Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present specification. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the specification, as detailed in the appended claims.
The terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the description. As used in this specification and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
It should be understood that although the terms first, second, third, etc. may be used herein to describe various information, these information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, the first information may also be referred to as second information, and similarly, the second information may also be referred to as first information, without departing from the scope of the present specification. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.
At present, a user carries information of managed equipment to be accessed through a browser (or an appointed APP) and directly accesses the equipment through a cloud management platform, the cloud management platform only has one port for the function, and all the accessed equipment needs to be accessed through the port.
Since there is only one session under the same domain on one browser. This means that the user cannot access multiple managed devices through the same browser through the cloud at the same time. If a user accesses multiple managed devices, it may happen that when accessing a second device, the web page is switched so that the page accessing the first device will also be the local management of the second device being accessed.
In order to solve the above technical problem, an embodiment of the present disclosure provides an access method for a device, as shown in fig. 1, the method is applied to a cloud management platform, where the cloud management platform is connected to a managed device, and the method includes:
s101, receiving an access request sent by a user, wherein the access request carries target user key information used for representing the user to access target managed equipment;
s102, matching the key information of the target user with a configured port table;
s103, if the matching fails, judging whether an unallocated target port exists in the port table, and if so, allocating the target port to a user.
In this embodiment, the cloud management platform may be applied to a network device with storage and processing capabilities, for example: servers, network managers, etc.
In this embodiment, the cloud management platform and the managed device may form a cloud device, and the user may be a terminal device disposed outside the cloud device, such as a computer, a mobile phone, a tablet computer, an intelligent wearable device, and the like.
In this embodiment, two types of ports may exist between the user and the cloud management platform, one type of port is a universal port, and when the user accesses the cloud management platform for the first time (or does not obtain access to the managed device port), the user may access the cloud management platform through the universal port. The other type of port is a dedicated port, the dedicated port is allocated to a user by the cloud management platform, so that the user can access the port of the managed device.
In step S101, when the user sends the access request, the user carries target user key information of the target managed device to be accessed, where the target user key information may be, for convenience of description, subsequently set the user key information as key and the target user key information as key1 according to the user information (e.g., user name and password) of the user and the information (e.g., IP information of the target managed device) of the target managed device to be accessed.
TABLE 1
As shown in table 1, exemplary ports that are not allocated to users and ports that are allocated to users are recorded in the port table (in other embodiments, all ports that are not allocated to users or all ports that are allocated to users are recorded in the port table).
In step S102, the target user key information is used to match the configured port table, and a specific process may be to match the key1 in the access request with an entry in the port table and output a matching result, where the matching result may be that the matching is not successful or the matching is successful.
In an implementation case, before sending an access request carrying key1 of a target user, a user already sends an access request carrying key2 to a cloud management platform, as shown in table 1, the cloud management platform allocates a dedicated port 1 to the user, and subsequently, when the user sends an access request carrying key1, the cloud management platform performs traversal matching on a port table by using key1, and if the matching is not successful, the cloud management platform may allocate an unallocated dedicated port 3 to the user. If the matching is successful, it indicates that the same user has already acquired the dedicated port for the same managed device, and at this time, the dedicated port may not be allocated to the user any more.
Therefore, the same user can acquire a plurality of special ports from the cloud management platform aiming at different managed devices, and therefore the same user can simultaneously access the managed devices through the special ports.
In another embodiment, a counter may be further set in the cloud management platform, where the counter is used to record the number of times of matching failure, and when the number of times of matching failure reaches a preset value, the access request sent by the user is not processed, so as to avoid waste of resources of the cloud management platform.
To elaborate the technical solution in the present disclosure, the present disclosure further provides an embodiment, as shown in fig. 2, in this embodiment, there are 30080,30090 two dedicated ports in the port table in the cloud management platform that can be used to access the local management website.
The cloud management platform receives a request initiated by a user to the address www.cloudweb.com:80 carrying the information of the user and the information of the device 2 through the browser.
After receiving the request, the cloud management platform finds that the port is a message from 80, and queries a key1 (username + ip) in the port table, at this time, finds that there is this key1 in port 1(30080), which indicates that this port is being used by key 1. Continuing to look for data in port 2(30090), this port is found to be unused by key 1. At this point, the 30090 port is distributed to the user for accessing the locally administered web page for device 2, i.e., the device information and user information are redirected www.cloudweb.com:30090 for access. And marks this port as used by this key 1.
When the user accesses the device local management website via www.cloudweb.com:30090, the key1 information under port 2 in the port table is refreshed each time.
The disclosed embodiment further provides a network device, where the network device may be a server, a cloud management platform is operated in the network device, the cloud management platform is connected to a managed device, and the network device includes:
a receiving module, configured to receive an access request sent by a user, where the access request carries target user key information used to indicate that the user accesses a target managed device;
the first processing module is used for matching the key information of the target user with a configured port table;
the second processing module is used for judging whether an unallocated target port exists in the port table or not when the first processing module outputs a matching failure result, and if so, allocating the target port to a user;
or, when the first processing module outputs a successful matching result, it is determined that the first port for accessing the target managed device has been allocated to the user.
Optionally, the method for generating the key information of the target user includes:
and generating the target user key information according to the user information of the user and the equipment information of the target managed equipment to be accessed by the user.
Optionally, the network device further includes: a configuration module for configuring the operation of the mobile terminal,
the configuration module is used for configuring a port table in the cloud management platform, and the port table records ports which are not allocated to users and/or ports which are allocated to the users;
and corresponding to the port allocated to the user, storing user key information corresponding to the port allocated to the user.
Optionally, the first processing module is specifically configured to traverse the port table by using key information of a target user;
and if the port table does not have the user key information matched with the target user key information, the matching is considered to be failed.
