Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Example one
Referring to fig. 1, a flowchart illustrating steps of a method for notifying a user of an online/offline status according to a first embodiment of the present invention is shown. The method of the embodiment may include the steps of:
At present, most of service statistical data are completed by depending on dotting of a browser end, namely, the browser sends dotting data to a server by initiating a dotting request, and the server records the dotting data. The dotting data is service data of the function point, for example, when a user clicks a link on a web page, the click information of the link is the dotting data.
In this embodiment, the dotting data may be heartbeat information sent by the user, where the heartbeat information of the user is sent every preset time (for example, 10 s) for each online user. The dotting data may include a dotting user identifier of a user who sends the dotting data, and when the dotting data is received, the online deadline corresponding to the dotting user identifier is set.
And 102, if the user corresponding to the dotting user identification is judged to be online for the first time, sending an online notification of the user corresponding to the dotting user identification.
When receiving the dotting data, judging whether the user corresponding to the dotting user identification is on-line for the first time or not so as to determine whether on-line notification of the user corresponding to the dotting user identification needs to be sent or not, and if the user corresponding to the dotting user identification is on-line for the first time, sending the on-line notification of the user corresponding to the dotting user identification.
It should be noted that, in the above step 101, the process of setting the online deadline time corresponding to the dotting user identifier is not strictly ordered to the process of sending the online notification of the user corresponding to the dotting user identifier if it is determined that the user corresponding to the dotting user identifier is online for the first time in step 102, and both the processes are executed when the dotting data is received, and may be executed sequentially or simultaneously.
And 103, sequencing all the stored user identifications according to the corresponding online deadline.
And each stored user identifier corresponds to an online deadline, and all the stored user identifiers are sorted according to the corresponding online deadline. The sorting may be ascending sorting or descending sorting, which is not limited in this embodiment.
It should be noted that, the foregoing steps 101, 102 and 103 are not strictly ordered, and are all executed when the conditions are satisfied. For example, step 101 and step 102 are executed when dotting data is received, step 103 may be executed after step 101, or after step 102, or may be executed according to a set condition, such as real-time execution, or executed according to a set time interval (e.g., step 102 is executed every 30 s), and the like, which is not limited in this embodiment of the present invention.
And step 104, sequentially judging whether the online deadline corresponding to the current user identifier is reached according to the sequencing sequence for all the user identifiers after sequencing, and stopping judging until the online deadline corresponding to a certain user identifier is not reached.
In the process, the user identification of which the online deadline is reached is only needed to be judged, and the user identification of which the rest online deadline is not reached is not needed to be judged again, so that all the user identifications are not needed to be inquired, only part of the user identifications are needed to be judged, and the inquiry amount is greatly reduced.
And 105, sending an offline notification of a user corresponding to the user identifier aiming at the user identifier of which the corresponding online deadline is reached.
According to the determination result in step 104, for the user identifier whose corresponding online deadline has been reached, it may be determined that the user corresponding to the user identifier has been offline, and therefore, an offline notification may be sent for the user who has been offline.
According to the embodiment of the invention, all the user identifications do not need to be inquired one by one, and only part of the sorted user identifications need to be judged, so that the inquiry quantity is small, and the online and offline conditions of the user can be informed in a more timely manner.
Example two
Referring to fig. 2, a flowchart illustrating steps of a method for notifying a user of an online/offline status according to a second embodiment of the present invention is shown. The method of the embodiment may include the steps of:
In this embodiment, the receiving thread is configured to receive dotting data sent by a user, the processing thread is configured to execute subsequent processing, the receiving thread and the processing thread can communicate with each other, and the receiving thread sends the dotting data to the processing thread when receiving the dotting data.
Preferably, when the receiving thread receives the dotting data in step 201, the process of sending the dotting data to the processing thread may include: and when receiving the dotting data, the receiving thread sends the dotting data to the processing thread according to a User Datagram Protocol (UDP). And the data transmission is carried out according to the UDP, so that the internal data transmission efficiency can be effectively improved.
Preferably, when the receiving thread receives the dotting data in step 201, the process of sending the dotting data to the processing thread may be completed by the Nginx server. The Nginx is a lightweight Web server, a reverse proxy server, and an email (IMAP/POP3) proxy server, and the performance of the Nginx server is high, and the processing efficiency can be improved.
The dotting data comprises a dotting user identifier, and the processing thread sets the online deadline corresponding to the dotting user identifier after receiving the dotting data.
Preferably, this step 202 may comprise the following sub-steps:
sub-step a1, determining whether the dotting user identification has been saved. If yes, perform substep a2, otherwise perform substep a 3.
And a substep a2, updating the online deadline corresponding to the dotting user identifier to a time obtained by adding the set time to the current time.
And a substep a3, storing the dotting user identifier, and setting the online deadline corresponding to the dotting user identifier as the time obtained by adding the current time to the set time.
When a certain user is online, the user identifier of the user is stored in the server, that is, the user identifier of the user who is online before is stored in the server. Each user identification is corresponding to an online deadline, and the online deadline indicates that the user corresponding to the user identification is considered to be offline after the online deadline is reached. Preferably, in this embodiment, a hash table may be used to establish a corresponding relationship between the user identifier and the online deadline, so that a faster query can be implemented.
After receiving the dotting data, the processing thread determines whether the dotting user identification is stored or not so as to determine whether the user corresponding to the dotting user identification sends the dotting data for the first time (that is, whether the user is not on line before), and if the dotting user identification is stored, the online deadline time corresponding to the dotting user identification can be directly updated to the time obtained by adding the set time to the current time; if the dotting user identifier is not stored, the dotting user identifier is stored firstly (namely, the dotting user identifier is added in the server to indicate that the user is online), and the online deadline time corresponding to the dotting user identifier is set as the time obtained by adding the set time to the current time. For the setting time, a person skilled in the art may select any suitable value according to practical experience, for example, the setting time may be set to 30s, 1min, and the like, and the specific value is not limited in this embodiment.
And 203, if the processing thread judges that the user corresponding to the dotting user identification is online for the first time, sending an online notification of the user corresponding to the dotting user identification.
The processing thread judges whether the user corresponding to the dotting user identification is online for the first time, if the user corresponding to the dotting user identification is online for the first time, the processing thread can send an online notification of the user corresponding to the dotting user identification to the user online and offline event interface, and the online condition of the user can be known in time by sending the online notification of the user.
Preferably, this step 203 may comprise: determining whether the dotting user identification is saved; if so, judging that the user corresponding to the dotting user identification is online for the first time, and sending an online notification of the user corresponding to the dotting user identification, otherwise, not processing, namely, not sending the online notification of the user corresponding to the dotting user identification.
It should be noted that, in this embodiment, the order of executing step 202 and step 203 is not limited, step 202 may be executed first and then step 203 may be executed, step 203 may be executed first and then step 202 may be executed, or step 202 and step 203 may be executed concurrently.
And step 204, sequencing all the stored user identifications by the processing thread according to the corresponding online deadline.
The sorting may be ascending sorting according to the online deadline, or descending sorting according to the online deadline, which is not limited in this embodiment.
And step 205, the processing thread sequentially judges whether the online deadline corresponding to the current user identifier has arrived according to the sorting order for all the user identifiers after sorting, and stops judging until the online deadline corresponding to a certain user identifier does not arrive.
Preferably, this step 205 may comprise: and for all the sorted user identifications, sequentially judging whether the online deadline corresponding to the current user identification is earlier than the current time or not from the user identification with the earliest online deadline according to the sorting sequence, and stopping judging until the online deadline corresponding to a certain user identification is equal to or later than the current time.
In this embodiment, the determination is started from the user identifier with the earliest corresponding online deadline, and if the online deadline corresponding to the user identifier is earlier than the current time, it is determined that the online deadline has reached, that is, the user corresponding to the user identifier may have been offline, and at this time, the determination is continued for the next user identifier; if the online deadline corresponding to the user identifier is equal to or later than the current time, determining that the online deadline has not arrived, that is, the user corresponding to the user identifier has not been offline, and at this time, because the online deadline corresponding to the user identifier below the user identifier is later than the online deadline corresponding to the user identifier, directly determining that the online deadline corresponding to the user identifier below the user identifier has not arrived, that is, the user corresponding to the user identifier below the user identifier has not been offline, and thus, no further determination is needed.
In step 206, the processing thread sends an offline notification of the user corresponding to the user identifier for which the corresponding online deadline has been reached.
After the determination in step 205, the processing thread may obtain the user identifiers whose corresponding online deadline has been reached according to the determination result, and determine that the users corresponding to the user identifiers have been offline, so that the processing thread may send an offline notification of the user corresponding to the user identifier to the user offline event interface for the user identifier whose corresponding online deadline has been reached. By sending the offline notification of the user, the offline condition of the user can be known in time.
Preferably, in this embodiment, after the step 205, the method may further include: and the processing thread counts the number of the online users according to the judgment result. After the determination in step 205, the number of online users may be counted according to the determination result, and the counting process may specifically include: the processing thread determines the number of user identifications for which the corresponding online expiration time has been reached, and takes this number as the number of online users. By counting the number of online users, the current burden condition of the website can be known in time, and the website is convenient to maintain and upgrade.
According to the embodiment of the invention, all the user identifications do not need to be inquired one by one, and only part of the sorted user identifications need to be judged, so that the inquiry quantity is small, and the online and offline conditions of the user can be informed in a more timely manner.
EXAMPLE III

In this embodiment, the user identifier may be divided into a plurality of groups according to a set manner, and for a specific division manner, a person skilled in the art may select any suitable manner according to actual experience, which is not limited in this embodiment of the present invention. For example, the user identities 1-10000 can be divided into a group, the user identities 10001-20000 can be divided into a group, and so on.
For each group of subscriber identities, a corresponding independent processing thread may be created, which is mainly used for processing events related to the corresponding group of subscriber identities.
When receiving dotting data comprising a dotting user identifier, firstly determining a group to which the dotting user identifier belongs, and after determining, forwarding the dotting data to an independent processing thread corresponding to the dotting user identifier, namely a corresponding independent processing thread created for the user identifier in the group to which the dotting user identifier belongs.
After receiving the dotting data, the independent processing thread corresponding to the dotting user identifier may set the online deadline corresponding to the dotting user identifier, and for a specific process of setting the online deadline corresponding to the dotting user identifier, reference may be made to the related description of step 202 in the second embodiment, which is not discussed in detail herein in this embodiment.
And 304, when the independent processing thread corresponding to the dotting user identifier judges that the user corresponding to the dotting user identifier is the first online user, sending an online notification of the user corresponding to the dotting user identifier.
For the specific process of step 304, reference may be made to the related description of step 203 in the second embodiment, and this embodiment will not be discussed in detail here.

For the sorting process of each independent processing thread, reference may be made to the related description of step 204 in the second embodiment, and this embodiment will not be discussed in detail here.
And step 306, sequentially judging whether the online deadline corresponding to the current user identifier is reached or not by the respective corresponding independent processing thread according to the sorting sequence aiming at each group of sorted user identifiers, and stopping judging until the online deadline corresponding to a certain user identifier is not reached.
For the determination process of each independent processing thread, reference may be made to the related description of step 205 in the second embodiment, and details of the determination process are not discussed here.
Preferably, in this embodiment, after the step 306, the method may further include: and counting the number of the group of online users by the corresponding independent processing threads according to the respective judgment results aiming at each group of sequenced user identifications, and determining the number of all online users according to the counting results of the independent threads. After each independent processing thread obtains its own statistical result (that is, the number of online users in a group of user identifiers corresponding to each independent processing thread), the statistical results of each independent processing thread are added, and the result obtained after the addition is the number of all online users.
In this embodiment, the user identifier is divided into a plurality of groups, and a plurality of independent processing threads are set to respectively process the related processes of the plurality of groups, so that the processing of the dotting data is more timely, and the QPS that can be assumed is higher.
