篇对xici.net 西祠胡同自动发帖的总结

对于登陆， 上篇博文已经说过了。对于发帖，没有想到还是有点蹊跷，也出现了类似登陆时候的一个code，这个隐藏域的name是h，它的值是引用了2个js，对这个title和content进行了一些处理。我通过对js的下载分析，然后一起把这个代码那给大家，一看就可以用了。如果这个h值错误的话，会报给你“你发的速度太快了，坐下来休息一会。。如此的错误”

post的参数如下，乱码是gbk的编码在firebug下看到乱码：

主要是这个h的获取，我直接把函数贴上来，这个地方的h2函数和上次的不一样：

使用方法就是直接GetCode就好了，3个参数分别是标题，内容和sessionId的值。。

搞了我一整天，这个登陆+发帖。。不过下午还去游泳了，晚上还去吃了滋味烤鱼，整体来说不算累。。。
