尝试使用Angular $ http通过表单异步提交文件

Question

I am trying to submit a file asynchronously via Angular. This is the HTML:

<form ng-submit="videoSubmit()">
    <input id="upl-0"  type="file" name="upl" accept="video/ogg, video/mp4, video/webm">
    <input type="submit" value='Submit' />
</form>

My Angular code:

 $scope.videoSubmit = function() {

    var file = document.getElementById('upl-0').files[0];

    var formData = new FormData();
    console.log(file);
    formData.append("upl", file, file.name);
    console.log(formData);
    console.log(formData.getAll("upl"));

    $http({
            method: 'POST',
            url: "api/asset/upload-test",
            data: formData,
            headers: {
                'Content-Type': 'multipart/form-data'
            }
        })
        .then(function(result) {
            console.log(result);
        });
 };

This definitely attaches the file to the formData object because it is displaying the right file data in the console.

Now I want to do something with this on the server, but in the meantime I just want to actually get this working, so this is all that's on the server:

 router.post('/api/asset/upload-test', function(req, res) {
    console.log(req.data);
    console.log(req.body);
 });

However somehow the server just doesn't receive the file, and displays undefined for req.data and {} for req.body. Why is this and how can I get this actually working in the same implementation, so without having to encode or decode the file in something like base64 or similar. Thanks.

Answer 1

should be in req.files and in order for that you'll need to use express.bodyParser(). If you use express of course.
