Equipment, to realize subsequent application program reparation.
S2: it is parsed to agreement is received, obtains repair data, while knowing module to be repaired corresponding to repair data
Title, the step specifically:
S201: after equipment receives agreement, and creating the instance objects of message parsing type, and the function of message parsing is
DataDecoder。
The instance objects of function DataDecoder are DataDecoder*pDecoder=newDataDecoder (),
P expression parameter before pDecoder, is the classification of the variable of auto-complete, and Decoder expression is converted to encoded byte sequence
One group of character；After the completion of instance objects creation, it can start to parse message, execution code is pDecoder- > Parse
(buf), Parse (buf) indicates parsing message.
S202: parsing agreement using the instance objects of creation, obtain repair data, module title to be repaired, to
The offset of repair module and protocol type.Resolving are as follows:
The protocol type in agreement is parsed using code stringtype=pDecoder- > GetItemAs (" type ")
Field learns that the agreement is suitable for carrying out vulnerability of application program reparation, and specifically for the native layer to application program into
Row is repaired；It is parsed from agreement using code stringmdn=pDecoder- > GetItemAs (" modulename ") to be repaired
Multiple module title field；Using code stringmdo=pDecoder- > GetItemAs (" moduleoffset ") from agreement
Parse the offset field mdo of module to be repaired；It uses code stringdata=pDecoder- > GetItemAs (" data ")
Repair data field is parsed from agreement；So far, repair data, module title to be repaired, module to be repaired have just been obtained
Offset and protocol type.
S203: based on obtained repair data, module title to be repaired, the offset of module to be repaired and protocol type, wound
