Detailed Description
In the financial field, there are some transaction systems that use duplex network transmission protocols, such as Tuxedo protocol. The request message and the return message of such systems are transmitted using two independent network channels, and there is no pairing information, such as a transaction code, that is obviously used to match the return message with the request message in the messages. For such a system, when performing a function test, a tester needs to match a request message and a return message in the system first, so as to realize simulation of an industrial business scenario in a test playback process. However, matching request messages and return messages for such systems has been a difficult problem in the industry because the messages in such systems do not have obvious pairing information for matching request messages and return messages.
In the prior art, the industry usually relies on manual work to perform recognition piece by piece in the massive system messages, and to match the request messages with the return messages. However, the manual matching method has high labor cost and low matching efficiency.
In order to solve the above problem, in the prior art, a technician inserts a code for generating a message identifier into an application source code, so that a message in a system carries identifier information for identifying the message. And matching the request message with the return message by matching the identification information of the request message with the identification information of the return message. However, inserting a code into an application source code increases the data size of a single message, reduces transmission efficiency, and affects transaction performance.
In order to solve the defects and shortcomings of the prior art, embodiments of the present invention provide a method and an apparatus for matching a message, which can automatically complete matching between a request message and a return message without modifying an application source code or affecting transmission efficiency.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a method for matching a packet provided in an embodiment of the present invention includes the following steps:
s101, respectively grabbing request message data packets in a set time period from a request message network channel and grabbing return message data packets in the same set time period from a return message network channel through a network switch;
in the financial field, there are some transaction systems that use duplex network transmission protocols, such as Tuxedo protocol. The request message and the return message of the system are transmitted by two independent network channels, and the two independent network channels are divided into a request message network channel for transmitting the request message and a return message network channel for transmitting the return message according to different types of the transmitted messages. The two network channels forward the data packet through the same network switch, and on the network switch, the data packets within the same set time period are captured from the two network channels, for example, the data packets within several days, several weeks, or several months are captured.
S102, respectively judging whether the captured data packets are empty, if the captured request message data packets are empty or the returned message data packets are empty, repeatedly and respectively capturing the request message data packets from the request message network channel and capturing the returned message data packets from the returned message network channel, and respectively judging whether the captured data packets are empty until the captured data packets are judged to be non-empty;
the system sends the request message and the return message at random, so that when the network switch captures the data packet, the network switch may not capture the data packet due to accidental factors. Based on the above situation, in the embodiment of the present invention, after the network switch performs the action of capturing the data packet, it is determined whether the captured data packet is empty, and if the captured data packet is empty, the data packet is repeatedly captured until the captured data packet is not empty.
S103, selecting a return message set corresponding to any request message in the request message data packet from the return message data packet by using a time window corresponding to the request message;
for each transaction process, a period of response time is set between the time when the request message is sent and the time when the return message is received. Specifically, for a group of request messages or a request message, the return message corresponding to the group of request messages or the request message is determined to appear in a time window from the moment when the group of request messages or the request message is sent to the moment after the longest response time. Therefore, for a group of request messages or a request message, the return messages in the return message data packet are filtered by using the corresponding time window, and the return messages which are not in the range of the time window are filtered, so that a return message set corresponding to the group of request messages or the request message can be selected from the captured return messages.
For example, assume that an embodiment of the present invention defines a set of request messages for transactions as Qj (j represents a different transaction type )>1), the transmission time of Qj is T0The transaction maximum response time is T. The return message corresponding to the set of request messages must appear at T0,T]Within a time window. Pressing the massive return messages according to [ T ]0,T]And filtering the time window to select a returned text set P. For each group of request messages or each request message, the corresponding returned message set can be selected according to the method.
It should be noted that, in the embodiment of the present invention, after the step S101 is executed, the data packets are respectively captured from the request packet network channel and the return packet network channel, and then a plurality of request packets and return packets are obtained. At this time, when step S103 is executed, for each group of request messages or each request message obtained by capturing, a corresponding return message set is selected by using the time window. The specific selection sequence can be that each group of request messages or a return message set corresponding to each group of request messages are respectively selected from multiple groups of request messages according to the sequence; or according to actual needs, a specific sequence can be specified, and a corresponding return message set is selected for each group of request messages or each request message in the multiple groups of request messages; obviously, the corresponding return text set can also be selected for a plurality of groups of request messages or a plurality of request messages at the same time. The embodiment of the invention only proposes to select the corresponding return message set for the request message by using the time window, and does not limit the specific selection form, and any available selection form can be adopted by the embodiment of the invention.
Furthermore, after selecting the corresponding return message set for each group of request messages or each group of request messages, the subsequent processing steps are respectively continuously executed to find the corresponding return messages until the corresponding return messages are found for all the request messages.
S104, judging whether the selected return message set of the request message is empty, if so, repeatedly executing the following operation for a set number of times: amplifying the time window, and selecting a return text set corresponding to the request message from the captured return messages by using the amplified time window; judging whether the selected return message set is empty, if the selected return message set is judged not to be empty in a certain operation in the set repetition times, stopping repeatedly executing the operation; if the selected return message set is judged to be empty within the set repetition times, confirming that the return message set corresponding to the request message cannot be obtained, and exiting the message matching process;
due to the influence of uncertain factors such as network communication quality, a return message corresponding to a certain group of request messages or a certain request message may not be returned within an expected response time, but may be returned after a period of time, which results in that a return message set corresponding to the request message cannot be selected according to an expected time window, that is, the selected return message set is empty. If the selected return text set is empty, the embodiment of the invention firstly amplifies the time window for selecting the return text set to enlarge the selection range, and then selects the return text set corresponding to the request message from the captured return text again by utilizing the amplified time window. Further, judging whether the selected return message set is empty again, if the selected return message set is still empty, amplifying the time window again, selecting the return message set corresponding to the request message by using the amplified time window, and if the selected return message set is judged not to be empty in a certain operation in the set repetition times, stopping repeatedly executing the operation; if the operation is repeatedly executed for the set times and the selected return message sets are all empty, the return message set corresponding to the request message cannot be obtained, and the message matching process exits.
For example, assume that a set of request messages defining a transaction is Qj (j represents a different transaction type, j)>1), the transmission time of Qj is T0The transaction maximum response time is T. The return message corresponding to the set of request messages should appear at T0,T]Within a time window. Pressing the massive return messages according to [ T ]0,T]Filtering the time window to select a returned message set P, if the selected returned message set P is empty, repeatedly amplifying the time window to be [ T0，(1+n)T]And using a time window [ T ]0，(1+n)T]And selecting a return text set from the return message again. Where n is a positive integer representing the number of times the time window is repeatedly enlarged.
S105, for each return message in the return message set corresponding to the request message, respectively extracting transaction type identification information capable of uniquely identifying the transaction type of the return message;
in a financial system, each set or each return message corresponds to a type of transaction, for example: deposit transactions, withdrawal transactions, transfer transactions, etc. For different types of transactions, information capable of uniquely identifying the type of transaction, namely transaction type identification information, can be extracted from a return message corresponding to a request message of the transaction. The embodiment of the invention respectively extracts the information which can uniquely identify the transaction type corresponding to the return message from the return messages in the return message set so as to carry out type matching on the return message and the request message through the information which uniquely identifies the transaction type of the message.
S106, inputting the transaction type identification information of each return message in the return message set into a Hash algorithm, and calculating to obtain the fingerprint information of each return message;
in general, the transaction type identification information extracted from the return message in step S105 is a character string, and the request message and the return message are directly subjected to type matching by comparing the character strings, which results in large workload and low efficiency. After the transaction type identification information of the return message is obtained, the identification information of the return message is input into a hash algorithm, a hash value is obtained through calculation, and the hash value is used as the fingerprint information of the return message. The fingerprint information is a numerical value, and the type matching of the return message and the request message can be rapidly carried out by comparing the fingerprint information of the return message and the fingerprint information of the request message.
The two types of financial transaction messages, the XML message and the 8583 message, are taken as an example for illustration. And for the XML message, extracting all labels in the message and sequencing the labels into a character string as transaction type identification information of the XML message. Inputting the character string into a Hash algorithm to obtain a Hash value, namely the fingerprint information of the message. For 8583 messages, all message identification bit information is extracted and a character string is formed to serve as transaction type identification information of the 8583 messages, and the character string is input into a hash algorithm to obtain a hash value, namely fingerprint information of the messages.
S107, identifying the transaction type of the request message;
s108, comparing the fingerprint information of the expected return message corresponding to the transaction type of the request message with the fingerprint information of each return message in the return message set respectively, finding out the return message with the fingerprint information same as that of the expected return message corresponding to the transaction type of the request message, and forming a second return message set;
in the software system executing the technical scheme of the embodiment of the invention, an expected return message format template which is calculated in advance and corresponds to the transaction type of the request message is stored, and the fingerprint information of the expected return message is calculated by utilizing a Hash algorithm according to the expected return message format template.
After the transaction type of the request message is identified and obtained, the fingerprint information of the expected return message corresponding to the transaction type is directly called from the database. The fingerprint information of the expected return message is compared with the fingerprint information of the return message in the return message set calculated in step S106, and a new return message set, called a second return message set, is formed by the fingerprint information of the expected return message and the return message with the same fingerprint information of the expected return message. In the second return packet set, the fingerprint information of all return packets is the same as the fingerprint information of the expected return packet, so that the return packets in the second return packet set are matched with the transaction type of the request packet. That is, by step S108, the embodiment of the present invention further selects a return packet with a transaction type matching the request packet from the return packet set.
It should be noted that, in the embodiment of the present invention, transaction type identification information is extracted from a return message, fingerprint information of the return message is obtained through hash algorithm calculation, and the fingerprint information of the return message is compared with fingerprint information of an expected return message corresponding to a request message, so as to find out a return message matching the transaction type of the request message from a return message set through comparison. Theoretically, by comparing any information capable of identifying the transaction type of the message, the return message matched with the transaction type of the request message can be found from the return message set. The method disclosed by the embodiment of the invention is only the most convenient and most common method in practice. The embodiment of the invention does not limit the information used for comparison, and similarly, does not limit the information processing and comparison method, and any information, information processing method and comparison method which can find the return message matched with the transaction type of the request message through comparison are within the protection scope of the embodiment of the invention.
S109, judging whether the second returned message set is empty, if so, repeating the following operations for a set number of times: enlarging the time window, executing the steps S103-S109 again, and stopping executing the operations repeatedly if the second return text set is judged not to be empty in a certain operation in the set repetition times; if the second return text set is judged to be empty within the set repetition times, confirming that the second return text set corresponding to the request message cannot be obtained, and quitting the message matching process;
the second return message set is empty, which indicates that no return message matched with the transaction type of the request message is found from the return message set. At this time, the embodiment of the present invention increases the number of return messages included in the return message set, so that the return message matching the transaction type of the request message can be found from the return message set. Specifically, the time window for selecting the return message set is enlarged, so that the number of return messages contained in the selected return message set is increased. Then, step S103 to step S109 are executed again, and it is determined whether the second returned packet set found from the returned packet set is empty, if the second returned packet set is empty, the time window is enlarged again, and step S103 to step S109 … … are executed, if the time window is enlarged for a certain time within the set number of times, and in the process of step S103 to step S109, it is determined that the selected second returned packet set is not empty, and the above-mentioned operations are stopped from being repeatedly executed; if the selected second return text set is still judged to be empty after the operations are repeatedly executed for the set times, the second return text set corresponding to the request message can be confirmed to be unavailable, and the message matching process is exited.
S110, comparing the transaction key field of the request message with the transaction key field of each return message in a second return message set corresponding to the request message to obtain a return message matched with the request message;
the request message and the return message respectively carry transaction key fields, such as a card number, a customer number, an identification number and the like. For a certain transaction process, the transaction key fields of the request message and the return message are the same. Based on the above principle, due to the previous processing steps in the embodiment of the present invention, the return messages matching the transaction type of the request message in the time window corresponding to the request message are found from a large number of return messages, and a second return message set is formed. Therefore, in this step, the return message that is the same as the transaction key field of the request message, i.e., the return message corresponding to the request message, is found from the second return message set. Further, for a group of request messages, transaction keyword matching is performed on each request message in the group of request messages and the return message in the second return message set, so that the return message corresponding to each request message in the group of request messages can be obtained.
S111, judging whether a return message matched with the request message is obtained or not, and if the return message matched with the request message is not obtained, repeating the following operation for a set number of times: amplifying the time window, and executing the steps S103-S111 again, if judging that the return message matched with the request message is obtained in a certain operation in the set repetition times, stopping executing the operation repeatedly; if the return message matched with the request message is not obtained within the set repetition times, confirming that the return message matched with the request message cannot be obtained, and exiting the message matching process;
if the return message matched with the request message is not found, the number of the return messages contained in the return message set is increased so that the return message matched with the request message can be found from the return message set.
