Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Referring to fig. 1, an embodiment of the present application provides a micro-service early warning method based on a management platform, including the following steps:
s1, receiving a call message which is sent by a first micro service and is accompanied with call information and used for calling a specified micro service, wherein the call message is formed by packaging based on a specified communication protocol, and the call information comprises at least one of a service name, a service URL address or a service function of the specified micro service;
s2, judging whether the specified communication protocol is the same as the preset communication protocol of the specified micro service;
s3, if the specified communication protocol is the same as the preset communication protocol of the specified micro-service, analyzing the calling message according to the format of the specified communication protocol, so as to obtain a calling message header;
s4, calculating the similarity value of the calling message header and a preset standard calling message header by adopting a preset similarity algorithm, and judging whether the similarity value is greater than a preset similarity threshold value;
s5, if the similarity value is larger than a preset similarity threshold value, replacing the calling message header in the calling message with the standard calling message header so as to obtain a replaced calling message;
s6, acquiring the called times of the specified micro service within a preset time according to the calling information, and judging whether the called times are larger than a preset first early warning time threshold value;
and S7, if the called times are larger than a preset first early warning time threshold value, generating early warning information, sending the early warning information and the replaced calling message to the specified micro-service, and adding the specified micro-service into a preset monitoring list by using a preset monitoring plug-in.
As described in step S1, a call packet for calling a specified micro-service and attached with call information is received, where the call packet is encapsulated based on a specified communication protocol, and the call information includes at least one of a service name, a service URL address, or a service function of the specified micro-service. A microservice is the breakdown of an application into small, interconnected microservices, as opposed to monolithic applications (which centralize all functionality in one application). One microservice generally performs a specific function, and can also call or be called by other microservices, thereby collectively performing all or part of the functions of an application. The management platform of the present application refers to a platform for managing microservices, wherein management includes management in any feasible manner, such as microservices registration, microservices discovery, gateway control, data monitoring, and the like. According to the method and the system, management of the micro-services is carried out through the management platform, so that the micro-services do not need to expose too much information to the outside, only one of the service names, the service URL addresses or the service functions needs to be exposed, when one of the information is attached to the calling message, the management platform can determine the accurate micro-services from the pre-stored corresponding table, the method and the system are more convenient and faster, and the information safety is improved.
As described in the above step S2, it is determined whether the specified communication protocol is the same as the preset communication protocol of the specified micro-service. And if the specified communication protocol is different from the preset communication protocol of the specified micro-service, the specified micro-service cannot be directly sent to the specified micro-service according to the calling request. Therefore, whether the specified communication protocol is the same as the preset communication protocol of the specified micro service is judged. The determining whether the specified communication protocol is the same as the preset communication protocol of the specified micro service may be performed in any manner, for example, the determining may include: judging whether the first micro service and the specified micro service belong to a preset micro service cluster; if the first micro service does not belong to a preset micro service cluster and the specified micro service belongs to the preset micro service cluster, checking whether the calling request is legal or not according to a preset validity check rule; and if the calling request is legal, judging whether the communication protocol of the calling request is the same as the preset communication protocol of the specified micro service. Thereby determining whether a conversion between communication protocols is required.
As described in step S3, if the specified communication protocol is the same as the preset communication protocol of the specified micro service, the call packet is parsed according to the format of the specified communication protocol, so as to obtain a call packet header. Generally, a message is composed of a header and a message body, and the headers of different communication protocols are different, for example, the format of an HTTP request message is: a request line, a request HEADER (HTTP request HEADER, also known as HEADER), and a requestor. Accordingly, the calling message is analyzed according to the format of the specified communication protocol, and a calling message header is obtained.
As described in step S4, a preset similarity algorithm is used to calculate a similarity value between the call packet header and a preset standard call packet header, and determine whether the similarity value is greater than a preset similarity threshold. In some situations, a small number of errors may occur in the header, such as partial character errors, for example, a Content-Type: application/json, a charset = utf-8 error is written as association/json, a charset = utf-8, and so on. The conventional technology cannot identify the wrong message header, so that the rejection operation is performed. According to the method and the device, the correct message header is replaced by the wrong message header, so that the network overhead is reduced, and the information transmission efficiency is improved. The standard calling message header can be called from a preset message header library. The method for calculating the similarity value between the calling message header and the preset standard calling message header by using the preset similarity algorithm can adopt any algorithm, such as an overlapped word algorithm and the like. Therefore, whether the calling message header is wrong or not, only the correct message header needs to be replaced.
As described in step S5, if the similarity value is greater than the preset similarity threshold, the call packet header in the call packet is replaced with the standard call packet header, so as to obtain a replaced call packet. If the similarity value is greater than a preset similarity threshold value, it is indicated that the preset standard calling message header is the same as the calling message header, and if the calling message header is replaced by the preset standard calling message header, the recognition of the calling message is not affected no matter whether the calling message header is wrong or not.
As described in step S6, according to the calling information, the called times of the specified micro service within a predetermined time are obtained, and it is determined whether the called times are greater than a preset first warning time threshold. The calling information comprises at least one of a service name, a service URL address or a service function of the specified micro service, and the management platform can determine the specified micro service according to the calling information, further can obtain the called times of the specified micro service within preset time, and judges whether the called times are larger than a preset first early warning time threshold value or not so as to determine whether the specified micro service is in an abnormal state or not.
As described in step S7, if the called number of times is greater than the preset first warning number threshold, generating warning information, sending the warning information and the replaced call packet to the specified micro-service, and adding the specified micro-service to a preset monitoring list using a preset monitoring plug-in. If the called times are larger than a preset first early warning time threshold value, indicating that the specified micro service is possibly in an abnormal state, generating early warning information according to the early warning information, and meanwhile adding the specified micro service into a preset monitoring list by using a preset monitoring plug-in. The management platform adopts a monitoring stripping mode, and functions such as data embedding points of monitoring and the like are realized through the monitoring plug-in, so that the influence on aspects such as server containers, loads, networks and the like when the monitoring setting is required to be adjusted is avoided. Wherein, the adding of the specified micro-service into the preset monitoring list can be realized by modifying byte codes through java agent. Further, still include: if the called times are greater than a preset second early warning time threshold value, rejecting the calling message, wherein the second early warning time threshold value is greater than the first early warning time threshold value, carrying out classification processing on the calling application in an abnormal condition, and when the called times are higher but are still in a tolerable state (namely the first early warning time threshold value), generating early warning information, sending the early warning information and the replaced calling message to the specified micro-service, and adding the specified micro-service into a preset monitoring list by using a preset monitoring plug-in; and when the called times are higher but in an intolerable state (namely a second early warning time threshold), rejecting the calling message.
In one embodiment, before the step S2 of determining whether the specified communication protocol is the same as the preset communication protocol of the specified micro service, the method includes:
s11, judging whether the first micro service and the specified micro service belong to the same micro service cluster;
s12, if the first micro service and the specified micro service do not belong to the same micro service cluster, judging whether the calling message carries an identity token, wherein the identity token is identity authentication information generated by the management platform for the first micro service;
s13, if the calling message carries an identity token, judging whether the identity token carried by the calling message has the authority to call the specified micro-service according to the corresponding relation between the preset identity token and the authority;
s14, if the identity token carried by the calling message has the authority of calling the specified micro-service, judging whether the calling parameter of the calling message is matched with the preset parameter of the specified micro-service;
and S15, if the calling parameter of the calling message is matched with the preset parameter of the specified micro service, generating a communication protocol judgment instruction, wherein the communication protocol judgment instruction is used for indicating whether the specified communication protocol is the same as the preset communication protocol of the specified micro service.
As described above, generation of the communication protocol determination instruction is realized. In order to ensure correct message identification, the method also judges whether the first micro service and the specified micro service belong to the same micro service cluster before judging whether the specified communication protocol is the same as the preset communication protocol of the specified micro service; judging whether the calling message carries an identity token or not; judging whether the identity token carried by the calling message has the authority of calling the specified micro-service or not; and a multi-step judgment process for judging whether the calling parameters of the calling message are matched with the preset parameters of the specified micro-service or not so as to ensure that the calling message has a recognized basis, and generating a communication protocol judgment instruction on the basis. The process of generating the identity token in advance comprises the following steps: the first micro service sends an identity authentication application to the management platform; the management platform sends and generates identity authentication information and sends the identity authentication information to the first micro service; the first microservice receives and stores the identity token. The fact that the calling parameter of the calling request is matched with the preset parameter of the specified micro service means that the calling parameter does not exceed the range specified by the preset parameter of the specified micro service, for example, the length of the storage field is in the preset range.
In an embodiment, the step S3 of, if the specified communication protocol is the same as the preset communication protocol of the specified micro service, parsing the call packet according to the format of the specified communication protocol to obtain a call packet header, includes:
s301, if the specified communication protocol is the same as the preset communication protocol of the specified micro-service, determining the position of a message header in the calling message according to the format of the preset specified communication protocol;
s302, judging whether the content in the position of the message header conforms to a preset format of the message header;
s303, if the content in the position of the message header conforms to the preset format of the message header, extracting the content in the position of the message header and recording the content as a calling message header.
As described above, obtaining a call header is achieved. The call message generally includes a message header and a message body, wherein if the format of the message header does not match the format that the preset message does not have, the call message is definitely not recognized, and because the formats do not match, the call message cannot be corrected to determine the correct message header. Therefore, the scheme of firstly judging whether the content in the position of the message header conforms to the preset format of the message header is adopted in the application. In which, a format of a communication protocol is exemplified: the format of the predetermined communication protocol is a request line, a request header and a request body (for example, the format of the HTTP communication protocol), wherein a first line break exists between the request line and the request header, and an empty line exists between the request header and the request body, for example. The position of the message header in the calling message can be determined only by finding the first line feed character and finding the first empty line in the calling message. Then, whether the Content in the position of the message header conforms to the preset format of the message header is judged, for example, whether the Content-Type: [ Type ]/[ subtype ]; and the format of the parameter exist is judged.
In one embodiment, the step S4 of calculating a similarity value between the call packet header and a preset standard call packet header by using a preset similarity algorithm, and determining whether the similarity value is greater than a preset similarity threshold value includes:
s401, adopting a formula:
calculating the similarity value of the calling message header and a preset standard calling message header; wherein A is the character frequency vector of the calling message header, B is the character frequency vector of the preset standard calling message header, Ai、BiThe ith component vectors of the vectors A and B are respectively, n is the component quantity value with the largest component vector quantity in the vectors A and B, and whether the similarity value is larger than a preset similarity threshold value or not is judged.
As described above, the similarity value between the calling message header and the preset standard calling message header is calculated by using the preset similarity algorithm, and whether the similarity value is greater than the preset similarity threshold is determined. And calculating the similarity value of the calling message header and a preset standard calling message header by adopting a cosine similarity calculation method. And the character frequency vector of the calling message header refers to the occurrence frequency of characters in the calling message header. For example, the character frequency vector of Content is (1,1,2,2,1), that is, except n and t appearing 2 times, other characters appear only 1 time, where 2 in (1,1,2,2,1) is the component vector of n and t. Therefore, the similarity value of the calling message header and the preset standard calling message header is calculated by adopting a cosine similarity calculation method. Further, the calculating a similarity value between the calling header and a preset standard calling header by using a preset similarity algorithm, and determining whether the similarity value is greater than a preset similarity threshold value further includes: calculating similarity values of the calling message header and a plurality of preset standard calling message headers by adopting a preset similarity algorithm so as to obtain a plurality of similarity values, and judging whether the maximum value of the similarity values is greater than a preset similarity threshold value or not; and if the maximum value of the similarity values is larger than a preset similarity threshold value, taking the standard call message header corresponding to the maximum value of the similarity values as a correct call message header.
In an embodiment, before the step S6 of acquiring, according to the call information, the number of times of calls of the specified micro service in a predetermined time and determining whether the number of times of calls is greater than a preset first warning number threshold, the method includes:
s51, executing the recognition command of the replaced call message;
s52, judging whether the process of executing the identification command is error;
and S53, if the process of executing the identification command is not wrong, generating an early warning judgment instruction, wherein the early warning judgment instruction is used for indicating that the called times of the specified micro service within the preset time are obtained according to the calling information, and judging whether the called times are larger than a preset first early warning time threshold value.
As described above, the recognition command is executed, so that whether the replaced call packet is correct or not is judged. Although the call message is subjected to replacement processing, in order to further ensure that the call message can be identified, the application also executes an identification command of the call message after replacement; and judging whether the process of executing the identification command reports an error or not so as to ensure that the calling message can be correctly identified. And if the process of executing the identification command is not wrong, generating an early warning judgment instruction, wherein the early warning judgment instruction is used for indicating that the called times of the specified micro service within the preset time are obtained according to the calling information, and judging whether the called times are greater than a preset first early warning time threshold value or not.
In an embodiment, after the step S6 of acquiring, according to the invocation information, the invoked number of times of the specified micro service within a predetermined time, and determining whether the invoked number of times is greater than a preset first warning number threshold, the method includes:
s61, if the called times are not larger than a preset first early warning time threshold value, counting the flow data of the specified micro service within preset time, and judging whether the distribution of the flow data along with the change of time is within a preset flow data distribution range;
and S62, if the distribution of the flow data along with the change of time is in a preset flow data distribution range, sending the replaced call message to the specified micro service.
As described above, the transmission of the replaced call packet to the specified microservice is realized. The specified micro service is in an abnormal state and may be related to factors such as time, so that only the calling times within the preset time are judged to possibly cause inaccurate judgment, and accordingly, the mode of counting the traffic data of the specified micro service within the preset time and judging whether the distribution of the traffic data along with the change of time is within the preset traffic data distribution range is adopted to determine whether the traffic data of the specified micro service is normal. If the distribution of the flow data along with the change of time is in a preset flow data distribution range, the flow data is not abnormal, and therefore the replaced call message is sent to the specified micro service. The flow data distribution range may be set in any manner, for example, set as the real value of the flow data in the previous period multiplied by (-M%, + M%), where M is greater than 0.
In one embodiment, the step S7 of generating warning information, sending the warning information and the replaced call packet to the specified micro-service, and adding the specified micro-service to a preset monitoring list using a preset monitoring plug-in if the called number is greater than a preset first warning number threshold, includes:
s701, if the called times are larger than a preset first early warning time threshold value, generating early warning information, and sending the early warning information and the replaced calling message to the specified micro-service;
s702, byte code modification is carried out by using a preset monitoring plug-in based on the java agent technology, so that data embedding points are added at a communication port of the specified micro-service, and the specified micro-service is added into a preset monitoring list.
As described above, the early warning information and the replaced call packet are sent to the specified micro-service, and the specified micro-service is added to a preset monitoring list by using a preset monitoring plug-in. The java agent technology is a computer system packaged in a certain environment based on java language, and can flexibly and autonomously act in the environment for realizing the design purpose.
