Upload csv file in Reatjs frontend and send it back to backend server

Question

我想在 Reatjs 前端上传 csv 文件并将其发送回后端服务器（Spring Rest API）。

Answer 1

NPM has lot of things that solve this issue. Checkout react-upload-file

Answer 2

you could simply make a post http request with the file appended in a form data object, like this using axios (or any other lib you prefer)

 const formData = new FormData();
 formData.append("file", yourStateFile);
 axios.post('yourUrl', formData, {
   headers: {
     'Content-Type': 'multipart/form-data'
   }
})
