怎么让图片在一个正方形div中不变形展示？且超出部分截取（隐藏），且截取图片的中间位置

.divContent{
	width:200px;
	height: 200px;
	border:1px solid red;
	overflow:hidden;
}
.divContent img{
	margin:0;
	padding:0;
	width:100%;
	height: 100%;
	object-fit: cover;//重要
}
.yuanImg{
	width:200px;
	height: auto;
}

<p>图片一：长大于宽</p>
<div class="divContent">
	<img src="http://img4.imgtn.bdimg.com/it/u=3357021395,3491635869&fm=27&gp=0.jpg">
</div>
<p>图片二：长小于宽</p>
<div class="divContent">
	<img src="http://img2.imgtn.bdimg.com/it/u=888348881,1176056835&fm=27&gp=0.jpg">
</div>
