Description
Technical Field
The present application relates to the field of computer control technologies, and in particular, to a method, a system, a device, and a storage medium for online collaboration based on a browser.
Background
With the popularity of networks and the increase in bandwidth, more and more companies choose to collaborate remotely for communication, working, etc. In the related art, according to the content of manipulation, the remote collaboration system can be divided into two types, one is a remote control type system for manipulating the desktop of the whole system, and the other is an online collaboration type system for transmitting an in-application interface or data.
For the remote control system, it is common to use remote desktop software built in the Windows system or some third party software (such as Teamviewer). The architecture of the system is generally divided into a client and a server, wherein the server is one, the client can be multiple, and the server shares the desktop content of the whole system. The cooperation mode is as follows: a client controls a server by sending an instruction to the server, so that the desktop of the server displays specific content; the server side sends the desktop content to all clients participating in the cooperation; and after receiving the desktop content transmitted by the server, the client draws the corresponding content on a client interface.
For online collaboration systems, various types of online document editing software are common. The architecture of the system is similar to that of a remote control system, and the system also comprises a client and a server. The server shares the server application data. The cooperation mode is as follows: a client sends an instruction to a server; after receiving the instruction, the server performs corresponding processing to generate output data and sends the output data to each client connected with the server; and after receiving the application data transmitted by the server, the client draws corresponding content on a client interface.
However, both of the above remote collaboration systems have disadvantages. For a remote control system, a client controls the whole system where a server is located, and the whole system has all the rights of a server user, so that the server system is always in a safety risk caused by possible illegal operation of the client, and serious artificial potential safety hazards are caused; in addition, remote control systems are generally only used in a trusted environment, and the scope of the use scenario is limited. For an online collaboration system, a client can only control a single application of a server, and although the problem of security does not occur, the content contained in the server is limited.
At present, no effective solution is provided for the problem that the security and the content cannot be compatible in the related technology.

Fig. 1 is a flowchart (one) of an online collaboration method according to an embodiment of the present application. As shown in fig. 1, an online collaboration method includes:
step S102, acquiring a control instruction transmitted by a first client under the condition of establishing connection with the first client;
step S104, forwarding the control instruction to a server;
s106, obtaining rendering content which is transmitted by a server and corresponds to the control instruction;
step S108, transmitting the rendering content to the first client;
wherein, the server is a browser.
In the present embodiment, the control terminal performs the above steps as an execution main body.
Wherein there is one and only one first client.
The first client is a client having at least an authorization function, that is, the first client can control whether other clients access online collaboration, and control any one of the other clients to perform input operation.
In some embodiments, the first client further has a play-out function, that is, the first client has a function of sending an operation instruction to the control end.
In some embodiments, the server may run solely in the cloud; or the server and the first client run in the same system, and at the moment, the first client is the client of the online collaboration initiator; or the service end and the control end operate in the same system.
In an embodiment of the present invention, under the condition that the server runs in the cloud alone, at this time, the first client and the server do not establish a communication connection, and the first client cannot acquire the content of the server, and thus cannot display and control the server.
In an embodiment of this embodiment, when the server and the first client operate in the same system, at this time, although the first client establishes a communication connection with the server, the server and the control end, and the first client and the control end are respectively established; if the control end does not transmit the rendered content of the server to the first client, that is, the online collaboration relationship is not established, the first client may display and control the server, but the operation is limited to local operation and is not cloud operation.
In an embodiment of this embodiment, the server and the control end operate in the same system, and the implementation manner of the server and the manner of the server operating in the cloud separately are the same, which is not described herein again.
In this embodiment, a control end is added between a first client and a server, the first client and the server are isolated, and the first client controls the server through the control end, that is, the first client only controls a browser through the control end, but does not control a system where the server is located, so that the security of online collaboration is improved; in addition, because the content that the browser can present is more than that of a single software or a single document, the content richness and convenience of online collaboration are improved, and the online collaboration efficiency is improved.
Fig. 2 is a flowchart of an online collaboration method according to an embodiment of the present application (ii). As shown in fig. 2, the online collaboration method further includes:
step S202, under the condition of establishing connection with a second client, acquiring an operation instruction transmitted by the second client;
step S204, forwarding the operation instruction to a server;
step S206, obtaining rendering content which is transmitted by the server and corresponds to the operation instruction;
and step S208, transmitting the rendering content to the first client and the second client.
In the present embodiment, the control terminal performs the above steps as an execution main body.
Wherein there is one and only one second client.
The second client is a client with a broadcasting function, that is, the second client has a function of sending an operation instruction to the control end.
In this embodiment, in the presence of the second client, the first client only has the authorization function, that is, the first client cannot send an operation instruction to the control end and can only display the rendered content of the server.
Specifically, under the condition that a first client and a second client exist simultaneously, the first client and the second client perform online collaboration, the first client and the second client both display rendering content of a server, at this time, the second client controls the server through a control end, that is, the second client operates the server, and content of the operation of the second client on the server is displayed in real time on the first client and the second client.
In this embodiment, a control end is added between the second client and the server, the second client is isolated from the server, and the second client controls the server through the control end, that is, the second client only controls the browser through the control end, but does not control the system where the server is located, so that the security of online collaboration is improved; in addition, because the content that the browser can present is more than that of a single software or a single document, the content richness and convenience of online collaboration are improved, and the online collaboration efficiency is improved.
Fig. 3 is a flowchart (iii) of an online collaboration method according to an embodiment of the present application. As shown in fig. 3, the online collaboration method further includes:
step S302, under the condition of establishing connection with a third client, acquiring a control instruction transmitted by a first client and/or an operation instruction transmitted by a second client;
step S304, forwarding the control instruction and/or the operation instruction to a server;
step S306, obtaining rendering content which is transmitted by the server and corresponds to the control instruction and/or the operation instruction;
and step S308, transmitting the rendering content to the first client, the second client and the third client.
In the present embodiment, the control terminal performs the above steps as an execution main body.
Wherein, the number of the third clients can be several.
The third client is a client only having a receiving function, that is, the third client can only display the rendered content of the server and cannot operate the server through the control end.
In this embodiment, the clients are divided into a first client having an authorization function, a second client having a broadcast function, and a third client having a receiving function, different clients are classified, and only one client (i.e., the second client) is allowed to operate the server under the condition of online collaboration, and the other clients (the first client and the third client) can obtain rendering content of the server transmitted by the control end in real time, so as to ensure online collaboration efficiency.
Fig. 4 is a flowchart (iv) of an online collaboration method according to an embodiment of the present application. As shown in fig. 4, the online collaboration method further includes:
step S402, acquiring an application instruction transmitted by a third client;
step S404, forwarding the application instruction to the first client;
step S406, obtaining an approval instruction which is transmitted by the first client and corresponds to the application instruction;
step S408, forwarding the approval instruction to the third client so as to convert the third client into a second client;
and under the condition that a second client exists before the third client is converted into the second client, the second client is converted into a third client.
In the present embodiment, the control terminal performs the above steps as an execution main body.
In step S402, the application instruction is an instruction for converting the third client into the second client, that is, the third client wants to have an instruction for transmitting an operation instruction (an instruction for operating the server through the control end) to the control end.
In step S406, the first client is an authorized client, which can determine whether to convert the third client into the second client. Under the condition that the first client determines that the third client can be converted into the second client, the first client generates an approval instruction; and under the condition that the first client determines that the third client cannot be converted into the second client, the first client generates a rejection instruction.
In step S408, in the case that the third client is converted into the second client, the control end will determine whether the second client exists before the conversion; if the second client exists, the control end marks the old second client as a third client, namely, only one second client exists at the same time.
In this embodiment, the third client needs to apply for the application to be converted into the second client. Therefore, under the condition of online collaboration, the first client side has the right of deciding the conversion of the rest of the client sides into the second client sides, so that only one second client side is ensured at the same time, and the situation that a plurality of client sides operate the server side at the same time is avoided.
Fig. 5 is a flowchart (v) of an online collaboration method according to an embodiment of the present application. As shown in fig. 5, the online collaboration method further includes:
step S502, acquiring first key information transmitted by a server;
step S504, second key information transmitted by the client is obtained;
step S506, judging whether the second key information corresponds to the first key information;
step S508, in the case that the second key information corresponds to the first key information, establishing a connection with the client.
In the present embodiment, the control terminal performs the above steps as an execution main body.
In step S502, when the server establishes a connection with the controller, the first key information of the server is stored in the controller. The first key information is generally a password or random code, so as to improve the security and privacy of online collaboration.
In step S504, the second key information is the key information acquired by the client, and is not stored in the control end. Wherein, the second key information is a password or random code.
In step S506, the control end compares the acquired second key information with the stored first key information, thereby determining whether the second key information is correct.
And under the condition that the second key information does not correspond to the first key information, the control end is not connected with the client, namely, the client is refused to join online cooperation.
In this embodiment, before online collaboration is performed, whether a client is added to the collaboration is determined in a key information verification manner, so that the problem of privacy disclosure is avoided.
In some of these embodiments, the online collaboration method further comprises:
under the condition that the client does not provide the second key information, the first client judges whether the client establishes connection with the control end;
and under the condition that the first client determines that the client is connected with the control end, the control end acquires a determination instruction transmitted by the first client and marks the client as a second client or a third client.
Fig. 6 is a flowchart (vi) of an online collaboration method according to an embodiment of the present application. As shown in fig. 6, the online collaboration method further includes:
step S602, acquiring a connection establishing instruction transmitted by a client;
step S604, judging whether the client is the first client for transmitting the connection establishing instruction;
step S606, under the condition that the client side establishes a connection instruction for the first transmission, the client side is marked as a first client side, and a first notification instruction is generated;
step S608, transmitting the first notification instruction to the first client.
In the present embodiment, the control terminal performs the above steps as an execution main body.
In step S606, the first notification instruction is an instruction to notify the client to convert into the first client.
In this embodiment, the first client generally refers to a client of an online collaboration initiator, that is, a first client initiating online collaboration and connected to the control end.
Under the condition that the first client side is connected with the control side, the first client side has an authorization function and a play-out function because the second client side and the third client side do not exist at the moment.
Fig. 7 is a flowchart (seventh) of an online collaboration method according to an embodiment of the present application. As shown in fig. 7, the online collaboration method further includes:
step S702, acquiring a connection establishing instruction transmitted by a client;
step S704, judging whether the client is the first client for transmitting the connection establishing instruction;
step S706, in the case that the client is a client that does not establish a connection instruction for the first transmission, marking the client as a second client or a third client.
In the present embodiment, the control terminal performs the above steps as an execution main body.
In this embodiment, the second client and the third client are clients participating in online collaboration, that is, clients that are not write-on collaboration initiators.
And under the condition that the second client side is connected with the control side, the first client side only has an authorization function, and the second client side has a broadcasting function.
And under the condition that the third client establishes connection with the control end, the third client only has a receiving function. If the second client does not exist, the first client has an authorization function and a broadcasting function.
In this embodiment, generally speaking, after the first client initiates online collaboration, the other clients establish connections with the control end and then are all converted into third clients; only if a third client needs to be converted into the second client, the steps S402 to S408 are performed.
In this embodiment, the control end can quickly classify the clients by judging the connection order of the clients.

FIG. 9 is a flowchart of a specific application implementation of the online collaboration method according to an embodiment of the present application. As shown in fig. 9, the online collaboration method includes:
step S901, a control end resident in a cloud waits for the connection between a server and a client;
step S902, starting a server, wherein the server is connected with a control end;
step S903, the control end receives the connection of the service end;
step S904, starting a first client and connecting to a control end;
step S905, the control end receives the connection of the client and informs the server that the rendering content can be sent;
step S906, the first client becomes a broadcasting client and an authorization client;
step S907, the server sends the rendering content to the control end in real time;
step S908, the control end forwards the rendering content to the client end participating in the cooperation activity in real time;
step S909, receiving and displaying the rendering content transmitted by the control end, and waiting for other clients to participate in the cooperation activity;
step S910, connecting other clients with the control end and applying for joining in cooperation activities to become receiving clients;
step S911, the control end receives the connection of other clients and sends a request for joining the cooperative activity to the authorized client;
step S912, authorizing the client to allow other clients to join in the cooperation activity through application;
step S913, receiving the rendering content transmitted by the client display control end;
step S914, show that there is no actual meaning after a period of time;
step S915, the receiving client wants to become a broadcasting client and sends an application to the control end;
step S916, the control end may forward the application to the authorized client;
step S917, authorizing the client to pass the application and sending a message allowing the receiving client to become a broadcasting end to the control end;
step S918, the control end sends the message of passing the application to the client end of the application, and cancels the broadcasting authority of the original broadcasting client end;
step S917, receiving the message that the client receives the application to pass, becoming a broadcasting client, and starting to operate the server.
In step S901, the control end is used to monitor the connection between the service end and the client. In addition, the control end requires a high network bandwidth to send the rendered content of the service end to each client participating in the collaboration activity.
In step S902, when a collaboration activity needs to be initiated, a collaboration activity initiator locally starts a server and connects the server to the control end. The server may generate a key and send it to the controller, requesting the client that applies for participation in the collaborative activity to provide the key as an identification of the entry into the activity.
In step S903, if the server provides the key, the key is saved. At this time, the client is not connected to the control end, so the server does not send the rendering content to the control end.
In step S904, the collaboration activity initiator locally starts a client and connects it to the control end.
In step S905, the control end accepts the connection of the first client, and marks it as an authorized client and a playout client. And sends the message, which becomes the authorized client and the broadcast client, to the first client. And simultaneously, the server is informed, and the rendering content can be sent to the control end.
In step S906, the first client receives the message and switches itself to the states of the authorized client and the broadcast client. And starts to send the command for controlling the browser of the server to the control end.
In step S908, the control end forwards the instruction sent by the broadcasting client to the server end in real time, and sends the rendered content sent by the server end to the first client end in real time.
In step S909, the first client (also an authorized client, a playout client) receives the page rendering content from the server browser of the control end and renders it on the client interface. While waiting for other clients to participate in the collaborative activity.
In step S910, the collaboration activity participant locally launches a client and connects to the control end, attempting to apply for becoming a receiving client. If necessary, a key (identification code) needs to be provided.
In step S911, the control end sends the application of the client of the cooperative activity participant to the authorized client. If necessary, the control end compares the key attached during application with the key provided by the service end to judge whether the application is passed.
In step S912, the authorized client checks the client application qualification of the collaboration activity participant, and determines whether the client becomes a collaboration activity participant. If the control end controls whether the application passes or not by comparing the keys in the previous step, the step can be omitted.
In step S913, after the application is passed, the control end starts to send the rendering content to the collaboration participant client (receiving client) in real time. And after the receiving client receives the content, drawing the content on a client interface.
In step S915, if the collaboration activity participant needs to share, his receiving client may initiate an application to become a broadcasting client to the control end.
In step S916, the control end forwards the request of the receiving client for becoming the broadcasting client to the authorization client, and the authorization client determines whether it becomes the broadcasting client.
In step S919, the client applying for being the broadcast client converts itself into the broadcast client after receiving the message of successful application, and starts to send a control instruction for controlling the browser to the control end.
The client participating in the cooperation can receive the information shared by the broadcasting client in real time, and can also share the information of the client to other clients by applying for the client to become the broadcasting client, so that the remote cooperation function is realized.
FIG. 10 is a block diagram of a specific application implementation of an online collaboration system according to an embodiment of the present application. As shown in fig. 10, the online collaboration system includes a server, a control end, an authorization client (a first client), a broadcast client (a second client), and a plurality of receiving clients (a third client), where the server is connected to the control end through a network, and the authorization client, the broadcast client, and the receiving clients are respectively connected to the control end through a network.
The network may be a wired network connection or a wireless network connection. In some of these embodiments, the network may include a public network (e.g., the internet), a private network (e.g., a Local Area Network (LAN), a Wide Area Network (WAN), etc.), a wireless network (e.g., an 802.11 network, a Wi-Fi network, etc.), a cellular network (e.g., a 4G network, a 5G network, etc.), a frame relay network, a Virtual Private Network (VPN), a satellite network, a router, hub, switch, server, etc., or any combination thereof. By way of example only, the network may include a cable network, a wireline network, a fiber optic network, a telecommunications network, an intranet, a Wireless Local Area Network (WLAN), a Metropolitan Area Network (MAN), a Public Switched Telephone Network (PSTN), the like, or any combination thereof. In some embodiments, the network may include one or more network access points. For example, the network may include wired and/or wireless network access points, such as base stations and/or internet switching points, through which various devices of the auto-switching language system 100 may connect to the network to exchange information and/or data.
For the present application, the browser (i.e., server) increases the ability to process instructions from the network. The browser before modification can only process instructions generated by a local mouse, a keyboard, a touch screen and the like. After the browser (server) increases the capability of processing the instructions from the network, the client can send control instructions to the server through the network, so that the browser is remotely controlled.
In addition, browsers (servers) also increase the ability to upload rendered content to the network in real-time. The browser before modification can only render the content on a browser webpage and display the content on the local computer. The modified browser (server) can upload the content to be displayed by the browser to the network, and finally send the content to the client for display on the interface of the client.
The method and the system have the advantages that the control end is additionally arranged between the server end and the client end to carry out message forwarding and control service, and the functions are as follows:
the service is used to maintain network connections with the various clients, accept input commands from the clients, and control which client's input can currently be forwarded to the service (browser).
The service is used to maintain a connection with the server, receive output from the server, and forward the output to the respective client.
The application has the advantages that:
because the server is essentially a browser, the client controls the browser instead of a desktop like a remote desktop control system; the control behavior of the client does not cause damage to the system environment where the server is located;
personnel who do not need to participate in the cooperation have good credit, and the system where the server is located is not damaged by the participators, so that the application scene is wide;
because the server is a browser, the browser can browse rich internet contents, the browser can also use other various online collaboration tools adapted to the browser, and the content presented by the server is high in richness.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
