Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.
Fig. 1 is a flow chart of a communication method of teaching live broadcast according to an embodiment of the present application. As shown in fig. 1, the method includes the following steps S101, S102, and S103.
Step S101: acquiring operation information of each message transmitting end, generating a first message packet of the operation information according to a preset protocol data format, and transmitting the first message packet to a server end;
step S102: the method comprises the steps that a server side carries out priority evaluation on a received first message packet and then sends the first message packet to a corresponding message receiving side, or carries out priority evaluation on a second message packet after generating the second message packet based on operation information in the first message packet and then sends the second message packet to the corresponding message receiving side;
step S103: the message receiving end extracts the operation information in the first message packet or the second message packet and responds to the operation information;
wherein the priority evaluation comprises: message quality evaluation, judging the grammar complexity and the content repeatability of a first message packet or a second message packet to be sent so as to preferentially send the first message packet or the second message packet with high grammar complexity and low content repeatability; the client evaluates, judges the role level of each message sending end and each message receiving end, and preferentially transmits the first message packet of the message sending end with high role level or the second message packet generated by the response of the priority transmission server end, and preferentially transmits the second message packet to the message receiving end with high role level.
In this embodiment, the priority evaluation includes: message quality evaluation, judging the grammar complexity and the content repetition degree of a first message packet or a second message packet to be transmitted so as to preferentially transmit the grammar complexity high and the content repetition degree low; for example, MESSAGEs (chat MESSAGEs) such as "teacher good", "11", "111" and "1" have low syntax complexity and high repetition of MESSAGE content, and have low meaning to many MESSAGE receiving ends, so that the server end may preferentially send a MESSAGE with relatively high quality, resend a MESSAGE with low quality, and even discard sending for some MESSAGEs with high repetition and low syntax complexity.
The client evaluates, judges the role level of the message sending end and the message receiving end, and preferentially transmits the first message packet of the message sending end with high role level or the second message packet after the response of the first message packet, and preferentially transmits the first message packet to the message receiving end with high role level. Illustratively, the role level shares the levels of an administrator, a master teacher, a teaching aid, a student and the like in a high-low order, and the server side can preferentially send messages to the administrator, the master teacher and the teaching aid and can preferentially send messages to the administrator, the master teacher and the teaching aid.
It should be noted that the role level can be set not only according to the identity, etc., but also according to the actual requirements (such as according to the interaction time and the speaking quality).
It should be noted that, priority order of different message packets may be set through the fields of the message packets, and when the message packets are sent, field priority evaluation is performed on the message packets, which is that the message packets are sent according to the preset field priority order. In this embodiment, the priority transmission order of some message packets is as follows: the MESSAGE type field is MESSAGE and the MESSAGE type field is MESSAGE, the MESSAGE type field is IQ and the MESSAGE type field is set, the MESSAGE type field is IQ and the MESSAGE type field is get, the MESSAGE type field is PRESENCE, the MESSAGE type field is MESSAGE and the MESSAGE type field is groupchat.
It should be noted that, the message sent by the client does not need to have a sender identifier field, and the server can obtain from the session.
Wherein the protocol data is JSON format.
The MESSAGE type field comprises four values of get (query), set (setting), result (result) and error (error) when the MESSAGE type field is IQ (request MESSAGE); when the MESSAGE type field is MESSAGE, the MESSAGE type field type includes: three values of groupchat (group chat), error and notification; when the message type field is a client status message, the message type field includes: the values of unavailable, available and error are three values.
For example, when a teacher wants to change setting information (such as a live-broadcast room name, a live-broadcast room state, whether to allow speaking) of a live-broadcast room, a client side (client side) where the teacher is located sends a first message packet according to instruction information of the teacher, where the content of the first message packet is shown in fig. 3, a value of a message category field category is IQ, a value of a message identification field id is unique-id, a value of a receiving end identification field to is/rotor/abcd, that is, a number of abcd live-broadcast rooms, a value of a message type field type is set, that is, a set-class message, a body extension field includes a request field and a parameters field, a request value is/rotor/update, which indicates that information update of the live-broadcast room is performed, a value of a name of the live-broadcast room, a value of a status field has OPEN and a CLOSED optional, which indicates that a status of the live-broadcast room is set, and a volume is used for live-broadcast instruction and a live-broadcast interaction field, and a volume interaction field is set in a live-broadcast extension field, and a live-broadcast interaction field is included in the live-broadcast instruction field.
When only a certain field is set, only the setting field and its value are set in the body, for example, only the forbidden operation is performed, only the allowcat field and its value false are set in the body field, and no unchanged field such as the name field is set.
After receiving the content of the first MESSAGE packet, the server side generates a second MESSAGE packet, where the content of the second MESSAGE packet is shown in fig. 4, the value of the MESSAGE category field is MESSAGE, the value of the MESSAGE identification field id is uniq-id, the value of the sender identification field from is/ROOM/abcd, that is, the number is abcd direct broadcast ROOM, the value of the MESSAGE type field type is notification, the content in the body field is correspondingly modified according to the content of the first MESSAGE packet, the value of the type field in the body field is chat_room_update, which indicates that the live broadcast information is UPDATED, and other fields (name field, status field, allowcat and allowrequst voice) and the value information thereof are put into the detail field in the body field, that is, specific UPDATED content.
The server side sends a second message packet to the student client side, and the student client side extracts the content in the body field in the second message packet to indicate that specific change information of the live broadcasting room is received.
It should be noted that, when the teacher issues the interactive questions, the client of the teacher sends the related information of the interactive questions to the server through the Http protocol, and the server generates a third message packet according to the protocol data format and sends the third message packet to the student client, that is, notifies the student client that there are new interactive questions, where the content of the third message packet is shown in fig. 5, and the value of the onGoingInteraction has two types of interaction id and null, and the interaction id is the name of the interactive question.
After the student client receives the third message packet, the student client responds to the interactive questions through an http protocol. The server generates a fourth message packet based on the answer content and sends the fourth message packet to each client, wherein the content of the fourth message packet is shown in fig. 6, and the fourth message packet comprises an interactive title name field, an answer session ID field, an answer field response field.
For another example, when the student wants to request for wheat connection, the student client generates a corresponding fifth message packet and sends the fifth message packet to the server, the content of the fifth message packet is shown in fig. 7, the server forwards the fifth message packet to the teacher client, the teacher responds to the request of the fifth message packet at the teacher client, generates a sixth message packet for starting wheat connection based on the response of the teacher and sends the sixth message packet to the server, the content of the sixth message packet is shown in fig. 8, the server responds to the executing wheat connection instruction of the sixth message packet, and generates a seventh message packet indicating that wheat connection is successful to each client; the seventh message packet content is shown in fig. 9, when any client end wants to cancel the wheat connection, the client end generates a corresponding eighth message packet and sends the eighth message packet to the server end, and the server end responds to the eighth message packet to execute the wheat connection cancellation instruction as shown in fig. 10.
The protocol data further includes an acknowledgement field ackRequired, and the value of the acknowledgement field ackRequired includes true and false, and it should be noted that the acknowledgement field ackRequired is added only when the content of the message packet is important. Illustratively, for the first message packet that needs to acknowledge the retransmission field and has been successfully sent, if no ACK message packet reply returned by the server is received within 10s, then the client needs to resend, and the message id remains unchanged. The maximum number of retries is 3. It should be noted that, the ACK MESSAGE packet includes an id, a MESSAGE type field and a MESSAGE type field of the first MESSAGE packet, where the value of the MESSAGE type field category includes two types of MESSAGE and IQ, and the MESSAGE type field type includes two types of result and error, and result represents acknowledgement receipt.
It should be noted that, the transmission principle of other corresponding message packets such as a hand-lifting request and information sending about the client in the live interaction is as above, and will not be described herein.
The protocol method further comprises a heartbeat mechanism, wherein the heartbeat mechanism adopts a ping mode, and a flow chart of the heartbeat mechanism is shown in fig. 11.
