我开发了一个使用GeoServer的OpenLayers Web应用程序 . 我使用nginx作为我的网络服务器，为GeoServer设置了proxy_pass . 当我使用“localhost”时，一切都按预期工作，但当我切换到我的IP地址时，我得到504网关超时错误

http://98.153.141.207/geoserver/cite/wfs.

我可以访问GeoServer

http://98.153.141.207/geoserver/web

通过浏览器没有问题所以它会出现代理继续按预期工作 .

发生问题时，GeoServer日志会显示以下内容：

Request: describeFeatureType
    service = WFS
    version = 1.1.0
    baseUrl = http://98.153.141.207:80/geoserver/
    typeName[0] = {http://www.opengeospatial.net/cite}MyLayer
    outputFormat = text/xml; subtype=gml/3.1.1

然后一分钟后，我在我的JavaScript控制台中获得了504 Gateway Time-Out，这显示在GeoServer日志中：

09 May 06:02:15 WARN [geotools.xml] - Error parsing: http://98.153.141.207/geoserver/wfs/DescribeFeatureType?version=1.1.0&typename=cite:MyLayer

我在浏览器中尝试了这个假设的问题URL，它运行正常 .

nginx erorr日志包含：

2013/05/09 06:02:15 [error] 420#3844: *54 upstream timed out (10060: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond) while reading response header from upstream, client: 98.153.141.207, server: localhost, request: "GET /geoserver/wfs/DescribeFeatureType?version=1.1.0&typename=cite:MyLayer HTTP/1.1", upstream: "http://127.0.0.1:8080/geoserver/wfs/DescribeFeatureType?version=1.1.0&typename=cite:MyLayer", host: "98.153.141.207"

进一步的调查显示，这个问题似乎仅限于WFS层 . WMS层工作正常 . 这是我的WFS图层失败的声明：

myLayer = new OpenLayers.Layer.Vector("MyLayer",
                                    {
                                      strategies: [new OpenLayers.Strategy.BBOX(),saveStrategy],
                                      projection: "EPSG:2276",
                                      protocol: new OpenLayers.Protocol.WFS(
                                      {
                                        version: "1.1.0",
                                        url: "http://" + hostip + "/geoserver/cite/wfs",
                                        featureNS: "http://www.opengeospatial.net/cite",
                                        srsName: "EPSG:2276",
                                        featureType: "MyLayer",
                                        geometryName: "Poly",
                                        schema: "http://" + hostip + "/geoserver/wfs/DescribeFeatureType?version=1.1.0&typename=cite:MyLayer"
                                      })
                                    });

任何帮助，将不胜感激 . 谢谢

我设法通过从我的图层的OpenLayer.Protocol.WFS中删除“schema”属性来实现此功能 . 任何人都可以解释为什么这会是问题？
