The invention automatically detects the change of the network information in real time through the local area network server, and immediately transmits the changed network information to the external network server for storage once the change of the network information is detected; when the APP of the mobile terminal needs to communicate with the LAN server, the APP of the mobile terminal initiates a LAN connection request to the LAN server, and the LAN server acquires network information corresponding to the LAN server according to the LAN connection request and establishes communication connection, so that communication between the APP of the mobile terminal and the LAN server is realized. By the technical scheme of the invention, the local area network server can still adopt the dynamic IP address, so that the data security of the local area network can be ensured; meanwhile, the communication interaction between the APP of the mobile terminal and the local area network server can be realized through the transfer of the external network server, and great convenience can be brought to actual use. The technical scheme of the invention is applied to the campus local area network, so that the communication between the APP of the mobile terminal and the local area network server of the campus is facilitated on the basis of ensuring the data security of the campus local area network, i.e. the interaction between the internal network and the external network is realized, and the sharing of resources in the campus is facilitated.
In the embodiment of the invention, the client program is installed on the local area network server, the network information of the local area network server is detected in real time through the client program, and when the change of the network information of the local area network server is detected, the client program actively transmits the changed network information to the external network server. The client program running on the local area network server is responsible for detecting the network information, and the changed network information is actively transmitted to the external network server in time after the change of the network information is detected, so that the external network server can update the network information in the local area network information management node in time, and the APP access of the mobile terminal is not influenced; meanwhile, the client program runs on the local area network server independently, is only used for monitoring the change of the network information and actively uploading the changed network information, and cannot affect other programs of the local area network server.
In the embodiment of the invention, the external network server is provided with the server program, receives the changed network information through the server program, and updates the changed network information to the local area network information management node through the server program. The server program running on the external network server is specially responsible for receiving the network information uploaded by the client program and updating the network information in the local area network information management node in time so as to ensure that the APP access of the mobile terminal is not influenced; meanwhile, the server program is also independently operated on the extranet server, and other programs of the extranet server cannot be influenced.
The invention is specially responsible for the transmission and management of network information by utilizing a client program installed on a local area network server and a server program installed on an external network server, and has strong real-time performance and reliability; and in the concrete implementation, only need with client program install local area network server and with the server program install the outer net server can, the realization process is simple, convenient.
In the embodiment of the invention, when the local area network server is powered on and started, the client program automatically runs, reports the online information to the server program and keeps communication with the server program in real time; and meanwhile, the client program acquires initial network information of the local area network server when the local area network server is started and transmits the initial network information to the server program of the external network server. By automatically operating the client program when the local area network server is powered on and started, the external network server can timely acquire the network information of the local area network server after the local area network server is on line.
In the embodiment of the invention, when a server program of an external network server receives initial network information, whether a matched local area network information management node exists in the external network server is searched based on the initial network information, and if the matched local area network information management node exists, the initial network information is updated to the matched local area network information management node; and if the matched local area network information management node does not exist, the external network server creates a new local area network information management node and stores the initial network information into the newly created local area network information management node. When the local area network server is temporarily offline and then online due to faults and the like, the external network server is allocated with the local area network information management nodes, so that initial network information can be directly updated to the matched local area network information management nodes without creating new local area network information management nodes; if the local area network server is newly accessed, the corresponding local area network information management node does not exist in the external network server, so that a new local area network information management node needs to be created.
In the embodiment of the invention, when the external network server creates a new local area network information management node, the newly created local area network information management node is bound with the corresponding client program, so that the server program can update the network information to the corresponding local area network information management node according to the binding relationship when receiving the network information transmitted by the client program.
In the embodiment of the invention, when the client program acquires the initial network information, the initial network information is recorded so as to facilitate the subsequent comparison detection; in the running process of the local area network server, the client program acquires the network information of the local area network server in real time, compares the acquired network information with the recorded network information, judges that the network information of the local area network server is not changed if the network information is consistent, and continuously acquires the network information of the local area network server and compares the network information with the recorded network information; if the network information is inconsistent, the network information of the local area network server is judged to be changed, the client program transmits the changed network information to the server program of the external network server, changes the recorded network information into the changed network information, and meanwhile continuously acquires the network information of the local area network server and compares the network information with the recorded network information. For example, the initial network information obtained by the client program is 192.168.1.1, and the client program records the network information 192.168.1.1; after a period of time, if the client program detects that the network information of the lan server becomes 192.168.2.221, the client program will change the original record 192.168.1.1 to 192.168.2.221 in addition to transmitting the changed 192.168.2.221 to the server program of the extranet server.
In the embodiment of the present invention, a client management list is created in an extranet server, all local area network servers accessed to the extranet server are added to the client management list, and the client management list is managed by a server program, which specifically includes: when the server program receives the online information reported by the client program, setting a corresponding local area network server in the client management list to be in an online state; and when the server program detects that the client program is disconnected from communication, setting the corresponding local area network server in the client management list to be in an offline state. The client management list is set in the external network server to manage each accessed local area network server, so that the external network server can conveniently master the online condition of each local area network server in real time.
In the embodiment of the invention, when the APP of the mobile terminal initiates a local area network connection request to an external network server, whether the corresponding local area network server in a client management list is in an online state is searched based on the local area network connection request, and if the corresponding local area network server is in the online state, network information is continuously acquired from a local area network information management node; and if the mobile terminal is not in the on-line state, directly feeding back a connection failure result to the APP of the mobile terminal. The processing efficiency of the request can be improved by searching whether the local area network server to be accessed is on line or not when the local area network connection request is received, and directly feeding back a connection failure result to the APP of the mobile terminal if the local area network server is not on line.
In the embodiment of the invention, after the connection result is fed back to the APP of the mobile terminal by the extranet server, whether the APP of the mobile terminal initiates an interaction request is detected, if the APP of the mobile terminal continuously exceeds the preset time and does not initiate the interaction request, the extranet server disconnects the established communication connection, so as to avoid the waste of extranet server resources; otherwise, the established communication connection is kept so as to facilitate the interaction between the APP of the mobile terminal and the local area network server. In specific implementation, for example, after the extranet server establishes a communication connection with the local area network server according to the acquired network information, if the APP of the mobile terminal does not initiate any interaction request within 5 consecutive minutes, the extranet server disconnects the established communication connection; if the APP of the mobile terminal has an initiating interaction request within 5 continuous minutes, the established communication connection is maintained.
In the embodiment of the present invention, the network information at least includes an IP address. Of course, in the implementation, other network information may also be included, for example, information related to a server name, a reporting time, and the like may be included.
In an embodiment of the present invention, the interconnection method further includes: the local area network server is provided with a management platform, after an administrator logs in the management platform, the access authentication information is uploaded to the external network server through the management platform, and the external network server stores the received access authentication information into the local area network information management node;
