解析java中的http响应字节 [英] parse http response bytes in java

问题描述

我正在尝试在java中解析 byte [] ，这是HTTP响应的表示。有这个问题 Java有没有简单的http响应解析器？ ，这正是我的问题，但接受的答案对我没有帮助。如果我查看 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。

I'm trying to parse a byte[] in java, which is a representation of an HTTP response. There is this question Is there any simple http response parser for Java?, which is exactly my question, but the accepted answer doesn't help me. If I look at http://hc.apache.org/httpcomponents-core-ga/httpcore/apidocs/org/apache/http/io/HttpMessageParser.html, I do not understand how this will help me.

推荐答案

我希望这能让你入门

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]
