量。试试这个，让我知道它是否有效。

const userApi = async () => {
 const res = await axios({
    url: URL + 'getUserData',
    method: 'post', 
    data: {message: 'getUserList'}
})
 return res.data
};

let userList = []; 
some_other_function = () => {
userList = userApi().then(res => {
  // console.log(res) works here but i need to get the response data outside...
   return res
 })
 
console.log(userList) // It's still a promise... Why?
