HttpWebRequest的的CookieContainer [英] httpwebrequest Cookiecontainer
本文介绍了HttpWebRequest的的CookieContainer的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我如何处理cookie比/其他路径。 一个HttpWebRequest对象返回这些标头：
HTTP / 1.1 302临时移动
传输编码：分块
日期：周三2009 GMT 13时22分53秒6月10日
内容类型：text / html的;字符集= UTF-8
到期日：周三2009 GMT十三时22分53秒6月10日
的Cache-Control：no-cache的，必重新验证，最大年龄= 0
服务器：nginx / 0.7.41
的X已启动方式：PHP / 5.2.9
最后一次修改：周三2009年6月10日13时22分52秒格林尼治标准时间
杂注：无缓存
设置Cookie：COOKIE1 = C1;路径= /;域= site.com
设置Cookie：COOKIE2 = C2; PATH = /内容;域= site.com;仅Http
设置Cookie：cookie3 = C3; PATH = /管理;域= site.com;仅Http
设置Cookie：cookie4 = 4;路径= /;域= site.com;仅Http
地点：http://site.com/admin/
途经：1.1 MVO-的NetCache-02（的NetCache的NetApp / 6.0.7）
迭代通过Cookie集合只containsthe饼干的/的路径。 所以的CookieContainer只有COOKIE1和cookie4在里面。
为什么其他地方没有被收集的？ 如何访问饼干比/其他路径？我可以收集他们都 在一个容器？</ P>
感谢
解决方案
由于频率这个问题出现在网上，我怀疑的问题是，.NET库code不支持多的Set-Cookie头（要么所有的时间或仅在某些情况下）。无论如何，这是pretty的容易解决。只需直接在Set-Cookie头中提取的cookies。下面是一些code（最初是从code复制连接到<一个href="http://www.velocityreviews.com/forums/t120691-cookiecontainer-getcookies-fails-on-multiple-setcookies.html">this螺纹），它展示了如何直接在Set-Cookie头中提取的cookies。
公共静态CookieCollection GetAllCookiesFromHeader（字符串strHeader，串strHost）
{
ArrayList的人=新的ArrayList（）;
CookieCollection CC =新CookieCollection（）;
如果（strHeader！=的String.Empty）
{
人= ConvertCookieHeaderToArrayList（strHeader）;
CC = ConvertCookieArraysToCookieCollection（人，strHost）;
}
返回CC;
}
私有静态的ArrayList ConvertCookieHeaderToArrayList（字符串strCookHeader）
{
strCookHeader = strCookHeader.Replace（\ r，）;
strCookHeader = strCookHeader.Replace（\ N，）;
串[] strCookTemp = strCookHeader.Split（，）;
ArrayList的人=新的ArrayList（）;
INT I = 0;
INT N = strCookTemp.Length;
而（ⅰn种）
{
如果（strCookTemp [I] .IndexOf（期满=，StringComparison.OrdinalIgnoreCase）大于0）
{
al.Add（strCookTemp [I] +，+ strCookTemp [I + 1]）;
I = I + 1;
}
其他
{
al.Add（strCookTemp [I]）;
}
I = I + 1;
}
返回人;
}
私有静态CookieCollection ConvertCookieArraysToCookieCollection（ArrayList的人，串strHost）
{
CookieCollection CC =新CookieCollection（）;
INT alcount = al.Count;
串strEachCook;
字符串[] strEachCookParts;
的for（int i = 0; I＆LT; alcount;我++）
{
strEachCook =人[我]的ToString（）;
strEachCookParts = strEachCook.Split（';'）;
INT intEachCookPartsCount = strEachCookParts.Length;
字符串strCNameAndCValue =的String.Empty;
字符串strPNameAndPValue =的String.Empty;
字符串strDNameAndDValue =的String.Empty;
字符串[] NameValuePairTemp;
曲奇cookTemp =新的Cookie（）;
对于（INT J = 0; J＆LT; intEachCookPartsCount; J ++）
{
如果（j == 0）
{
strCNameAndCValue = strEachCookParts [J]。
如果（strCNameAndCValue！=的String.Empty）
{
INT firstEqual = strCNameAndCValue.IndexOf（=）;
串的firstName = strCNameAndCValue.Substring（0，firstEqual）;
串allValue = strCNameAndCValue.Substring（firstEqual + 1，strCNameAndCValue.Length - （firstEqual + 1））;
cookTemp.Name =名字;
cookTemp.Value = allValue;
}
继续;
}
如果（strEachCookParts [J] .IndexOf（路径，StringComparison.OrdinalIgnoreCase）＆GT; = 0）
{
strPNameAndPValue = strEachCookParts [J]。
如果（strPNameAndPValue！=的String.Empty）
{
NameValuePairTemp = strPNameAndPValue.Split（'='）;
如果（NameValuePairTemp [1]！=的String.Empty）
{
cookTemp.Path = NameValuePairTemp [1];
}
其他
{
cookTemp.Path =/;
}
}
继续;
}
如果（strEachCookParts [J] .IndexOf（域，StringComparison.OrdinalIgnoreCase）＆GT; = 0）
{
strPNameAndPValue = strEachCookParts [J]。
如果（strPNameAndPValue！=的String.Empty）
{
NameValuePairTemp = strPNameAndPValue.Split（'='）;
如果（NameValuePairTemp [1]！=的String.Empty）
{
cookTemp.Domain = NameValuePairTemp [1];
}
其他
{
cookTemp.Domain = strHost;
}
}
继续;
}
}
如果（cookTemp.Path ==的String.Empty）
{
cookTemp.Path =/;
}
如果（cookTemp.Domain ==的String.Empty）
{
cookTemp.Domain = strHost;
}
cc.Add（cookTemp）;
}
返回CC;
}
How do I handle cookies with paths other than "/". An HttpWebRequest object returns these headers:
HTTP/1.1 302 Moved Temporarily
Transfer-Encoding: chunked
Date: Wed, 10 Jun 2009 13:22:53 GMT

Pragma: no-cache
Set-Cookie: cookie1=c1; path=/; domain=site.com
Set-Cookie: cookie2=c2; path=/content; domain=site.com; httponly
Set-Cookie: cookie3=c3; path=/admin; domain=site.com; httponly
Set-Cookie: cookie4=c4; path=/; domain=site.com; httponly
Location: http://site.com/admin/
Via: 1.1 mvo-netcache-02 (NetCache NetApp/6.0.7)
Iterating through a cookie collection only containsthe cookies with a path of "/". So the cookiecontainer only has cookie1 and cookie4 in it.
Why are the rest not being collected? How do I access the cookies with paths other than "/"? Can I gather them all in one container?
Thanks
解决方案
Given how frequently this issue comes up online, I suspect the problem is that the .NET library code doesn't support multiple Set-Cookie headers (either all the time or only under some circumstances). Regardless, it's pretty easy to work around. Just extract the cookies directly from the Set-Cookie headers. Here's some code (originally copied from code attached to this thread) which shows how to extract cookies directly from the Set-Cookie header.
public static CookieCollection GetAllCookiesFromHeader(string strHeader, string strHost)
{
ArrayList al = new ArrayList();
CookieCollection cc = new CookieCollection();
if (strHeader != string.Empty)
{
al = ConvertCookieHeaderToArrayList(strHeader);
cc = ConvertCookieArraysToCookieCollection(al, strHost);
}
return cc;
}
private static ArrayList ConvertCookieHeaderToArrayList(string strCookHeader)
{
strCookHeader = strCookHeader.Replace("\r", "");
strCookHeader = strCookHeader.Replace("\n", "");
string[] strCookTemp = strCookHeader.Split(',');
ArrayList al = new ArrayList();
int i = 0;
int n = strCookTemp.Length;
while (i < n)
{
if (strCookTemp[i].IndexOf("expires=", StringComparison.OrdinalIgnoreCase) > 0)
{
al.Add(strCookTemp[i] + "," + strCookTemp[i + 1]);
i = i + 1;
}
else
{
al.Add(strCookTemp[i]);
}
i = i + 1;
}
return al;
}
private static CookieCollection ConvertCookieArraysToCookieCollection(ArrayList al, string strHost)
{
CookieCollection cc = new CookieCollection();
int alcount = al.Count;
string strEachCook;
string[] strEachCookParts;
for (int i = 0; i < alcount; i++)
{
strEachCook = al[i].ToString();
strEachCookParts = strEachCook.Split(';');
int intEachCookPartsCount = strEachCookParts.Length;
string strCNameAndCValue = string.Empty;
string strPNameAndPValue = string.Empty;
string strDNameAndDValue = string.Empty;
string[] NameValuePairTemp;
Cookie cookTemp = new Cookie();
for (int j = 0; j < intEachCookPartsCount; j++)
{
if (j == 0)
{
strCNameAndCValue = strEachCookParts[j];
if (strCNameAndCValue != string.Empty)
{
int firstEqual = strCNameAndCValue.IndexOf("=");
string firstName = strCNameAndCValue.Substring(0, firstEqual);
string allValue = strCNameAndCValue.Substring(firstEqual + 1, strCNameAndCValue.Length - (firstEqual + 1));
cookTemp.Name = firstName;
cookTemp.Value = allValue;
}
continue;
}
if (strEachCookParts[j].IndexOf("path", StringComparison.OrdinalIgnoreCase) >= 0)
{
strPNameAndPValue = strEachCookParts[j];
if (strPNameAndPValue != string.Empty)
{
NameValuePairTemp = strPNameAndPValue.Split('=');
if (NameValuePairTemp[1] != string.Empty)
{
cookTemp.Path = NameValuePairTemp[1];
}
else
{
cookTemp.Path = "/";
}
}
continue;
}
if (strEachCookParts[j].IndexOf("domain", StringComparison.OrdinalIgnoreCase) >= 0)
{
strPNameAndPValue = strEachCookParts[j];
if (strPNameAndPValue != string.Empty)
{
NameValuePairTemp = strPNameAndPValue.Split('=');
if (NameValuePairTemp[1] != string.Empty)
{
cookTemp.Domain = NameValuePairTemp[1];
}
else
{
cookTemp.Domain = strHost;
}
}
continue;
}
}
if (cookTemp.Path == string.Empty)
{
cookTemp.Path = "/";
}
if (cookTemp.Domain == string.Empty)
{
cookTemp.Domain = strHost;
}
cc.Add(cookTemp);
}
return cc;
}
