How to transfer parameters when initiating multiple requests with post method in axios.all?

[question 1]: excuse me, how can I use axios.all to initiate multiple requests with post method to transmit parameters? Baidu has seen a lot, all using the get method.
[Question2]: what if I need to wait for the post1 request to succeed before requesting post2,axios to meet my needs? If I am not satisfied, how can I achieve it?
(usage scenario: query user information after successful registration)

1. First of all, if you have requirements for order, you should not put both requests in all, but should put the second request in the first then
2. You can also use async+await to make Synchronize asynchronous and then write

sequentially.
