所有已实现的接口:

CefRequestContextHandler

public abstract class CefRequestContextHandlerAdapter
extends java.lang.Object
implements CefRequestContextHandler

An abstract adapter class for receiving browser request context events. The methods in this class are empty. This class exists as convenience for creating handler objects. (用于接收浏览器请求上下文事件的抽象适配器类。此类中的方法为空。此类的存在是为了方便创建处理程序对象。)

getResourceRequestHandler

public CefResourceRequestHandler getResourceRequestHandler(CefBrowser browser,
                                                           CefFrame frame,

                                                           boolean isNavigation,

                                                           BoolRef disableDefaultHandling)

从接口复制的说明: CefRequestContextHandler

Called on the IO thread before a resource request is initiated. The |browser| and |frame| values represent the source of the request. This method will not be called if the client associated with |browser| returns a non-null value from CefRequestHandler.getResourceRequestHandler for the same request (identified by CefRequest.getIdentifier). (在启动资源请求之前在IO线程上调用。 |浏览器|和| frame |值表示请求的来源。如果与| browser |相关联的客户端将不会调用此方法。对于相同的请求（由CefRequest.getIdentifier标识）从CefRequestHandler.getResourceRequestHandler返回一个非空值。)

指定者:

getResourceRequestHandler 在接口中 CefRequestContextHandler

参数:

browser - The corresponding browser. (-相应的浏览器。)

frame - The frame generating the event. Instance only valid within the scope of this method. (-生成事件的框架。实例仅在此方法的范围内有效。)

request - The request itself. Cannot be modified in this callback. Instance only valid within the scope of this method. (-请求本身。无法在此回调中修改。实例仅在此方法的范围内有效。)

isNavigation - True if the resource request is a navigation. (-如果资源请求是导航，则为true。)

isDownload - True if the resource request is a download. (-如果资源请求是下载，则为true。)

requestInitiator - The origin (scheme + domain) of the page that initiated the request. (-发起请求的页面的来源（方案+域）。)

disableDefaultHandling - Set to true to disable default handling of the request, in which case it will need to be handled via CefResourceRequestHandler.getResourceHandler or it will be canceled. (-设置为true可禁用请求的默认处理，在这种情况下，需要通过CefResourceRequestHandler.getResourceHandler进行处理，否则将被取消。)

返回:

A CefResourceRequestHandler instance or null. (CefResourceRequestHandler实例，或者为null。)

onBeforePluginLoad

public boolean onBeforePluginLoad(java.lang.String mime_type,
                                  java.lang.String plugin_url,
                                  boolean is_main_frame,
                                  java.lang.String top_origin_url,
                                  CefWebPluginInfo plugin_info)

从接口复制的说明: CefRequestContextHandler

Called on multiple browser process threads before a plugin instance is loaded. (在加载插件实例之前，在多个浏览器进程线程上调用。)

指定者:

onBeforePluginLoad 在接口中 CefRequestContextHandler

参数:

mime_type - is the mime type of the plugin that will be loaded. (-是将要加载的插件的mime类型。)

plugin_url - is the content URL that the plugin will load and may be empty. (-是插件将加载的内容URL，可能为空。)

is_main_frame - will be true if the plugin is being loaded in the main (top-level) frame. (-如果插件在主（顶层）框架中加载，则为true。)

top_origin_url - is the URL for the top-level frame that contains the plugin when loading a specific plugin instance or empty when building the initial list of enabled plugins for 'navigator.plugins' JavaScript state. (-是在加载特定插件实例时包含插件的顶级框架的URL，或者在为“ navigator.plugins” JavaScript状态构建启用的插件的初始列表时为空白。)

plugin_info - includes additional information about the plugin that will be loaded. |plugin_policy| is the recommended policy. (-包括有关将要加载的插件的其他信息。 | plugin_policy |是推荐的政策。)

返回:

true to block loading of the plugin. (true表示阻止插件加载。)
