C# 调用ArcGIS server admin api

一、AGS server admin api 介绍

1.1什么是admin api

AGS Server Admin api 官方的称呼是 AGS Server administrator api, 通过这名字也可以猜出该api的作用，通过该api可以管理arcgis server。ArcGIS Server常见的管理功能有安装配置、server 日志、站点的监测配置等，详细的Server管理内容，可以参考ArcGIS Server的官方帮助的管理arcgis Server。

1.2 admin api 作用

通常ArcGIS Server的管理是通过在manager页面中进行的。但是arcgis server manager所呈现的管理功能其后台也是通过调用admin api。也就是说manager页面的管理是esri通过调用admin api开发出来的web 端的server管理工具。有些server的管理工具在manager找不到，但是可以从admin中页面中获得。

通过调研admin api 完全可以开发一个管理工具来替代manager，从中根据自己的业务需求定制所需要的功能。一句话概括就是使用admin api可以二次开发出server管理系统。目前使用admin api开发比较好的产品为，捷泰天域开发的oneMap，其就是一个通过调用admin api开发出的server管理工具，通过oneMap可以方便的实现manger 已有的功能，也可以实现诸如日志统计分析、管理数据的统计，并将统计信息已图表的形式呈现这种manger没有呈现的功能。

如果用户不想基于admin api 开发新的server管理系统，而想对ArcGIS server manager中的内容进行更改，可以直接进行admin页面中，链接格式如下：http://localhost:6080/arcgis/admin/login，可以在这里面对manager进行管理。

Tips: 10.2 server的admin 中添加了站点的备份与恢复

1.3 admin api的实质

admin api 的实质也就是rest api，通过发送参数为json格式的http请求，实现操作。则可以看出，只要任何可以发送http请求的编程语言都可以用来调用admin api，像java，python，c# 等，本文就采用C# 调用Admin api进行示例。

二、使用C#调用admin api

admin api 通常调用遵循以下步骤：

1.获取token

根据站点用户名和密码生成token和证书

  private string GenerateAGSToken()
        {
            try
            {
                string urlGenerateToken = string.Format("{0}/generateToken", this.urlRestAdmin);
                string credential = string.Format("username={0}&password={1}&client=requestip&expiration=&f=json", this.username, this.password);
                string result = this.GetResult(urlGenerateToken, credential);

                JsonObject jsonObject = new JsonObject(result);
                string token = null;
                if (!jsonObject.Exists("token") || !jsonObject.TryGetString("token", out token))
                {
                    throw new Exception("Token not found!");
                }

                return token;
            }
            catch(Exception ex)
            {
                return string.Empty;
            }
        }

2.构建json格式的参数

根据执行的操作所需要的参数，构建json格式的参数，这里以创建服务操作作为例子，进行json字符串的构建。这里使用的JsonObject对象为SOE开发中的链接库ESRI.ArcGIS.SOESupport.dll 所带。

  public bool CreateService()
        {
            try
            {
                string token = this.GenerateAGSToken();
                string serviceUrl = this.urlRestAdmin + "/services/createService";

                JsonObject jsonObject = new JsonObject();
                jsonObject.AddString("serviceName", "Test");
                //服务类型
                jsonObject.AddString("type", Enum.GetName(typeof(ServiceType), ServiceType.GPServer));
                jsonObject.AddString("description", "This is an example");
                //不同的服务类型，其capabilities是不同的，地图服务的为Map，query和data
              //  jsonObject.AddString("capabilities", "Map,Query,Data");

                jsonObject.AddString("capabilities","Uploads");//gp 服务的capabilities
                jsonObject.AddString("clusterName", "default");
                jsonObject.AddLong("minInstancesPerNode", 1);
                jsonObject.AddLong("maxInstancesPerNode", 2);
                jsonObject.AddLong("maxWaitTime", 60);
                jsonObject.AddLong("maxStartupTime", 300);
                jsonObject.AddLong("maxIdleTime", 1800);
                jsonObject.AddLong("maxUsageTime", 600);
                jsonObject.AddLong("recycleInterval", 24);
                jsonObject.AddString("loadBalancing", Enum.GetName(typeof(LoadBalancing), LoadBalancing.ROUND_ROBIN));
                jsonObject.AddString("isolationLevel", Enum.GetName(typeof(IsolationLevel), IsolationLevel.HIGH));

                JsonObject jsonObjectProperties = new JsonObject();

                // see for a list complete http://resources.arcgis.com/en/help/server-admin-api/serviceTypes.html
                jsonObjectProperties.AddLong("maxBufferCount", 100); // optional 100
                jsonObjectProperties.AddString("virtualCacheDir", this.urlRestServer + "/arcgiscache"); // optional
                jsonObjectProperties.AddLong("maxImageHeight", 2048); // optional 2048
                jsonObjectProperties.AddLong("maxRecordCount", 1000); // optional 500

               //10.1中服务是通过msd的形式发布的，所以创建地图服务时候将mxd转换成msd的形式，创建msd的形式而其他服务的数据发布形式，参考上面的链接
               
              //  jsonObjectProperties.AddString("filePath", @"C:\AvGis\Test\mappa\UTM_ReteFognaria.msd"); //地图服务 required
                        
               
                jsonObjectProperties.AddString( "toolbox",@"d:\Buffer.tbx");//gp服务使用的是路径创建gp服务的路径

                jsonObjectProperties.AddLong("maxImageWidth", 2048); // optional 2048
                jsonObjectProperties.AddBoolean("cacheOnDemand", false); // optional false
                jsonObjectProperties.AddString("virtualOutputDir", this.urlRestServer + "/arcgisoutput");
                jsonObjectProperties.AddString("outputDir", @"C:\arcgisserver\directories\arcgisoutput");
                jsonObjectProperties.AddString("jobsDirectory", @"C:\arcgisserver\directories\arcgisjobs");                                                                             // required
                jsonObjectProperties.AddString("supportedImageReturnTypes", "MIME+URL"); // optional MIME+URL
                jsonObjectProperties.AddBoolean("isCached", false); // optional false
                jsonObjectProperties.AddBoolean("ignoreCache", false); // optional false 
                jsonObjectProperties.AddBoolean("clientCachingAllowed", false); // optional true 
                jsonObjectProperties.AddString("cacheDir", @"C:\arcgisserver\directories\arcgiscache"); // optional

                jsonObject.AddJsonObject("properties", jsonObjectProperties);

                string result = this.GetResult(serviceUrl, "service=" +HttpUtility.UrlEncode(jsonObject.ToJson()) + "&f=json&token=" + token);
                return this.HasSuccess(result);
               
            }
            catch
            {
                return false;
            }
        }

admin api中的各项参数，详见admin api的帮助：http://resources.arcgis.com/en/help/server-admin-api/，参数分为required和optional。

3.发送http请求

admin api可以支持两者get和post请求。server管理功能中有些操作是不支持get请求的。

get请求

  private string GetResult(string url)
        {
            try
            {
                WebRequest request = WebRequest.Create(url);
                WebResponse response = request.GetResponse();
                using (Stream responseStream = response.GetResponseStream())
                {
                    using (StreamReader reader = new StreamReader(responseStream))
                    {
                        return reader.ReadToEnd();
                    }
                }
            }
            catch
            {
                throw;
            }
        }

post请求

rivate string GetResult(string url, string postContent)
        {
            try
            {
                WebRequest request = WebRequest.Create(url);
                byte[] content = Encoding.UTF8.GetBytes(postContent);
                request.ContentLength = content.Length;
                request.ContentType = "application/x-www-form-urlencoded";
                request.Method = WebRequestMethods.Http.Post;
                using (Stream requestStream = request.GetRequestStream())
                {
                    requestStream.Write(content, 0, content.Length);
                    requestStream.Close();
                    WebResponse response = request.GetResponse();
                    using (Stream responseStream = response.GetResponseStream())
                    {
                        using (StreamReader reader = new StreamReader(responseStream))
                        {
                            return reader.ReadToEnd();
                        }
                    }
                }
            }
            catch
            {
                throw;
            }
        }
