axios post请求发送表单数据 [英] axios post request to send form data

问题描述

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: '[e-mail]'
}

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.

解决方案

You can post axios data by using FormData() 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);
  });
