How to send a file via Axios to Laravel

问题

I need to post a File from client to server via Axios.

Here is my Vuejs code :

methods: {
    'successUpload': function (file) {
        const config = { headers: { 'Content-Type': 'multipart/form-data' } };
        axios.post('/Upload/File',file, config).then(function (response) {
            console.log(response.data);
        });
    }
}

And here is my Laravel code for handling sent file :

public function uploadFile(Request $request)
{
    if($request->hasFile('file'))
      return "It's a File";

    return "No! It's not a File";
}

But it always returns No It's not a File.

Any helps would be great appreciated.

回答1:

You have to create a FormData object and append the image file.

methods: {
  'successUpload': function (file) {

    let data = new FormData();
    data.append('file', document.getElementById('file').files[0]);

    axios.post('/Upload/File',data).then(function (response) {
        console.log(response.data);
    });
  }
}

An example is here.

Let me know if that works.
