首先从cef_cookie.h 源码中看到CefCookieManager 这个类：
// Visit all cookies on the IO thread. The returned cookies are ordered by
// longest path, then by earliest creation date. Returns false if cookies
// cannot be accessed.
///
/*--cef()--*/
virtual bool VisitAllCookies(CefRefPtr<CefCookieVisitor> visitor) =0;
///
// Visit a subset of cookies on the IO thread. The results are filtered by the
// given url scheme, host, domain and path. If |includeHttpOnly| is true
// HTTP-only cookies will also be included in the results. The returned
// cookies are ordered by longest path, then by earliest creation date.
// Returns false if cookies cannot be accessed.
///
/*--cef()--*/
virtual bool VisitUrlCookies(const CefString& url,
bool includeHttpOnly,
CefRefPtr<CefCookieVisitor> visitor) =0;
1 class CefCookieVisitor : public virtual CefBase { 2 public: 3 /// 4 // Method that will be called once for each cookie. |count| is the 0-based 5 // index for the current cookie. |total| is the total number of cookies. 6 // Set |deleteCookie| to true to delete the cookie currently being visited. 7 // Return false to stop visiting cookies. This method may never be called if 8 // no cookies are found. 9 /// 10 /*--cef()--*/ 11 virtual bool Visit(const CefCookie& cookie, int count, int total, 12 bool& deleteCookie) =0; 13 };
可以通过VisitAllCookies获取所有cookies；VisitUrlCookies获取域名下的所有cookies。
看到VisitUrlCookies的参数是CefCookieVisitor；所以实现一个类用于回调读取cookies；
class CCookieVisitor : public CefCookieVisitor { public: CCookieVisitor() {}; ~CCookieVisitor() {}; bool Visit(const CefCookie& cookie, int count, int total, bool& deleteCookie); //这是一个宏 //所有的框架类从CefBase继承，实例指针由CefRefPtr管理，CefRefPtr通过调用AddRef()和Release()方法自动管理引用计数。 IMPLEMENT_REFCOUNTING(CookieVisitor); };
//作为类的成员变量
CefRefPtr<CCookieVisitor> m_CookieVisitor; m_CookieVisitor(new CCookieVisitor());
//以下代码执行 即回调Visit
CefRefPtr<CefCookieManager> cefCookieManager = CefCookieManager::GetGlobalManager(nullptr);
if (cefCookieManager)
{
cefCookieManager->VisitUrlCookies(url ,true , m_visitor);
}
回调进行读取，count为当前cookie total为总数。具体看CefCookieVisitor的注释，接下来便可以Visit读取到数据
1 bool CookieVisitor::Visit(const CefCookie & cookie, int count, int total, bool & deleteCookie) 2 { 3 if (count == total) 4 { 5 return false; 6 } 7 if (cookie.name.str && cookie.value.str) 8 { 9 string strName = cookie.name.str; 10 string strValue = cookie.value.str; 11 } 12 return true; 13 }
结束！
