方法详细资料

isFormUrlEncoder

public static boolean isFormUrlEncoder(String contentType)

removeHeaderUnSupportTrailer

public static void removeHeaderUnSupportTrailer(io.netty.handler.codec.http.LastHttpContent lastHttpContent)

移除头部不支持拖挂的字段

参数:

lastHttpContent - 最后一次内容

isAcceptTransferChunked

public static boolean isAcceptTransferChunked(io.netty.handler.codec.http.HttpHeaders headers)

是否接受分段传输

参数:

headers - headers

返回:

boolean

isKeepAlive

public static boolean isKeepAlive(io.netty.handler.codec.http.HttpRequest message)

Returns true if and only if the connection can remain open and thus 'kept alive'. This methods respects the value of the "Connection" header first and then the return value of HttpVersion.isKeepAliveDefault().

参数:

message - message

返回:

boolean isKeepAlive

setKeepAlive

public static void setKeepAlive(io.netty.handler.codec.http.HttpResponse message,
                                boolean keepAlive)

Sets the value of the "Connection" header depending on the protocol version of the specified message. This getMethod sets or removes the "Connection" header depending on what the default keep alive mode of the message's protocol version is, as specified by HttpVersion.isKeepAliveDefault().

• If the connection is kept alive by default:
  • set to "close" if keepAlive is false.
  • remove otherwise.
• If the connection is closed by default:
  • set to "keep-alive" if keepAlive is true.
  • remove otherwise.

参数:

message - message

keepAlive - keepAlive

isUnsupportedExpectation

public static boolean isUnsupportedExpectation(io.netty.handler.codec.http.HttpMessage message)

getContentLength

public static long getContentLength(io.netty.handler.codec.http.HttpMessage message,
                                    long defaultValue)

Returns the length of the content. Please note that this value is not retrieved from ByteBufHolder.content() but from the "Content-Length" header, and thus they are independent from each other.

参数:

message - message

defaultValue - defaultValue

返回:

the content length or defaultValue if this message does not have the "Content-Length" header or its value is not a number

setContentLength

public static void setContentLength(io.netty.handler.codec.http.HttpHeaders headers,
                                    long length)

Sets the "Content-Length" header.

参数:

headers - headers

length - length

is100ContinueExpected

public static boolean is100ContinueExpected(io.netty.handler.codec.http.HttpRequest message)

参数:

message - message

返回:

is100ContinueExpected

set100ContinueExpected

public static void set100ContinueExpected(io.netty.handler.codec.http.HttpMessage message,
                                          boolean expected)

Sets or removes the "Expect: 100-continue" header to / from the specified message. If the specified value is true, the "Expect: 100-continue" header is set and all other previous "Expect" headers are removed. Otherwise, all "Expect" headers are removed completely.

参数:

message - message

expected - expected

isTransferEncodingChunked

public static boolean isTransferEncodingChunked(io.netty.handler.codec.http.HttpHeaders headers)

Checks to see if the transfer encoding in a specified HttpMessage is chunked

参数:

headers - The message to check

返回:

True if transfer encoding is chunked, otherwise false

setTransferEncodingChunked

public static void setTransferEncodingChunked(io.netty.handler.codec.http.HttpHeaders headers,
                                              boolean chunked)

Sets the block transport header
