URLReferer在wap（wml）开发中的应用

来源：互联网发布：自动化编程编辑：程序博客网时间：2024/06/04 18:04

我们在web开发中，经常使用到request集合中的一个元素URLReferer，这个属性是记录当前请求的父请求地址（即记录哪一个地址使得用户点击了链接）。我们通常用于鉴别请求来路、防止盗链等。

而在wml 1.1中，你无法轻松获得，必须使用<go>标签里面的属性 sendreferer

请看摘自wap文档的sendreferer 说明

sendreferer=boolean If this attribute is true, the user agent must specify, for the server's benefit, the URI of the deck containing this task (i.e., the referring deck). This allows a server to perform a form of access control on URIs, based on which decks are linking to them. The URI must be the smallest relative URI possible if it can be relative at all. For example, if sendreferer=true, an HTTP based user agent shall indicate the URI of the current deck in the HTTP "Referer" request header [RFC2616]. method=(post|get) This attribute specifies the HTTP submission method. Currently, the values of get and post are accepted and cause the user agent to perform an HTTP GET or POST respectively.
