Openlayers 3 通过OpenLayers 3将SLD应用于WMS层

我想动态更改WMS层的SLD。我可以通过STYLES参数应用Geoserver保存的SLD，但当我想通过SLD_BODY应用SLD时，它会发送请求，但不会发生任何事情。我认为一切都很好，但SLD不适用于图层。代码如下：

var SLD = '<?xml version="1.0" encoding="UTF-8"?>'+
'<StyledLayerDescriptor version="1.0.0" xmlns="http://www.opengis.net/sld" xmlns:ogc="http://www.opengis.net/ogc"'+
    'xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"'+
    'xsi:schemaLocation="http://www.opengis.net/sld http://schemas.opengis.net/sld/1.0.0/StyledLayerDescriptor.xsd">'+
    '<NamedLayer>'+
    '<Name>pmo:'+ layer.Name + '</Name>'+
    '<UserStyle>'+
        '<Name>pmo:' + layer.Name + '</Name>' +
        '<Title>A small red flag</Title>'+
        '<Abstract>A sample of how to use an SVG based symbolizer</Abstract>'+
        '<FeatureTypeStyle>'+
        '<Rule>'+
            '<Title>Red flag</Title>'+
            '<PointSymbolizer>'+
            '<Graphic>'+
                '<ExternalGraphic>'+
                '<OnlineResource xlink:type="simple" xlink:href="burg02.svg" />'+
                '<Format>image/svg+xml</Format>'+
                '</ExternalGraphic>'+
                '<Size>'+
                '<ogc:Literal>20</ogc:Literal>'+
                '</Size>'+
            '</Graphic>'+
            '</PointSymbolizer>'+
        '</Rule>'+
        '</FeatureTypeStyle>'+
    '</UserStyle>'+
    '</NamedLayer>'+
    '</StyledLayerDescriptor>';
    SLD = encodeURI(SLD);

    var source = layer.WMSLayer.getSource();
    source.updateParams({ 'STYLES': '' ,'SLD_BODY': SLD });

var SLD=''+

“pmo:”+层名称+“”+

'';
SLD=编码URI（SLD）；
var source=layer.WMSLayer.getSource（）；
updateParams（{'STYLES'：''，'SLD_BODY'：SLD}）；

请更换您的sld

我将样式更改为未定义，我将请求发送到Geoserver，得到以下错误：java.lang.RuntimeException:org.xml.sax.SAXParseException；lineNumber我调试字符串，这是因为我发送了#字符作为颜色。我不知道该如何将itI更改的样式更正为未定义，我将请求发送到Geoserver，得到以下错误：java.lang.RuntimeException:org.xml.sax.saxpasseeption；lineNumber我调试字符串，这是因为我发送了#字符作为颜色。我不知道该怎么纠正它
