请教:http 协议中的 GET 语法

bobo123(bobo)
使用SOCKET 访问WEB SERVER 时候,中涉及到GET 和POST 的使用

其中访问WEB SERVER 中的WEB PAGE时候,后跟参数,其中有一项参数是
很长的字符串.

假设:
要访问的网页面是:
www.rolia.net/update.asp?sSql= select id from rolia.dbo.User_id
那么GET 语法怎么写?
我试验了以下
GET /update.asp?sSql=select id from rolia.dbo.User_id HTTP/1.0\r\nContent-Length: 0\r\n\r\n

但是反馈回来的错误的:
HTTP/1.1 400 Bad Request\r\nServer: Microsoft-IIS/5.0\r\nDate: Fri, 14 May 2004 19:37:34 GMT\r\nContent-Type: text/html\r\nContent-Length: 87\r\n\r\n<html><head><title>Error</title></head><body>The parameter is incorrect. </body></html>

      • below is the result, i tried. it can get web page. but wrong page. I think, it may caused by cookie problem. if i disable cookie of IE, I may get same page in IE. -647i(aaaa); 2004-5-18 {1291} (#1729348@0)

    • 其实是把URL 中有空格的字符要写成%20 就可以了,其它有一些非字母的字符也要相应的转换. -bobo123(bobo); 2004-5-19 (#1729938@0)
