CefRequestHandler Methods

The CefRequestHandler type exposes the following members.

Methods
  NameDescription
Protected methodDispose
Public methodEquals
Determines whether the specified object is equal to the current object.
(Inherited from Object.)
Protected methodFinalize (Overrides ObjectFinalize.)
Protected methodGetAuthCredentials
Called on the IO thread when the browser needs credentials from the user. |isProxy| indicates whether the host is a proxy server. |host| contains the hostname and |port| contains the port number. |realm| is the realm of the challenge and may be empty. |scheme| is the authentication scheme used, such as "basic" or "digest", and will be empty if the source of the request is an FTP server. Return true to continue the request and call CefAuthCallback::Continue() either in this method or at a later time when the authentication information is available. Return false to cancel the request immediately.
Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
Protected methodGetResourceHandler
Called on the IO thread before a resource is loaded. To allow the resource to load normally return NULL. To specify a handler for the resource return a CefResourceHandler object. The |request| object should not be modified in this callback.
Protected methodGetResourceResponseFilter
Called on the IO thread to optionally filter resource response content. |request| and |response| represent the request and response respectively and cannot be modified in this callback.
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Protected methodOnBeforeBrowse
Called on the UI thread before browser navigation. Return true to cancel the navigation or false to allow the navigation to proceed. The |request| object cannot be modified in this callback. CefLoadHandler::OnLoadingStateChange will be called twice in all cases. If the navigation is allowed CefLoadHandler::OnLoadStart and CefLoadHandler::OnLoadEnd will be called. If the navigation is canceled CefLoadHandler::OnLoadError will be called with an |errorCode| value of ERR_ABORTED.
Protected methodOnBeforeResourceLoad
Called on the IO thread before a resource request is loaded. The |request| object may be modified. Return RV_CONTINUE to continue the request immediately. Return RV_CONTINUE_ASYNC and call CefRequestCallback:: Continue() at a later time to continue or cancel the request asynchronously. Return RV_CANCEL to cancel the request immediately.
Protected methodOnCertificateError
Called on the UI thread to handle requests for URLs with an invalid SSL certificate. Return true and call CefRequestCallback::Continue() either in this method or at a later time to continue or cancel the request. Return false to cancel the request immediately. If CefSettings.ignore_certificate_errors is set all invalid certificates will be accepted without calling this method.
Protected methodOnOpenUrlFromTab
Called on the UI thread before OnBeforeBrowse in certain limited cases where navigating a new or different browser might be desirable. This includes user-initiated navigation that might open in a special way (e.g. links clicked via middle-click or ctrl + left-click) and certain types of cross-origin navigation initiated from the renderer process (e.g. navigating the top-level frame to/from a file URL). The |browser| and |frame| values represent the source of the navigation. The |target_disposition| value indicates where the user intended to navigate the browser based on standard Chromium behaviors (e.g. current tab, new tab, etc). The |user_gesture| value will be true if the browser navigated via explicit user gesture (e.g. clicking a link) or false if it navigated automatically (e.g. via the DomContentLoaded event). Return true to cancel the navigation or false to allow the navigation to proceed in the source browser's top-level frame.
Protected methodOnPluginCrashed
Called on the browser process UI thread when a plugin has crashed. |plugin_path| is the path of the plugin that crashed.
Protected methodOnProtocolExecution
Called on the UI thread to handle requests for URLs with an unknown protocol component. Set |allow_os_execution| to true to attempt execution via the registered OS protocol handler, if any. SECURITY WARNING: YOU SHOULD USE THIS METHOD TO ENFORCE RESTRICTIONS BASED ON SCHEME, HOST OR OTHER URL ANALYSIS BEFORE ALLOWING OS EXECUTION.
Protected methodOnQuotaRequest
Called on the IO thread when JavaScript requests a specific storage quota size via the webkitStorageInfo.requestQuota function. |origin_url| is the origin of the page making the request. |new_size| is the requested quota size in bytes. Return true to continue the request and call CefRequestCallback::Continue() either in this method or at a later time to grant or deny the request. Return false to cancel the request immediately.
Protected methodOnRenderProcessTerminated
Called on the browser process UI thread when the render process terminates unexpectedly. |status| indicates how the process terminated.
Protected methodOnRenderViewReady
Called on the browser process UI thread when the render view associated with |browser| is ready to receive/handle IPC messages in the render process.
Protected methodOnResourceLoadComplete
Called on the IO thread when a resource load has completed. |request| and |response| represent the request and response respectively and cannot be modified in this callback. |status| indicates the load completion status. |received_content_length| is the number of response bytes actually read.
Protected methodOnResourceRedirect
Called on the IO thread when a resource load is redirected. The |request| parameter will contain the old URL and other request-related information. The |new_url| parameter will contain the new URL and can be changed if desired. The |request| object cannot be modified in this callback.
Protected methodOnResourceResponse
Called on the IO thread when a resource response is received. To allow the resource to load normally return false. To redirect or retry the resource modify |request| (url, headers or post body) and return true. The |response| object cannot be modified in this callback.
Public methodToString
Returns a string that represents the current object.
(Inherited from Object.)
