Claims (4)

1. A method of local and cloud network communication, comprising the steps of:
step 1, a proxy server and a cloud springboard machine establish and maintain connection of an upward proxy tunnel and a downward proxy tunnel;
specifically, when the proxy server is started, three ports of the proxy server and three ports of the cloud board hopping machine are opened; the three ports of the proxy server are respectively: a first server side uplink proxy port (S1), a server side downlink monitoring port (S2) and a second server side uplink proxy port (S3); the three ports of the cloud board jumping machine are respectively: an uplink monitoring port (C1) of the springboard machine, a downlink proxy port (C2) of the springboard machine and a downlink monitoring port (C3) of the springboard machine;
binding a first service end uplink proxy port (S1) and a plate hopping machine uplink monitoring port (C1), thereby establishing an upward proxy tunnel; binding a service end downlink monitoring port (S2) and a springboard machine downlink proxy port (C2), thereby establishing a downward proxy tunnel;
step 2, binding each original application program developed locally with a unique corresponding byte code enhancement plug-in; any original application is represented as: the original application program Pro, the byte code enhancement plug-in bound with the original application program Pro is expressed as: byte code enhancement plugins AE (Pro);
each time the original application Pro starts, the following two actions are performed:
behavior 1: the original application program Pro sends a registration request of a local original application program to a registration center; wherein, the registration request contains the communication address of the original application program Pro;
the byte code enhancement plugin AE (Pro) intercepts the registration request and sends the registration request to the registration center, and the registration center records the communication address of the original application program Pro;
behavior 2: an upward proxy local tunnel is established between the byte code enhancement plugin AE (Pro) and a second server-side uplink proxy port (S3) of the proxy server;
step 3, the communication process of the original application program Pro sending the message to the cloud network:
step 3.1, in the whole life cycle of the original application program Pro, when the original application program Pro sends a network request message, the network request message is intercepted by the byte code enhancement plugin AE (Pro);
step 3.2, the byte code enhancement plugin AE (Pro) judges the type of the intercepted network request message, if the intercepted network request message is a request message for local resources, the intercepted network request message is directly forwarded to a local destination address; if the network request message is a network request message for cloud network resources, the byte code enhancement plugin AE (Pro) sends the network request message to the proxy server through an established upward proxy local tunnel;
step 3.3, the proxy server sends the network request message to the cloud board hopping machine through the established upward proxy tunnel;
step 3.4, the cloud board jumper sends the network request message to a cloud network, so that a communication process that an original application program Pro sends the message to the cloud network is realized;
step 4, the cloud network accesses the communication process of the original application program Pro:
step 4.1, when the cloud network needs to access the original application program Pro, the cloud network searches the registry to obtain the communication address of the original application program Pro to be accessed;
step 4.2, a temporary cloud transmission tunnel is established between the cloud network and a down monitoring port (C3) of the springboard machine of the cloud springboard machine, and an access request for an original application program Pro is sent to the cloud springboard machine through the temporary cloud transmission tunnel;
step 4.3, the cloud springboard machine forwards an access request to the original application program Pro to the proxy server through the established downward proxy tunnel;
and 4.4, when the proxy server receives the access request to the original application program Pro, establishing a temporary local transmission tunnel from the proxy server to the original application program Pro according to the communication address of the original application program Pro, sending the access request to the original application program Pro through the temporary local transmission tunnel, closing the temporary local transmission tunnel by the proxy server, and simultaneously notifying a cloud springboard machine to close the temporary cloud transmission tunnel to realize the communication process of accessing the original application program Pro by the cloud network.
2. The method of claim 1, wherein the cloud network comprises a micro-service, a database, a message queue, and a cache.
3. The method of claim 2, wherein the micro services are configured with micro service bytecode enhancement plug-ins;
when the micro service initiates a request, the request is intercepted by the micro service byte code enhancement plugin, the micro service byte code enhancement plugin judges the type of the request, and if the request is a request for other devices in the cloud network, the request is directly forwarded to the target device; and if the request is a request for the local application, forwarding the request to the cloud board hopping machine.
4. A method of local and cloud network communication as claimed in claim 1, wherein when the original application Pro needs to be exited, the following two actions are performed before the exit:
behavior 1: the original application program Pro sends a request for deleting registration information to a registration center; the byte code enhancement plugin AE (Pro) intercepts the request for deleting the registration information and sends the request for deleting the registration information to the registry so that the registry deletes the registration information of the original application program Pro;
behavior 2: the proxy server closes the upward proxy local tunnel between the bytecode enhanced plugin AE (Pro) and the proxy server.
