第16章：高级功能与扩展服务

16.1 数据导入服务

ImporterService 提供了批量导入数据的高级功能。

var importerService = factory.CreateImporterService();

// 创建导入任务
var importTask = new ImportTask
{
    TargetWorkspace = "myWorkspace",
    TargetStore = "myDataStore"
};

var taskId = await importerService.CreateImportTaskAsync(importTask);

// 上传文件到导入任务
var zipFile = File.ReadAllBytes("data.zip");
await importerService.UploadFileToTaskAsync(taskId, zipFile);

// 执行导入
await importerService.ExecuteImportAsync(taskId);

16.2 TransformService - 坐标转换

var transformService = factory.CreateTransformService();

// 转换坐标
var result = await transformService.TransformAsync(
    new CoordinateTransformRequest
    {
        SourceCRS = "EPSG:4326",
        TargetCRS = "EPSG:3857",
        Coordinates = new[] { 116.4074, 39.9042 }
    });

Console.WriteLine($"转换后坐标: {result.X}, {result.Y}");

16.3 URLCheckService - URL验证

var urlCheckService = factory.CreateURLCheckService();

// 验证外部URL
var isValid = await urlCheckService.CheckURLAsync("https://example.com/wms");
Console.WriteLine($"URL 有效性: {isValid}");

16.4 KeystoreService - 密钥存储

var keystoreService = factory.CreateKeystoreService();

// 获取密钥库信息
var keystores = await keystoreService.GetKeystoresAsync();

foreach (var keystore in keystores)
{
    Console.WriteLine($"密钥库: {keystore.Name}");
    Console.WriteLine($"类型: {keystore.Type}");
}

16.5 Blobstore Service - Blob存储

var blobstoreService = factory.CreateBlobstoreService();

// 配置S3 Blob存储
var s3Config = new BlobstoreConfig
{
    Name = "s3_storage",
    Type = "S3",
    Configuration = new Dictionary<string, object>
    {
        ["bucket"] = "my-geoserver-bucket",
        ["prefix"] = "tiles/",
        ["region"] = "us-west-2"
    }
};

await blobstoreService.CreateBlobstoreAsync(s3Config);

16.6 本章小结

本章学习了GeoServer的高级功能和扩展服务，包括数据导入、坐标转换、URL验证、密钥管理和Blob存储。
