java.lang.Object

org.cef.handler.CefResourceHandlerAdapter

所有已实现的接口:

CefResourceHandler

public abstract class CefResourceHandlerAdapter
extends java.lang.Object
implements CefResourceHandler

An abstract adapter class for receiving resource requests. The methods in this class are empty. This class exists as convenience for creating handler objects. (用于接收资源请求的抽象适配器类。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。)

CefResourceHandlerAdapter

public CefResourceHandlerAdapter()

方法详细资料

cancel

public void cancel()

从接口复制的说明: CefResourceHandler

Request processing has been canceled. (请求处理已被取消。)

指定者:

cancel 在接口中 CefResourceHandler

getResponseHeaders

public void getResponseHeaders(CefResponse response,
                               IntRef responseLength,
                               StringRef redirectUrl)

从接口复制的说明: CefResourceHandler

Retrieve response header information. If the response length is not known set |responseLength| to -1 and readResponse() will be called until it returns false. If the response length is known set |responseLength| to a positive value and readResponse() will be called until it returns false or the specified number of bytes have been read. Use the |response| object to set the mime type, http status code and other optional header values. (检索响应头信息。如果响应长度未知，则设置| responseLength |。到-1，readResponse（）将被调用，直到返回false。如果已知响应长度，则设置| responseLength |。设置为正值，将调用readResponse（）直到返回false或已读取指定的字节数。使用|响应|对象，用于设置mime类型，http状态代码和其他可选标头值。)

指定者:

getResponseHeaders 在接口中 CefResourceHandler

参数:

response - The request response that should be returned. Instance only valid within the scope of this method. (-应该返回的请求响应。实例仅在此方法的范围内有效。)

responseLength - Optionally set the response length if known. (-（可选）设置响应长度（如果已知）。)

redirectUrl - Optionally redirect the request to a new URL. (-（可选）将请求重定向到新的URL。)

processRequest

public boolean processRequest(CefRequest request,
                              CefCallback callback)

从接口复制的说明: CefResourceHandler

Begin processing the request. (开始处理请求。)

指定者:

processRequest 在接口中 CefResourceHandler

参数:

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。)

callback - Callback to continue or cancel the request. (-回调以继续或取消请求。)

返回:

True to handle the request and call CefCallback.Continue() once the response header information is available. (为true时处理请求，并在响应头信息可用时调用CefCallback.Continue（）。)

readResponse

public boolean readResponse(byte[] dataOut,
                            int bytesToRead,
                            IntRef bytesRead,
                            CefCallback callback)

从接口复制的说明: CefResourceHandler

Read response data. If data is available immediately copy up to |bytesToRead| bytes into |dataOut|, set |bytesRead| to the number of bytes copied, and return true. To read the data at a later time set |bytesRead| to 0, return true and call CefCallback.Continue() when the data is available. To indicate response completion return false. (读取响应数据。如果有数据，请立即复制到| bytesToRead |。个字节到| dataOut |中，设置| bytesRead |到复制的字节数，然后返回true。要在以后读取数据，请设置| bytesRead |。设为0，则返回true，并在数据可用时调用CefCallback.Continue（）。要指示响应完成，请返回false。)

指定者:

readResponse 在接口中 CefResourceHandler

参数:

dataOut - Write data to this buffer. (-将数据写入此缓冲区。)

bytesToRead - Size of the buffer. (-缓冲区的大小。)

bytesRead - Number of bytes written to the buffer. (-写入缓冲区的字节数。)

callback - Callback to execute if data will be available asynchronously. (-如果数据异步可用，则执行回调。)

返回:

True if more data is or will be available. (如果有或将有更多数据可用，则为true。)
