Geoserver WMS 风格动态设置

问题描述 投票：0回答：2

我正在尝试使用网站上的用户输入动态设置 Geoserver-WMS 的样式。

我的想法是使用代理脚本创建新的 sld，从地图中删除该图层并添加一个配置有新样式参数的新图层。到目前为止这很好，但似乎我无法相应地设置请求中的 style/sld 参数。

这是我现在正在使用的请求：

https://forestwatch.lup-umwelt.de/app_development/proxy/index.php/geoserver/forestwatch2/wms?SERVICE=WMS&VERSION=1.1.0&REQUEST=GetMap&FORMAT=image%2Fpng&TRANSPARENT=true&LAYERS=forestwatch2%3Astart_veraenderung&TILED=true&STYLE= https%3A%2F%2Fforestwatch.lup-umwelt.de%252Fnew%252FSLD%252F200100.sld&WIDTH=256&HEIGHT=256&SRS=EPSG%3A25832&STYLES=&BBOX=574247.9574719232%2C5665728.63097412 1%2C574920.3574218744%2C5666401.0309240725

XML：

<StyledLayerDescriptor version="1.0.0">
    <UserLayer>
    <sld:LayerFeatureConstraints>
    <sld:FeatureTypeConstraint/>
    </sld:LayerFeatureConstraints>
    <sld:UserStyle>
    <sld:Name>Veraenderungsstart</sld:Name>
    <FeatureTypeStyle>
    <Rule>
    <RasterSymbolizer>
    <ColorMap>
        <ColorMapEntry color="#FFFFFF" quantity="180100"/>
        <ColorMapEntry color="#FF0000" quantity="200100"/>
        <ColorMapEntry color="#800000" quantity="210100"/>
        <ColorMapEntry color="#00FF00" quantity="210101" opacity="1"/>
    </ColorMap>
    </RasterSymbolizer>
    </Rule>
    </FeatureTypeStyle>
    </sld:UserStyle>
    </UserLayer>
</StyledLayerDescriptor>

到目前为止我尝试过的事情：

  • 使用带有 .xml 和 .sld-ending 的同一文件
  • 在请求中使用样式/样式/SLD 参数的两个文件。

问题：

  • 继续使用geoserver中为图层定义的标准样式。

如果有人知道如何在不创建新样式的情况下对图层进行动态样式设置，请告诉我任何帮助，尽管我认为这是不可能的，因为 GeoServer 正在提供 pngs。

编辑1： 这是我当前使用 &sld 而不是 &style 的请求： https://forestwatch.lup-umwelt.de/app_development/proxy/index.php/geoserver/forestwatch2/wms?SERVICE=WMS&VERSION=1.1.0&REQUEST=GetMap&FORMAT=image%2Fpng&TRANSPARENT=true&LAYERS=forestwatch2%3Astart_veraenderung&TILED=true&SLD=https ://forestwatch.lup-umwelt.de/new/SLD/200100.sld&bbox=259026.34190395664,5232194.028899955,930593.5042616761,6111848.605691907&width=586&height=768&srs= EPSG：25832

但是，它返回错误 获取 SLD 时出错。详情请参阅日志。

我更新了我的文件以包含图层名称（使用和不使用工作空间名称进行测试）

<StyledLayerDescriptor version="1.0.0">
<NamedLayer>
<Name>forestwatch2:start_veraenderung</Name>
<UserLayer>
<sld:UserStyle>
<sld:Name>Veraenderungsstart</sld:Name>
<IsDefault>1</IsDefault>
<FeatureTypeStyle>
<Rule>
<RasterSymbolizer>
<ColorMap>
<ColorMapEntry color="#FFFFFF" quantity="180100"/>
<ColorMapEntry color="#FF0000" quantity="200100"/>
<ColorMapEntry color="#00FF00" quantity="210100"/>
<ColorMapEntry color="#800000" quantity="220100"/>
</ColorMap>
</RasterSymbolizer>
</Rule>
</FeatureTypeStyle>
</sld:UserStyle>
</UserLayer>
</NamedLayer>
</StyledLayerDescriptor>

首先，您需要使用“&sld”参数而不是样式。 然后，请注意“图书馆模式”，您可以在这里阅读更多相关信息：

https://docs.geoserver.org/maintain/en/user/styling/sld/working.html#external-styles

简而言之，使用与请求中的图层名称完全相同的NamedLayer，使其

IsDefault=1
。 这是一个工作示例：

https://gs-main.geosolutionsgroup.com/geoserver/wms?service=WMS&version=1.1.0&request=GetMap&layers=tiger:poi&bbox=-74.0118315772888%2C40.70754683896324%2C-74.00153046439813%2C4 0.719885123828675&宽度=641&高度=768&srs =EPSG%3A4326&styles=burg&format=application/openlayers&sld=https://gs-main.geosolutionsgroup.com/geoserver/styles/burg-poi.sld

所以我能够解决我的问题。 .sld 文件与 geoserver 运行在同一台计算机上。因此，如果我将 &sld= 更改为 file:///PATH/TO/SLD/200100.sld 它正在运行。
