CompatibleHttpPostStandardRequestDecoder

public CompatibleHttpPostStandardRequestDecoder(io.netty.handler.codec.http.multipart.HttpDataFactory factory,
                                                io.netty.handler.codec.http.HttpRequest request,

charset - the charset to use as default

抛出:

NullPointerException - for request or charset or factory

io.netty.handler.codec.http.multipart.HttpPostRequestDecoder.ErrorDataDecoderException - if the default charset was wrong when decoding or other errors

方法详细资料

isMultipart

public boolean isMultipart()

True if this request is a Multipart request

指定者:

isMultipart 在接口中 io.netty.handler.codec.http.multipart.InterfaceHttpPostRequestDecoder

返回:

True if this request is a Multipart request

setDiscardThreshold

public void setDiscardThreshold(int discardThreshold)

Set the amount of bytes after which read bytes in the buffer should be discarded. Setting this lower gives lower memory usage but with the overhead of more memory copies. Use 0 to disable it.

指定者:

setDiscardThreshold 在接口中 io.netty.handler.codec.http.multipart.InterfaceHttpPostRequestDecoder

getDiscardThreshold

public int getDiscardThreshold()

Return the threshold in bytes after which read data in the buffer should be discarded.

指定者:

getDiscardThreshold 在接口中 io.netty.handler.codec.http.multipart.InterfaceHttpPostRequestDecoder

getBodyHttpDatas

public List<io.netty.handler.codec.http.multipart.InterfaceHttpData> getBodyHttpDatas()

This getMethod returns a List of all HttpDatas from body.
If chunked, all chunks must have been offered using offer() getMethod. If not, NotEnoughDataDecoderException will be raised.

指定者:

getBodyHttpDatas 在接口中 io.netty.handler.codec.http.multipart.InterfaceHttpPostRequestDecoder

返回:

the list of HttpDatas from Body part for POST getMethod

抛出:

io.netty.handler.codec.http.multipart.HttpPostRequestDecoder.NotEnoughDataDecoderException - Need more chunks

getBodyHttpDatas

public List<io.netty.handler.codec.http.multipart.InterfaceHttpData> getBodyHttpDatas(String name)

This getMethod returns a List of all HttpDatas with the given name from body.
If chunked, all chunks must have been offered using offer() getMethod. If not, NotEnoughDataDecoderException will be raised.

指定者:

getBodyHttpDatas 在接口中 io.netty.handler.codec.http.multipart.InterfaceHttpPostRequestDecoder

返回:

All Body HttpDatas with the given name (ignore case)

抛出:

io.netty.handler.codec.http.multipart.HttpPostRequestDecoder.NotEnoughDataDecoderException - need more chunks

getBodyHttpData

public io.netty.handler.codec.http.multipart.InterfaceHttpData getBodyHttpData(String name)

This getMethod returns the first InterfaceHttpData with the given name from body.
If chunked, all chunks must have been offered using offer() getMethod. If not, NotEnoughDataDecoderException will be raised.

指定者:

getBodyHttpData 在接口中 io.netty.handler.codec.http.multipart.InterfaceHttpPostRequestDecoder

返回:

The first Body InterfaceHttpData with the given name (ignore case)

抛出:

io.netty.handler.codec.http.multipart.HttpPostRequestDecoder.NotEnoughDataDecoderException - need more chunks

offer

public CompatibleHttpPostStandardRequestDecoder offer(io.netty.handler.codec.http.HttpContent content)

Initialized the internals from a new chunk

指定者:

offer 在接口中 io.netty.handler.codec.http.multipart.InterfaceHttpPostRequestDecoder

参数:

content - the new received chunk

抛出:

io.netty.handler.codec.http.multipart.HttpPostRequestDecoder.ErrorDataDecoderException - if there is a problem with the charset decoding or other errors

hasNext

next

public io.netty.handler.codec.http.multipart.InterfaceHttpData next()

Returns the next available InterfaceHttpData or null if, at the time it is called, there is no more available InterfaceHttpData. A subsequent call to offer(httpChunk) could enable more data. Be sure to call ReferenceCounted.release() after you are done with processing to make sure to not leak any resources

指定者:

next 在接口中 io.netty.handler.codec.http.multipart.InterfaceHttpPostRequestDecoder
