Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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 some, but not all, embodiments of the present invention. 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.
The link tracing technology is to record all subsystems and execution conditions and execution times of the subsystems that pass through from the beginning to the end of a task, wherein each subsystem that passes through is generally called a node of a link, in other words, a link is composed of at least two nodes. One node on the link may be a terminal device, such as a tablet computer, a mobile phone, a portable computer, or the like, or may be a server device, which is not limited in the present invention.
In the embodiments of the present invention, all nodes constituting a link are classified into two major categories: the first node is located at the head of the link, and the second node is located at the non-head of the link. It is understood that the first node corresponds to an entry of the link, and the other nodes are the second nodes.
In an embodiment of the present invention, as shown in fig. 1, a method for tracing a link exception includes, for a first node located at a head, the following steps:
and S11, acquiring the transaction request information.
Specifically, the transaction request information is a description of specific requirements for the transaction task, such as transaction time, transaction object, transaction amount, transaction mode, and the like. As a specific example, in the bank transfer transaction task, the transaction request information generally includes the transfer amount, the transfer bank card number, the transfer recipient name, the transfer receiving bank card number, the transfer arrival timeliness, and the like. If the operator inputs the transfer transaction information through the mobile phone terminal, the transaction request information is acquired by the mobile phone terminal, and the mobile phone terminal, namely the first node of the link, acquires the transaction request information.
And S12, executing the transaction service logic corresponding to the node according to the transaction request information.
Specifically, after the first node acquires the transaction request information, it decomposes the transaction service logic related to itself according to the transaction request information, and then executes it. For example, after the mobile phone terminal acquires the transfer transaction request information, the validity of the acquired information form needs to be judged, for example, whether the transfer amount is a value larger than zero, whether the number of digits of the card number of the transfer bank card is valid, and the like.
And S13, after the transaction service logic corresponding to the node is executed, generating a call request, wherein the call request comprises the sampling identification.
Specifically, after the first node executes the corresponding transaction service logic, the next node needs to be triggered according to the transaction service, the triggering mode is to transmit a call request to the next node, the call request includes the specific content of the transaction task and the execution result of the service logic of the node, and the position information of the node in the link includes a link number (traceID), a last node number (parentID), a local node execution serial number (spanID), and certainly also includes an identifier of whether the node is sampled. The first node is located at the head of the link and is likely to be a new link, so the traceID in the link structure information needs to be newly generated, the generation rule can be customized, and only the unique corresponding relationship between the serial number and the link needs to be ensured. The parentID in the link configuration information is set to 0, and the spanID is set to 1. On the other hand, the invocation request further needs to include a sampling identifier of the first node, and since the first node is located at the head of the link, the sampling identifier is randomly marked according to a preset percentage sampling rate, for example, the preset percentage sampling rate is 70%, a 01 random number generator is utilized to generate 0 or 1 according to the preset percentage, where 0 represents no sampling, and 1 represents sampling.
And S14, transmitting the call request to a next node adjacent to the node so that the next node executes the transaction service logic corresponding to the next node.
Specifically, the call request is transmitted to the next node adjacent to the node, and there are two types of general transmission manners, one is wired transmission, such as twisted pair, optical fiber, and the like; another is wireless transmission such as bluetooth, wireless broadband (Wi-Fi), etc. Meanwhile, the transmission needs to customize a transmission protocol in advance, and the transmission protocol can be well known, such as an http protocol, and can also be customized. In a specific embodiment, the transmission of the call request may be an active behavior or a passive behavior. The transmission is an active behavior, which means that the first node actively sends a request to the next node according to the self condition, and the transmission is a passive behavior, which means that the service of the next node must depend on the first node, and the first node must transmit a call request to the next node.
And S15, if the transaction service logic of the next node is abnormal, the next node sets the node information of the next node as a sampling node by using the sampling identifier, and transmits the abnormal transaction logic execution result to the node, so that the node information of the node is kept or modified into the sampling node.
Specifically, when a transaction service logic execution exception occurs in a next node adjacent to the first node, where the execution exception includes an execution error or an execution time exceeding a preset threshold, node information of the first node is maintained or modified as a sampling node. It can be understood that if the initial node information of the first node is a sampling node, the node information is maintained without any change; if the initial node information of the first node is a non-sampling node, the node information of the first node needs to be modified into a sampling node. Whether the node information of the first node is maintained or modified depends on the initial node information condition of the first node.
In an embodiment of the present invention, as shown in fig. 2, a link exception tracking, for a second node located at the non-first position of a link, includes the steps of:
and S21, receiving a call request generated by a previous node adjacent to the current node, wherein the call request is generated after the previous node executes corresponding transaction business logic and comprises sampling identification.
Specifically, the second node receives the call request generated by the previous adjacent node, and the specific content includes the link structure information of the previous adjacent node, the execution result of the previous adjacent node, the sampling identifier of the previous adjacent node, and certainly also includes the relevant parameters of the transaction service. The specific form of the request is determined according to the communication mode between the second node and the previous adjacent node, for example, the communication mode between the second node and the previous adjacent node adopts wired network transmission, the communication protocol between the second node and the previous adjacent node generally adopts http protocol, and the call request is combined according to the http protocol form, and the link structure information and the sampling identifier of the previous adjacent node are placed in an http request header for transmission.
And S22, executing the transaction business logic corresponding to the node.
And S23, if the transaction service logic is abnormal, setting the node information of the node as a sampling node by using the sampling identifier, and transmitting the abnormal transaction logic execution result to the previous node, so that the node information of the previous node is kept or modified into the sampling node.
Specifically, the transaction service logic execution exception includes a logic execution error and a logic execution exceeding a preset threshold. It is understood that during the execution of the business logic, execution errors, such as memory leaks, variable boundary violations, etc., often occur due to various reasons. On the other hand, the execution time of the logic exceeds the preset threshold, for example, the logic cannot jump out of the loop due to the wrong use of the loop, and finally the execution is overtime; or due to computational complexity beyond the computing power of the computing device, causing execution timeouts, etc.
In the embodiment of the invention, when the second node has execution abnormity, the execution result needs to be transmitted to the previous node, and further the node information of the previous node is kept or modified into the sampling node. Wherein, the specific step of transmitting the execution result to the previous node includes:
s231, link structure information of the previous adjacent node is obtained.
In a specific embodiment, the previous neighboring node includes the link structure information of the previous neighboring node in the call request transmitted to the node. After receiving the call information, the second node extracts the link structure information of the previous adjacent node according to a relevant communication protocol, and stores the link structure information in a local memory for subsequent use, wherein the link structure information comprises: link number, last node number, self node execution sequence number.
And S232, indexing the previous adjacent node of the node according to the link structure information of the previous adjacent node.
Specifically, according to the link structure information obtained in step S231, index search is performed in the link, and each node in the link corresponds to a unique structure information, so that the previous node can be located very conveniently.
And S233, transmitting the transaction logic execution abnormal result to the previous adjacent node.
Specifically, after the previous node is located, the execution exception result of the node is transmitted to the previous node according to a communication mode with the previous node, where the execution exception result includes an execution error and an execution exceeding a preset threshold, generally, a return code in a local memory is set to be abnormal by the execution error, and an ElaspedFlag in the local memory is set to be abnormal by the execution time exceeding the preset threshold.
And S24, generating a call request after the node executes the corresponding transaction service logic, and sending the call request generated by the node to the next node adjacent to the node until the next node is the last node in the link.
Specifically, the node generates the invocation request after executing the corresponding transaction service logic, and since the invocation request needs to include the link structure information of the node, the step of generating the invocation request includes:
and S241, generating the number of the previous node in the link structure information of the node according to the execution sequence number of the previous node.
In a specific embodiment, in the numbering rule of the link, the parentID of the current node is consistent with the spanID of the previous node, so that the parentID of the node can be generated according to the spanID of the previous node; the traceID of the current node is the same as the previous node, and the spanID of the current node is the order in which it is executed in peer logic according to the current node. For example, if the traceID of the previous node is 01100, the parentID is 3, and the spanID is 2, the traceID of the current node is 01100, the parentID is 2, and the spanID is generated by the current node according to the service logic, for example, the current node is executed first in all peer logics, so the spanID is 1.
And S242, obtaining the call request generated by the node according to the number of the previous node, the link number and the execution sequence number of the node.
Specifically, the current node link structure information is obtained according to step S241, and includes a link number traceID, a previous node number parentID, and an execution serial number spanID of the current node. And combining the link structure information, the sampling identifier of the current node, the execution result and the related parameters of the transaction service according to a communication protocol between the two nodes to obtain a calling request generated by the node.
In an embodiment of the present invention, a method for tracing a link exception includes, for an entire link, the specific steps of:
s31, the first node obtains the transaction request information.
And S32, executing the transaction service logic corresponding to the first node according to the transaction request information.
And S33, generating a call request after the transaction business logic corresponding to the first node is executed, wherein the call request comprises the sampling identification.
And S34, transmitting the call request to a next node adjacent to the first node so that the next node executes the transaction service logic corresponding to the next node.
And S35, if the transaction service logic of the next node adjacent to the first node is abnormal, the next node sets the node information of the next node as a sampling node by using the sampling identifier, and transmits the abnormal transaction logic execution result to the first node, so that the node information of the first node is kept or modified as the sampling node.
S36, the second node receives a call request generated from a previous node adjacent to the second node, wherein the call request is generated after the previous node executes corresponding transaction service logic and comprises a sampling identification.
And S37, executing the transaction business logic corresponding to the second node.
S38, if the transaction service logic of the second node is abnormal, the node information of the second node is set as a sampling node by using the sampling identification, and the abnormal transaction logic execution result is transmitted to the previous node of the second node, so that the node information of the previous node of the second node is kept or modified into the sampling node.
And S39, generating a call request after the second node executes the corresponding transaction service logic, and sending the call request generated by the second node to the next node adjacent to the second node until the next node is the last node in the link.
Specifically, as shown in fig. 3, a scenario is assumed in which a user uses a mobile phone to perform an internal accounting transaction in a bank. This link consists of two nodes: a user mobile phone client and a bank server. The user mobile phone client receives a transfer service request of a user, the mobile phone client sends the request information to the bank server, and the bank server carries out related transaction processing to complete the transfer transaction service. It can be understood that the first node is a user mobile phone client, and the bank server is a second node. All communication between the nodes is transmitted through an http protocol. The steps of anomaly tracking for the entire link are as follows:

s42, the mobile phone client carries out preliminary screening on the relevant information input by the user;
s33, the mobile phone client generates a new traceID, generates parentID and spanID correspondingly, and generates the sampling identification of the current first node (mobile phone client) by using a 01 random number generator; and putting the traceID, the parentID, the spanID and the sampling identifier of the current node into an http request header, and putting the transaction related information input by the user into an http request line to generate the calling request.
And S44, the mobile phone client transmits the generated call request to the bank server through the network.
And S45, after receiving the call request of the mobile phone client, the bank server performs the operation of the related transfer service. If an error occurs in a certain link of the transfer service and the transfer operation cannot be carried out, setting a Return code in a bank server to be abnormal, marking the Return code and a sampling node by the bank server, and simultaneously putting the Return code into an http response body to transmit execution error information to a mobile phone client through a network;
and S46, the mobile phone client receives the execution error information transmitted by the bank server, if the sampling identifier of the mobile phone client is sampling, the execution error information is kept unchanged, and if the sampling identifier of the mobile phone client is not sampling, the mobile phone client modifies the sampling.
