谢谢了。还有个问题请教，为什么post的数据跟网页上返回的数据不一样。
W@lf(326335) 10:45:57

post参数都正确。。

有没有cookie啊

[北京]SillyPGM(1545415453) 10:50:08

注意了木有

[北京]SillyPGM(1545415453) 10:50:18

有没有动态参数

W@lf(326335) 10:50:22

不用cookies的

W@lf(326335) 10:50:30

值都是固定的。

[郑州] 站长苏飞<sufei.1013@163.com> 10:51:00

得到的数据不完整，还是不对，你直接访问查看源码和使用HttpHelper类访问比较一下，

[重庆]Eagle(838010363) 10:51:16

苏飞

[北京]SillyPGM(1545415453) 10:51:27

post数据的日期怎么和referer不一样

[重庆]Eagle(838010363) 10:51:38

你的那个类传ip你是怎么设定的

[北京]SillyPGM(1545415453) 10:51:40

一个是18号，一个是20号

W@lf(326335) 10:51:51

这个是网页的

[重庆]Eagle(838010363) 10:51:53

设置代理那里

W@lf(326335) 10:52:03

[郑州] 站长苏飞<sufei.1013@163.com> 10:52:26

代理的IP是直接在HttpItem里，不过那块我没测试过，呵呵

[北京]SillyPGM(1545415453) 10:52:38

那么postdata不对的

[重庆]Eagle(838010363) 10:52:42

真讨厌发源码

W@lf(326335) 10:53:37

我发的是网页发送的。

[北京]SillyPGM(1545415453) 10:53:47

没有格式，乱七八糟

W@lf(326335) 10:53:48

那不发了。

W@lf(326335) 10:54:12

这是截取的raw

[郑州] 站长苏飞<sufei.1013@163.com> 10:54:21

你这个使用类获取的内容是什么，

W@lf(326335) 10:54:41

返回html

W@lf(326335) 10:55:25

http://220.174.241.102:9808/sys/DayReport.aspx

W@lf(326335) 10:55:29

这个页面。

[重庆]Eagle(838010363) 10:55:35

未命名6.jpg

W@lf(326335) 10:56:29

他页面有个ajax

[郑州] 站长苏飞<sufei.1013@163.com> 10:57:44

恩，界面使用了Ajax，不是HttpHelper类的问题，你应该去访问Ajax获取数据的那个方法

[重庆]Eagle(838010363) 10:58:05

TimeType=day&BeginDate=2012-12-20&EndDate=2012-12-20&Item=101%2C141%2C107%2C106%2C108%2C105&Point='460100.001'%2C'460100.002'%2C'460100.003'%2C'460100.004'%2C'460100.005'&StandardName=%25u73AF%25u5883%25u7A7A%25u6C14%25u8D28%25u91CF%25u6807%25u51C6&StandardLevel=2&Judge=0&Source=0&FromHour=0&STLevel=0

[重庆]Eagle(838010363) 10:58:13

这个是提交的数据

W@lf(326335) 10:58:39

嗯。postdata就是这个了

W@lf(326335) 10:59:18

ajax也是发送请求吧。这个也可以用httphelper吧

[郑州] 站长苏飞<sufei.1013@163.com> 11:00:02

Ajax是可以用，他是你不能访问包含Ajax请求的页面，而是应该访问Ajax请求的页面哦

[重庆]Eagle(838010363) 11:00:20

发送回来的是 string

W@lf(326335) 11:00:56

都是同一个页面。

W@lf(326335) 11:01:08

ajax也是请求当前页的

[重庆]Eagle(838010363) 11:01:49

返回回来的是
<table>
........
</table>

W@lf(326335) 11:01:57

嗯。

[郑州]song、<song_xiaopeng@126.com> 11:02:13

你们说的太深奥；了

菜鸟小贝.中山(408599029) 11:02:16

ajax是请求服务器的吧..

[北京]SillyPGM(1545415453) 11:02:30

手机党，坐看你们抓包

菜鸟小贝.中山(408599029) 11:02:33

ajax是一个虚拟http socket的东西..

W@lf(326335) 11:04:51
用httphelper跟原来的包不一样。

W@lf(326335) 11:05:09
是不是哪里写错了，还是postdata里面不能包含单引号？

W@lf(326335) 11:08:33
可以了。

W@lf(326335) 11:08:39
加个ContentType = "application/x-www-form-urlencoded",就好了

W@lf(326335) 11:10:34
谢谢各位了。

[郑州] 站长苏飞<sufei.1013@163.com> 11:12:51
你这个不需要加Referer属性也是可行的，

W@lf(326335) 11:14:27
嗯，这些以前没做过，也不知道发包发注意什么东西。

.
苏飞总结：
1.其实这个问题关于在于ContentType 这个属性，表示传入请求的 MIME 内容类型的字符串
2.那当然传入不同返回的也是不同的。大家需要注册这点

站长苏飞 · 发表于 2012-12-20 11:28:39

我再补充一下最新的代码，只要执行以下代码就可以正常获取了
[code=csharp] HttpHelper http = new HttpHelper();
         HttpItem item = new HttpItem()
         {
            URL = "http://220.174.241.102:9808/sys/DayReport.aspx",//URL    必需项
            Encoding = "gbk",//编码格式（utf-8,gb2312,gbk）    可选项默认类会自动识别
            Method = "Post",//URL    可选项默认为Get

            ContentType = "application/x-www-form-urlencoded",//返回类型可选项有默认值

            Postdata = "TimeType=day&BeginDate=2012-12-20&EndDate=2012-12-20&Item=101%2C141%2C107%2C106%2C108%2C105&Point='460100.001'%2C'460100.002'%2C'460100.003'%2C'460100.004'%2C'460100.005'&StandardName=%25u73AF%25u5883%25u7A7A%25u6C14%25u8D28%25u91CF%25u6807%25u51C6&StandardLevel=2&Judge=0&Source=0&FromHour=0&STLevel=0",//Post数据    可选项GET时不需要写

         };
         //得到HTML代码
         string html = http.GetHtml(item);[/code]

难道浏览器不是吗？一样的，我们只是用浏览器的功能，页不去实现界面化
