为了为Spring GatewayFilter测试生成取消的请求,可以按照以下步骤进行操作:
import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.cloud.gateway.filter.GatewayFilter;
import org.springframework.cloud.gateway.filter.factory.GatewayFilterFactory;
import org.springframework.cloud.gateway.filter.factory.rewrite.RewriteFunction;
import org.springframework.cloud.gateway.route.Route;
import org.springframework.cloud.gateway.route.RouteLocator;
import org.springframework.cloud.gateway.support.ServerWebExchangeUtils;
import org.springframework.http.HttpMethod;
import org.springframework.http.HttpStatus;
import org.springframework.http.server.reactive.ServerHttpRequest;
import org.springframework.test.web.reactive.server.WebTestClient;
import org.springframework.web.server.ServerWebExchange;
import reactor.core.publisher.Mono;
import java.net.URI;
import java.util.Collections;
import java.util.Map;
@SpringBootTest
public class GatewayFilterTest {
@Test
public void testGatewayFilterCancellation() {
// 创建一个测试用的RouteLocator
RouteLocator routeLocator = exchange -> Mono.just(Collections.singletonList(
Route.async()
.id("test-route")
.uri(URI.create("https://example.com"))
.predicate(path -> path.startsWith("/test"))
.filters(gatewayFilter())
.build()
));
// 创建一个WebTestClient用于发送请求
WebTestClient webTestClient = WebTestClient.bindToRouterFunction(routeLocator.build())
.build();
// 发送一个GET请求到/test路径
webTestClient.get().uri("/test")
.exchange()
.expectStatus().isEqualTo(HttpStatus.OK);
// 发送一个POST请求到/test路径
webTestClient.post().uri("/test")
.exchange()
.expectStatus().isEqualTo(HttpStatus.REQUEST_TIMEOUT);
}
private GatewayFilter gatewayFilter() {
return new GatewayFilterFactory<RewriteFunction<RewriteFunction.RequestConfig>, RewriteFunction<RewriteFunction.RequestConfig>>() {
@Override
public GatewayFilter apply(RewriteFunction<RewriteFunction.RequestConfig> config) {
return (exchange, chain) -> {
ServerHttpRequest request = exchange.getRequest();
HttpMethod method = request.getMethod();
if (method == HttpMethod.POST) {
// 如果是POST请求,则取消该请求
ServerWebExchangeUtils.setResponseStatus(exchange, HttpStatus.REQUEST_TIMEOUT);
return Mono.empty();
}
return chain.filter(exchange);
};
}
@Override
public Class<RewriteFunction<RewriteFunction.RequestConfig>> getConfigClass() {
return null;
}
@Override
public RewriteFunction<RewriteFunction.RequestConfig> newConfig() {
return null;
}
}.apply(null);
}
}
testGatewayFilterCancellation
方法,并使用@Test
注解标记该方法为测试方法。testGatewayFilterCancellation
方法中,创建一个测试用的RouteLocator
,并实现其build
方法,返回一个包含测试用路由的列表。WebTestClient
对象,通过bindToRouterFunction
方法绑定RouteLocator
的路由函数。WebTestClient
发送一个GET请求到/test
路径,并验证返回的状态码是否为200。WebTestClient
发送一个POST请求到/test
路径,并验证返回的状态码是否为408(请求超时)。通过以上步骤,即可为Spring GatewayFilter测试生成取消的请求。请注意,以上代码示例中的GatewayFilter
仅用于演示目的,实际使用时可能需要根据具体需求进行修改。
