S404, sending a request to the stopped service by taking the preset time interval as a reference and multiplying the time interval until the time interval for sending the request reaches the termination time interval.
In the embodiment of the present invention, after determining that the service is stopped, it is further necessary to continue to send a request to the stopped service to further determine the state of the service. Specifically, the method and the device use a preset time interval as a reference and send a request to the stopped service in a time interval multiplication mode, if return information aiming at the service is received in the preset time, the service is determined to be alive, the current time interval for sending the request is recovered to the preset time interval, and the state of the service is continuously monitored; and if the return information aiming at the service is not received within the preset time, continuing to send the request to the stopped service in a time interval multiplication mode until the time interval for sending the request reaches the termination time interval.
It should be noted that the default state of the service in the blockchain is alive, and if the snooping is not successful, that is, the sent service sending request does not respond more than 3 times, the state of the service can be marked as down. When the monitoring thread in the service monitoring module is not closed, the heartbeat signal is sent in a time interval multiplication mode so as to determine whether the service is connected or not until the time interval is 1 hour. It should be noted that the number of responses and the time interval may be configured according to actual situations, and the embodiment of the present invention is not specifically limited herein.

S406, when the information returned by the service for the request is received again, determining that the service is alive.
In an embodiment provided by the invention, before the service of the server is offline, an offline interface of the server needs to be called, then a preset intelligent contract deployed on a node is executed, relevant information of the corresponding service in the server, such as an IP address, a weight and the like, is deleted from a time state database, and the deleted information of the service can be automatically synchronized to other nodes of a bottom chain through a data synchronization mechanism of the bottom chain, so that distributed fault tolerance of registration discovery is realized; the preset intelligent contract of the bottom layer chain deletes the address of the server from the event state, a service deletion notice is sent to the service monitoring module, and the service monitoring module closes the corresponding monitoring thread, so that the operation of closing the corresponding service in the block chain is realized.
As shown in fig. 3, in an embodiment provided by the present invention, the method further includes:
s201, receiving a service acquisition request sent by a client.
Wherein, the service acquisition request comprises the identifier of the request service. Specifically, the client executes the preset intelligent contract of the node by calling a discover interface of the server.
S202, obtaining the server IP address corresponding to the identification of the request service according to a preset strategy.
And inquiring the time status database by executing a preset intelligent contract, and acquiring an alive service address list according to the status information of the storage service of the monitoring module, wherein if one node is down, the server can adaptively inquire other nodes so as to provide the IP address of the server.

The service registration information also includes server weights. In the embodiment of the present invention, the preset policy includes at least one of server weight randomization, server weight round-robin, server minimum delay, and server minimum load balancing algorithm.
S203, the server IP address is sent to the client, so that the client can obtain and cache the service in the server according to the server IP address.
Note that, when a new service or an original service state in the server is changed, the new service or the original service state is notified to the client through an event. The client decides whether to reacquire the server IP address more than itself. The bottom layer chain also supports certificate verification, when the client side obtains the service list, the issued certificate is sent, the server firstly verifies the legality of the client side, and therefore the security of the framework is better.
In one embodiment provided by the present invention, the method further comprises: when a new service or the original service state is changed, notifying the client through an event; and the client determines whether to acquire the new service or the service with the changed state according to the event.
