In view of the above, in the current testing method for the CDN back-source abnormality, it is difficult to finely control the time for disconnecting the CDN network from the source station, so that it is difficult to comprehensively test various situations of the CDN back-source abnormality.
Based on this, the embodiment of the invention provides a method and a device for testing a CDN back source abnormity and a terminal device, and the technology can be applied to a testing scene of the CDN back source, especially a testing scene of the back source abnormity. In order to facilitate understanding of the embodiment, a detailed description is first given of a method for testing a CDN network back source anomaly disclosed in the embodiment of the present invention, where the method is applied to a terminal device, and the terminal device is connected to a preset simulated source station through a target CDN network; the terminal device may be a computer, or may be a mobile terminal (e.g., a mobile phone, a tablet computer, etc.); as shown in fig. 1, the method comprises the steps of:
step S102, receiving a source returning test request for a target CDN network triggered by a user; wherein, the back source test request comprises a designated back source response instruction; the source return response instruction is used for indicating the response mode of the simulation source station responding to the source return test request.
A user may generally trigger a back source test request at a terminal device, where the back source test request may be an http (Hypertext Transfer Protocol) request, an https (Hypertext Transfer Protocol Secure) request, or a request corresponding to another transmission Protocol. In the process of the CDN back-source abnormity test, a specified back-source response instruction can be added in the back-source test request, the back-source response instruction is used for indicating a response mode of the simulation source station responding to the back-source test request, the response mode can be a mode of interrupting the response after the simulation source station responds to how much data, or a mode of directly closing the connection between the CDN network and the simulation source station in the request without responding to the data, and the response mode can be set according to the requirements of testers, so that the disconnection time of the CDN network and the simulation source station can be finely controlled based on the response mode.
And step S104, sending the back source test request to a simulation source station through a target CDN network so that the simulation source station responds to the back source test request based on a back source response instruction.
The back source test request has a certain corresponding relationship with the CDN network, that is, which CDN network needs to be used when the back source test request uses the domain name to access data is preset. Therefore, when the terminal device sends the back source test request, the CDN network corresponding to the back source test request may be determined according to a domain name resolution method, and the CDN network is determined as a target CDN network, so that the back source test request carrying the back source response instruction is sent to the simulated source station corresponding to the target CDN network through the target CDN network. After receiving the back-source test request, the simulation source station may respond to the back-source test request based on a response mode in the back-source response instruction, and return response data to the terminal device.
The invention provides a method for testing CDN back source abnormity, which comprises the following steps that firstly, terminal equipment receives a back source test request for a target CDN network, wherein the back source test request is triggered by a user; wherein, the back source test request comprises a designated back source response instruction; the source return response instruction is used for indicating a response mode of the simulation source station for responding to the source return test request; and then sending the back-source test request to the simulation source station through the target CDN, so that the simulation source station responds to the back-source test request based on the back-source response instruction. According to the mode, the response mode that the simulation source station responds to the back source test request is controlled through the back source response instruction in the back source test request, so that the disconnection time of the CDN and the simulation source station is finely controlled, various conditions of CDN back source abnormity can be comprehensively tested, meanwhile, the mode only disconnects the current back source test request and the simulation source station, the influence on other tests of the CDN performed in parallel is avoided, and the overall test efficiency is improved.
The embodiment of the invention also provides another testing method for the CDN back source abnormity, which is realized on the basis of the method in the embodiment; the method mainly describes a response mode corresponding to a back source response, namely a testing process of CDN network back source abnormity and a specific process of data format conversion before request transmission (realized by the following step S204) when simulating the data volume of response data corresponding to a back source test request returned by a source station; as shown in fig. 2, the method comprises the steps of:
step S202, receiving a source returning test request for a target CDN network triggered by a user; the back source test request comprises a designated back source response instruction; the source return response instruction is used for indicating a response mode of the simulation source station for responding to the source return test request; the response mode comprises the following steps: and the simulation source station returns the data volume of the response data corresponding to the back source test request.
The response mode is used for indicating the data volume of response data corresponding to the source returning test request returned to the terminal equipment by the analog source station, and the data volume can be identified by numbers or character strings. During specific implementation, the time for disconnecting the CDN network from the analog source station in the current back-to-source test request, that is, after the analog source station returns response data of the data amount set in the response mode for the terminal device, the connection between the CDN network and the analog source station in the current back-to-source test request is disconnected (it may also be understood that the analog source station does not send response data to the terminal device any more).
In a specific implementation, the back source response instruction includes: presetting an instruction name and an instruction value; wherein the instruction value is to indicate: and the simulation source station returns the data volume of the response data corresponding to the source test request.
The instruction value may be set to a specific value, where the value is used to instruct the simulation source station to return the data volume of the response data corresponding to the source test request, and when the instruction value is specifically set, different values may be defined as different data volumes according to the requirements of the tester. For example, a negative number, zero, or positive number, etc., may be set. In a specific implementation, the back source test instruction may be represented as "instruction name: the format of the instruction value "may be other formats.
In some embodiments, the instruction name may be an expect-abort, which is typically a request message header, and the value of the expect-abort is typically a desired condition, indicating that the request can only be properly processed if the desired condition is satisfied; the expected condition may be set to the data amount of the response data corresponding to the source test request returned by the simulation source station indicated by the instruction value.
In some embodiments, the data amount of the response data corresponding to the back source test request may be any one of the following data amounts:
1. and returning the complete response data corresponding to the source test request. In specific implementation, the complete response data usually includes header information and actual data, where the actual data may be data that needs to be accessed by the backlog request, such as images, videos, audios, apks (android packages), and compressed packages; the header information is used for indicating the back source state of the back source test request, and the back source state can be back source normal or back source abnormal; the header information may also contain some descriptive information.
2. Header information of response data corresponding to the back source test request, and partial response data specifying the data amount.
The specified data amount is the data amount indicated in the response mode, and the partial response data of the specified data amount is the data of the specified data amount in the actual data.
3. And returning the header information of the response data corresponding to the source test request.
4. Zero data volume; i.e. the simulation source station does not return any data to the terminal device.
Step S204, converting the format of the back source test request into a format matched with a preset network transmission protocol; in the converted back-to-source test request, the back-to-source response instruction is set in a request header or a URL of the back-to-source test request.
The network transmission protocol can be an http protocol or an https protocol. Specifically, the above-mentioned back-source response instruction may be added to a request header or a URL (Uniform Resource Location) in the back-source test request, where the URL is usually a character string used to describe the information Resource; the request header may typically be used to set date, data type, browser type, etc. For example, the format of the back source test request is converted into a format matched with the http protocol, and the back source response instruction is set in an expect-abort request header, so the back source test request may be www.test.com/video/mp 4/test. mp4, and the request header is expect-abort: 1048576; the back source response instruction is set in the URL parameter of the back source test request, which can be represented as http:// www.test.com/video/mp 4/test. mp4expect _ abort 1048576.
In specific implementation, the back source response instruction is put into the request head, extra operation is not needed, and an abnormal response scene can be simulated, so that the test efficiency is improved.
Step S206, sending the back-source test request to the simulation source station through the target CDN network, so that the simulation source station responds to the back-source test request based on the data size of the response data corresponding to the back-source response instruction.
In specific implementation, based on the transparent transmission characteristic of the CDN network, the CDN network may send a back source test request sent by the terminal device to a simulated source station corresponding to the target CDN network, where the simulated source station may analyze a back source response instruction in the back source test request after receiving the back source test request, and respond to the back source test request according to a data amount in the back source response instruction.
In order to facilitate understanding of the above embodiments, the following description takes an example of adding a request header expect-abort to a back-source test request, where when the value of expect-abort is not a number, it indicates that the simulation source station returns complete response data corresponding to the back-source test request; when the value of expect-abort is negative, the simulation source station does not return any data; when the value of expect-abort is zero, the simulation source station returns the head information of the response data corresponding to the source test request; when the value of expect-abort is zero, the simulation source station returns the header information of the response data corresponding to the source test request and the partial response data of the specified data volume.
For example, the simulation source station parses out expect-abort:1, after receiving a back source test request, the simulation source station directly closes the connection with the back source test request, and does not respond to any data of the CDN network, that is, does not respond to any data of the terminal device; if the expect-abort is 0, the simulation source station receives the back source test request, and closes the connection with the back source test request after responding the head information of the back source test request, namely only responding the head information of the terminal equipment; if expect-abort:1048576, the simulation source station receives the back-source test request, after responding to the header information of the back-source test request and 1048576 bytes (equivalent to 1 mbyte) of response data, closes the connection with the back-source test request, that is, only responds to the header information of the terminal device and 1 mbyte of response data (also called actual data), and does not respond to the complete response data.
According to the method for testing the CDN network back-source abnormity, the back-source response instruction is added in the back-source test request, so that the simulation source station returns the data volume of the response data of the back-source test request according to the back-source response instruction, the data volume of the response data in the abnormal response of the simulation source station can be accurately controlled, other tests which are performed aiming at the target CDN network cannot be influenced, other people using the simulation source station to perform tests cannot be influenced, the test efficiency and coverage are improved, the quality and stability of CDN service are improved, the parallel execution of the tests is realized, and CDN equipment resources and human resources can be saved.
Corresponding to the above embodiment, another testing method for CDN network back source anomaly is also provided in the embodiments of the present invention, where the method is applied to a server running a simulated source station, where the simulated source station is connected to a terminal device through a target CDN network; as shown in fig. 3, the method comprises the steps of:
step S302, receiving a back source test request sent by a target CDN; wherein, the back source test request comprises a designated back source response instruction; the source return response instruction is used for indicating the response mode of the simulation source station responding to the source return test request.
Step S304, extracting a source return response command from the source return test request.
In particular implementation, the back source response instruction can be extracted and parsed according to the instruction name of the back source response instruction.
In some embodiments, the response mode includes: and the simulation source station returns the data volume of the response data corresponding to the source test request. Specifically, the back source response instruction includes: presetting an instruction name and an instruction value; wherein the instruction value is to indicate: and the simulation source station returns the data volume of the response data corresponding to the source test request.
The instruction value may be set to a specific value, where the value is used to instruct the simulation source station to return the data volume of the response data corresponding to the source test request, and when the instruction value is specifically set, different values may be defined as different data volumes according to the requirements of the tester. For example, a negative number, zero, or positive number, etc., may be set. In a specific implementation, the back source test instruction may be represented as "instruction name: the format of the instruction value ". Preferably, the above-mentioned back source response instruction may be added to a request header or URL of the back source test instruction.
And step S306, responding to the back source test request based on the back source response instruction.
In a specific implementation, the simulation source station may respond to the back-source test request according to the data volume of the response data corresponding to the back-source test request returned by the simulation source station included in the response mode, and return the corresponding result to the terminal device. Specifically, the step S306 may include one or more of the following steps:
1. and if the data volume of the response data corresponding to the source returning test request is complete response data, returning the complete response data corresponding to the source returning test request to the terminal equipment.
2. If the data volume of the response data corresponding to the source returning test request is the header information and the partial response data of the designated data volume, returning the header information of the response data corresponding to the source returning test request and the partial response data of the designated data volume to the terminal equipment; the header information is used to indicate the back source status of the back source test request.
3. And if the data volume of the response data corresponding to the back source test request is the header information of the response data, returning the header information of the response data corresponding to the back source test request to the terminal equipment.
4. And if the data volume of the response data corresponding to the back source test request is zero data volume, not returning any response data corresponding to the back source test request to the terminal equipment.
In the method for testing the back-source abnormity of the CDN, when a server corresponding to a simulation source station receives a back-source test request sent by a target CDN, a back-source response instruction is extracted from the back-source test request; the source return response instruction is used for indicating a response mode of the simulation source station for responding to the source return test request; and then responds to the back source test request based on the back source response instruction. According to the method, the response mode of the simulated source station responding to the back source test request is controlled through the back source response instruction in the back source test request, so that the simulated source station can perform data response according to the response mode, the disconnection time of the CDN network and the simulated source station can be finely controlled, various conditions of CDN back source abnormity can be comprehensively tested, meanwhile, the mode only disconnects the current back source test request and the simulated source station, the influence on other tests of the CDN network performed in parallel is avoided, and the overall test efficiency is improved.
The embodiment of the invention also provides another testing method for the CDN back source abnormity, which is realized on the basis of the method in the embodiment; the method comprises the steps that a terminal description feedback source response instruction is arranged on an expect-abort request header of a feedback source request, and a specific process that a source station carries out feedback source request response is simulated according to an instruction value on the request header; the method is applied to a server corresponding to a simulation source station, and as shown in fig. 4, the method includes the following steps:
step S402, receiving a back-source test request for the target CDN network from the terminal device.
In this embodiment, the function may be implemented on the simulation source station, so that the simulation source station may implement different abnormal response behaviors according to a value of a request header carried in a return source test request sent by the terminal device.
Step S404, judging whether the back source test request contains an expect-abort request header; if yes, go to step S406, otherwise go to step S412.
Specifically, by using the transparent name transmission characteristic of the CDN network, the analog source station receives the returnable source test request and parses an expect-abort request header added during testing.
Step S406, judging whether the expect-abort request header contains a number; if the digital code is included, step S408 is executed, otherwise, step S412 is executed.
If the echo-abort test request carries an expect-abort request header and the value is a number, the analog source station needs to perform abnormal response when representing the test.
Step S408, judging whether the number contained in the expect-abort request header is a negative number; if not, go to step S410; if it is negative, go to step S414.
Step S410, judging whether the number contained in the expect-abort request header is zero or not; if yes, go to step S416; if not, step S418 is performed.
Step S412, returning the complete response data corresponding to the source returning test request to the terminal equipment; and finishing the response.
Step S414, no response data corresponding to the source return test request is returned to the terminal equipment; and finishing the response.
Step S416, after returning the header information of the response data corresponding to the back source test request to the terminal device, closing the connection with the target CDN network; and finishing the response.
Step S418, after returning the header information of the response data corresponding to the back source test request and the response data of the number of bytes corresponding to the number to the terminal device, closing the connection with the target CDN network; and finishing the response.
If the number is a positive number, it indicates that the analog source station can return the header information of the response data corresponding to the ring test request and the number of bytes of response data corresponding to the positive number to the terminal device, for example, 1048576 bytes (equivalent to 1 mbyte) of response data can be responded to when the number is 1048576.
