[C#HttpHelper]类DotNet4.0正式版教程与升级报告

有个问题想说一下：
1、一般用完的HttpWebRequest要Abort()或者要把 Response.Close()，httphelper里面没 ...

1.你这点说的很对，只不过我里面写的是用的，只是语法不一样
[code=csharp] using (response = (HttpWebResponse)request.GetResponse())[/code]
看到这里你就明白了，如果不清楚什么是using 语句可以百度一下
2.httpitem.cookie和httpitem.cookiecollection不是只有一个生效，而是看你使用那个，那个就有效
这个取决于服务端。
3.你再看下类面的这句 if (response.Cookies != null) result.CookieCollection = response.Cookies;
这和你用什么容器接收没有关系，所以完全可以排除你说的情况，这和使用cookiecontainer还是CookieCollection接收没有任何关系的。
肯定是其他地方影响的。
4. if (item.ProtocolVersion != null) request.ProtocolVersion = item.ProtocolVersion;你看看代码，如果你不设置是不会赋值，也就是默认的，所以这里你说的情况不存在，
非常 建议您再好好看下我的源码。同时对你提出的建议表示感谢

首先感谢您的回复
第一个问题抱歉，是我看源码不仔细，后面几个问题我把代码敲出来验证一下，
再次麻烦您很抱歉，我很喜欢httphelper类，我只想解决心中的疑惑，也希望httphelper越做越好，所以麻烦您看一下我的代码：
首先看这个代码

1. private void button1_Click(object sender, EventArgs e)
   
2. {
   
3. HttpItem loginItem= new HttpItem();
   
4. loginItem.UserAgent = "Mozilla/5.0 (iPhone; U; CPU iPhone OS 3_0 like Mac OS X; en-us) AppleWebKit/528.18 (KHTML, like Gecko) Version/4.0 Mobile/7A341 Safari/528.16";
   
5. loginItem.Method = "post";
   
6. loginItem.URL = "https://account.xiaomi.com/pass/serviceLoginAuth";
   
7. loginItem.Postdata = "user=axiaomi007%40163.com&pwd=xiaomi8513&callback=http%3A%2F%2Fm.xiaomi.com%2Fmshopapi%2Fv1%2Fauthorize%2Fsso_callback%3Ffollowup%3Dhttp%253A%252F%252Fm.xiaomi.com%252F%2523ac%253Daccount%2526op%253Dindex%26sign%3DNGNmM2VmZDlkZTQ5MGMzMmNjN2Y2MjBmNjc0MGNiMWQxZjg0MzAxNQ%2C%2C&sid=eshopm&display=mobile";
   
8. loginItem.ContentType = "application/x-www-form-urlencoded";
   
9. loginItem.Allowautoredirect = true;
   
10. 
    
11. HttpHelper httphelper = new HttpHelper();
    
12. HttpResult result = httphelper.GetHtml(loginItem);
    
13. 
    
14. textBox1.Text = result.Html;
    
15. }

复制代码

执行后textBox1的内容为：“基础连接已经关闭: 接收时发生错误。”；
然后在上面加上
loginItem.SecurityProtocolType = SecurityProtocolType.Ssl3;
之后就能正常接收了，
说明SecurityProtocolType的默认值是不行的，所以建议设置默认值

再说cookie问题

1. private void button1_Click(object sender, EventArgs e)
   
2. {
   
3.   HttpItem loginItem= new HttpItem();
   
4.   loginItem.UserAgent = "Mozilla/5.0 (iPhone; U; CPU iPhone OS 3_0 like Mac OS X; en-us) AppleWebKit/528.18 (KHTML, like Gecko) Version/4.0 Mobile/7A341 Safari/528.16";
   
5.   loginItem.Method = "post";
   
6.   loginItem.URL = "https://account.xiaomi.com/pass/serviceLoginAuth";
   
7.   loginItem.Postdata = "user=axiaomi007%40163.com&pwd=xiaomi8513&callback=http%3A%2F%2Fm.xiaomi.com%2Fmshopapi%2Fv1%2Fauthorize%2Fsso_callback%3Ffollowup%3Dhttp%253A%252F%252Fm.xiaomi.com%252F%2523ac%253Daccount%2526op%253Dindex%26sign%3DNGNmM2VmZDlkZTQ5MGMzMmNjN2Y2MjBmNjc0MGNiMWQxZjg0MzAxNQ%2C%2C&sid=eshopm&display=mobile";
   
8.   loginItem.ContentType = "application/x-www-form-urlencoded";
   
9.   loginItem.Allowautoredirect = true;
   
10.   loginItem.SecurityProtocolType = SecurityProtocolType.Ssl3;
    
11. 
    
12.   HttpHelper httphelper = new HttpHelper();
    
13.   HttpResult result = httphelper.GetHtml(loginItem);
    
14. 
    
15.   textBox1.Text = result.Html;
    
16. 
    
17.   if (result.CookieCollection != null)
    
18.     MessageBox.Show(result.CookieCollection.Count.ToString());
    
19.   else MessageBox.Show("空");
    
20. }

复制代码

执行结果messagebox显示0
抓包数据如下：
首先是post请求：
POST /pass/serviceLoginAuth HTTP/1.1
Accept: text/html, application/xhtml+xml, */*
Content-Type: application/x-www-form-urlencoded
User-Agent: Mozilla/5.0 (iPhone; U; CPU iPhone OS 3_0 like Mac OS X; en-us) AppleWebKit/528.18 (KHTML, like Gecko) Version/4.0 Mobile/7A341 Safari/528.16

响应是一个跳转，有多个setcookie：

然后是自动跳转的请求，自动跳转的请求理应带上上面的cookie信息，但是却没有：
GET /mshopapi/v1/authorize/sso_callback?followup=http%3A%2F%2Fm.xiaomi.com%2F%23ac%3Daccount%26op%3Dindex&sign=NGNmM2VmZDlkZTQ5MGMzMmNjN2Y2MjBmNjc0MGNiMWQxZjg0MzAxNQ,,&auth=GOmpdbc1mTbhiuq0A8Mb3BtpwuuEUZli%2FF%2F0eZuQsW8lOGfVG8p6bfB4b%2B1tS9YAvWQsuHbzuUUpck86pRKanqhZ%2BvVSzn73%2FkR20xkeVCWX42d5H8EuREntWvS4tuaSlu1%2Bbxxi07hnpQ70KkHki99ur%2FJd3FUxyM8GXM4apks%3D HTTP/1.1

Host: m.xiaomi.com
Connection: Keep-Alive

然后是对应的响应，可以看到由于没有携带cookie而跳回首页：
HTTP/1.1 302 Moved Temporarily

Content-Type: text/html

Cache-Control: must-revalidate,no-cache

0

跳转到首页的抓包就不贴上来了。。。
然后接着说代码：
把自动跳转关闭测试
loginItem.Allowautoredirect = false;
相当于上面的抓包信息只执行了第一步请求和响应，响应里面有set_cookie;
然后MessageBox.Show(result.CookieCollection.Count.ToString());显示依然为0，说明响应的cookie就没有添加到cookiecollection里面

1.你这点说的很对，只不过我里面写的是用的，只是语法不一样

看到这里你就明白了，如果不清楚什么是us ...

然后说cookie和cookiecollection只有一个生效的问题
在loginItem.CookieCollection添加一个名为test1的cookie测试

1. private void button1_Click(object sender, EventArgs e)
   
2. {
   
3.   HttpItem loginItem= new HttpItem();
   
4.   loginItem.UserAgent = "Mozilla/5.0 (iPhone; U; CPU iPhone OS 3_0 like Mac OS X; en-us) AppleWebKit/528.18 (KHTML, like Gecko) Version/4.0 Mobile/7A341 Safari/528.16";

8.   loginItem.ContentType = "application/x-www-form-urlencoded";
   
9.   loginItem.Allowautoredirect = false;
   
10.   loginItem.SecurityProtocolType = SecurityProtocolType.Ssl3;
    
11. 
    
12.   loginItem.CookieCollection = new CookieCollection();//添加test1 的cookie
    
13.   loginItem.CookieCollection.Add(new Cookie("test1", "test1", "/", ".xiaomi.com"));
    
14. 
    
15.   HttpHelper httphelper = new HttpHelper();
    
16.   HttpResult result = httphelper.GetHtml(loginItem);
    
17. }

在loginItem.Cookie添加一个名为test2的cookie测试

然后说cookie和cookiecollection只有一个生效的问题
在loginItem.CookieCollection添加一个名为test1的c ...

1.默认值的问题，我建议还是不要添加的好。保存原生。呵呵。这个毕竟有待考量
2.你说的Cookie，从理论上讲。NEt返回的就是一个CookieCollection集合，你修改成cookiecontainer
无非也是将他转化一下，不可能影响他的传输的，
这点我也做过测试。不能光考虑Net环境。在有些情况下，还是比较复杂的。
在没有得到精确的结论之前我还需要先保持现在的情况，毕竟现在是原生的，没有进行任何处理，
关于这点，我有时间会有研究一下，
如果你有比较精确的结论也欢迎提出来，可以发个帖子出来。
或者加我的Qq讨论一下。
再次对你提出的建议表示感谢
这个东西官方并没有给出明显的说明，
不过建议还是使用StrCookie，

zizhu123

if (!string.IsNullOrWhiteSpace(item.Host))
            {
                request.Host = item.Host;
            }
这句代码在.net 3.5 当中该怎么写啊
