In-depth research form Submission method: GET / Post Hackfan This article: Windows 2000 Professional Apache 1.3.17 Perl 5.6.1 Internet Explorer 5.00.2920.0000 Do you know that there are GET and POST in the future. I am here to say something here, give you a request for a form submitted by GET: Get /cgi-bin/tech/Method.cgi?get=get http / 1.1accept: image / gif, image / x-xbitmap , Image / JPEG, Image / Pjpeg, Application / VND.ms-PowerPoint, Application / VND.ms-Excel, Application / Msword, * / * Referr: http://localhost//other.htmlaccept-language: en-cnaccept -Encoding: Gzip, DeflateUser-agent: mozilla / 4.0 (compatible; msie 5.01; windows nt 5.0) Host: localhost: 8080connection: Keep-alive This request is issued by this HTML code:

This request has exceeded the scope of our research, and we only study the first line of them. Among them, the first "get" said that the submission is submitted in a GET method; the middle is to submit which program on the server, the front part "/cgi-bin/tech/meth/method.cgi" is our HTML The content of the Action, while the "get = get" is HTML's Form, INPUT content: We found that IE has converted this form to a specific format. In Perl, the data sent in GET is obtained by $ get = $ env {'query_string'}.

Let's take a request for a form submitted in a Post / CGI-BIN/Tech/Method.cgi http / 1.1accept: image / gif, image / x-xbitmap, image / jpeg, image / pjpeg, Application / VND .ms-powerpoint, application / vnd.ms-excel, application / msword, * / * refere: http://localhost//other.htmlaccept-language: en-cncontent-type: Application / X-www-form-urlencodedAccept -Encoding: Gzip, DeflateUser-agent: mozilla / 4.0 (compatible; msie 5.01; windows NT 5.0) Host: localhost: 8080content-length: 9connection: Keep-alive post = post also gives HTML: We found that the data ran to the bottom. In Perl, the data sent in POST is obtained via READ (stdin, $ post, $ env {'content_length'}). I remember that the GET sent data can only be 1024 bytes, and POST seems to be big! Thinking: If I have such an HTML code, what will it happen? This code may be used in many programs, but most people will not think about it, what is the content It is sent in GET, which content is sent in POST.

We look at its request: post /cgi-bin/tech/Method.cgi?get=get http / 1.1accept: image / gif, image / x-xbitmap, image / jpeg, image / pjpeg, Application / VND .ms-powerpoint, application / vnd.ms-excel, application / msword, * / * refere: http://localhost//other.htmlaccept-language: en-cncontent-type: Application / X-www-form-urlencodedAccept -ENCODING: GZIP, DeflateUser-agent: mozilla / 4.0 (compatible; msie 5.01; windows nt 5.0) Host: localhost: 8080content-length: 9connection: Keep-alive post = post Ha! It turned out to be sent in POST. However, you must find some of the data in the first line, just as the GET. In fact, this example is typical, it is POST and GET mixed! Don't believe in you in Perl, use read (stdin, $ post, $ env {'content_length'}) and $ get = env {'query_string'}, which is "get = get" data.

I will give you a device. Everyone goes to study: HTML section: get-post </ title> </ head> <body> <form action = "/ cgi-bin / tech / Method.cgi "Method =" get "> <input type =" text "size =" 10 "value =" get "name =" get "> <input type = submit value =" get mode> </ form> < Form action = "/ cgi-bin / tech / method.cgi" method = "post"> <input type = "text" size = "10" value = "post" name = "post"> <input type = Submit Value = "POST mode"> </ form> <form action = "/ cgi-bin / tech / method.cgi?
