Abstract
The invention relates to a method for ensuring data transmission integrity in a transmission control protocol (TCP) communication process. The method comprises the following steps of: specifying a special character as the closing tag of each message packet according to a practical situation; detecting whether a data packet to be transmitted comprises the closing tag of the message packet or not and if so, replacing the data packet by other escape character so as to ensure that each complete message packet only comprises one closing tag at most; allowing a client or a server to add a special tag at the end of each integrate data packet to be transmitted; and after the client or the server receives a message, verifying the integrity of the data packet according to the special tag and performing corresponding processing. Due to the adoption of the method, the integrity of the data packet in the TCP communication process is ensured effectively.
Description
Technical field
The present invention relates to the method for transfer of data integrality in a kind of TCP of guaranteeing communication process, particularly a kind of method of guaranteeing data integrity in the TCP communication data reciprocal process by the mode that adds special marking.
Background technology
Adopt between the client and server of Transmission Control Protocol communication; when data interaction is more frequent; because network and all factors that may exist of client and server itself; in fact comprise a plurality of independently packets in a packet that client or server receive appears in regular meeting, perhaps a packet sending of client or server has been splitted into the situation that a plurality of packets send.
Summary of the invention
Technical problem to be solved by this invention provides the method for transfer of data integrality in a kind of TCP of guaranteeing communication process, enhancing program stability.
The method of transfer of data integrality comprises following step at least in a kind of TCP of guaranteeing communication process of the present invention:
Step 1: according to the end mark of spcial character of actual conditions regulation as each message bag.
Step 2: whether comprise＜step 1 in the packet that detection will send〉described in the end mark of message bag.If comprise then replace, to guarantee having only an end mark at most in each complete message bag with other escape character (ESC).
Step 3: client or server add＜step 1 at last each complete data packet that will send〉described in special marking.
Step 4: client or server carry out the packet integrity verification according to special marking after receiving message, and make corresponding processing.
The processing method of a kind of abnormal logging of chess/card game user in server of the present invention, client or server are carried out the packet integrity verification according to special marking after receiving message, and make corresponding processing, the steps include:
Step 41: state a storage of variables, the data of at every turn receiving all are appended in this variable.
Step 42: check＜step 41〉whether comprise＜step 1 in the described storage of variables described in, if do not comprise, then explanation is incomplete packet, is left intact.
Step 43: according to＜step 42〉assay, if do not wrap one or more＜step 1〉described end mark, illustrate that then this packet comprises an a plurality of independently packet. with＜step 1〉the gained end mark is mark, obtains each independently packet.
Step 44: check each independently whether to comprise＜step 2 in the packet〉described in escape character (ESC), it be reduced into corresponding spcial character handle again if comprise then.
Step 45: deletion＜step 41〉data processed bag in the described storage of variables, to avoid the reprocessing of packet.
A kind of method of guaranteeing transfer of data integrality in the TCP communication process of the present invention, the feasible integrality that effectively guarantees with the packet that occurs in the Transmission Control Protocol communication process.
Embodiment
Key step of the present invention is as follows
Step 1: according to the end mark of spcial character of actual conditions regulation as each message bag.
Step 2: the end mark that whether comprises the message bag in the packet that detection will send.If comprise then replace, to guarantee having only an end mark at most in each complete message bag with other escape character (ESC).
Step 3: client or server add special marking at last each complete data packet that will send.
Step 4: client or server carry out the packet integrity verification according to special marking after receiving message, and make corresponding processing.
Above-mentioned steps 4 clients or server carry out the packet integrity verification according to special marking after receiving message, and the concrete steps of making corresponding processing are:
Step 41: state a storage of variables, the data of at every turn receiving all are appended in this variable.
Step 42: check＜step 41〉whether comprise＜step 1 in the described storage of variables described in, if do not comprise, then explanation is incomplete packet, is left intact.
Step 43: according to＜step 42〉assay, if do not wrap one or more＜step 1〉described end mark, illustrate that then this packet comprises an a plurality of independently packet. with＜step 1〉the gained end mark is mark, obtains each independently packet.
Step 44: check each independently whether to comprise＜step 2 in the packet〉described in escape character (ESC), it be reduced into corresponding spcial character handle again if comprise then.
Step 45: deletion＜step 41〉data processed bag in the described storage of variables, to avoid the reprocessing of packet.
Above-mentioned technical scheme can effectively guarantee the integrality with the packet that occurs in the Transmission Control Protocol communication process when implementing.
It should be noted last that above embodiment is only in order to explanation and unrestricted technical scheme described in the invention; Therefore, although this specification has been described in detail the present invention with reference to the above embodiments,, those of ordinary skill in the art should be appreciated that still and can make amendment or replacement to the present invention with being equal to; And all do not break away from the technical scheme and the improvement thereof of the spirit and scope of the present invention, and it all should be encompassed in the middle of the claim scope of the present invention.
Claims (2)
