[0028] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] Figure 1 An exemplary system architecture 100 is shown, in which embodiments of the method or apparatus for outputting information of this application may be applied.

[0031] like Figure 1 As shown, system architecture 100 may include terminal devices 101, 102, and 103, a network 104, and a server 105. Network 104 serves as the medium for providing communication links between terminal devices 101, 102, and 103 and server 105. Network 104 may include various connection types, such as wired or wireless communication links, or fiber optic cables, etc.

[0032] Users can use terminal devices 101, 102, and 103 to interact with server 105 via network 104 to receive or send messages. For example, users can send query requests to server 105 or receive query results from server 105 using terminal devices 101, 102, and 103. Various communication client applications can be installed on terminal devices 101, 102, and 103, such as web browser applications, shopping applications, search applications, instant messaging tools, email clients, and social media platforms.

[0033] Terminal devices 101, 102, and 103 can be either hardware or software. When terminal devices 101, 102, and 103 are hardware, they can be various electronic devices with a display screen and supporting web browsing, including but not limited to smartphones, tablets, e-book readers, laptops, and desktop computers. When terminal devices 101, 102, and 103 are software, they can be installed in the aforementioned electronic devices. They can be implemented as multiple software programs or software modules (e.g., to provide distributed services) or as a single software program or software module. No specific limitations are imposed here.

[0034] Server 105 can be a server that provides various services, such as a backend server that supports queries on storage space usage. The backend server can analyze and process the received query requests and other data, and feed back the processing results (such as query results) to terminal devices 101, 102, and 103.

[0035] It should be noted that a server can be either hardware or software. When the server is hardware, it can be implemented as a distributed server cluster consisting of multiple servers, or as a single server. When the server is software, it can be implemented as multiple software programs or software modules (e.g., used to provide distributed services), or as a single software program or software module. No specific limitations are made here.

[0036] It should be noted that the method for outputting information provided in the embodiments of this application is generally executed by the server 105, and correspondingly, the device for outputting information is generally located in the server 105.

[0037] It should be understood that Figure 1 The number of terminal devices, networks, and servers shown is merely illustrative. Depending on implementation needs, any number of terminal devices, networks, and servers can be included.

[0038] Continue to refer to Figure 2 The diagram illustrates a flow 200 of an embodiment of a method for outputting information according to this application. The method for outputting information according to this embodiment includes the following steps:

[0039] Step 201: Obtain the user's user identifier.

[0040] In this embodiment, the execution entity of the method for outputting information (e.g. Figure 1 The server 105 shown can be connected via a wired or wireless connection from the user's terminal device (e.g., Figure 1 The user's identifier is obtained at the terminal devices 101, 102, and 103 shown. Specifically, the executing entity can provide a query port, which the user can call to send a query request to the executing entity. The query request includes the user identifier. It is understood that the user can first send a storage space request to the executing entity to request storage space.

[0041] It should be noted that the aforementioned wireless connection methods may include, but are not limited to, 3G / 4G connection, WiFi connection, Bluetooth connection, WiMAX connection, Zigbee connection, UWB (ultra wideband) connection, and other currently known or future wireless connection methods.

[0042] Step 202: Determine the storage space requested by the user and the current usage information corresponding to the user identifier based on the user identifier.

[0043] After obtaining the user identifier, the executing entity can determine the storage space requested by the user based on the user identifier. Specifically, the executing entity locally stores the mapping between user identifiers and storage space information. Then, the executing entity can query the above mapping to determine the storage space information corresponding to the user identifier. The storage space information is used to represent the capacity of the storage space requested by the user. The executing entity can also query the current usage information corresponding to the user identifier. Here, the current usage information is the amount of storage space already used by the user.

[0044] Step 203: Determine whether there is a storage anomaly based on the storage space information and the current usage information.

[0045] After determining the storage space information corresponding to the user identifier and the current usage information, the executing entity can determine whether there is a storage anomaly. For example, the executing entity can calculate the ratio of current usage to storage space to determine whether the storage space utilization rate exceeds a first preset threshold. If it does, the storage is considered abnormal. The aforementioned first preset threshold can be set by the user or by the executing entity based on the size of the storage space.

[0046] Step 204: In response to determining a storage exception, generate and output exception information.

[0047] If the executing entity determines a storage anomaly, it can generate an anomaly message. Specifically, the executing entity can use storage space information and current usage information as the anomaly message. Alternatively, the executing entity can also generate an anomaly message based on the current storage space usage rate. This anomaly message can then be output to the user.

[0048] In some optional implementations of this embodiment, the above method may further include Figure 2 The following steps, not shown in the diagram, are: labeling the time for the acquired current usage information; and storing the labeled current usage information.

[0049] In this implementation, the executing entity can annotate the current usage information with a time stamp each time it obtains the current usage information. The annotated time is the moment the current usage information was obtained. After annotation, the executing entity can store the annotated current usage information in the database.

[0050] In some optional implementations of this embodiment, step 204 can be specifically implemented by... Figure 2The following steps, not shown, are used to achieve the following: in response to determining a storage exception, generating exception information, and outputting exception information based on the contact information submitted by the user.

[0051] In this implementation, after the executing entity determines the storage exception and generates exception information, it can send the exception information out according to the contact information submitted by the user so that the user can view it in a timely manner.

[0052] In some optional implementations of this embodiment, the above method may further include Figure 2 The following steps, not shown: In response to receiving modification information sent by the user, modify the contact information and / or the first preset threshold according to the modification information.

[0053] In this implementation, the user can send modification information to the executing entity through a port provided by the executing entity. This modification information can be used to modify the user's contact information. If the first preset threshold is set by the user, the user can also modify the first preset threshold by sending modification information. After receiving the modification information, the executing entity can modify the contact information and / or the first preset threshold.

[0054] See also Figure 3 , Figure 3 This is a schematic diagram illustrating an application scenario of the method for outputting information according to this embodiment. Figure 3 In this application scenario, after requesting 1GB of storage space, users can check their storage usage via the "Query My Storage Space" function on their mobile phone. The server, based on the user's identifier, determines that the user's storage space is 256GB, and the current usage is 200GB. If the server determines that the usage exceeds the threshold, it generates an error message: "Your storage space is 256GB, and 200GB has been used. The remaining storage space is insufficient; please request new storage space promptly." Users can then request new storage space based on this error message.

[0055] The method for outputting information provided in the above embodiments of this application first obtains the user's user identifier. Based on the user identifier, it determines the storage space requested by the user and the current usage information corresponding to the user identifier. Based on the storage space information and the current usage information, it determines whether there is a storage anomaly. If a storage anomaly is found, an anomaly message is generated and output. The method of this embodiment can achieve automatic early warning of the user's storage capacity.

[0056] See also Figure 4 This illustrates a flow 400 of an embodiment of a method for outputting information according to this application, specifically for determining a storage exception. Figure 4As shown, in this embodiment, the following steps can be used to determine whether a storage anomaly has occurred:

[0057] Step 401: Determine the current utilization rate of the storage space based on the storage space information and the current usage information.

[0058] In this embodiment, the executing entity can calculate the ratio of current usage to storage space, which is the current utilization rate of storage space.

[0059] Step 402: Determine whether the current usage rate is greater than the first preset threshold.

[0060] If the value is greater than the value, a storage error is confirmed. If the value is not greater than the value, proceed to step 403.

[0061] Step 403: Obtain historical usage information.

[0062] In this embodiment, the executing entity can obtain historical usage information from the database. It is understood that after obtaining current usage information and annotating the time each time, the executing entity can store the annotated current usage information in the database for use as historical usage information during analysis.

[0063] Step 404: Determine the rate of change in storage space usage based on historical usage information.

[0064] After obtaining historical usage information, the executing entity can plot a curve showing the change in historical usage over time. The slope of this curve can then be calculated. This slope can be used as the rate of change in storage space usage.

[0065] Step 405: Determine whether the absolute value of the rate of change in usage is greater than the second preset threshold.

[0066] If the value is greater than the given value, it indicates that the storage space is increasing or decreasing too rapidly, and there is a high probability that the storage space is abnormal. In this case, the executing entity can determine that there is a storage abnormality.

[0067] Step 406: Determine the storage space usage change curve based on historical usage information.

[0068] After obtaining historical usage information, the executing entity can also perform this step, which uses historical usage information as the vertical axis and time as the horizontal axis, thereby determining the usage change curve of storage space.

[0069] Step 407: Determine the storage space usage change cycle based on the usage change curve.

[0070] Based on the aforementioned usage change curves, the executing entity can analyze the patterns in these curves to determine the storage space usage change cycle. For some users, their storage space usage changes follow a time-based pattern. For example, at the start of a project, storage space usage gradually increases, reaching its maximum at the end of the project. Before starting the next project, all data from the previous project is deleted, allowing data for the next project to be stored in the storage space. Based on this pattern, the executing entity can determine the storage space usage change cycle.

[0071] Step 408: Determine whether the usage change curve of the current usage information period matches the usage change curve within the usage change period.

[0072] After determining the usage change cycle, the executing entity can divide the aforementioned usage change curve into multiple usage change sub-curves according to the usage change cycle. Then, it checks whether the usage change sub-curve of the current usage information's cycle matches the usage change sub-curves of other usage change cycles. If they do not match, a storage anomaly is identified. Matching here does not mean that the current usage is the same as a historical usage in another cycle, but rather that the trend of the usage change sub-curve in the current usage cycle is the same as the trend of the usage change sub-curves in other usage change cycles; for example, both showing a slow increase.

[0073] Step 409: In response to determining a storage exception, generate and output exception information.

[0074] The method for outputting information provided in the above embodiments of this application can analyze whether a user's storage space has experienced storage anomalies from multiple perspectives, thereby enabling multi-faceted early warning.
