AngularJS: upload and post photo as multi-part form data and get response

Question

I want to upload an image and post it to my server which should post the image further on to some API and get its response.

I could probably use view with something like:

<form ng-submit="updatePhoto(myphoto)"> 
    <p>Choose Photo:</p>
    <input type="file" ng-model="myphoto">
    <input type="submit" value="Send">
</form>

and then in the controller the function would have something like:

$http({
        method: 'POST',
        url: 'myAPIserver.php/',
        data: "myPhoto=" + photo,
        headers: {'Content-Type': 'multipart/form-data'}
});

But this is not correct and I am not sure how to accomplish this. The catch is that I am sending this photo to my PHP proxy first and from there I use curl to make direct API requests.

I hope I was clear enough. Any suggestions appreciated, thanks

I managed to accomplish this with the help of custom directive that I got here. You need a custom directive for file upload if you want to access files (ngModel wont work, see this for more info).

Using first link:

<form ng-submit="updateSth()" name="uploadForm" enctype="multipart/form-data">
    <input name="file" type="file" id="file" file-model="fileToUpload" />
    <input name="somethingINeed" type="submit" value="Upload" />
</form> 

you can access the uploaded file with $scope.fileToUpload now, which makes everything easier. I extracted the function from the service given on the first link and didn't use it as a service since it suited me better this way …
