download csv file from web api in angular js

Question

    [HttpPost]
    public HttpResponseMessage GenerateCSV(FieldParameters fieldParams)
    {
                


        

Answer 1

I think the best way to download any file generated by REST call is to use window.location example :

    $http({
        url: url,
        method: 'GET'
    })
    .then(function scb(response) {
        var dataResponse = response.data;
        //if response.data for example is : localhost/export/data.csv
        
        //the following will download the file without changing the current page location
        window.location = 'http://'+ response.data
    }, function(response) {
      showWarningNotification($filter('translate')("global.errorGetDataServer"));
    });
