How to post query parameters with Axios?

I am trying to post on an API with some query params. This is working on PostMan / Insomnia when I am trying to by passing mail and firstname as query parameters :

 http://localhost:8000/api/mails/users/sendVerificationMail?mail=lol%40lol.com&firstname=myFirstName

However, when I am trying to do it with my react native app, I got a 400 error (Invalid Query Parameters).

This is the post method :

.post(`/mails/users/sendVerificationMail`, {
  mail,
  firstname
})
.then(response => response.status)
.catch(err => console.warn(err));

(my mail and firstname are console.logged as follow: [e-mail] and myFirstName).

So I don’t know how to pass Query Parameters with Axios in my request (because right now, it’s passing data: { mail: "[e-mail]", firstname: "myFirstName" }.

Answer

axios signature for post is axios.post(url[, data[, config]]). So you want to send params object within the third argument:

.post(`/mails/users/sendVerificationMail`, null, { params: {
  mail,
  firstname
}})
.then(response => response.status)
.catch(err => console.warn(err));

This will POST an empty body with the two query params:

POST http://localhost:8000/api/mails/users/sendVerificationMail?mail=lol%40lol.com&firstname=myFirstName
