GeoServer REST发布地图服务

GeoServer REST API支持通过REST接口将shapefile、raster的(image)、数据库中的空间表（如sqlserver spatial、oracle、mysql、postgresql等）发布成服务，本文以C#中调用GeoServer REST API发布一个image(PNG)格式的地图数据（上篇文章有如何使用 C#调用Geoserver REST ）

 XmlDocument xmlDoc = new XmlDocument();
                xmlDoc.Load(Application.StartupPath + "\\Layer.xml");
                string xml = xmlDoc.InnerXml;

                string url_coveragestores = ConfigObject.Server + "rest/workspaces/QPE/coveragestores/" + name + "/coverages";
                string contentXml_coveragestores = xml;

                contentXml_coveragestores = contentXml_coveragestores.Replace("{gisos_coverage_name}", name);

               

                var response_coveragestores = "";
                try
                {
                    response_coveragestores = _http.CreatePost(url_coveragestores, contentXml_coveragestores, null);
                }
                catch (Exception ex)
                {
                    response_coveragestores = "错误";
                    writeLog("创建Layer " + name + " 出错" + ex.ToString());
                }
                if (response_coveragestores.Length > 0)
                {
                    writeLog("创建Layer " + name + " 出错");
                    return;
                }

                writeLog("创建Layer成功 " + " " + name);
                Thread.Sleep(2000);

Layer.xml是什么? 您看了GeoServer的REST API就会明白需要这个配置，示例如下：
