我编写了一个HttpContent类,主要用于保存爬取网页的源码,返回状态和编码格式信息,他在mapper中别实例化保存网页内容,然后传输到reducer中被使用,在编写中遇到了一些问题: (1)首先是没有编写默认的构造函数类...下面是HttpContent的类型的源码,重点是write(DataOutput out)和readFields(DataInput in)方法: package bbs.http; import java.io.DataInput...java.io.UnsupportedEncodingException; import org.apache.hadoop.io.Writable; /** * */ public class HttpContent...(){ } public HttpContent(byte[] content, int status, String encoding) { this.content = content;...void readFields(DataInput in) throws IOException { int size=in.readInt(); // System.out.println("HttpContent
request.getUri(); System.out.println("Uri:" + uri); } if (msg instanceof HttpContent...) { HttpContent content = (HttpContent) msg; ByteBuf buf = content.content();...io.netty.channel.ChannelHandlerContext; import io.netty.channel.ChannelInboundHandlerAdapter; import io.netty.handler.codec.http.HttpContent...CONTENT_TYPE:" + response.headers().get(HttpHeaders.Names.CONTENT_TYPE)); } if(msg instanceof HttpContent...) { HttpContent content = (HttpContent)msg; ByteBuf buf = content.content
netty中的HTTP请求可以分成两个部分,分别是HttpRequest和HttpContent。...其中HttpRequest只包含了请求的版本号和消息头的信息,HttpContent才包含了真正的请求内容信息。...但是如果要构建一个请求的话,需要同时包含HttpRequest和HttpContent的信息。...如果读取的消息是HttpContent,那么将content的内容添加到buffer中: if (msg instanceof HttpContent) { HttpContent...httpContent = (HttpContent) msg; ByteBuf content = httpContent.content(); if
addproductspudto.SKUImages.Add(imgbytes); string json = JsonConvert.SerializeObject(addproductspudto); HttpContent...httpcontent = new StringContent(json); httpcontent.Headers.ContentType = new MediaTypeHeaderValue..."); var response = httpclient.PostAsync("http://localhost:2209/api/Product/AddProduct", httpcontent...httpcontent = new StringContent(json); httpcontent.Headers.ContentType = new MediaTypeHeaderValue..."); var response = httpclient.PostAsync("http://localhost:2209/api/Product/AddProduct", httpcontent
version = "1.0", }; var data = JsonConvert.SerializeObject(d); HttpContent...httpContent = new StringContent(data); httpContent.Headers.ContentType = new MediaTypeHeaderValue...{ string responseJson = httpClient.PostAsync("http://192.168.8.178:1646/token", httpContent...new byte[0])) { using (HttpContent content = new StreamContent(dataStream
对于GET请求来说,因为所有的内容都包含在URI中,所以不需要额外的HTTPContent,直接发送HttpRequest到服务器就可以了。...=').append(attrVal).append("\r\n"); } } POST方法上传数据 对于POST请求,它比GET请求多了一个HTTPContent...如果是HttpContent,我们将解析的结果放到一个StringBuilder中缓存起来,等接收到LastHttpContent再一起发送出去即可。...在收到HttpContent之后,我们调用decoder.offer方法,对HttpContent进行解码: decoder.offer(chunk); 在decoder内部有两个存储HttpData...channel.write(request); 要注意,如果是transfer-encoding = chunked,那么这个HttpRequest只是请求头的信息,我们还需要手动将HttpContent

//返回 System.Net.Http.HttpContent。 HTTP 响应消息的内容。...public HttpContent Content { get; set; } //获取 HTTP 响应标头的集合。...HttpResponseMessage.Content属性的类型为HttpContent,其定义如下: public abstract class HttpContent : IDisposable {...public HttpContentHeaders Headers { get; } //其他代码略 } HttpContent.Headers 属性 其的定义如下: public sealed...httpContent, TransportContext transportContext) { try {
Field21", Field22 = "Field21" }, new { Field21 = "Field21", Field22 = "Field21" } }, Name = "Tests" }; HttpContent...调用接口2传参的方式有两种 第一种方法:采用FormUrlEncodedContent将请求输入写入消息体中 HttpContent content = new FormUrlEncodedContent...); } 第二种方法:采用StringContent将请求数据写入消息体中 var model = new { Field21 = "Field21", Field22 = "Field22" }; HttpContent

write(ChannelHandlerContext ctx, Object message, ChannelPromise promise) { if (message instanceof HttpContent...) { // Transform HttpContent to ByteBuf....HttpContent content = (HttpContent) message; try { ByteBuf transformed = ctx.alloc...promise); } finally { content.release(); } } else { // Pass non-HttpContent
继承这个类的对象有两个非常重要的对象,分别是HttpMessage和HttpContent。...而具体请求的内容是在HttpContent中,HttpContent继承自ByteBufHolder,表示它中间可以带有ByteBuf的内容信息。...而HttpContent真正的实现类就是DefaultFullHttpRequest和DefaultFullHttpResponse,这两个内包含了HTTP头和HTTP请求响应内容信息。...当然,如果你的客户端没有这种请求,那么可以直接使用HttpObjectAggregator来将HttpMessage和HttpContent和合并成为FullHttpRequest或者FullHttpResponse
URI:" + request.getUri()); System.err.println(msg); } if (msg instanceof HttpContent...) { LastHttpContent httpContent = (LastHttpContent) msg; ByteBuf byteData = httpContent.content
HTTP 报文,在msg instance of HttpRequest情况下我们拿到的是请求行与请求头(这里简称请求头吧),下一次再来到channelRead0中,且msg instance of HttpContent...import static io.netty.handler.codec.http.HttpVersion.HTTP_1_1; import io.netty.handler.codec.http.HttpContent...DefaultHttpRequest request = (DefaultHttpRequest) currentRequestField.get(handler); HttpContent...chunk = (HttpContent) msg; //currentDecoder not null meaning method is POST and body...httpContent = (HttpContent) msg; currentHttpPostRequestDecoder.offer(httpContent);
ChannelHandler 企业微信截图_15626423204963.png HttpClientCodec和HttpServerCodec:HttpClientCodec负责将请求字节解码为HttpRequest、HttpContent...和LastHttpContent消息,以及对应的转为字节;HttpServerCodec负责服务端中将字节码解析成HttpResponse、HttpContent和LastHttpContent消息,以及对应的将它转为字节
HTTP Request 第一部分是包含的头信息 HttpContent 里面包含的是数据,可以后续有多个 HttpContent 部分 LastHttpContent 标记是 HTTP request...HTTP response 第一部分是包含的头信息 HttpContent 里面包含的是数据,可以后续有多个 HttpContent 部分 LastHttpContent 标记是 HTTP response
