核心提示:下面的代码是自动向cnblogs中的小组发帖.........注意小组ID,主题ID,小组类型首先采用 firebug分析到发帖时的post地址以及参数,其中在headers中包含了cookies,把cookies复制下来放到 d:\\cookie.txt中,以分号隔开(a=b;c=d;),这些cookie中包含有身份

下面的代码是自动向cnblogs中的小组发帖.........注意小组ID,主题ID,小组类型

首先采用 firebug分析到发帖时的post地址以及参数,其中在headers中包含了cookies,把cookies复制下来放到 d:\\cookie.txt中,以分号隔开(a=b;c=d;),这些cookie中包含有身份验证信息

之后读取文件d:\\data.txt,每1024个字节为一帖自动发送
