How to get request body from ServerRequest object in Spring WebFlux reactive?
问题
尝试从使用Postman发送的POST请求中提取到我的Spring应用程序中的请求体。
我尝试过执行以下操作：
ServerRequest.bodyToMono(String.class).toProducer().peek()
但这返回了null。
ServerRequest.bodyToMono(String.class).block() 不再受支持。
还尝试了以下方式：
Mono<String> bodyData = request.bodyToMono(String.class);System.out.println("\nsubscribing to the Mono.....");bodyData.subscribeOn(Schedulers.newParallel("requestBody")).subscribe(value -> {log.debug(String.format("\n value consumed: %s" ,value));});
但我似乎无法在日志中看到任何内容显示出来。

Trying to extract the body of a POST request sent using Postman to my Spring application.
I've tried doing
ServerRequest.bodyToMono(String.class).toProducer().peek()
ServerRequest.bodyToMono(String.class).block() isn't supported anymore.
Also tried doing it this way:
Mono<String> bodyData = request.bodyToMono(String.class);System.out.println("\nsubscribing to the Mono.....");bodyData.subscribeOn(Schedulers.newParallel("requestBody")).subscribe(value -> {log.debug(String.format("%n value consumed: %s" ,value));});
But I can't seem to get anything to show up in the logs.

以下是翻译好的内容：
如果您正在寻找一个示例，展示了一个仅将请求体存储在某个缓存中的反应式 REST 端点，以下示例可以实现这一点：
public class Example implements HandlerFunction<ServerResponse> {private final CacheService cache;@Overridepublic Mono<ServerResponse> handle(ServerRequest request) {return request.bodyToMono(String.class).doOnNext(body -> cache.put(body)).flatMap(body -> ServerResponse.noContent().build());}}
英文:
If you are looking for an example of a reactive rest endpoint that just stores the body in some cache the following example should achieve this
public class Example implements HandlerFunction<ServerResponse> {private final CacheService cache;@Overridepublic Mono<ServerResponse> handle(ServerRequest request) {return request.bodyToMono(String.class).doOnNext(body -> cache.put(body)).flatMap(body -> ServerResponse.noContent().build());}}
