一起学libcef--给你的浏览器删除cookie

long long ago, 我们讨论了如给你cef设置cookie.

现在来补充一点，如果给你的浏览器删除某一cookie。

review一下设置cookie：

    std::wstring username_key = L"username";
    std::wstring username_value = L"xidada";
    std::wstring domain = L"blog.csdn.net"

    CefRefPtr<CefCookieManager> manager = CefCookieManager::GetGlobalManager();
    CefCookie cookie;
    CefString(&cookie.name).FromWString(username_key.c_str());
    CefString(&cookie.value).FromWString(username_value.c_str());
    CefString(&cookie.domain).FromWString(domain.c_str());
    CefString(&cookie.path).FromASCII("/");
    cookie.has_expires = false;

    domain = L"https://" + domain;
    CefPostTask(TID_IO, NewCefRunnableMethod(manager.get(), &CefCookieManager::SetCookie,CefString(domain.c_str()), cookie));

//创建浏览器
    CefBrowserHost::CreateBrowser(info, g_web_browser_client.get(),
        domain.c_str(), browserSettings, NULL);

现在就开始删除某一cookie：
DeleteCookies
看看函数描述：

// Delete all cookies that match the specified parameters. If both |url| and
  // values |cookie_name| are specified all host and domain cookies matching
  // both will be deleted. If only |url| is specified all host cookies (but not
  // domain cookies) irrespective of path will be deleted. If |url| is empty all
  // cookies for all hosts and domains will be deleted. Returns false if a non-
  // empty invalid URL is specified or if cookies cannot be accessed. This
  // method must be called on the IO thread.
  ///
  /*--cef(optional_param=url,optional_param=cookie_name)--*/
  virtual bool DeleteCookies(const CefString& url,
                             const CefString& cookie_name) =0;

应用：

CefPostTask(TID_IO, NewCefRunnableMethod(manager.get(), &CefCookieManager::DeleteCookies,
        CefString(domain.c_str()), CefString("username")));

以上代码就删除了为”blog.csdn.net”设置的cookie：
username = xidada
