我想在服务器端使用Grails进行跨源通信。我发现的唯一文档是这一个
I would like to do cross origin communication using Grails in server side. The only documentation that I found is this one
grails/ plugin / cors
但这是一个旧版本的Grails。我发现的其他文档是春天:
but this is for an old version of Grails. The other documentation that I found is for spring:
spring.io/guides/gs/rest-service-cors/
所以我添加了文件 SimpleCorsFilter。 groovy 到 init / myproject / 文件夹,但我不知道如何将此组件连接到 resources.groovy
so I added the file SimpleCorsFilter.groovy to init/myproject/ folder, but I don't know how to wire this component into resources.groovy
推荐答案具体来说,这里有一些代码。注意拦截器名称必须与你的控制器名称(这里是workRequest)匹配,域需要是你调用的任何东西(这里是localhost:8081),它是你想要的before()方法:
To be specific, here is some code that works. Notice the interceptor name must match your controller name (here, workRequest), the domain needs to be whatever you are calling from (here, localhost:8081) and it is the before() method you want:
package rest class WorkRequestInterceptor { boolean before() { header( "Access-Control-Allow-Origin", "localhost:8081" ) header( "Access-Control-Allow-Credentials", "true" ) header( "Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE" ) header( "Access-Control-Max-Age", "3600" ) true } boolean after() { true } }更多推荐
