使用
GeoHelper geoHelper = new GeoHelper();

下面是介绍，都是从上面代码分段提取出的，可以选择使用
一、创建工作区
HttpGeoServerRest _http = new HttpGeoServerRest();
private static string _server = Config.GetValue("GeoServerUrl");//http://localhost:8080/geoserver
/// <summary>
/// 判断是否存在工作区
/// </summary>
/// <param name="workspaceName"></param>
/// <returns></returns>
public bool WorkSpaceExist(string workSpaceName)
{
try
{
string url = _server + "rest/workspaces/" + workSpaceName + ".json";
//检查Store
String workspace = _http.CreateGet(url);
if (workspace.IndexOf("No such workspace") > -1)
{
return false;
}
return true;
}
catch (Exception ex)
{
return false;
}
}
/// <summary>
/// 查看工作区是否存在，不存在则添加
/// </summary>
/// <param name="workSpaceName"></param>
/// <returns></returns>
public bool WorkSpeceNoExistThenAdd(string workSpaceName) {
if (WorkSpaceExist(workSpaceName)) {
return true;
}
return AddWorkSpace(workSpaceName);
}
/// <summary>
/// 添加工作区
/// </summary>
/// <param name="workSpaceName"></param>
/// <returns></returns>
public bool AddWorkSpace(string workSpaceName) {
try
{
string url = _server + "rest/workspaces";
PostWorkSpaces workSpaces = new PostWorkSpaces();
workSpaces.workspace = new PostWorkSpaces.WorkSpaceObj() { name = workSpaceName };
string json = Newtonsoft.Json.JsonConvert.SerializeObject(workSpaces);
String newWorkSpaceName = _http.CreatePost(url, json, "text/json");
if (newWorkSpaceName.Equals(workSpaceName))
{
return true;
}
return false;
}
catch (Exception ex)
{
return false;
}
}
private class PostWorkSpaces {
public WorkSpaceObj workspace { get; set; }
public class WorkSpaceObj
{
public string name { get; set; }
}
}
二、上传数据存储
public bool AddCoverageStores(string workSpacesName,string coverageStoresName,string url, string type= "GeoTIFF", string enabled= "true") {
if (!WorkSpeceNoExistThenAdd(workSpacesName)) {
throw new Exception("添加工作区失败");
}

{
name=coverageStoresName,
url= "file://"+url,
workspace=new PostCoverageStores.WorkspaceObj() {
name=workSpacesName,
link="string"
}
};
string rqjson = Newtonsoft.Json.JsonConvert.SerializeObject(coverageStores);
String newCoverageStoreName = _http.CreatePost(_server + "rest/workspaces/"+workSpacesName+"/coveragestores", rqjson, "text/json");
if (newCoverageStoreName.Equals(coverageStoresName)) {
return true;
}
return false;
}
private class PostCoverageStores {
public CoverageStoreObj coverageStore { get; set; }
public class CoverageStoreObj {
public string name { get; set; }
public string type { get; set; } = "GeoTIFF";
public bool enabled { get; set; } = true;
public string url { get; set; }
public WorkspaceObj workspace { get; set; }
}
public class WorkspaceObj {
public string name { get; set; }
public string link { get; set; }
}
}
三、发布图层
public bool ReleaseCoverages(string workSpacesName, string coverageStoresName, string coverageName, List<string> supportedFormatsStringList=null,string title="",string nativeCRSDollar="", string srs= "EPSG:3395", string nativeFormat= "GeoTIFF")
