有关于微软的IWebBrowser2::Navigate2/Navigate方法

我曾经的要求很简单，只是要在我内置BROWSER发请求在在头里加入COOKIE值，

但试来试去都不成，但有趣的是的，我在头里加入其它东西是可行的，如：

User-Agent: NetMe

请求时加上了，可如果是：Cookie:aa=bb，就加不上，找了好多地方，想找到答案，

最后在GOOGLE论坛里有人做了“解释”：

它问了微软的人，用该控件无法加COOKIE，FT！！！

http://groups.google.com/group/microsoft.public.windows.inetexplorer.ie5.programming.components.webbrowser_ctl/browse_thread/thread/72f156bc95dfbe34/f3078180122c5529%23f3078180122c5529?sa=X&oi=groupsr&start=2&num=3

code:

CString str="";

//this->m_editurl.GetWindowText(str);

//this->m_editurl.GetWindowText("http://localhost:8080/angel");

VARIANT varProject;
const char *pszMsg = "http://127.0.0.1:8080";
//const char *pszMsg1 = "User-Agent: NetAnts";
const char *pszMsg1 = "Cookie: JSESSIONID=0112BF7D0C9FD914716EE17AD2AD7913";

VARIANT p1;
VARIANT p2;
VARIANT p3;
VariantInit(&varProject);
VariantInit(&p1);
VariantInit(&p2);
VariantInit(&p3);

p2.vt = VT_BSTR;
p2.bstrVal = SysAllocString(A2BSTR(pszMsg));//_bstr_t("http://127.0.0.1:8080/angel");

CString *s = new CString(p2.bstrVal);
//AfxMessageBox((LPCTSTR)s);

varProject.vt = VT_BSTR;
p1.vt = VT_BSTR;
p1.bstrVal= SysAllocString(A2BSTR(pszMsg));

//CComBSTR bstrXml ;
//bstrXml.Attach(SysAllocStringLen(p,47));

//varProject.bstrVal = bstrXml;
varProject.bstrVal = SysAllocString(A2BSTR(pszMsg1));

this->m_ie.Navigate2(&p2,0,0,0,&varProject);

I'd like to add cookies when I call IWebBrowser2::Navigate.
For example:
SHDocVw::IWebBrowser2Ptr spBrowser;//already created
_variant_t vtEmpty;
_bstr_t bstrURL;// already set to valid URL;
_variant_t vCookie(_bstr_t("Cookie: foo = bar"));

spBrowser->Navigate
(
bstrURL,
&vtEmpty/*flags*/,
&vtEmpty/*frame*/,
&vtEmpty/*post data*/,
&vCookie/*headers*/
);

The cookie I set does not appear on the server. I assume that the
syntax I'm passing to the 'headers' argument of Navigate is incorrect,
but I see no documentation about exactly how to set 'headers'.

When I monitor the IE event BeforeNavigate2, it shows the 'header'
argument, which includes some garbled version of the characters I
put in vCookie.

Any help will be appreciated.

Thanks,

Paul Bradford

See RFC 2109. The óookie header is rather complex:

cookie = "Cookie:" cookie-version
1*((";" | ",") cookie-value)
cookie-value = NAME "=" VALUE [";" path] [";" domain]
cookie-version = "$Version" "=" value
NAME = attr
VALUE = value
path = "$Path" "=" value
domain = "$Domain" "=" value

For example:

Cookie: $Version="1"; Customer="WILE_E_COYOTE"; $Path="/acme"

$Version parameter is mandatory-- With best wishes, Igor Tandetnik

I set a breakpoint in BeforeNavigate2 and look at Headers. It contains
some of the characters from the 'headers' parameter in my call to
IWebBrowser::Navigate, but it's all garbled. There is something
about my 'headers' parameter to Navigate that is not correct, but
I don't know what.

What exactly should the 'headers' argument to IWebBrowser2::Navigate
look like?

In case anybody is interested, I went through Microsoft support
to find out more about this. Their answer: what I want to do is
not supported. The 'headers' argument to Navigate/Navigate2
CANNOT be used to set cookies. There is no way to set cookies
for an IWebBrowser2 object.

I consider this a bug, but what I think is unlikely to change anything :)

We solved my problem in a completely different way.
