ArcgisServer跨域问题

1：Arcgiserver在火狐和谷歌浏览器下会因为JS同源策略导致请求被拦截，解决办法是在后端直接进行CORS配置,开放出地址给其他客户端。

2：配置方法

• 找到arcgisServer的安装路径下的tomcat容器

 <arcgis_server_home>\framework\runtime\tomcat

• 下载必要的两个CORS 包，并添加进tomcat根目录下的lib目录中

cors-filter-1.7.jar ,java-property-utils-1.9.jar

• 修改config目录下的Web.xml文件，添加Filter

<filter>
    <filter-name>CORS</filter-name>
    <filter-class>com.thetransactioncompany.cors.CORSFilter</filter-class>
    <init-param>
        <param-name>cors.allowOrigin</param-name>
        <param-value>*</param-value>
    </init-param>
    <init-param>
        <param-name>cors.supportedMethods</param-name>
        <param-value>GET, POST, HEAD, PUT, DELETE</param-value>
    </init-param>
    <init-param>
        <param-name>cors.supportedHeaders</param-name>
        <param-value>Accept, Origin, X-Requested-With, Content-Type, Last-Modified</param-value>
    </init-param>
    <init-param>
        <param-name>cors.exposedHeaders</param-name>
        <param-value>Set-Cookie</param-value>
    </init-param>
    <init-param>
        <param-name>cors.supportsCredentials</param-name>
        <param-value>true</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>CORS</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

• 重新启动ArcgisServer服务即可。（ArcgisServer服务启动时间比较长，需耐心等候url可以正常访问）
