checkNotModified

public Optional<ServerResponse> checkNotModified(Instant lastModified)

从接口复制的说明: ServerRequest

Check whether the requested resource has been modified given the supplied last-modified timestamp (as determined by the application). If not modified, this method returns a response with corresponding status code and headers, otherwise an empty result.

Typical usage:

 public ServerResponse myHandleMethod(ServerRequest request) {
   Instant lastModified = // application-specific calculation
 	 return request.checkNotModified(lastModified)
 	   .orElseGet(() -> {
 	     // further request processing, actually building content
 		 return ServerResponse.ok().body(...);
     });
 }
 

This method works with conditional GET/HEAD requests, but also with conditional POST/PUT/DELETE requests.

Note: you can use either this #checkNotModified(Instant) method; or ServerRequest.checkNotModified(String). If you want to enforce both a strong entity tag and a Last-Modified value, as recommended by the HTTP specification, then you should use ServerRequest.checkNotModified(Instant, String).

指定者:

checkNotModified 在接口中 ServerRequest

参数:

lastModified - the last-modified timestamp that the application determined for the underlying resource

返回:

a corresponding response if the request qualifies as not modified, or an empty result otherwise.

checkNotModified

public Optional<ServerResponse> checkNotModified(String etag)

从接口复制的说明: ServerRequest

Check whether the requested resource has been modified given the supplied ETag (entity tag), as determined by the application. If not modified, this method returns a response with corresponding status code and headers, otherwise an empty result.

Typical usage:

 public ServerResponse myHandleMethod(ServerRequest request) {
   String eTag = // application-specific calculation
 	 return request.checkNotModified(eTag)
 	   .orElseGet(() -> {
 	     // further request processing, actually building content
 		 return ServerResponse.ok().body(...);
     });
 }

This method works with conditional GET/HEAD requests, but also with conditional POST/PUT/DELETE requests.

Note: you can use either this ServerRequest.checkNotModified(Instant) method; or #checkNotModified(String). If you want to enforce both a strong entity tag and a Last-Modified value, as recommended by the HTTP specification, then you should use ServerRequest.checkNotModified(Instant, String).

指定者:

checkNotModified 在接口中 ServerRequest

参数:

etag - the entity tag that the application determined for the underlying resource. This parameter will be padded with quotes (") if necessary.

返回:

a corresponding response if the request qualifies as not modified, or an empty result otherwise.

checkNotModified

public Optional<ServerResponse> checkNotModified(Instant lastModified,
 String etag)

从接口复制的说明: ServerRequest

Check whether the requested resource has been modified given the supplied ETag (entity tag) and last-modified timestamp, as determined by the application. If not modified, this method returns a response with corresponding status code and headers, otherwise an empty result.

Typical usage:

 public ServerResponse myHandleMethod(ServerRequest request) {
   Instant lastModified = // application-specific calculation
   String eTag = // application-specific calculation
 	 return request.checkNotModified(lastModified, eTag)
 	   .orElseGet(() -> {
 	     // further request processing, actually building content
 		 return ServerResponse.ok().body(...);
     });
 }

This method works with conditional GET/HEAD requests, but also with conditional POST/PUT/DELETE requests.

指定者:

checkNotModified 在接口中 ServerRequest

参数:

lastModified - the last-modified timestamp that the application determined for the underlying resource

etag - the entity tag that the application determined for the underlying resource. This parameter will be padded with quotes (") if necessary.
