要在 Spring Cloud Gateway 中添加 RequestBody 参数,你需要使用 Spring Cloud Gateway 的自定义过滤器来处理请求和响应。下面是一个简单的示例:
```java
@Component
public class RequestBodyFilter implements GlobalFilter, Ordered {
@Override
public Mono<Void> filter(ServerWebExchange exchange, GatewayFilterChain chain) {
ServerHttpRequest request = exchange.getRequest();
MediaType contentType = request.getHeaders().getContentType();
if (contentType != null && contentType.equals(MediaType.APPLICATION_JSON)) {
return DataBufferUtils.join(exchange.getRequest().getBody())
.flatMap(dataBuffer -> {
byte[] bytes = new byte[dataBuffer.readableByteCount()];
dataBuffer.read(bytes);
DataBufferUtils.release(dataBuffer);
String bodyString = new String(bytes, Charset.forName("UTF-8"));
if (StringUtils.isNotBlank(bodyString)) {
exchange.getAttributes().put("cachedRequestBodyObject", bodyString);
}
return chain.filter(exchange);
});
} else {
return chain.filter(exchange);
}
}
@Override
public int getOrder() {
return -1;
}
}
```
此过滤器将检查请求的内容类型是否为 JSON,并将请求体转换为字符串形式,然后将其存储在 Exchange 属性中,以便在后续处理中使用。
你可以在 RouteLocator 中添加此过滤器:
```java
@Bean
public RouteLocator customRouteLocator(RouteLocatorBuilder builder) {
return builder.routes()
.route("test", r -> r.path("/test")
.filters(f -> f.filter(new RequestBodyFilter()))
.uri("http://localhost:8080"))
.build();
}
```
以上代码将在访问 /test 路径时,应用 RequestBodyFilter 过滤器。
