使用.Net操作 Geoserver REST API的shpfile发布

因为Geoserver REST支持Http的GET/PUT/POST请求，所以可以在C#中可以通过创建Http请求来达到操作Geoserver的目的。下面是代码：

        private static readonly string contentType = "text/xml";
        private static readonly string userName = "admin";        //geoserver账号
        private static readonly string password = "geoserver";      //geoserver密码
        private static readonly string geoserver = "http://localhost:8080/geoserver";      //geoserver的url

        private static void Create() 
        {
            string workspaceName = "TestWorkSpace";    //添加数据的工作区
            string storeName = "TestPoint";            //添加的数据显示名称
            string filePath = @"D:\TestFile\TestPoint.shp";         //需要添加的数据源
            string str = CreateWorkSpace(workspaceName);         //创建工作区
            str = CreateStore(workspaceName, filePath, storeName);       //在存在的工作区创建数据源
            str = PublishStore(workspaceName, storeName, null);
        }

        /// <summary>
        /// 创建geoserver新工作区
        /// </summary>
        /// <param name="workspaceName"></param>
        /// <returns></returns>
        private static string CreateWorkSpace(string workspaceName)
        {
            string url = geoserver + "/rest/workspaces";
            string xmlString = "<workspace><name>" + workspaceName + "</name></workspace>";
            string str = "";
            try
            {
                str = CreatePost(url, xmlString, Encoding.UTF8);
                if (str == workspaceName)
                    return "工作区创建成功";
                else
                    return "工作区创建成功";
            }
            catch (Exception ex)
            {

            }
        }
