具体 postdata 为啥那么长，我也很纳闷我是不是搞错了！
但这个网站竟然将网页全文做为一个变量用 js submit 传送了！！

大虾帮忙分析下，这个 URL 的 post 我这样做对不对！

data 去哪儿了？

你的 postdata 根本就没用过。。不懂你是要干什么。。

抱歉，刚修改了，直接复制了！
这样也不行的

@trotyl 源码复制时错了，抱歉

__VIEWSTATE 这个参数值是动态的吧？
dsp2138
2016-03-12 18:50:03 +08:00
@crab 这个我 base64 解码看了下，就是当前页的全文的 html 代码！
具体为啥这么做很是不理解！

heasers 不全？

@xuzywozz 我应该把 get 得到的 headers 都添加上吗？
bdbai
2016-03-12 21:23:19 +08:00
这一大串是 ASP.NET WebForm 生成的。你可以直接访问页面得到那串东西，然后模拟浏览器请求 POST 这样也许会好一点。

@dsp2138 全加上试试 我遇到几次问题都是 headers 不全造成的
dsp2138
2016-03-12 21:47:47 +08:00
@bdbai 我大概也看明白了， cookies 里面的__CSRFCOOKIE ，和 data 里面的__CSRFTOKEN 是保持一致的！
只是__CSRFTOKEN 的 value 使用了 base64 加密，但又不完全是！__CSRFCOOKIE 的 base64 码和__CSRFTOKEN 不一致！正在琢磨呢

@just1 请教，哪些是不能加的？本人对这方面学习甚少！
谢谢
