类 MultipartHttpMessageReader

java.lang.Object

cn.taketoday.http.codec.LoggingCodecSupport

cn.taketoday.http.codec.multipart.MultipartHttpMessageReader

所有已实现的接口:

HttpMessageReader<cn.taketoday.util.MultiValueMap<String,Part>>

public class MultipartHttpMessageReader
extends LoggingCodecSupport
implements HttpMessageReader<cn.taketoday.util.MultiValueMap<String,Part>>

HttpMessageReader for reading "multipart/form-data" requests into a MultiValueMap<String, Part>.

Note that this reader depends on access to an HttpMessageReader<Part> for the actual parsing of multipart content. The purpose of this reader is to collect the parts into a map.

从以下版本开始:

4.0

方法详细资料

getPartReader

public HttpMessageReader<Part> getPartReader()

Return the configured parts reader.

getReadableMediaTypes

public List<MediaType> getReadableMediaTypes()

从接口复制的说明: HttpMessageReader

Return the list of media types supported by this reader. The list may not apply to every possible target element type and calls to this method should typically be guarded via canWrite(elementType, null). The list may also exclude media types supported only for a specific element type. Alternatively, use HttpMessageReader.getReadableMediaTypes(ResolvableType) for a more precise list.

指定者:

getReadableMediaTypes 在接口中 HttpMessageReader<cn.taketoday.util.MultiValueMap<String,Part>>

返回:

the general list of supported media types

canRead

public boolean canRead(cn.taketoday.core.ResolvableType elementType,
 @Nullable
 MediaType mediaType)

从接口复制的说明: HttpMessageReader

Whether the given object type is supported by this reader.

指定者:

canRead 在接口中 HttpMessageReader<cn.taketoday.util.MultiValueMap<String,Part>>

参数:

elementType - the type of object to check

mediaType - the media type for the read (possibly null)

返回:

true if readable, false otherwise

read

public reactor.core.publisher.Flux<cn.taketoday.util.MultiValueMap<String,Part>> read(cn.taketoday.core.ResolvableType elementType,
 ReactiveHttpInputMessage message,
 Map<String,Object> hints)

从接口复制的说明: HttpMessageReader

Read from the input message and decode to a stream of objects.

指定者:

read 在接口中 HttpMessageReader<cn.taketoday.util.MultiValueMap<String,Part>>

参数:

elementType - the type of objects in the stream which must have been previously checked via HttpMessageReader.canRead(ResolvableType, MediaType)

message - the message to read from

hints - additional information about how to read and decode the input

返回:

the decoded stream of elements

readMono

public reactor.core.publisher.Mono<cn.taketoday.util.MultiValueMap<String,Part>> readMono(cn.taketoday.core.ResolvableType elementType,
 ReactiveHttpInputMessage inputMessage,
 Map<String,Object> hints)

从接口复制的说明: HttpMessageReader

Read from the input message and decode to a single object.

指定者:

readMono 在接口中 HttpMessageReader<cn.taketoday.util.MultiValueMap<String,Part>>

参数:

elementType - the type of objects in the stream which must have been previously checked via HttpMessageReader.canRead(ResolvableType, MediaType)

inputMessage - the message to read from

hints - additional information about how to read and decode the input

返回:

the decoded object

toMultiValueMap

private cn.taketoday.util.DefaultMultiValueMap<String,Part> toMultiValueMap(Map<String,Collection<Part>> map)

toList

private List<Part> toList(Collection<Part> collection)
