In the following embodiments, the computer device 2 will be exemplarily described as an execution subject.
Example one
Referring to fig. 1, a flowchart of steps of a method for performing a short-range handover according to an embodiment of the present invention is shown. It is to be understood that the flow charts in the embodiments of the present method are not intended to limit the order in which the steps are performed. The following description is made by taking the computer device 2 as an execution subject. The details are as follows.
And S100, generating a short connection request according to a user instruction, wherein the short connection request is used for requesting a target server to return a corresponding calling result.
When a user browses a web page through the computer device (target client) 2, the computer device 2 may generate the sms according to a script statement of the web page, an event (such as a click) triggered by the user on the web page, or a user instruction input by the user on the web page. The short connection request may be an http request, and is used to request the target server to return a corresponding call result.
Step S102, judging whether a long communication channel exists.
After obtaining the short connection request, the computer device 2 may determine whether a long connection channel exists between the long connection server and the computer device, where the long connection channel may be pre-established. The specific establishment steps of the long connecting channel are as follows.
In an exemplary embodiment, the short connection switching method may further include a step S200 to a step S202 of establishing a long connection channel, where: step S200, sending an access request to a long-connection routing server so that the long-connection routing server returns a corresponding long-connection server IP according to the access request; and step S202, establishing a long communication channel according to the long connection server IP and the corresponding long connection server.
After being started, the computer device 2 may generate an access request for accessing the long-connection routing server, and send the access request to the long-connection routing server, where the access request carries target information corresponding to the computer device 2, and the target information includes target client information associated with the computer device 2. After receiving the access request, the long-connection routing server may match a corresponding long-connection server for the computer device 2 according to the target information, and send the long-connection server IP corresponding to the long-connection server to the computer device 2. After obtaining the long connection server IP, the computer device 2 may establish a long connection channel with the corresponding long connection server according to the long connection server IP.
It should be noted that, each time the computer device 2 sends a request to the server through the http request, there are three handshakes for establishing a connection, four waving for disconnecting a connection, certificate verification, and the like, and extra time consumption is caused because the channels are not multiplexed; in order to solve these problems, the existing method switches the HTTP protocol to the websocket protocol (long link), that is, switches from the short link to the long link, when the client requests a resource from the server. The WebSocket protocol is a simple Socket simulation protocol established on the basis of Web and can be used for solving the problem that a client initiates a plurality of http requests to a server resource browser and extra time consumption is caused by long-time polling. However, most of the methods adopt a domain name connection method, and the connection method is low in power and efficiency. In order to solve the above problem, the embodiment establishes the long communication channel with the long connection server, thereby solving the problem of channel non-reuse and the problem of easily causing additional time consumption; the long connecting channel is established by the long connecting server IP and the corresponding long connecting server, so that the problems of low connecting power and low connecting efficiency are solved.
In an exemplary embodiment, the step S200 may further include a step S300 to a step S302, where: step S300, judging whether a normally running long connection server exists in a long connection server cluster associated with the long connection route server through the long connection route server; and step S302, if the long-connection server cluster has the normally running long-connection server, selecting the corresponding long-connection server from the normally running long-connection servers through the long-connection routing server according to the access request, and returning the corresponding long-connection server IP of the long-connection server.
For example, the long connection route server may pre-configure a preset load threshold for the long connection server cluster, and when a load value of a long connection server in the long connection server cluster is lower than the preset load threshold, the long connection server is a normally operating long connection server. It should be noted that the long-connection routing server may also configure preset thresholds corresponding to other parameters of the long-connection server for the long-connection server cluster, and determine whether the long-connection server is operating normally according to a plurality of preset thresholds.
After receiving the access request sent by the computer device 2, the long connection route server may determine, according to the access request, whether a long connection server that normally operates exists in a long connection server cluster currently associated with the long connection route server. If a normally-operated long connection server exists, the long connection routing server can obtain long connection server cluster information in advance according to the target information and the long connection routing server, select a corresponding long connection server from the normally-operated long connection servers for the computer equipment 2, and send a long connection server IP of the long connection server to the computer equipment 2, so that the computer equipment 2 establishes a long connection channel with the long connection server according to the long connection server IP. The long-connection routing server can acquire long-connection server cluster information in advance, wherein the long-connection server cluster information comprises information of load, fault report, double activities and the like of a long-connection server cluster; the long communication channel is used for transmitting a long connection request, namely a websocket request. In this embodiment, the transmission efficiency of the long communication channel is improved by matching the normally operating long connection server with the computer device 2.
In an exemplary embodiment, the method for short connection handover may further include steps S400 to S402, where: step S400, monitoring whether a long connection server corresponding to the IP of the long connection server normally runs or not through the long connection route server; and step S402, if the long-connection server does not normally operate, selecting a new long-connection server from the long-connection server cluster through the long-connection routing server according to the access request, and returning a new long-connection server IP corresponding to the new long-connection server.
After the computer device 2 establishes a long communication channel with the long connection server, the long connection routing server monitors whether the long connection server normally operates. For example, after the long-connection server is connected to the computer device 2, if the load of the long-connection server is too large or another fault occurs, the long-connection routing server may select a new long-connection server from the long-connection server cluster according to the access request, and return a new long-connection server IP corresponding to the new long-connection server. In this embodiment, whether the long connection server operates normally is monitored to ensure that the request sent by the computer device 2 can be transmitted normally, so as to further improve the transmission efficiency of the long connection channel.
And step S104, if the long communication channel exists, switching the short connection request into a long connection request, and sending the long connection request to a long connection server based on the long communication channel, so that the long connection server switches the long connection request into a short connection request and sends the short connection request to the target server, and the target server returns a corresponding calling result according to the short connection request.
In this embodiment, in order to solve the problem that when a request is sent to a target server through the http request, a channel is not multiplexed and additional time is consumed, the computer device 2 may switch the short connection request to the long connection request, where switching the short connection request to the long connection request means that a protocol between the computer device 2 and the server is switched from the http protocol to the websocket protocol, that is, the short connection request is switched to the long connection request. It will be appreciated that, originally, the computer device 2 only had to communicate with the target server, the short-connection request is now switched to the long-connection request, and the computer device 2 only has to communicate with the long-connection server, i.e. the computer device 2 is switched from communicating with the target server to communicating with the long-connection server.
In the embodiment, the short connection request is switched to the long connection request mode, and the computer device 2 only needs to use the http mode when communicating for the first time (sending the access request to the long connection route server), so that the time consumption is reduced; after the long communication channel is established, the processes of handshaking, certificate verification, waving hands and the like are omitted in each communication between the server and the long communication channel, and performance consumption is reduced.
In an exemplary embodiment, the step S104 may further include a step S500 to a step S504, where: 500, monitoring whether a long-connection server cluster corresponding to the long-connection server normally operates or not through the long-connection routing server; step S502, if the long-connection server group does not normally run, generating and returning degradation information through the long-connection route server; and step S504, sending the short connection request to the target server according to the degradation information, so that the target server returns a corresponding calling result according to the short connection request.
Illustratively, when all short connection requests are switched to long connection requests, the long connection routing server can monitor the long connection server cluster, so that monitoring of the buried points and performance of all data is realized; the security mechanism of the application dispersed at the back end is unified in the security specification of the long-connection routing server; the method also realizes the combing of request parameter formats, extracts common parameters as basic information, reduces flow, improves communication efficiency and the like.
When the long-connection routing server monitors that the long-connection server cluster is subjected to collective shutdown upgrading or all the long-connection servers have faults, and the like, it indicates that the long-connection server cluster does not normally operate, and in order to ensure that the service (short-connection request) of the computer equipment 2 is normally performed, the computer equipment 2 can switch the long-connection request into a short-connection request mode, that is, directly send the short-connection request to the target server, so that the target server returns a corresponding calling result according to the short-connection request.
In an exemplary embodiment, the step S104 may further include: and configuring a corresponding sequence ID for each long connection request according to the request sequence of each short connection request so that the long connection server can return a corresponding calling result according to the sequence ID.
For example, the computer device 2 may configure a corresponding sequence id (serial number) for each long connection request according to the request sequence of each short connection request, and switch the short connection request carrying the sequence id into a long connection request to be sent to the long connection server. After the long connection server obtains the long connection request, the long connection request is switched to a short connection request carrying a sequence ID, the short connection request carrying the sequence ID is sent to a target server, so that the target server returns a corresponding calling result, and after the long connection server obtains the calling result, the calling result can be sent to the computer device 2 according to the sequence ID of the calling result pair. In the prior art, a client needs to send a request a and a request B, and then the request B needs to wait for the request data and data of the request a to be returned before requesting the data. In this embodiment, the sequence id is added so that each request carries its own serial number, and when the server returns data, it can know which request data is based on the serial number and then process the data. For example, the sequence and sequence number of the request are A:1, B:2, C:3, respectively, the sequence number returned by the server is 3, 1, 2, and then the server knows that the sequence returned is C, A, B, and the data can be processed correctly.
In some embodiments, the target server configuration may also be configured in a duplex mode, so that the target server actively pushes data to the computer device 2, which saves traffic and increases efficiency. According to the embodiment, the data interaction design between the ends is more flexible through a duplex mode, and more service scenes are met.
And step S106, if the long communication channel does not exist, the short connection request is sent to the target server, so that the target server returns a corresponding calling result according to the short connection request.
For example, if the long connection channel does not exist, it indicates that the current operation of the long connection server is abnormal, for example, a long connection server cluster has a shutdown upgrade, a complete fault, and the like, and in order to ensure that the service is normally performed by the computer device 2, the computer device 2 may send the short connection request to the server in a polling manner, so that the server returns a corresponding substitute result according to the short connection request.
According to the scheme, the communication efficiency between the computer equipment 2 and the server is improved by switching short connection to long connection; the long connection channel is established, so that the long connection server has a channel and a method for uniformly controlling all requests and data, and the communication efficiency and safety are improved.
Exemplarily, the method for short-range handover further includes: and uploading the calling result to a block chain.
For example, uploading the call result to the blockchain can ensure the security and fair transparency. The blockchain referred to in this example is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, and the like. A block chain (Blockchain), which is essentially a decentralized database, is a string of data blocks associated by using a cryptographic method, and each data block contains information of a batch of network transactions, which is used for verifying the validity (anti-counterfeiting) of the information and generating a next block. The blockchain may include a blockchain underlying platform, a platform product service layer, an application service layer, and the like.
