sending file and json in POST multipart/form-data request with axios
Try this.
doAjaxPost() {
var formData = new FormData();
var file = document.querySelector('#file');
formData.append("file", file.files[0]);
// formData.append("document", documentJson); instead of this, use the line below.
formData.append("document", JSON.stringify(documentJson));
axios({
method: 'post',
url: 'http://192.168.1.69:8080/api/files',
data: formData,
})
.then(function (response) {
console.log(response);
})
.catch(function (response) {
console.log(response);
});
}
You can decode this stringified JSON in the back-end.
To set a content-type you need to pass a file-like object. You can create one using a Blob
.
const obj = {
hello: "world"
};
const json = JSON.stringify(obj);
const blob = new Blob([json], {
type: 'application/json'
});
const data = new FormData();
data.append("document", blob);
axios({
method: 'post',
url: '/sample',
data: data,
})
