接口 CefResourceHandler

所有超级接口:

CefNative

所有已知实现类:

CefResourceHandlerAdapter

public interface CefResourceHandler
extends CefNative

Implement this interface to handle custom resource requests. The methods of this class will always be called on the IO thread.

实现此接口以处理自定义资源请求。始终在IO线程上调用此类的方法。

方法概要

限定符和类型	方法和说明
void	cancel() Request processing has been canceled. 请求处理已被取消。
boolean	canGetCookie(CefCookie cookie) Return true if the specified cookie can be sent with the request or false otherwise. 如果指定的cookie可以随请求一起发送，则返回true，否则返回false。
boolean	canSetCookie(CefCookie cookie) Return true if the specified cookie returned with the response can be set or false otherwise. 如果可以设置随响应返回的指定cookie，则返回true，否则返回false。
void	getResponseHeaders(CefResponse response, IntRef response_length, StringRef redirectUrl) Retrieve response header information. 检索响应头信息。
boolean	processRequest(CefRequest request, CefCallback callback) Begin processing the request. 开始处理请求。
boolean	readResponse(byte[] data_out, int bytes_to_read, IntRef bytes_read, CefCallback callback) Read response data. 读取响应数据。

方法详细资料

cancel

void cancel()

Request processing has been canceled.

请求处理已被取消。

canGetCookie

boolean canGetCookie(CefCookie cookie)

Return true if the specified cookie can be sent with the request or false otherwise. If false is returned for any cookie then no cookies will be sent with the request.

如果指定的cookie可以随请求一起发送，则返回true，否则返回false。如果任何cookie返回false，则不会随请求一起发送cookie。

canSetCookie

boolean canSetCookie(CefCookie cookie)

Return true if the specified cookie returned with the response can be set or false otherwise.

如果可以设置随响应返回的指定cookie，则返回true，否则返回false。

getResponseHeaders

void getResponseHeaders(CefResponse response,
                        IntRef response_length,
                        StringRef redirectUrl)

Retrieve response header information. If the response length is not known set |response_length| to -1 and ReadResponse() will be called until it returns false. If the response length is known set |response_length| 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. To redirect the request to a new URL set |redirectUrl| to the new URL.

检索响应头信息。如果响应长度未知set | response_length | to -1和ReadResponse（）将被调用，直到它返回false。如果响应长度已知set | response_length |到正值并且将调用ReadResponse（），直到它返回false或读取了指定的字节数。使用| response |对象设置mime类型，http状态代码和其他可选标头值。要将请求重定向到新的URL集| redirectUrl |到新的URL。

processRequest

boolean processRequest(CefRequest request,
                       CefCallback callback)

Begin processing the request. To handle the request return true and call CefCallback::Continue() once the response header information is available (CefCallback::Continue() can also be called from inside this method if header information is available immediately). To cancel the request return false.

开始处理请求。处理请求返回true并在响应头信息可用时调用CefCallback :: Continue（）（如果头信息立即可用，也可以从此方法内部调用CefCallback :: Continue（））。要取消请求，请返回false。

readResponse

boolean readResponse(byte[] data_out,
                     int bytes_to_read,
                     IntRef bytes_read,
                     CefCallback callback)

Read response data. If data is available immediately copy up to |bytes_to_read| bytes into |data_out|, set |bytes_read| to the number of bytes copied, and return true. To read the data at a later time set |bytes_read| 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。如果数据可用，请立即复制到| bytes_to_read | bytes到| data_out |，set | bytes_read |到复制的字节数，并返回true。要在以后读取数据| bytes_read |为0，返回true并在数据可用时调用CefCallback :: Continue（）。表示响应完成返回false。
