方法详细资料

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.

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.

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.

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.

canSetCookie

boolean canSetCookie(CefCookie cookie)

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

cancel

void cancel()

Request processing has been canceled.
