通过IPv6的HTTP请求 [英] HTTP request over IPv6

问题描述

我想知道使用从IPv4服务器到IPv6服务器的HTTP GET 请求的头格式之间的区别吗？

现在，我正在使用以下格式：

 GET /+ myFileToDownLoad +HTTP / 1.1 \ r \ n+ 
Accept：image / gif，image / x-xbitmap，image / jpeg，image / pjpeg，application / vnd.ms-excel，application / vnd.ms-powerpoint，application / msword ，application / x-shockwave-flash，* / * \r\\\

 +Referer：http：//+ myDstIp +/ \\\
 +Accept -Language：he \r\\\

 +Accept-Encoding：gzip，deflate \r\\\

 +User-Agent：Mozilla / 4.0（compatible; MSIE 6.0; Windows NT 5.0）\r\\\

 // +Host：+ myDstIp +\r\\\

 +Host：+（（myHost == null）？ myDstIp：myHost）+\r\\\

 +Connection：Close \r\\\
\r\\\
; 
  

所以，如果我想使用IPv6服务器，是否需要更改格式？

解决方案

RFC 2732更新Host字段：

在RFC 2396中对语法进行了以下更改：（1）
更改'主机'非终端以添加IPv6选项：

  host = hostname | IPv4地址| IPv6参考
 ipv6reference =[IPv6address]
  

其中IPv6address的定义与RFC2373

因此，您应该将IPv6地址放在方括号中。

<更新：
更改适用于主机部分采用IPv6格式的URL并传播到所有使用原始地址中的'主机'部分的请求字段 - 在您的示例中，这些是主机和推荐人。
也就是说，您必须在 Referrer 和<$ c $>中围绕 myDstIp 添加方括号c>主机字段。

I want to know the difference between the header format of HTTP GET request that uses from IPv4 server to IPv6 server?

Now, currently I am using the following format:

"GET /"+myFileToDownLoad+" HTTP/1.1\r\n"+
            "Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, application/x-shockwave-flash, */*\r\n"
            +"Referer: http://"+myDstIp+"/\r\n"
            +"Accept-Language: he\r\n"
            +"Accept-Encoding: gzip, deflate\r\n"
            +"User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)\r\n"
            //+"Host: "+myDstIp+"\r\n"
            +"Host: "+((myHost==null)?myDstIp:myHost)+"\r\n"
            +"Connection: Close\r\n\r\n";

So, if i want to use the IPv6 server, is it necessary to change the format?

解决方案

RFC 2732 updates the Host field:

The following changes to the syntax in RFC 2396 are made: (1) change the 'host' non-terminal to add an IPv6 option:

  host          = hostname | IPv4address | IPv6reference
  ipv6reference = "[" IPv6address "]"

where IPv6address is defined as in RFC2373 [ARCH].

So you should enclose IPv6 address in square brackets.

Update: The change applies to URLs with host part in IPv6 format and propagates to all request fields that use 'host' part from the original address - in your example these are Host and Referrer. That is, you'll have to add square brackets around myDstIp in Referrer and Host fields.
