Sending multiple type of content in same request

Question

I'm using angular 1.5 and I have to hit a service to upload a file. In the same service I have to pass a JSON as request body too.

When I'm using Content-type: application/json multipart for file is not working, if I use Content-type: undefined then multipart will work but JSON param wont work. So is there any way like I can set a value of a key-value pair of a json as a multipart? Or any other way to do this?

Thanks

Try it like this way and you will be fine:

$scope.uploadMultipart = function(file, jsonObject, uploadUrl){
    var formData = new FormData();

    formData.append('json',JSON.stringify(jsonObject));
    formData.append('file', file);

    return $http({
        url: uploadUrl,
        method: 'POST',
        data: formData,
        headers: { 'Content-Type': undefined},
        transformRequest: angular.identity
    });
};

I would not recommend it but thats how you could add the file as a part of a JSON object. In that way you be able to post a in content-type application/json.

$scope.uploadHack = function(file, jsonObject, uploadUrl){

    var aReader = new FileReader();
    aReader.readAsText(file, "UTF-8");
    aReader.onload = function (evt) {

        //append file to json as raw data
        jsonObject.file = {
            content:  aReader.result,
            name: file.name,
            size: file.size
        };

        $http({
            url: uploadUrl,
            method: 'POST',
            data: jsonObject,
            headers: { 'Content-Type': 'application/json'},
            transformRequest: angular.identity
        });
    }
};
