AbstractMultipartRequest

public AbstractMultipartRequest()

方法详细资料

getFileNames

public Iterator<String> getFileNames()

从接口复制的说明: MultipartRequest

Return an Iterator of String objects containing the parameter names of the multipart files contained in this request. These are the field names of the form (like with normal parameters), not the original file names.

指定者:

getFileNames 在接口中 MultipartRequest

返回:

the names of the files

getFile

public MultipartFile getFile(String name)

从接口复制的说明: MultipartRequest

Return the contents plus description of an uploaded file in this request, or null if it does not exist.

指定者:

getFile 在接口中 MultipartRequest

参数:

name - a String specifying the parameter name of the multipart file

返回:

the uploaded content in the form of a MultipartFile object

getFiles

public List<MultipartFile> getFiles(String name)

从接口复制的说明: MultipartRequest

Return the contents plus description of uploaded files in this request, or an empty list if it does not exist.

指定者:

getFiles 在接口中 MultipartRequest

参数:

name - a String specifying the parameter name of the multipart file

返回:

the uploaded content in the form of a MultipartFile list

multipartData

public List<Multipart> multipartData(String name)

从接口复制的说明: MultipartRequest

Return the contents in this request, or an empty list if it does not exist.

指定者:

multipartData 在接口中 MultipartRequest

参数:

name - a String specifying the parameter name of the multipart

getFileMap

public Map<String,MultipartFile> getFileMap()

从接口复制的说明: MultipartRequest

Return a Map of the multipart files contained in this request.

指定者:

getFileMap 在接口中 MultipartRequest

返回:

a map containing the parameter names as keys, and the MultipartFile objects as values

getMultipartFiles

public cn.taketoday.util.MultiValueMap<String,MultipartFile> getMultipartFiles()

Obtain the MultipartFile Map for retrieval, lazily initializing it if necessary.

指定者:

getMultipartFiles 在接口中 MultipartRequest

返回:

a map containing the parameter names as keys, and a list of MultipartFile objects as values

另请参阅:

• parseRequest()

multipartData

public cn.taketoday.util.MultiValueMap<String,Multipart> multipartData()

从接口复制的说明: MultipartRequest

Get the parts of a multipart request, provided the Content-Type is "multipart/form-data", or an exception otherwise.

指定者:

multipartData 在接口中 MultipartRequest

返回:

the multipart data, mapping from name to part(s)

另请参阅:

• RequestContext.getMultipartRequest()
• MultipartRequest.multipartData()

isResolved

public boolean isResolved()

Determine whether the underlying multipart request has been resolved.

返回:

true when eagerly initialized or lazily triggered, false in case of a lazy-resolution request that got aborted before any parameters or multipart files have been accessed

另请参阅:

• getMultipartFiles()

cleanup

public void cleanup()

从接口复制的说明: MultipartRequest

Cleanup any resources used for the multipart handling, like a storage for the uploaded files.

指定者:

cleanup 在接口中 MultipartRequest

parseRequest

protected abstract cn.taketoday.util.MultiValueMap<String,Multipart> parseRequest()

Lazily initialize the multipart request, if possible. Only called if not already eagerly initialized.
