Description
Technical Field
The present invention relates to the field of computer and network technologies, and in particular, to a method, a module, a system, a computing device, and a storage medium for accessing a target service.
Background
Currently, when a client sends a message to a designated server point-to-point for a target service access, the message is usually forwarded by using an intermediate proxy server. For example, a target server registers with a proxy server and establishes a connection, and a client (e.g., a browser) installed on a client device (e.g., a personal computer) receives and transmits a message through a WebSocket service after being started. WebSocket is a communication Protocol that enables full duplex communication over a single TCP (Transmission Control Protocol) connection. When the client sends the message to the WebSocket service, the WebSocket service forwards the message to the target server through the proxy server.
Because the proxy service generally needs to be provided by a proxy server cluster, the client establishes a point-to-point connection with any proxy server in the proxy server cluster, and the target server also establishes a point-to-point connection with any proxy server in the proxy server cluster. If the proxy server that establishes a connection with the client and the proxy server that establishes a connection with the target server are not the same, then the message may not be forwarded.
A common solution is through a distributed coordination service such as ZooKeeper (a centralized service that maintains configuration information, names, provides distributed synchronization, and provides group services). The target server and the proxy server are both registered in the ZooKeeper, the client inquires the proxy server information which is registered in the ZooKeeper and connected with the target server before sending the message to the target server, and the client establishes connection with the target server to send the message. ZooKeeper is a centralized service to which all services need to establish connections.
In other words, when a client connects to a different target server, a new connection needs to be created with the proxy server connected to the target server, i.e., the client must create connections with multiple proxy servers, and the influence of excessive connection times on the system performance cannot be ignored.
Therefore, a new target service access method is needed to optimize the above process.

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.
FIG. 1 shows a schematic diagram of a target service access system 100 according to one embodiment of the invention. It should be noted that the target service access system 100 of fig. 1 is only exemplary, and in a specific implementation, there may be different numbers of client devices, proxy servers, and target servers in the target service access system 100 according to actual situations, and the present invention is not limited thereto.
As shown in fig. 1, the target service access system 100 includes a target server 111, a target server 112, a proxy server 121, a proxy server 122, a client device 131, and a client device 132. The proxy server 121 establishes communication connections with the target server 111 and the client device 131, respectively, and the proxy server 122 establishes communication connections with the target server 112 and the client device 132, respectively. The proxy server 121 and the proxy server 122 may form a proxy server cluster, which is communicatively connected to each other, and on which a target service access module (not shown in fig. 1) is deployed, and on each of the client device 131 and the client device 132, a client (not shown in fig. 1) that needs to access a target service is installed.
A brief example of a target service access procedure is given below. The client installed on the client device 131 transmits a target service access request to the proxy server 121, and the target service access module in the proxy server 121 receives the target service access request, determines the target server 112 corresponding to the target service access request as a server to be accessed, and takes the proxy server 122 connected to the target server 112 as a target proxy server.
Since the proxy server 122 is not the proxy server 121 that received the target service access request, the target service access module in the proxy server 121 transmits the target service access request to the proxy server 122. Proxy server 122 receives the target service access request and forwards the target service access request to target server 112. Target server 112 receives the target service access request and then responds to it, and returns the target service access result to proxy server 122.
The proxy server 122 receives the target service access result and then transmits the target service access result to the proxy server 121. The target service access module in the proxy server 121 receives the target service access result and feeds it back to the client installed on the client device 131.
It should be noted that although the client devices 131 and 132 shown in fig. 1 are illustrations of computing devices, the device types are not limited thereto, and the client devices 131 and 132 may be computing devices (such as personal computers, etc.) or mobile terminals (such as smartphones, etc.), and the present invention is not limited thereto.
FIG. 2 shows a schematic diagram of a target service access system 200 according to yet another embodiment of the invention. It should be noted that the target service access system 200 of fig. 2 is only exemplary, and in a specific implementation, there may be different numbers of client devices, proxy servers, and target servers in the target service access system 200 according to actual situations, and the present invention is not limited thereto.
For convenience of understanding, the construction of the proxy server will be briefly described below.
For each proxy server, after the proxy server is started, a proxy server is created based on a Netty (a high-performance event-driven, asynchronous and non-blocking network input/output framework) technology, and a WebSocket service is created. When a certain proxy server is selected to establish a connection with a certain target server, the proxy server can be regarded as a server of the Netty service, a corresponding proxy server can be established for the target server, and the target server can be regarded as a client of the Netty service.
When the WebSocket service receives a request (such as a page request in a browser) from a client device, if the proxy server is a target server corresponding to the request for the first proxy access, a proxy client is created, and a connection is established with a proxy server in a proxy server connected to the target server.
Therefore, after the system starts to operate normally, each proxy server at least consists of three parts, namely a WebSocket service part, a proxy client and a proxy server. The WebSocket service is used for interacting with a page in a client (such as a browser) installed on client equipment, the proxy server is used for interacting with a connected target server, the proxy client is used for forwarding a page request received by the WebSocket service to the corresponding proxy server, receiving a result processed by the proxy server and returning the result to the WebSocket service, and the WebSocket service returns the result to the client for page display.
As shown in fig. 2, the target service access system 200 includes a client device 1, a proxy server 210, a proxy server 220, and a target server 2. For convenience of description, the target server 1 establishing a connection with the proxy server 210 and the client device 2 establishing a connection with the proxy server 220 are omitted in fig. 2.
The proxy server 210 may provide WebSocket service (denoted as WebSocket1), and is deployed with a proxy client 1 and a proxy server 1, and the proxy server 220 may also provide WebSocket service (denoted as WebSocket2), and is deployed with a proxy client 2 and a proxy server 2.
The client device 1 is installed with a client, which is a browser, and when a user accesses a browser page, the browser creates a connection with the WebSocket1 in the proxy server 210 and creates a Session (Session). WebSocket1 stores sessions in the form of key-value pairs in a local cache.
After the browser page establishes a connection with WebSocket1, a list of currently available target servers is queried according to an interface provided by proxy server 210. The user can select a target server, a query instruction, etc. that the user needs to query, for example, if a machine CPU (Central Processing Unit) of the query target server 2 queries, the user requests a proxy service through a WebSocket protocol, and if a request URL (Uniform Resource locator) is "ws:// 192.168.73.1: 10079/linux/CPU" for querying, the WebSocket1 receives a browser page and sends selected target service information. That is, the proxy server 210 receives the target service access request issued by the client device 1.
From the target service access request, it may be determined that the target server 2 is a server to be accessed, and the proxy server 220 connected to the target server 2 is a target proxy server. Since the proxy server 210 is not the proxy server 220 and receives the target service access request, the proxy client 1 in the proxy server 210 needs to send the target service access request to the proxy server 2 in the proxy server 220.
The proxy server 2 forwards the target service access request to the target server 2, and the target server 2 responds to the received target service access request and returns a target service access result to the proxy server 2. After receiving the target service access result, the proxy server 2 sends the target service access result to the proxy client 1, and the proxy client 1 feeds the received target service access result back to the client device 1 through the WebSocket1 so as to display the target service access result in the browser page.
FIG. 3 shows a block diagram of a computing device 300, according to one embodiment of the invention.
As shown in FIG. 3, in a basic configuration 302, a computing device 300 typically includes a system memory 306 and one or more processors 304. A memory bus 308 may be used for communication between the processor 304 and the system memory 306.

The example processor core 314 may include an Arithmetic Logic Unit (ALU), a Floating Point Unit (FPU), a digital signal processing core (DSP core), or any combination thereof. The example memory controller 318 may be used with the processor 304, or in some implementations the memory controller 318 may be an internal part of the processor 304.
Depending on the desired configuration, system memory 306 may be any type of memory including, but not limited to: volatile memory (such as RAM), non-volatile memory (such as ROM, flash memory, etc.), or any combination thereof. System memory 306 may include an operating system 320, one or more applications 322, and program data 324.

An example communication device 346 can include a network controller 360, which can be arranged to facilitate communications with one or more other computing devices 362 over a network communication link via one or more communication ports 364.
A network communication link may be one example of a communication medium. Communication media may typically be embodied by computer readable instructions, data structures, program modules, and may include any information delivery media, such as carrier waves or other transport mechanisms, in a modulated data signal. A "modulated data signal" may be a signal that has one or more of its data set or its changes made in a manner that encodes information in the signal. By way of non-limiting example, communication media may include wired media such as a wired network or private-wired network, and various wireless media such as acoustic, Radio Frequency (RF), microwave, Infrared (IR), or other wireless media. The term computer readable media as used herein may include both storage media and communication media.
Computing device 300 may be implemented as a personal computer including both desktop and notebook computer configurations. Of course, computing device 300 may also be implemented as part of a small-form factor portable (or mobile) electronic device such as a cellular telephone, a digital camera, a Personal Digital Assistant (PDA), a personal media player device, a wireless web-watch device, a personal headset, an application specific device, or a hybrid device that include any of the above functions. And may even be implemented as a server, such as a file server, a database server, an application server, a WEB server, and so forth. The embodiments of the present invention do not limit this.
In an embodiment according to the invention, the computing device 300 may be implemented as a proxy server 121, 122 as shown in FIG. 1, or a proxy server 210, 220 as shown in FIG. 2, and configured to perform the target service access method 400 according to the invention. Among other things, application 322 disposed on an operating system contains therein a plurality of program instructions for carrying out the target service access method 400 of the present invention, which may instruct processor 304 to carry out the target service access method 400 of the present invention such that computing device 300 accesses a target service by carrying out the target service access method 400 of the present invention.
According to one embodiment of the present invention, application 322 disposed on an operating system includes a target service access module 500, the target service access module 500 containing a plurality of program instructions for performing target service access method 400 of the present invention, such that target service access method 400 of the present invention may be performed in target service access module 500.
FIG. 4 shows a flow diagram of a target service access method 400 according to one embodiment of the invention. Target service access method 400 may be performed in a target service access module 500 of a computing device (e.g., computing device 300 described above). The target service access method 400 is described below with reference to the target service access system 200 as an example.
As shown in fig. 4, the method 400 begins at step S410. In step S410, a target service access request sent by any one of a plurality of client devices is received.
According to an embodiment of the present invention, before step S410, the method 400 further includes starting a proxy service to create a proxy server and a WebSocket service, and saving start information of the proxy server to the cache server, where the start information includes an IP (Internet Protocol) address, a port, and a start time.
Of course, before the proxy service is started, a nginnx server (a high-performance network and a reverse proxy server) needs to be deployed for load balancing. The target service access system 100 shown in fig. 1 and the target service access system 200 shown in fig. 2 may also include a Nginx server and the above-described cache server.
Then, a plurality of proxy servers are deployed. Taking fig. 2 as an example, a proxy server 210 and a proxy server 220 may be deployed. Modifying the Nginx service configuration information, configuring a server routing address in an HTTP (Hyper Text Transfer Protocol) module, setting the server routing address as an IP address and a port of a plurality of deployed proxy servers (such as the proxy server 210 and the proxy server 220) and using the IP address and the port for load balancing of requests. When a request is made to access the Nginx server, the Nginx server forwards the request to one proxy server according to the routing rule.
After the proxy service is started, a proxy server is established based on the Netty technology, and a WebSocket service is established. For example, proxy server 1 and WebSocket1 are created for proxy server 210, and proxy server 2 and WebSocket2 are created for proxy server 220. Then, the proxy Server 1 and the proxy Server 2 are started, and the IP addresses, ports, and start time of the two proxy servers are saved to a cache Server implemented by a Remote Dictionary service (Redis).
In addition, proxy 210 and proxy 220 provide an interface for querying the list of currently available proxy servers, through which proxy queries may be made from cache servers.
And deploying and starting a plurality of corresponding target servers according to the service, and creating a client of the Netty service by using a Netty technology. When the target server is started, the proxy server is inquired through a currently available proxy server list provided by the proxy server, and one proxy server needing to be connected can be selected according to different algorithms such as a random algorithm or a polling algorithm.
Taking the target server 2 in fig. 2 as an example, if the proxy server 220 is selected by a random algorithm, the target server 2 is a client of the Netty service, and the proxy server 2 in the proxy server 220 is a server of the Netty service.
According to an embodiment of the present invention, before step S410, the method further includes receiving a proxy connection request from any target server of the plurality of target servers, establishing a connection with the target server that sent the proxy connection request in response to the proxy connection request, and storing connection information in the cache server.
In this embodiment, after receiving the proxy connection request from the target server 2, the proxy server 2 in the proxy server 220 will respond to the proxy connection request to establish a connection with the target server 2. The target server 2 establishes a long TCP connection from point to point with it through the IP address and port provided by the proxy server 2.
The proxy server 2 stores the connection information with the target server 2 in a cache server, and a list of connection information between all target servers and the proxy server is maintained in the cache server.
The following is an example of a format of the connection information:
in order to ensure the stable connection between the target server and the proxy server, the target server sends heartbeat information to a proxy server in the proxy server connected with the target server at regular intervals (such as 30 seconds), and the proxy server sends corresponding reply information to the target server after receiving the heartbeat information sent by the target server. If the target server does not receive the reply information of the proxy server continuously for a plurality of times (for example, 3 times), the target server determines that the proxy server cannot provide the service, and the target server initiates the creation of a new connection again to select the proxy server from the available proxy servers.
In addition, if the target server is offline, the proxy server connected with the target server is disconnected, and the proxy server deletes the connection information of the target server and the proxy server in the cache server. In fig. 2, operations related to the connection process between the proxy server 210 and the target server 1, which are not shown, can be referred to the connection process between the proxy server 220 and the target server 2, and are not described herein again.
Before receiving the target service access request, the related contents of establishing a WebSocket service connection, creating a session, providing an interface so as to query a currently available target server list, requesting a query, and the like are already described in the foregoing description on the target service access system 200, and are not described in detail in the following.
According to an embodiment of the present invention, after the proxy server 210 receives the target service access request sent by the client device 1, the process proceeds to step S420, where a target server corresponding to the target service access request is determined as a server to be accessed, and a proxy server connected to the server to be accessed is determined as a target proxy server.
In this embodiment, according to the target service access request, the corresponding target server 2 is determined as the server to be accessed, and the proxy server 220 to which the target server 2 is connected is determined as the target proxy server.
According to an embodiment of the present invention, before performing step S430, the method 400 further includes: if the proxy server receiving the target service access request is used for proxy access of the server to be accessed for the first time, a proxy client is established for the proxy server receiving the target service access request through the WebSocket service, and connection is established between the proxy client and a proxy server in the target proxy server; and storing the established connection relation in a local cache in a key value pair mode, and starting a proxy client in the proxy server which receives the target service access request.
Since the proxy server 210 that receives the target service access request firstly proxies the proxy server 220, that is, firstly queries whether a corresponding connection relationship exists from the local cache, the proxy server creates a proxy client 1 through the WebSocket1, and establishes a connection with the proxy server 2 in the proxy server 220. And storing the established connection relation in a local cache in a key value pair mode, and starting the proxy client 1. If there is a target server 2 connected to the proxy server 220 through the proxy server 210, the connection relationship may be directly obtained from the local cache.
And if the proxy server receiving the target service access request does not perform proxy access on the server to be accessed for the first time, acquiring a corresponding connection relation from the local cache, and establishing connection between the proxy client in the proxy server receiving the target service access request and the proxy server in the target proxy server according to the connection relation.
In step S430, if the target proxy server is not the proxy server that received the target service access request, the target service access request is sent to the target proxy server to instruct the target proxy server to forward the target service access request to the server to be accessed, and receive the target service access result returned by the server to be accessed.
According to one embodiment of the invention, the target service access request can be sent to the target proxy server in the following way to instruct the target proxy server to forward the target service access request to the server to be accessed. In the embodiment, the target service access request is sent to the proxy server in the target proxy server through the proxy client in the proxy server which receives the target service access request to indicate the proxy server in the target proxy server, and the target service access request is forwarded to the server to be accessed.
The target proxy server is the proxy server 220, and not the proxy server 210 which receives the target service access request, the target service access request is sent to the proxy server 2 in the proxy server 220 through the proxy client 1 in the proxy server 210, so as to instruct the proxy server 2 to forward the target service access request to the target server 2.
According to another embodiment of the invention, if the target proxy server is the proxy server which receives the target service access request, the target service access request is forwarded to the server to be accessed so as to receive the target service access result returned by the server to be accessed. In this embodiment, if the target proxy server is a proxy server that receives the target service access request, the target service access request is sent to a proxy server in the target proxy server through a proxy client in the target proxy server to indicate the proxy server in the target proxy server, the target service access request is forwarded to the server to be accessed, and a target service access result returned by the server to be accessed is received.
Finally, step S440 is executed to receive the target service access result sent by the target proxy server, and feed back the target service access result to the client device sending the target service access request.
According to an embodiment of the present invention, after receiving a target service access request sent by the proxy server 2, the target server 2 responds to the target service access request and sends a corresponding target service access result to the proxy server 2. The proxy server 2 sends the received target service access result to the proxy client 1 in the proxy server 210. The proxy client 1 receives the target service access result, and feeds back the target service access result to the client device 1 through the WebSocket 1.
According to an embodiment of the invention, the method 400 further comprises: sending heartbeat information to the target proxy server according to a preset time interval to indicate the target proxy server to feed back reply information; and if the reply information is not received for the preset times, determining that the target proxy server cannot provide the proxy service, and providing an available proxy server for the server to be accessed again.
In this embodiment, heartbeat information is sent to the proxy server in the target proxy server through the proxy client in the proxy server receiving the target service access request, typically at a predetermined time interval, so as to instruct the proxy server in the target proxy server to feed back the reply information.
For example, the time interval is set to 30 seconds, the preset number of times is 3, the proxy client 1 sends heartbeat information to the proxy server 2 every 30 seconds, and the proxy server 2 feeds back reply information to the proxy client 1 after receiving the heartbeat information. If the proxy client 1 does not receive the reply information for 3 consecutive times, it is determined that the proxy server 220 or the proxy server 2 cannot provide the proxy service, and an available proxy server is newly provided for the target server 2.
FIG. 5 shows a schematic diagram of a target service access module 500 according to one embodiment of the invention. The target service access module 500 resides in a proxy server, such as the proxy servers 121, 122 shown in fig. 1, or the proxy servers 210, 220 shown in fig. 2, and the computing device 300 shown in fig. 3 may be implemented as a proxy server. The target service access module 500 accesses the target server by performing the target service access method 400 of the present invention.

Subsequently, the determination unit 520 may determine a target server corresponding to the target service access request as a server to be accessed, and a proxy server connected to the server to be accessed as a target proxy server. The sending unit 530 may send the target service access request to the target proxy server to instruct the target proxy server to forward the target service access request to the server to be accessed and receive a target service access result returned by the server to be accessed, when the target proxy server is not the proxy server that received the target service access request. The feedback unit 540 may receive the target service access result sent by the target proxy server and feed back the target service access result to the client device that sent the target service access request.
It should be noted that the receiving unit 510 is configured to execute the aforementioned step S410, the determining unit 520 is configured to execute the aforementioned step S420, the sending unit 530 is configured to execute the aforementioned step S430, and the feedback unit 540 is configured to execute the aforementioned step S440. Here, for the execution logic of the receiving unit 510, the determining unit 520, the sending unit 530 and the feedback unit 540, reference may be made to the detailed description of steps S410 to S440 in the method 400, and details are not repeated here.
According to the target service access scheme provided by the embodiment of the invention, after a target service access request sent by client equipment is received, a target server corresponding to the target service access request is determined to be used as a server to be accessed, a proxy server connected with the server to be accessed is used as a target proxy server, the target service access request is sent to the target proxy server so as to instruct the target proxy server to forward the target service access request to the server to be accessed, a target service access result returned by the server to be accessed is received, the target service access result sent by the target proxy server is received, and the target service access result is fed back to the client equipment sending the target service access request, so that the decentralized client and the multi-service endpoint point-to-point communication are realized.
In the technical scheme, the configuration is simplified through decentralization, the project complexity caused by introducing the distributed coordination service is avoided, and the client equipment is ensured to be connected with one proxy server to access all target services. The intermediate routing rules are forwarded by the proxy service internally, and each client device does not need to establish connection with each proxy server, so that the connection times are reduced, the access safety is ensured, and the risk of exposing the information of the target server to the outside is avoided.
