【问题描述】：

嗨，根据question ，我编写了将 Store 和 ShapeFile 添加到 Geoserver 的方法，这些方法可以正常工作，但是当获得图层预览时说 bbox 不正确

非法bbox，minX: 0.0 大于maxX: -1.0

当我从地理服务器 Web 界面手动更改时添加 shapefile 后，它可以正常工作，但我想以编程方式 这是我的代码

 public bool UploadShapeFile()
    

        var uploads = Path.Combine(_host.WebRootPath, "Upload");
        var filePath = Path.Combine(uploads, "states_25.zip");
        string result = Path.GetFileNameWithoutExtension(filePath);
        String fileUri = filePath;
        Console.Write(fileUri);

        byte[] localShapeFile = readLocalShapeFile(fileUri);

        String sUrl = "http://192.168.1.2:8080/geoserver/rest/workspaces" +
            "/sf/datastores/sf3/file.shp";

        WebRequest request = WebRequest.Create(sUrl);

        request.ContentType = "application/zip";
        request.Method = "PUT";
        request.Credentials = new NetworkCredential("admin", "geoserver");

        Stream requestStream = request.GetRequestStream();
        requestStream.Write(localShapeFile, 0, localShapeFile.Length);
        requestStream.Close();

        WebResponse response = request.GetResponse();
        CreatePostGISTableAndFeatureType();
        return true;
    

    public bool CreatePostGISTableAndFeatureType()
    
        string featXml = GetXml();
        string fUrl =   "http://192.168.1.2:8080/geoserver/rest/workspaces" +
            "/sf/datastores/sf3/featuretypes";

        WebRequest request = WebRequest.Create(fUrl);
        request.Method = "POST";
        request.ContentType = "application/xml";
        request.Credentials = new NetworkCredential("admin", "geoserver");

        byte[] buffer = Encoding.GetEncoding("UTF-8").GetBytes(featXml);

        Stream requestStream = request.GetRequestStream();
        requestStream.Write(buffer, 0, buffer.Length);
        requestStream.Close();
        try
        
            WebResponse response = request.GetResponse();
        
        catch (Exception ee)
        

        


        return false;
    
    private string GetXml()
    
        string fXml = "<featureType>" +

    private byte[] readLocalShapeFile(string filePath)
    
        byte[] buffer;
        FileStream fStream = new FileStream(filePath, FileMode.Open, FileAccess.Read);
        try

            buffer = new byte[length];
            int count;
            int sum = 0;

            while ((count = fStream.Read(buffer, sum, length - sum)) > 0)
                sum += count;
        
        finally
        
            fStream.Close();
        

        return buffer;
    

非常感谢您的关注

【参考方案1】：

您需要在PUT 发送到服务器的 XML 文件中指定数据集的边界框，或者在请求中包含 recalculate 选项。

查看REST Manual了解完整详情：

重新计算数组字符串

指定是否重新计算特征类型的任何边界框。必要时会自动重新计算要素类型的某些属性。特别是，当投影或投影策略改变时重新计算原生边界框，当重新计算原生边界框或在请求中显式提供新的原生边界框时，重新计算纬度/经度边界框。 （本机和纬度/经度边界框在明确包含在请求中时不会自动重新计算。）此外，客户端可以明确请求一组固定的字段进行计算，方法是在其中包含以逗号分隔的名称列表重新计算参数。空参数“recalculate=”有助于避免在对大型数据集进行操作时缓慢重新计算，因为“recalculate=”可以避免计算任何字段，无论投影、投影策略等如何更改。nativebbox 参数“recalculate=nativebbox”用于重新计算本地边界框，同时避免重新计算纬度/经度边界框。重新计算参数可以一起使用 - 可以在批量导入后使用“recalculate=nativebbox,latlonbbox”来重新计算本地边界框和纬度/经度边界框。
