HttpClientCodec (Netty 4.1.109.Final API文档

java.lang.Object
- io.netty.channel.ChannelHandlerAdapter
- - io.netty.channel.ChannelInboundHandlerAdapter
  - - io.netty.channel.ChannelDuplexHandler
    - - io.netty.channel.CombinedChannelDuplexHandler<HttpResponseDecoder,HttpRequestEncoder>
      - io.netty.handler.codec.http.HttpClientCodec

所有已实现的接口:

ChannelHandler, ChannelInboundHandler, ChannelOutboundHandler, HttpClientUpgradeHandler.SourceCodec
```
public final class HttpClientCodec
extends CombinedChannelDuplexHandler<HttpResponseDecoder,HttpRequestEncoder>
implements HttpClientUpgradeHandler.SourceCodec
```
A combination of HttpRequestEncoder and HttpResponseDecoder which enables easier client side HTTP implementation. HttpClientCodec provides additional state management for HEAD and CONNECT requests, which HttpResponseDecoder lacks. Please refer to HttpResponseDecoder to learn what additional state management needs to be done for HEAD and CONNECT and why HttpResponseDecoder can not handle it by itself.
If the Channel is closed and there are missing responses, a PrematureChannelClosureException is thrown.
Header Validation
It is recommended to always enable header validation.
Without header validation, your system can become vulnerable to CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting') .
This recommendation stands even when both peers in the HTTP exchange are trusted, as it helps with defence-in-depth.

构造器概要

构造器
构造器和说明
`HttpClientCodec()` Creates a new instance with the default decoder options (`maxInitialLineLength (4096)`, `maxHeaderSize (8192)`, and `maxChunkSize (8192)`).
`HttpClientCodec(HttpDecoderConfig config, boolean parseHttpAfterConnectRequest, boolean failOnMissingResponse)` Creates a new instance with the specified decoder options.
`HttpClientCodec(int maxInitialLineLength, int maxHeaderSize, int maxChunkSize)` Creates a new instance with the specified decoder options.
`HttpClientCodec(int maxInitialLineLength, int maxHeaderSize, int maxChunkSize, boolean failOnMissingResponse)` Creates a new instance with the specified decoder options.
`HttpClientCodec(int maxInitialLineLength, int maxHeaderSize, int maxChunkSize, boolean failOnMissingResponse, boolean validateHeaders)` 已过时。 Prefer the `HttpClientCodec(int, int, int, boolean)` constructor, to always enable header validation.
`HttpClientCodec(int maxInitialLineLength, int maxHeaderSize, int maxChunkSize, boolean failOnMissingResponse, boolean validateHeaders, boolean parseHttpAfterConnectRequest)` 已过时。 Prefer the `HttpClientCodec(HttpDecoderConfig, boolean, boolean)` constructor, to always enable header validation.
`HttpClientCodec(int maxInitialLineLength, int maxHeaderSize, int maxChunkSize, boolean failOnMissingResponse, boolean validateHeaders, int initialBufferSize)` 已过时。 Prefer the `HttpClientCodec(HttpDecoderConfig, boolean, boolean)` constructor, to always enable header validation.
`HttpClientCodec(int maxInitialLineLength, int maxHeaderSize, int maxChunkSize, boolean failOnMissingResponse, boolean validateHeaders, int initialBufferSize, boolean parseHttpAfterConnectRequest)` 已过时。 Prefer the `HttpClientCodec(HttpDecoderConfig, boolean, boolean)` constructor, to always enable header validation.
`HttpClientCodec(int maxInitialLineLength, int maxHeaderSize, int maxChunkSize, boolean failOnMissingResponse, boolean validateHeaders, int initialBufferSize, boolean parseHttpAfterConnectRequest, boolean allowDuplicateContentLengths)` 已过时。 Prefer the `HttpClientCodec(HttpDecoderConfig, boolean, boolean)` constructor, to always enable header validation.
`HttpClientCodec(int maxInitialLineLength, int maxHeaderSize, int maxChunkSize, boolean failOnMissingResponse, boolean validateHeaders, int initialBufferSize, boolean parseHttpAfterConnectRequest, boolean allowDuplicateContentLengths, boolean allowPartialChunks)` 已过时。 Prefer the `HttpClientCodec(HttpDecoderConfig, boolean, boolean)` constructor, to always enable header validation.
