$http service returns a promise which has two callback methods as shown below. $http({method: ‘GET’, url: ‘/someUrl’}). success(function(data, status, headers, config) { var anchor = angular.element(‘<a/>’); anchor.attr({ href: ‘data:attachment/csv;charset=utf-8,’ + encodeURI(data), target: ‘_blank’, download: ‘filename.csv’ })[0].click(); }). error(function(data, status, headers, config) { // handle error });
Normal (GET) requests do not have a Content-Type header. For POST requests it would appear as $_SERVER[“CONTENT_TYPE”], with a value like multipart/form-data or application/x-www-form-urlencoded. This is mandated by the CGI/1.1 specification: http://www.ietf.org/rfc/rfc3875.
As explained by Alex’s link you’re probably missing the header Content-Disposition on top of Content-Type. So something like this: Content-Disposition: attachment; filename=”MyFileName.ext”

the default encoding of a HTTP POST is ISO-8859-1. else you have to look at the Content-Type header that will then look like Content-Type: application/x-www-form-urlencoded ; charset=UTF-8 You can maybe declare your form with <form enctype=”application/x-www-form-urlencoded;charset=UTF-8″> or <form accept-charset=”UTF-8″> to force the encoding.

Using BSD sockets or, if you’re somewhat limited, say you have some RTOS, some simpler TCP stack, like lwIP, you can form the GET/POST request. There are a number of open-source implementations. See the “happyhttp” as a sample ( http://scumways.com/happyhttp/happyhttp.html ). I know, it is C++, not C, but the only thing that is “C++-dependant” … Read more
Just set CURLOPT_HEADER to false.
