[0029] Embodiments of the present disclosure will be described in more detail with reference to the drawings. While certain embodiments of the present disclosure will be shown and described below, it is to be understood that the present disclosure can be embodied in various forms and should not be construed as limited to the embodiments set forth herein.

[0033] It should be noted that the terms "one", "multiple" in the present disclosure are illustrative and not restrictive, and those skilled in the art should understand that "one or more" should be understood unless otherwise explicitly indicated in the context.
[0034] The names of the messages or information exchanged between the devices in the embodiments of the present disclosure are only for illustrative purposes, and are not intended to limit the scope of the messages or information.
[0035] In some large or complex application systems, connection pooling technology can be used to manage connection resources, so as to avoid the overhead of repeated connection establishment and disconnection when providing network access services, thus achieving the purpose of connection reuse. For example, proxy-based database middleware initializes a connection pool for the database cluster at startup to provide database access services.
[0036] For example, Figure 1 This is a schematic diagram of a network connection process in related technologies, such as... Figure 1 As shown, when an access request (such as a query request) arrives, the database middleware can retrieve a backend connection from the connection pool, correct the retrieved backend connection based on client variables, and return the backend connection to the connection pool after use. However, the lack of any processing on the connection upon return can lead to connection pool pollution.
[0037] To illustrate this, an example will be provided. Figure 2 This is a schematic diagram of another network connection process in related technologies, such as... Figure 2 As shown, user A can obtain connection 2 from the connection pool through client A to execute Structured Query Language (SQL), and set the system variable (Foreign_Key_Checks, FKC) for enabling and disabling foreign key constraints to 0. Then, connection 2 is returned to the connection pool, causing connection pollution. Subsequently, when user B retrieves a connection from the connection pool through client B, it may receive connection 2 that user A just returned with FKC = 0. Furthermore, user B's client variables have not been set for FKC, which may cause errors in user B's subsequent SQL execution.
[0038] To address the aforementioned technical problems, this disclosure provides a network connection processing solution, exemplarily, Figure 3 This is a scenario diagram of network connection processing provided in an embodiment of the present disclosure, such as... Figure 3 As shown, the client can send an access request to the middleware. The middleware can retrieve a network connection from the connection pool and use the network connection to execute the access operation corresponding to the access request. When the access operation ends and a connection return event for the network connection is triggered, the middleware can obtain the session variable corresponding to the network connection. If the session variable indicates that the connection variable of the network connection, which is likely to affect access, has been modified, the middleware can initialize the connection variable of the network connection and return the initialized network connection to the connection pool. This can achieve the reset of the network connection variable, effectively avoiding pollution of the connection pool and thus avoiding subsequent access errors.
[0039] In order to better understand the inventive concept of the embodiments of the present disclosure, the technical solutions of the embodiments of the present disclosure are described below in combination with exemplary embodiments.
[0040] Figure 4 A flowchart of a network connection processing method provided by the embodiments of the present disclosure is shown in FIG. 4. The method can be executed by a network connection processing apparatus. The apparatus can be implemented by software and / or hardware, and can be integrated in an electronic device, for example, a device including a middleware, such as a database middleware. Figure 3 As shown in FIG. 4, the method includes the following steps. Figure 4
[0041] In step 401, when a connection playback event for a target network connection is triggered, a target session variable corresponding to the target network connection is obtained.
[0042] The network connection can be understood as a connection saved in a connection pool of the middleware, which needs to be managed by the middleware and is used to provide a quick connection function for access.
[0043] Taking a database access scenario as an example, the middleware can be a database middleware, and the network connection processing method in the embodiments of the present disclosure can be executed by the middleware in the database middleware. The connection playback event can be an event of putting the network connection back to the connection pool. The session variable can be a variable existing only in a connection for one access between a client and a database server, and the target session variable can be a variable existing in a current connection for access between the current client and the database server based on the target network connection. Figure 3
[0044] In some embodiments of the present disclosure, when an access result is obtained after a corresponding access operation is performed based on the target network connection according to an access request sent by a target device, a connection playback event for the target network connection can be triggered. In other embodiments of the present disclosure, when a connection playback instruction for the target network connection sent by another device is received or any other preset connection playback event is triggered, the connection playback event for the target network connection can also be triggered.
[0045] Specifically, when it is determined that the connection playback event for the target network connection is triggered, the middleware can obtain the target session variable of the target network connection stored in the memory of the middleware, or call the target session variable of the target network connection stored in a background server.
[0046] In step 402, when the target session variable indicates that a target connection variable of the target network connection has been modified, the connection variable of the target network connection is initialized to obtain an initialized target network connection.
[0047] The connection variables can be variables related to network connection execution access. In the embodiments of the present disclosure, the connection variables can include at least one of a user variable, a system variable, and a library state variable. The user variable can be a user-defined variable, for example, the user variable includes query content, etc. The system variable can be understood as a variable for configuring a running environment of a service end provided by a system, for example, for a relational database management system MySQL, the variable can be a variable for configuring a running environment of a MySQL server, for example, the system variable can include a character set variable, etc. The library state variable can be used to indicate a variable of a database queried by a user, for example, the library state variable can include a database name, a database code, etc. The target connection variable refers to a current connection variable corresponding to the target network connection. The target connection variable is modified or unmodified.
[0048] In the embodiments of the present disclosure, the target connection variable can be a connection variable that is easy to affect access.
[0049] Optionally, the target connection variable can include a target sub-variable in the user variable and / or the system variable, and the target sub-variable includes a variable other than the character set variable. When the network connection is established in the connection pool initialization phase, the character set variable has been set, and the character set variable can include a client character set variable (character_set_client), a connection character set variable (character_set_connection), and a result character set variable (character_set_results), etc. The client character set variable can be used to set a character set used by a client, the connection character set variable can be used to set a character set when a database is connected, and the result character set variable can be an encoding format used by a database when a result is returned to a client.
[0050] When the target connection variable includes the target sub-variable in the user variable and the system variable, and the target sub-variable includes a variable other than the character set variable, after obtaining the target session variable corresponding to the target network connection, the method further includes: in a case where it is detected that the user variable in the target session variable is empty and all the target sub-variables in the target session variable are empty, determining that the target session variable indicates that the target connection variable of the target network connection is unmodified; and in a case where it is detected that the user variable in the target session variable is not empty and / or at least one of the target sub-variables in the target session variable is not empty, determining that the target session variable indicates that the target connection variable of the target network connection is modified.
[0051] Specifically, the middleware can determine whether the setting value of the target sub-variable and the setting value of the user variable exist in the target session variable. If any setting value of the target sub-variable, or any setting value of the user variable, or any setting value of the target sub-variable and any setting value of the user variable exist, it is determined that the target session variable indicating the target connection variable of the target network connection has been modified. Otherwise, it can be determined that the target session variable indicating the target connection variable of the target network connection has not been modified.
[0052] In this way, after obtaining the target session variable corresponding to the target network connection, the modification of the target network connection can be determined.
[0053] In the embodiment of the present disclosure, in the case where the target session variable indicates that the target connection variable of the target network connection has been modified, the connection variable of the target network connection can be initialized to obtain the initialized target network connection, that is, the connection variable of the target network connection is reset.
[0054] In step 403, the initialized target network connection is put back into the connection pool.
[0055] The connection pool can be a container for including a plurality of network connections. The connection pool can include a certain number of network connections, which are idle network connections not used for processing access requests, that is, valid network connections. In this way, when processing an access request, a network connection does not need to be created in real time, but a usable network connection can be selected from the connection pool to process the access request, thereby shortening the time required by the client to establish a network connection with the server.
[0056] Taking a database access scenario as an example, the connection pool can be a database connection pool, which is used to connect to a database.
[0057] In the embodiment of the present disclosure, after the middleware obtains the initialized target network connection, the initialized target network connection can be put back into the connection pool, thereby avoiding subsequent access errors under the premise of avoiding connection pollution.
[0058] In the embodiment of the present disclosure, when a connection return event for the target network connection is triggered, it can be determined whether the target session variable corresponding to the target network connection indicates that the target connection variable of the target network connection has been modified. If the target session variable indicates that the target connection variable of the target network connection has been modified, the connection variable of the target network connection is initialized to obtain the initialized target network connection, and the initialized target network connection is put back into the connection pool. In this way, in the process of putting the network connection back into the connection pool, in the case where the connection variable that is easy to affect access has been modified, the network connection can be reset in variable before being put back into the connection pool, thereby effectively avoiding pollution of the connection pool and further avoiding subsequent access errors.
[0059] In some embodiments of the present disclosure, after obtaining the target session variable corresponding to the target network connection, the processing method of the network connection can further include: in a case where the target session variable indicates that the target connection variable of the target network connection is not modified, returning the target network connection to the connection pool.
[0060] Specifically, when it is determined that there is at least one target sub-variable and / or user variable in the target session variable, it can be determined that the target session variable indicates that the target connection variable of the target network connection is not modified, and at this time, the target network connection can be directly returned to the connection pool.
[0061] Since the frequency of modification of the character set variable is generally small, if there is no variable other than the character set variable in the target session variable, the target network connection can be returned to the connection pool, and the effective connection of the commonly used user variable and character set variable can be retained under the premise of avoiding connection pollution, thereby increasing the reusability of the connection.
[0062] In some embodiments of the present disclosure, triggering the connection return event for the target network connection can include: receiving an access request sent by a target device, the access request carrying a target session variable; modifying a connection variable of the target network connection according to the target session variable; executing an access operation corresponding to the access request by using the target network connection; and triggering the connection return event for the target network connection when an access result corresponding to the access operation is obtained.
[0063] The target device can be an electronic device of any client. The middleware can receive an access request sent by a target device, take out a target network connection from the connection pool, modify a connection variable of the target network connection according to the target session variable in the access request, execute a corresponding access operation by using the target network connection, and after obtaining an access result corresponding to the access operation, the target network connection needs to be returned to the connection pool, that is, the connection return event for the target network connection is triggered.
[0064] In some embodiments, after receiving the access request sent by the target device, the processing method of the network connection can further include: storing the target session variable in association with the target network connection; wherein obtaining the target session variable corresponding to the target network connection includes: obtaining the target session variable stored in association with the target network connection.
[0065] Specifically, the middleware can further store the target session variable in the access request in association with the target network connection after receiving the access request sent by the target device, so that the target session variable of the target network connection stored locally can be directly obtained subsequently.
[0066] In some embodiments, after triggering the connection return event for the target network connection, the method for processing the network connection can further include: feeding back the access result to the target device.
[0067] Specifically, after triggering the connection return event for the target network connection, the middleware can perform the process of returning the target network connection to the connection pool in parallel with feeding back the access result to the target device, thereby achieving connection recycling in an asynchronous manner and avoiding network time consumption caused by variable resetting of the network connection.
[0068] Figure 5 Another flowchart of a method for processing a network connection is provided for the embodiments of the present disclosure. Based on the above embodiments, the method for processing the network connection is further described. As shown in Figure 5 The method includes:
[0069] Step 501: receiving an access request sent by a target device.
[0070] The access request carries a target session variable.
[0071] Optionally, after receiving the access request sent by the target device, the method for processing the network connection can further include: storing the target session variable in association with the target network connection.
[0072] Step 502: modifying a connection variable of the target network connection according to the target session variable.
[0073] The connection variable includes at least one of a user variable, a system variable, and a library state variable.
[0074] Step 503: performing an access operation corresponding to the access request by using the target network connection.
[0075] Step 504: triggering a connection return event for the target network connection when an access result corresponding to the access operation is obtained.
[0076] After step 504, steps 505-509 and step 510 can be performed in parallel.
[0077] Step 505: obtaining a target session variable corresponding to the target network connection.
[0078] Optionally, obtaining the target session variable corresponding to the target network connection includes: obtaining the target session variable stored in association with the target network connection.
[0079] The target connection variable is the connection variable of the target network connection. The target connection variable can include a target sub-variable in the user variable and / or the system variable. The target sub-variable includes variables other than the character set variable.
[0080] After step 505, when the target connection variable includes the target sub-variable in the user variable and the system variable, and the target sub-variable includes the variable other than the character set variable, it can be judged whether the target connection variable of the target network connection is modified through step 506.
[0081] Step 506, it is judged whether the user variable in the target session variable is empty and whether the target sub-variable in the target session variable is empty, if yes, step 507 is executed; otherwise, step 509 is executed.
[0082] Step 507, it is determined that the target session variable indicates that the target connection variable of the target network connection is not modified, the connection variable of the target network connection is initialized, and the initialized target network connection is obtained.
[0083] Step 508, the initialized target network connection is put back to the connection pool.
[0084] Step 509, it is determined that the target session variable indicates that the target connection variable of the target network connection is not modified, and the target network connection is put back to the connection pool.
[0085] Step 510, the access result is fed back to the target device.
[0086] In the embodiment of the present disclosure, when the access result is obtained after the corresponding access operation is performed on the target network connection based on the access request sent by the target device, the connection return event for the target network connection can be triggered, and then the target network connection can be put back to the connection pool and the access result can be fed back to the target device in an asynchronous manner. In the process of putting the network connection back to the connection pool, in the case where it is determined that the connection variable that is easy to affect the access has been modified, the network connection can be reset in variables before being put back to the connection pool, which effectively avoids the pollution to the connection pool and further avoids triggering the subsequent access error; and in the case where it is determined that the connection variable that is easy to affect the access has not been modified, the effective connection of the commonly used user variable and the character set variable can be preserved, and the reusability of the connection is increased; at the same time, the connection recycling can be performed in an asynchronous manner, which avoids the network time consumption caused by the variable reset of the network connection.
[0087] An exemplary network connection processing schematic diagram provided by the embodiment of the present disclosure is shown in FIG. 1. Figure 6 As shown in FIG. 1, compared with the prior art, Figure 6 the embodiment of the present disclosure can effectively avoid the pollution to the connection pool caused by the variable reset of the network connection, and further avoid triggering the subsequent access error. Figure 2The processing scheme of the network connection in the embodiment of the present disclosure increases the judgment of whether the user variable in the session variable of the current network connection is empty and whether only the character set variable is contained in the system variable in the process of putting the connection back to the connection pool. If yes, the network connection is directly put back to the connection pool. Otherwise, the current network connection is reset and then put back to the connection pool. That is, whether any system variable or any user variable except the character set variable has a set value in the session variable of the current network connection is judged. If yes, the current network connection is reset and then put back to the connection pool. Otherwise, the network connection is directly put back to the connection pool. In this way, whether the network connection is reset is determined by checking the content of the system variable of the network connection when the network connection is recycled, so as to maximize the reusability of the connection under the premise of avoiding connection pollution.
[0088] Meanwhile, as shown in Figure 6 , the connection recycling can be performed in an asynchronous manner according to the following steps: 1, returning a client response result; 2, performing initialization (reset connection) on the current network connection; 3, putting the current network connection back to the connection pool. By using the asynchronous recycling manner in the recycling stage of the network connection, the network time consumption of the Round-Trip Time (RTT) possibly introduced in the previous step for the query process is avoided.
[0089] In summary, in the embodiment of the present disclosure, the problem of connection pool pollution can be solved, the pollution to the connection pool is effectively avoided, and the subsequent access error is further avoided; and the effective connection of the commonly used user variable and character set variable is preserved, the reusability of the connection is improved; meanwhile, the connection recycling is performed in an asynchronous manner, and the network time consumption caused by the variable reset of the network connection possibly introduced is avoided.
