openlayers GetFeatureInfo请求示例+虚拟地球/google

我只是从中复制了示例代码

我使用geoserver运行它，一切都像互联网版本一样正常工作，现在我尝试用虚拟地球地图更改政治基础层

由于虚拟地球和谷歌地图的特性，我已经将球形墨卡托设置为真，但在那之后，突出显示功能不再工作

我想我发现了问题所在，我正在创建的向量和其他层之间存在不同的投影，openlayers不知道如何合并它们。 有没有办法将我的向量层从我认为的epsg:4326转换为epsg:900913雪利卡墨卡托

下面是我的代码：

<script src="http://openlayers.org/api/OpenLayers.js"></script>

    .opmap
    {
        height:500px;
        width:550px;
    }
    /* The map and the location bar */
    #map {
        clear: both;
        position: relative;
        width: 400px;
        height: 450px;
        border: 1px solid black;
    }

我不确定你有什么问题

<script src='http://dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=6.1'></script>

那么

这些WMS数据似乎并不正确，除了水，它与虚拟地球地图的映射是正确的

---

我的问题是，如果我从不同于为页面提供服务的服务器请求FeatureInfo，代理会报告错误。

为什么不使用谷歌地图数据时，您的矢量层在EPSG:900913中？为什么不使用谷歌地图数据时，您的矢量层在EPSG:900913中？
