Question

我有一个reactjs前端，它基于spring-integration向我的api发送一个请求。

我遇到的问题是，我不知道如何在网关中绑定CORS功能。

我尝试过这样的事情

  @Bean
    public CrossOrigin cors(){
        CrossOrigin c = new CrossOrigin();
        c.setOrigin("/**");
        return c;
    }

@Bean
    public IntegrationFlow httpGetTest() {
        return IntegrationFlows.from(httpGetGateTest()).channel("http.test.channel").handle("testEndpoint", "hello").get();
    }

@Bean
    public MessagingGatewaySupport httpGetGateTest() {
        HttpRequestHandlingMessagingGateway handler = new HttpRequestHandlingMessagingGateway();
        handler.setRequestMapping(createMapping(new HttpMethod[]{HttpMethod.GET}, "/test"));
        handler.setCrossOrigin(cors());
        handler.setHeaderMapper(headerMapper());
        return handler;
    }

请求：

axios.get('http://localhost:8080/test')
    .then(res=>{console.log(res)})

我的端点返回“ Hello World”

Failed to load resource: the server responded with a status of 415 ()

Access to XMLHttpRequest at 'http://localhost:8080/test' from origin 'http://localhost:3000' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

首先，请确保您的客户端确实发送了//This my code for delete $listening = Listening::find($id); if ($listening->audio !== $request->audio) { unlink(public_path('listening/admin/'.$listening->audio)); } HTTP请求标头。否则，CORS过滤将不会应用于请求：https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS

尽管听起来好像仍然存在：Origin。

请考虑将您的from origin 'http://localhost:3000'更改为setOrigin("/**")。跨域策略是关于整个ULR（准确地说是域），而不是相对路径。

顺便说一句，Spring Integration中有一个Java DSL工厂用于HTTP组件：

setOrigin("*")

如何在我的http网关（spring-integration-dsl）中添加CORS功能？
