javacef获取cookie,CEF3获取Cookie例子CefCookieManagerC++

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 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 visitor) =0;

1 class CefCOOKIEVisitor : public virtualCefBase {2 public:3 ///4 //Method that will be called once for each COOKIE. |count| is the 0-based5 //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 if8 //no COOKIEs are found.

9 ///10 /*--cef()--*/

11 virtual bool Visit(const CefCOOKIE& COOKIE, int count, inttotal,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 : publicCefCOOKIEVisitor

{public:

CCOOKIEVisitor() {};~CCOOKIEVisitor() {};bool Visit(const CefCOOKIE& COOKIE, int count, inttotal,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

CefRefPtrm_COOKIEVisitor;

m_COOKIEVisitor(new CCOOKIEVisitor());

//以下代码执行 即回调Visit

CefRefPtr 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！
