接下来我们开始寻找formhash和seccodehash

在https://www.52hb.com/member.p ... yes&handlekey=login找到了formhash和seccodehash

<input type="hidden" name="formhash" value="f52cd4b4" />

复制代码

<span id="seccode_cSKOblBJ"></span><span class="Apple-tab-span" style="white-space:pre"> </span>

复制代码

接下来我们找验证码

找到了= =

https://www.52hb.com/misc.php?mod=seccode&update=36618&idhash=cSKOblBJ

复制代码

地址是这个
我们看看idhash从哪里来的
idhash就是seccodehash、

复制代码

这个是获取图片的地址

接下来我们就全部找全了
开始做吾爱汇编论坛的post吧

在https://www.52hb.com/member.p ... hash=Lm0Z0&inajax=1
我们发现还有loginhash=Lm0Z0
再找一下

依然在页面里
代码为

我们写代码吧
