解析原始 HTTP 请求 [英] Parsing raw HTTP Request

问题描述

我正在研究由完整的 POST 和 GET 请求组成的 HTTP 流量数据集，如下所示.我已经在 java 中编写了代码，将这些请求中的每一个分开并将其保存为数组列表中的字符串元素.现在我很困惑如何在 java 中解析这些原始 HTTP 请求，有没有比手动解析更好的方法?

I working on HTTP Traffic Data set which is composed of complete POST and GET request Like given below. I have written code in java that has separated each of these request and saved it as string element in array list. Now i am confused how to parse these raw HTTP request in java is there any method better than manual parsing?

GET http://localhost:8080/tienda1/imagenes/3.gif/ HTTP/1.1

推荐答案

我 [正在] 处理 [an] HTTP 流量数据集，该数据集由完整的 POST 和 GET 请求[s] 组成

I [am] working on [an] HTTP Traffic Data set which is composed of complete POST and GET request[s]

所以你想解析一个包含多个 HTTP 请求的文件或列表.你想提取什么数据?反正这里是一个Java HTTP解析类，可以读请求行中使用的方法、版本和 URI，并将所有标头读入 Hashtable.

So you want to parse a file or list that contains multiple HTTP requests. What data do you want to extract? Anyway here is a Java HTTP parsing class, which can read the method, version and URI used in the request-line, and that reads all headers into a Hashtable.

如果您想重新发明轮子，您可以使用它或自己编写一个.查看 RFC 以了解请求在为了正确解析它:

You can use that one or write one yourself if you feel like reinventing the wheel. Take a look at the RFC to see what a request looks like in order to parse it correctly:

Request       = Request-Line              ; Section 5.1
                    *(( general-header        ; Section 4.5
                     | request-header         ; Section 5.3
                     | entity-header ) CRLF)  ; Section 7.1
                    CRLF
                    [ message-body ]          ; Section 4.3
