geoserver跨域

跨域问题是指在一个域下的网页去请求另一个域下的资源时，由于浏览器的同源策略限制，导致请求失败的问题。而Geoserver跨域问题则是指在使用Geoserver时，由于Geoserver默认不允许跨域请求，因此在前端页面请求Geoserver服务时会出现跨域问题。解决Geoserver跨域问题的方法如下：

1.在Geoserver的web.xml文件中添加以下内容：

<filter>
    <filter-name>cross-origin</filter-name>
    <filter-class>org.eclipse.jetty.servlets.CrossOriginFilter</filter-class>
    <init-param>
        <param-name>allowedOrigins</param-name>
        <param-value>*</param-value>
    </init-param>
    <init-param>
        <param-name>allowedMethods</param-name>
        <param-value>GET,POST,PUT,DELETE,HEAD</param-value>
    </init-param>
    <init-param>
        <param-name>allowedHeaders</param-name>
        <param-value>*</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>cross-origin</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

2.在Geoserver的安装目录下的webapps/geoserver/WEB-INF/web.xml文件中添加以下内容：

<filter>
    <filter-name>cross-origin</filter-name>
    <filter-class>org.eclipse.jetty.servlets.CrossOriginFilter</filter-class>
    <init-param>
        <param-name>allowedOrigins</param-name>
        <param-value>*</param-value>
    </init-param>
    <init-param>
        <param-name>allowedMethods</param-name>
        <param-value>GET,POST,PUT,DELETE,HEAD</param-value>
    </init-param>
    <init-param>
        <param-name>allowedHeaders</param-name>
        <param-value>*</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>cross-origin</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

3.在Geoserver的安装目录下的webapps/geoserver/WEB-INF/web.xml文件中添加以下内容：

<filter>
    <filter-name>cross-origin</filter-name>
    <filter-class>org.eclipse.jetty.servlets.CrossOriginFilter</filter-class>
    <init-param>
        <param-name>allowedOrigins</param-name>
        <param-value>*</param-value>
    </init-param>
    <init-param>
        <param-name>allowedMethods</param-name>
        <param-value>GET,POST,PUT,DELETE,HEAD</param-value>
    </init-param>
    <init-param>
        <param-name>allowedHeaders</param-name>
        <param-value>*</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>cross-origin</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>
