Description
Technical Field
The present invention relates to the field of data communications, and in particular, to a reverse proxy test method and apparatus, an electronic device, and a storage medium.
Background
The reverse proxy is that after receiving a request from a client, a reverse proxy server obtains a data resource requested by the client from a corresponding back-end server (e.g., a Web server), and then returns the data resource to the client, so that the client only knows an IP (Internet Protocol) address of the reverse proxy server, and the Web server is invisible to the outside, thereby ensuring the security of the data resource of the Web server. Reverse proxies, by which Web services can be provided without exposing a Web server, are often used to control Web site traffic.
However, due to the complexity of the network, reverse proxy services are not available for various reasons during reverse proxy server access and use. Currently, the following reverse proxy test methods are often used to test the connectivity of a reverse proxy server: the client directly accesses the Web server, and the client accesses the Web server through the reverse proxy server and compares the results of the two access modes to judge whether the connectivity of the reverse proxy server is abnormal. However, if the Web server is normally accessed directly by the client and the Web server is abnormally accessed by the client through the reverse proxy server, there is a certain probability that the Web server itself is abnormal when the Web server is accessed through the reverse proxy server, but the reverse proxy server itself is abnormal, so that the connectivity of the reverse proxy server is determined to be abnormal directly, which may cause misjudgment, and thus, the test accuracy of the reverse proxy test method is not high.

The preferred embodiments of the present invention will be described below with reference to the accompanying drawings of the specification, it being understood that the preferred embodiments described herein are merely for illustrating and explaining the present invention, and are not intended to limit the present invention, and that the embodiments and features of the embodiments in the present invention may be combined with each other without conflict.
Referring to fig. 1, which is a schematic view of an application scenario of the reverse proxy testing method according to an embodiment of the present invention, the application scenario may include a client 10, a reverse proxy server 11, a backend server 12-1, and a backend server 12-2, where the client 10 is connected to the reverse proxy server 11 through a network, the reverse proxy server 11 is connected to the backend servers 12-1 and 12-2 through the network, and the backend servers 12-1 and 12-2 may be any servers providing data services, such as a Web server, which is not limited In this embodiment of the present invention, and the reverse proxy server 11 includes a north interface (In) and a south interface (Out). When the client 10 requests the data resource of the back-end server 12-1 or 12-2 from the reverse proxy server 11, the reverse proxy server 11 obtains the data resource requested by the client 10 from the back-end server 12-1 or 12-2 and returns the data resource to the client 10, so as to provide the reverse proxy service for the client 10. The number of the backend servers connected to the reverse proxy server 11 may be several, and the embodiment of the present invention is described by taking the example that the reverse proxy server 11 is connected to two backend servers 12-1 and 12-2.
Among them, the client 10 may be, but is not limited to: smart phones, tablet computers, notebook computers, desktop computers, and the like. The servers 12-1 and 12-2 may be independent physical servers, or may also be cloud servers that provide basic cloud computing services such as a cloud server, a cloud database, and cloud storage, which are not limited in the embodiment of the present invention.
Based on the above application scenarios, an exemplary embodiment of the present invention will be described in more detail below with reference to fig. 2, it should be noted that the above application scenarios are only shown for facilitating understanding of the spirit and principle of the present invention, and the embodiments of the present invention are not limited thereto. Rather, embodiments of the present invention may be applied to any scenario where applicable.
As shown in fig. 2, which is a schematic diagram of an implementation flow of a reverse proxy testing method provided in an embodiment of the present invention, the reverse proxy testing method may be applied to the reverse proxy server 11, and specifically may include the following steps:
s21, the reverse proxy server sends a first data resource request to the connected target back-end server through the northbound interface, and a first request result is obtained.
In specific implementation, the reverse proxy server 11 may actively access a connected target backend server to initiate active probing, where the backend server at least includes a first backend server (i.e., backend server 12-1) and a second backend server (i.e., backend server 12-2), and the target backend server is any one of the first backend server and the second backend server, that is: the target backend server is any one of the backend server 12-1 and the backend server 12-2.
Specifically, the reverse proxy server 11 sends a first data resource request to the connected backend server 12-1 or 12-2 through its northbound interface, and obtains a first request result to check whether the backend server 12-1 or 12-2 can be normally accessed through the northbound interface. The first data Resource request carries a requested data Resource identifier, such as a Uniform Resource Locator (URL) address information, and if the backend server 12-1 or the backend server 12-2 returns data Resource information corresponding to the URL address to the reverse proxy server 11, it is determined that the first request result is normal, and if the backend server 12-1 or the backend server 12-2 does not successfully return data Resource information corresponding to the URL address to the reverse proxy server 11, it is determined that the first request result is abnormal.
In implementation, the first data resource request is randomly sent by the reverse proxy server 11 to the backend server 12-1 or 12-2 according to the internal parameter setting thereof.
And S22, sending a second data resource request to the connected appointed back-end server through the southbound interface, and obtaining a second request result.
In particular, the designated backend server includes at least a first backend server (i.e., backend server 12-1) and a second backend server (i.e., backend server 12-2).
Specifically, the reverse proxy server 11 sends the second data resource request to the first backend server (the backend server 12-1) through its own southbound interface, and records the obtained request result as the first result in the second request result to check whether the backend server 12-1 can be normally accessed through the southbound interface. The second data resource request may be the same as the data resource requested by the first data resource request, that is, the second data resource request and the first data resource request carry the same data resource identifier, that is: the second data resource request carries the same URL address information as the first data resource request, and the second data resource request may also be different from the data resource requested by the first data resource request, that is, the second data resource request and the first data resource request carry different data resource identifiers, that is: the second data resource request and the first data resource request carry different URL address information, which is not limited in the embodiment of the present invention. If the back-end server 12-1 returns the data resource information corresponding to the URL address in the second data resource request to the reverse proxy server 11, it is determined that the first result in the second request result is normal, and if the back-end server 12-1 does not return the data resource information corresponding to the URL address in the second data resource request to the reverse proxy server 11, it is determined that the first result in the second request result is abnormal.
Meanwhile, the reverse proxy server 11 sends the second data resource request to a second backend server (backend server 12-2) through its own southbound interface, and records the obtained request result as a second result in the second request result to check whether the backend server 12-2 can be normally accessed through the southbound interface. If the back-end server 12-2 returns the data resource information corresponding to the URL address in the second data resource request to the reverse proxy server 11, it is determined that the second result in the second request result is normal, and if the back-end server 12-2 does not return the data resource information corresponding to the URL address in the second data resource request to the reverse proxy server 11, it is determined that the second result in the second request result is abnormal.
S23, receiving a third data resource request sent by the client, sending the third data resource request to the target back-end server, and obtaining a third request result.
In specific implementation, the client 10 sends a third data resource request to the reverse proxy server 11 through the northbound interface of the reverse proxy server 11, and the reverse proxy server 11 receives the third data resource request sent by the client through the northbound interface of the reverse proxy server and sends the third data resource request to the target backend server, so as to obtain a third request result, so as to detect whether the client 10 can normally access the target backend server through the reverse proxy server 11. The third data resource request may be the same as or different from the data resources requested by the first data resource request and the second data resource request, and is not described herein again. The target backend server is any one of the first backend server and the second backend server, namely: the target backend server is any one of the first backend server (backend server 12-1) and the second backend server (backend server 12-2), and in the implementation process, the third data resource request is randomly sent to the backend server 12-1 or the backend server 12-2 by the reverse proxy server 11 according to the internal parameter setting thereof. And if the client 10 receives the data resource requested by the client 10 returned by the reverse proxy server 11, determining that the third request result is normal, wherein the data resource received by the client 10 is the data resource requested by the client 10 returned by the back-end server 12-1 or the back-end server 12-2 to the reverse proxy server 11 and is sent to the client 10 by the reverse proxy server 11, and if the client 10 does not receive the data resource requested by the client 10 returned by the reverse proxy server 11, determining that the third request result is abnormal.
S24, determining a reverse proxy test result according to the first request result, the second request result and the third request result.
In specific implementation, the reverse proxy server 10 may determine the reverse proxy test result according to the first request result, the first result in the second request result, the second result in the second request result, and the third request result, and may include at least the following four cases:
in the first case:
and when the first request result is determined to be normal, the first result in the second request result is normal, the second result in the second request result is normal, and the third request result is normal, determining that the communication of the reverse proxy server is normal.
In specific implementation, if the reverse proxy server 11 can normally access the back-end server 12-1 or the back-end server 12-2 through its northbound interface (i.e. when the reverse proxy server 11 sends a first data resource request to the back-end server 12-1 or the back-end server 12-2 through its northbound interface, the back-end server 12-1 or the back-end server 12-2 successfully returns the requested data resource information to the reverse proxy server 11), and the reverse proxy server 11 can normally access the back-end server 12-1 through its southbound interface (i.e. when the reverse proxy server 11 sends a second data request to the back-end server 12-1 through its southbound interface, the back-end server 12-1 successfully returns the requested data resource information to the reverse proxy server 11), and the reverse proxy server 11 can normally access the back-end server 12-2 through its southbound interface (i.e. the reverse proxy server 11) When the proxy server 11 sends the second data request to the backend server 12-2 through its southbound interface, the backend server 12-2 successfully returns the requested data resource information to the reverse proxy server 11), and the client 10 can normally access the backend server 12-1 or the backend server 12-2 through the reverse proxy server 11 (i.e.: the client 10 sends the third data resource request to the reverse proxy server 11 through the northbound interface of the reverse proxy server 11, and after the reverse proxy server 11 sends the third data resource request to the backend server 12-1 or the backend server 12-2, the client 10 successfully receives the data resource requested by the client 10 and returned by the reverse proxy server 11), it determines that the connectivity of the reverse proxy server 11 is normal.
In the second case:
when determining that a first result in the second request results is abnormal, determining that the reverse proxy server is abnormal when accessing the first back-end server; and when a second result in the second request result is abnormal, determining that the reverse proxy server is abnormal when accessing the second back-end server.
In specific implementation, if the reverse proxy server 11 fails to access the backend server 12-1 through its southbound interface (i.e. when the reverse proxy server 11 sends the second data request to the backend server 12-1 through its southbound interface, the backend server 12-1 does not successfully return the requested data resource information to the reverse proxy server 11), it is determined that the access of the reverse proxy server 11 to the backend server 12-1 is abnormal. If the reverse proxy server 11 fails to access the backend server 12-2 through its southbound interface (i.e., the backend server 12-2 does not successfully return the requested data resource information to the reverse proxy server 11 when the reverse proxy server 11 sends the second data request to the backend server 12-2 through its southbound interface), it is determined that the reverse proxy server 11 has an exception to access the backend server 12-2.
In this case, it is described that the access to the backend servers 12-1 and 12-2 through the proxy server 11 is abnormal, but it cannot be described that the reverse proxy server 11 itself is abnormal, and it is necessary to further check whether the path between the proxy server 11 and the backend server 12-1 and the path between the proxy server 11 and the backend server 12-2 are abnormal, and if the path between the proxy server 11 and the backend server 12-1 and the path between the proxy server 11 and the backend server 12-2 are both normal, it is possible to further detect whether the configurations of the backend server 12-1 and the backend server 12-2 are abnormal, so as to accurately locate the abnormal point.
In the third case:
and when determining that a first result in the second request results is normal, a second result in the second request results is normal and the first request result is abnormal, determining that the proxy process of the proxy server is abnormal.
In specific implementation, if the reverse proxy server 11 can normally access the backend server 12-1 through its southbound interface (i.e. when the reverse proxy server 11 sends the second data request to the backend server 12-1 through its southbound interface, the backend server 12-1 successfully returns the requested data resource information to the reverse proxy server 11), and the reverse proxy server 11 can normally access the backend server 12-2 through its southbound interface (i.e. when the reverse proxy server 11 sends the second data request to the backend server 12-2 through its southbound interface, the backend server 12-2 successfully returns the requested data resource information to the reverse proxy server 11), the reverse proxy server 11 fails to access the backend server 12-1 or the backend server 12-2 through its northbound interface (i.e. when the reverse proxy server 11 sends the second data request to the backend server 12-1 through its southbound interface, the reverse proxy server 11 fails to access the backend server 12-1 or the backend server 12-2 through its northbound interface) When the end server 12-2 sends the first data resource request, the back-end server 12-1 or the back-end server 12-2 successfully returns the requested data resource information to the non-reverse proxy server 11), it is determined that the proxy process of the proxy server 11 is abnormal.
In a fourth case:
and when determining that the first request result is abnormal, the first result in the second request result is normal, the second result in the second request result is normal, and the third request result is abnormal, determining that the configuration of the northbound interface network of the reverse proxy server is abnormal.
In specific implementation, if the reverse proxy server 11 fails to access the back-end server 12-1 or the back-end server 12-2 through its northbound interface (i.e. when the reverse proxy server 11 sends a first data resource request to the back-end server 12-1 or the back-end server 12-2 through its northbound interface, the back-end server 12-1 or the back-end server 12-2 successfully returns the requested data resource information to the non-reverse proxy server 11), the reverse proxy server 11 can normally access the back-end server 12-1 through its southbound interface (i.e. when the reverse proxy server 11 sends a second data request to the back-end server 12-1 through its southbound interface, the back-end server 12-1 successfully returns the requested data resource information to the reverse proxy server 11), and the reverse proxy server 11 can normally access the back-end server 12-2 through its southbound interface (i.e. the reverse proxy server 11) When the server 11 sends the second data request to the backend server 12-2 through its southbound interface, the backend server 12-2 successfully returns the requested data resource information to the reverse proxy server 11), and the client 10 fails to access the backend server 12-1 or the backend server 12-2 through the reverse proxy server 11 (i.e.: client 10 sends a third data resource request to reverse proxy server 11 through the northbound interface of reverse proxy server 11, and client 10 does not successfully receive the data resource requested by client 10 returned by reverse proxy server 11), it is determined that the northbound interface network configuration of reverse proxy server 11 is abnormal.
