axios post request to send form data

Question

axios POST request is hitting the url on the controller but setting null values to my POJO class, when I go through developer tools in chrome, the payload contains data. What am I doing wrong?

Axios POST Request:

var body = {
    userName: 'Fred',
    userEmail: '[email protected]'
}

axios({
    method: 'post',
    url: '/addUser',
    data: body
})
.then(function (response) {
    console.log(response);
})
.catch(function (error) {
    console.log(error);
});

Browser Response:

If I set headers as:

headers:{
  Content-Type:'multipart/form-data'
}

The request throws the error

Error in posting multipart/form-data. Content-Type header is missing boundary

If I make the same request in postman it's working fine and sets values to my POJO class.

Can anyone explain how to set boundary or how can I send form data using axios.

Answer 1

You can post axios data by using [FormData()][1] like :

var bodyFormData = new FormData();

And then add the fields to the form you want to send :

bodyFormData.append('userName', 'Fred');

If you are uploading images, you may want to use .append

bodyFormData.append('image', imageFile); 

And then you can use axios post method (You can amend it accordingly)

axios({
    method: 'post',
    url: 'myurl',
    data: bodyFormData,
    headers: {'Content-Type': 'multipart/form-data' }
    })
    .then(function (response) {
        //handle success
        console.log(response);
    })
    .catch(function (response) {
        //handle error
        console.log(response);
    });
