过滤image下载

在测试的时候，有的开发人员只关心自己的程序，并不想测试整个web下载的过程。毕竟image下载是非常耗时的。这个时候，我们就应该要将那些url过滤掉。web_add_auto_filter()这个函数可以帮助我们做到。
下面是关于这个函数的简介。
他包含两个参数：
一、Action：
1.value=include/exclude

二、Attributes:
1.value:

URL - the specific URL to filter

UrlPrefix - Filter all URLs that begin with this string. For example,

"UrlPrefix = http://www.cc"

filters http://www.ccn.com, http://www.cc.edu, http://cc-nanochem.de, and any other URL that begins with "http://www.cc"

Host - URLs which include Host in the hostname portion of the URL path are filtered

HostPrefix - URLs which include this prefix in the hostname portion of the URL path are filtered

HostSuffix - URLs which include this suffix in the host name portion of the URL path are filtered

Path - URLs with the specified path are filtered

PathPrefix - URLs with the specified path prefix are filtered

PathSuffix - URLs with the specified path suffix are filtered

Port - URLs from the specified port are filtered

Scheme - URLs with the specified communications scheme are filtered. Example schemes are http, https and ftp

Query - URLs with the specified query are filtered

QueryPrefix - URLs with the specified query prefix are filtered

QuerySuffix - URLs with the specified query suffix are filtered

FragmentId - URLs containing a matching Fragment ID are filtered

FragmentIdPrefix - URLs containing a matching Fragment ID prefix are filtered

FragmentIdSuffix - URLs containing a matching Fragment ID suffix are filtered

ID: An identifier for use by web_remove_auto_filter.

三、例子

web_add_auto_filter("action=include","urlprefix=http://cnblogs.com/",last);
web_url();
