**引入proj4脚本文件**

##### 这里加载的坐标是EPSG:4527的Mapserver的地图服务代码如下 #####

<div id="viewDiv"></div>
    <script>
        proj4.defs('EPSG:4527', '+proj=tmerc +lat_0=0 +lon_0=117 +k=1 +x_0=39500000 +y_0=0 +ellps=GRS80 +units=m +no_defs');
        var proj4527 = ol.proj.get('EPSG:4527');
        proj4527.setExtent([506665.4500395897,305104.5729758957,507945.7690395897,306991.48897589574]);
        var view=new ol.View({ 
            projection: 'EPSG:4527',
            center: [506865, 305504],
            zoom: 4
        });
        // 这里放置Mapserver服务链接，我用的是本地的链接
        var url = 'https://localhost:6443/arcgis/rest/services/testcgcs2000/testcgcs2000/MapServer';
        var layers2 = [
            new ol.layer.Image({ 
                source: new ol.source.ImageArcGISRest({ 
                    ratio: 1,
                    params: { },
                    url: url,
                    projection: 'EPSG:4527'
                })
            })
        ];
        var map = new ol.Map({ 
            layers:layers2,
            target: 'viewDiv',
            controls: ol.control.defaults({ "attribution": false}).extend([new ol.control.FullScreen(),new ol.control.OverviewMap()]),
            view: view
        });

当时运行时图不显示，没有报错，后来换了一个服务就好了。  
这里也相当于实现openlayers的坐标系转换了，下面是其他坐标系的EPSG proj4格式。
