Fig. 1 is an application scenario diagram of the network connection method provided in the present application. As shown in fig. 1, includes: the system comprises terminal equipment, access equipment, portal server and authentication server, wherein the terminal equipment is provided with a client and a browser. When a user accesses internet resources by using a client, a message for accessing the internet resources is received by the access equipment, and whether the user passes authentication is judged. If the authentication is not passed or not performed, the message is forwarded to a portal server, and the portal server returns an authentication page link to the client so that the client accesses the authentication page link through a browser to obtain an authentication page. The user can input authentication information on the authentication page and send the authentication information to the access equipment, the access equipment sends the authentication information to the authentication server, the authentication server authenticates the authentication information, and the user is on-line when the authentication is passed.
After the user is online, the user is abnormally offline because the user does not access other resources in the internet through a browser for a long time or because of factors such as network instability and the like. In order to avoid the tedious operation caused by the fact that a user needs to manually input authentication information to re-authenticate after being abnormally offline, the embodiment of the application provides a network connection method to achieve authentication reconnection under the condition that the user does not perceive.
Referring to fig. 2, fig. 2 is a flowchart of a network connection method according to an embodiment of the present disclosure. The network connection method can be applied to a client that can access resources in the internet through a browser.
As shown in fig. 2, the process may include the following steps:
step 101, when a local browser determines that authentication reconnection is needed, acquiring stored authentication information through the browser; the authentication information is carried in an authentication message sent to an authentication server by the client through the browser;
as an example, the local browser may be a browser built in the client, or may be another browser installed on the terminal device where the client is located.
As one example, there are multiple implementations of determining, by a local browser, that authentication reconnects are required. One of which is shown in fig. 3 and will be described in detail below, and will not be described again here.
As one example, there are a number of implementations of stored authentication information. As one implementation manner, the stored authentication information may be acquired from an authentication packet obtained when the client detects that the browser constructs the authentication packet. As another implementation, the stored authentication information may also be authentication information obtained by means of a cookie. In specific implementation, a corresponding script file may be preset in the browser, and after it is determined that the browser has constructed the authentication message, the script may be executed to obtain the authentication information in the authentication message, and store the authentication information in a preset specified location. And meanwhile, generating a callback function for acquiring the authentication information at the specified position according to the specified position so as to execute when the subsequent browser needs to acquire the authentication information.
As one example, there are various implementations of obtaining stored authentication information through the browser. One of which is shown in fig. 4 and will be described in detail below, and will not be described again here.
And step 102, constructing an authentication message carrying the authentication information through the browser and sending the authentication message to the authentication server so as to establish connection between the browser and the authentication server according to a websocket mode when the authentication is passed.
As an example, after the authentication information is obtained through the browser, an authentication message may be constructed by the browser using the authentication information and sent to the authentication server. Since the authentication information is carried in the authentication message sent by the client to the authentication server through the browser, the authentication information is inevitably authenticated by the authentication server on the premise that the authentication process is not changed and the service link is not changed by the authentication service.
This completes the description of the embodiment shown in fig. 2.
According to the technical scheme, when the local browser determines that authentication reconnection is needed, the authentication message does not need to be sent to the authentication server again by manually inputting authentication information by a user, but the stored authentication information is directly acquired by the browser to construct the authentication message, and the authentication message is sent to the authentication server to complete authentication, so that the authentication reconnection without perception of the user is realized.
How to determine that the authentication reconnection is required through the local browser in step 101 will be described below with reference to the embodiment shown in fig. 3. As shown in fig. 3, the process includes:
step 1011, sending a keep-alive message to the authentication server according to the established websocket connection;
as an example, an established websocket connection is established after a previous authentication pass. Compared with http connection, websocket connection does not need to establish connection for each message once when the websocket connection sends the message. Therefore, a large number of connection establishment steps can be reduced by sending the keep-alive messages through the websocket connection, and a large number of equipment resources are saved.
Step 1012, when it is determined that the browser receives the reset connection message sent by the authentication server, it is determined that authentication reconnection is required.
As an example, the reset connection message is sent by the authentication server in response to the keep-alive message when the authentication server has closed the websocket connection but the browser has not closed the websocket connection. The authentication server closes the websocket connection, which means that the client has not transmitted the keep-alive message with the authentication server for a long time, so that the authentication server considers that the user is offline. However, the browser does not close the websocket connection, which means that the transmission of the keep-alive message with the authentication server for a long time is caused by other abnormal conditions, and therefore, when the reset connection message is received, it can be determined that authentication reconnection is needed.
As an example, when identifying whether the message is a reset connection message, the determination may be made according to a field carried in the message.
This completes the description of the embodiment shown in fig. 3.
According to the technical scheme, the websocket connection is long connection, so that in the process of sending the keep-alive messages to the authentication server through the websocket connection, the embodiment of the application can send the keep-alive messages by using the websocket connection only once by establishing the websocket connection.
After the authentication message carrying the authentication information is constructed by the browser and sent to the authentication server, if the port of the authentication service is changed, the authentication server is caused to always send the reset connection message to the browser. In order to avoid that the reconnection cannot be authenticated for a long time due to the above situation, the method performs the operation of acquiring the stored authentication information through the browser only when the number of the received reset connection messages is smaller than the message number threshold, which is described in detail below with reference to the flow shown in fig. 4:
step 1013, counting the number of the messages receiving the reset connection message in a unit time length to obtain a counting result;
as an example, the unit time length may be set in advance by the user, for example, to 3 seconds or 4 seconds or the like. The actual value of the unit time length is not specifically limited in the present application.
Step 1014, when the statistical result is smaller than a preset message quantity threshold value, acquiring the stored authentication information through the browser;
as an example, the message number threshold may be preset by the user, for example, set to 10 or 15, etc. The actual value of the message quantity threshold value is not specifically limited in the application.
As an example, if the statistical result is smaller than the preset message number threshold, it indicates that the number of times of attempting authentication reconnection is still within the normal range, and the browser still has a possibility of establishing a connection with the authentication server.
Step 1015, when the statistical result is greater than or equal to the preset message quantity threshold, outputting a prompt message, where the prompt message is used to indicate that the connection between the browser and the authentication server has been disconnected.
As an example, when the statistical result reaches the message number threshold, it indicates that the number of times of attempting authentication reconnection is enough, and the authentication reconnection can no longer be implemented, and at this time, it is no longer necessary to perform the acquisition of the stored authentication information by the browser.
As an example, after the operation of constructing the authentication packet carrying the authentication information by the browser and sending the authentication packet to the authentication server is stopped, a prompt message may be displayed on the client or the browser interface to remind a user corresponding to the client that the user needs to manually access the internet resource, the authentication information is manually sent to the authentication server through the authentication page to obtain a modified port of the authentication server, and the network connection method of the present application is continuously executed.
This completes the description of the embodiment shown in fig. 4.
Two implementation manners of performing offline detection on a user corresponding to the client according to websocket connection are respectively described below with reference to two embodiments shown in fig. 5 and fig. 6.
The following description will be made of the flow shown in fig. 5, which includes:
step 1021, sending an offline request to an authentication server through the browser by utilizing websocket connection;
as an example, when the user wishes to actively go offline, an offline request may be sent to the authentication server through the browser by using the websocket connection, so as to request the authentication server to take the user corresponding to the client offline.
Step 1022, if it is determined that the browser receives the successful offline message sent by the authentication server through the websocket connection, it is determined that the user corresponding to the client is actively offline.
As an example, if the authentication server receives the offline request and successfully takes the user corresponding to the client offline, the authentication server sends a successful offline message to the browser and closes the websocket connection. Therefore, if it is determined that the browser receives the offline message successfully through the websocket connection, it indicates that the user corresponding to the client is actively offline.
As an example, when it is determined that the user corresponding to the client is actively offline, since message interaction with the authentication server is no longer required, the websocket connection may be closed.
This completes the description of the embodiment shown in fig. 5.
Next, another implementation manner for performing offline detection on a user corresponding to the client according to websocket connection is described with reference to the flow shown in fig. 6.
As shown in fig. 6, the process may include:
step 1023, sending a keep-alive message to an authentication server by the browser through websocket connection;
as an example, keep-alive messages may be periodically sent to the authentication server, and whether the user corresponding to the client is offline is detected.
Step 1024, if it is determined that the browser receives the reset connection message sent by the authentication server, it is determined that the user corresponding to the client is abnormally offline.
As an example, the reset connection message is sent by the authentication server in response to the keep-alive message when the authentication server has closed the websocket connection but the browser has not closed the websocket connection. The authentication server closes the websocket connection, which means that the client has not transmitted the keep-alive message with the authentication server for a long time, so that the authentication server considers that the user is offline. However, since the browser does not close the websocket connection, this means that the transmission of the keep-alive message with the authentication server for a long time is caused by other abnormal conditions, and therefore, when it is determined that the browser receives the reset connection message, it can be determined that the user is abnormally offline.
This completes the description of the embodiment shown in fig. 6.
Besides the two implementation manners of performing offline detection on the user corresponding to the client shown in fig. 5 and fig. 6, the present application also provides another implementation manner:
if the browser is determined to receive the user offline message actively sent by the authentication server through the connection, determining that the user corresponding to the client side is passively offline;
as an example, if the server desires that the user corresponding to the client is offline, the server sends a user offline message to the browser to notify that the user corresponding to the client is offline.
Examples
The present application is described below in accordance with one of its embodiments. As shown in fig. 7, this embodiment includes the following flow:
step 10, when the browser establishes connection with the authentication server for the first time, the user manually inputs and stores authentication information; sending the authentication information to an authentication server through a browser, and establishing connection between the browser and the authentication server according to a websocket mode when the authentication is passed;
as an example, when the client accesses the internet resource through the browser, a message for accessing the internet resource is first sent to the access device. Because the user corresponding to the client does not complete authentication, the access device sends the message to the portal server, and the portal server returns an authentication page link to the client. When the client determines that the browser receives the authentication information input by the user on the authentication page, the authentication information is stored to the designated position for use in subsequent authentication reconnection. The browser sends an authentication message carrying the authentication information to an authentication server, and when the authentication is passed, the browser establishes connection with the authentication server according to a websocket mode.
Step 20, sending a keep-alive message to the authentication server according to the established websocket connection;
as an example, after establishing the websocket connection, the client periodically sends a keep-alive message to the authentication server through the browser, so that the user corresponding to the client maintains an online state.
Step 30, when determining that the browser receives the reset connection message sent by the authentication server, determining that authentication reconnection is needed; counting the number of the messages receiving the reset connection message in unit time length to obtain a counting result;
as an example, when the network environment of the client is poor, the keep-alive message cannot be sent to the authentication server, and the authentication server goes off-line with the user corresponding to the client. When the network environment of the client side is recovered to be normal, the keep-alive message can be successfully sent to the authentication server. However, since the authentication server has taken the user corresponding to the client offline and correspondingly closed the websocket connection on the authentication server side, the authentication server may send a reset connection packet to the browser after receiving the keep-alive packet. Once the browser receives the reset connection message, the number of messages receiving the reset connection message in unit time length is counted, and the counted result is increased by 1 when each reset connection message is received.
Step 40, judging whether the statistical result is larger than a preset message quantity threshold value or not; if the value is less than the predetermined value, the process goes to step 50, and if the value is greater than or equal to the predetermined value, the process goes to step 60.
As an example, it may be determined whether the statistical result is greater than a preset message quantity threshold value in real time.
Step 50, obtaining stored authentication information through the browser; the authentication information is carried in an authentication message sent to an authentication server by the client through the browser; constructing an authentication message carrying the authentication information through the browser and sending the authentication message to the authentication server so as to establish connection between the browser and the authentication server according to a websocket mode when the authentication is passed; and carrying out off-line detection on the user corresponding to the client according to the connection.
As an example, after establishing a websocket connection between a browser and an authentication server, a keep-alive message may be sent to the authentication server by using the websocket connection, so as to detect whether a user corresponding to the client is abnormally offline.
And step 60, outputting prompt information, wherein the prompt information is used for indicating that the connection between the browser and the authentication server is disconnected.
As an example, a prompt message may be displayed on a client or a browser interface to remind a user corresponding to the client that the user needs to manually access internet resources, and the authentication information is manually sent to the authentication server through the authentication page to obtain a port modified by the authentication server, so as to continue to execute the network connection method of the present application.
