java - 在java中解析http响应字节

Question

我正在尝试用 java 解析 byte[]，它代表 HTTP 响应。有这个问题Is there any simple http response parser for Java? ，这正是我的问题，但接受的答案对我没有帮助。如果我看http://hc.apache.org/httpcomponents-core-ga/httpcore/apidocs/org/apache/http/io/HttpMessageParser.html ，我不明白这对我有什么帮助。

我希望这能让你开始

String s = "HTTP/1.1 200 OK\r\n" +
        "Content-Length: 100\r\n" +
        "Content-Type: text/plain\r\n" +
        "Server: some-server\r\n" +
        "\r\n";
SessionInputBufferImpl sessionInputBuffer = new SessionInputBufferImpl(new HttpTransportMetricsImpl(), 2048);
sessionInputBuffer.bind(new ByteArrayInputStream(s.getBytes(Consts.ASCII)));
DefaultHttpResponseParser responseParser = new DefaultHttpResponseParser(sessionInputBuffer);
HttpResponse response = responseParser.parse();
System.out.println(response);

此代码产生以下输出:

HTTP/1.1 200 OK [Content-Length: 100, Content-Type: text/plain, Server: some-server]
