4 parts form, as shown in figure 3, be the general format of request message, wherein, request row is by requesting method field, url field
With 3 field compositions of http protocol version field, they use space-separated.For example, GET/index.html HTTP/1.1.
The requesting method of http protocol has GET, POST, HEAD, PUT, DELETE, OPTIONS, TRACE, CONNECT.It is described herein most
Common GET methods and POST method；Request header is by key/value to forming, and often row is a pair of, and keyword and value are emitted with English
Number ":" separate.Request header notice server is related to the information of client request, and typical request header has：User-Agent：
Generate browser type, the Accept of request：The identifiable content type list of client, Host：The host name of request allows
Multiple domain names exist together an IP address, i.e. fictitious host computer；It is a null after the last one request header, sends the carriage return character and change
Row symbol notifies that there is no request headers below server；Request data does not use in GET methods, but makes in POST method
With.POST method is applicable to the occasion that client fills in list.It is with the relevant most-often used request header of request data
Content-Type and Content-Length.

Byte [] addressBytes=new byte [4]；
buffer.get(addressBytes,0,4)；
DestinationAddress=InetAddress.getByAddress (addressBytes).
The process for performing above-mentioned pseudocode is mainly according to the version number of first 4 definite IP agreements of request message, that is, is sentenced
Disconnected is version for IP v4 or IP v6, currently used more for IP v4, data value 0100；The number of 5-12 is obtained again
According to judging used protocol type, such as tcp agreements, udp agreements with this；32 are obtained shared by destination address afterwards, i.e.,
The data of 4 bytes, and byte arrays addressBytes is converted into IP address, that is, mesh using the java functions provided
Mark address.
In practical applications, often while definite network request message format, according to different field in message
Content and position can be obtained by the associated parameter data in network request, that is, the parsing to the network request.
Finally, which is parsed according to identified message format, obtains the analysis result of the network request.And root
According to above-mentioned example, field distribution of the purpose in each several part in message is determined of network request message format is determined, to network
The parsing of request message is then the process converted by obtaining the data of each several part field.Namely according to message format come
The data of the field of different position in message are obtained, associated parameter data included in network request is obtained with what this came.
204th, obtained analysis result is counted and showed.
