How to use CefPostTask on browser process?

[tiplip]

Hi,

I am on CEF3 2623.1401 (to work with XP).

I create CefURLRequest on render process, after that, I want to delete cookies at runtime. So I use SendProcessMessage to browser.

I handle the message in ClientHandler::OnProcessMessageReceived

Code: Select all

    CefRefPtr<CefListValue> args = message->GetArgumentList();
    const CefString& domain = args->GetString(0);
    CefRefPtr<CefCookieManager> manager =
        CefCookieManager::GetGlobalManager(NULL);
    //manager->DeleteCookies(domain, "", NULL);

    CefPostTask(TID_IO, base::Bind(&CefCookieManager::DeleteCookies, manager, domain));

    return true;


compile error:

Code: Select all

where am I wrong?

what's the right way for my case? from render

thanks.

You need to use base::IgnoreResult(&CefCookieManager::DeleteCookies)

You need to use base::IgnoreResult(&CefCookieManager::DeleteCookies)

hi, I tried your advice as follows

Code: Select all

bool ClientHandler::OnProcessMessageReceived(
    CefRefPtr<CefBrowser> browser,
    CefProcessId source_process,
    CefRefPtr<CefProcessMessage> message) {
  CEF_REQUIRE_UI_THREAD();
...
if (message_name == kClearCookies) {
    CefRefPtr<CefListValue> args = message->GetArgumentList();
    const CefString& domain = args->GetString(0);
    CefRefPtr<CefCookieManager> manager =
        CefCookieManager::GetGlobalManager(NULL);
    //manager->DeleteCookies(domain, "", NULL);

    CefPostTask(TID_IO, base::Bind(base::IgnoreResult(&CefCookieManager::DeleteCookies), this, domain));

    return true;
  }


still the same compile error, then I define one new function

Code: Select all

void ClientHandler::ClearCookies(const CefString& domain) {
    CefRefPtr<CefCookieManager> manager =
        CefCookieManager::GetGlobalManager(NULL);
    manager->DeleteCookies(domain, "", NULL);
}

bool ClientHandler::OnProcessMessageReceived(
    CefRefPtr<CefBrowser> browser,
    CefProcessId source_process,
    CefRefPtr<CefProcessMessage> message) {
  CEF_REQUIRE_UI_THREAD();
...
if (message_name == kClearCookies) {
    CefRefPtr<CefListValue> args = message->GetArgumentList();
    const CefString& domain = args->GetString(0);
    //CefRefPtr<CefCookieManager> manager =
    //    CefCookieManager::GetGlobalManager(NULL);
    //manager->DeleteCookies(domain, "", NULL);

    //CefPostTask(TID_IO, base::Bind(base::IgnoreResult(&CefCookieManager::DeleteCookies), this, domain));
    CefPostTask(TID_IO, base::Bind(&ClientHandler::ClearCookies, this, domain));

    return true;
  }


compile successfully, I have no idea about the usage limitation on CefPostTask.

thanks.
