} --------------------编程问答-------------------- 我在eclipse下模拟请求，抓包居然没有抓到post请求！！！

[size=18px]如果大神能帮我发现错误，我回去手抄此代码20遍，发图为证！（我豁出去了）/size]

--------------------编程问答-------------------- 你抓包抓得对的话，那就是在发Post的加断点呗。 --------------------编程问答-------------------- 兄弟啊，加点代码高亮吧！这很不耐看的。。。

我刚去其他板块发了个贴，现在没有编辑功能了！见谅哈！ --------------------编程问答-------------------- 现在还是很难解决啊！ --------------------编程问答-------------------- 楼主登陆的时候没有提示验证码不正吗？ --------------------编程问答--------------------

楼主登陆的时候没有提示验证码不正吗？

没有，直接是返回的信息提示没有登陆，我再登陆的同时抓包，居然没有抓到我请求的post，这不可能啊，兄台，是否愿意加一下我qq272420238 指导一下！不胜感激之！
