jquery ajax 请求获取所有响应头信息

<script src="//statics.1024tools.com/libs/jquery/1.11.1/jquery-1.11.1.min.js"></script>

function initResponseHeaders() {
	$.ajax({
		'type': 'head',
		'url': 'https://1024tools.com/header',
		'success': function(data,status,xhr){
			$('#response').text(xhr.getAllResponseHeaders());
		},
		'error': initResponseHeaders
	})
}

效果如下
