In at least one embodiment of the present invention, because the first IP address may not be successfully resolved due to the influence of a network environment, in order to avoid that the hardware device cannot connect to the target server due to failure of resolving the first IP address, when the first IP address fails to resolve, the obtaining unit 113 randomly obtains a second IP address from a preset operator IP address, and replaces the first IP address with the second IP address.
In at least one embodiment of the invention, the method further comprises:
the configuration unit 117 configures the operator IP in advance.
Specifically, the configuration unit 117 may configure one IP for each operator, so that although the current operator cannot be confirmed, through trial and error, the probability of IP adaptation can be effectively improved, and thus the probability of server connection can be improved.
When the second IP address is available, the obtaining unit 113 randomly obtains a target protocol from preset protocols.
In at least one embodiment of the present invention, the preset Protocol may include an HTTP Protocol (Hyper Text Transfer Protocol) and an HTTPs Protocol (Hyper Text Transfer Protocol over Secure Socket).
In at least one embodiment of the invention, the second IP address is not necessarily available due to the influence of the network environment.
Thus, the method further comprises:
when the second IP address is not available, the prohibiting unit 116 prohibits the second IP address from being acquired in the next connection operation.
By the implementation mode, the situation that unavailable IP addresses are repeatedly acquired and connection progress is delayed can be effectively avoided.
The requesting unit 114 requests the authentication server to allocate a third IP address of the target server using the target protocol based on the second IP address.
In at least one embodiment of the invention, the third IP address is used to connect to the target server.
When the third IP address is acquired, the acquiring unit 113 randomly acquires a target port from a preset port list.
In at least one embodiment of the present invention, the port list stores ports that are proven to be connected to higher power.
Specifically, the configuring unit 117 configures the port list including:
the configuration unit 117 obtains all used ports and determines the success rate of connection operations of all the ports, and the configuration unit 117 obtains the ports of which the success rate is greater than or equal to a preset threshold, and configures the port list according to the obtained ports.
For example, in order to better connect to the target server, the configuration unit 117 may configure the higher preset threshold, and the preset threshold may be configured to be 95%.
In at least one embodiment of the invention, the third IP address is likely to be unavailable due to the network environment.
Thus, the method further comprises:
when the third IP address is not acquired, the prohibiting unit 116 prohibits the target protocol from being acquired in the next connection operation.
Through the implementation mode, the invalid target protocol can be effectively prevented from being repeatedly used, and the connection efficiency is further improved.
The control unit 115 controls the hardware device to connect to the target server through the target port and the third IP address.
In at least one embodiment of the present invention, the target server is a public network server, and the hardware device is controlled to connect to the target server, so that the hardware device and the target server are in a connection controlled state, and thus when a user opens a corresponding application program of the mobile terminal, the mobile terminal can access other remote hardware devices through the target server, so that the mobile terminal of the user can connect to the hardware device anytime and anywhere.
In at least one embodiment of the invention, the hardware device is likely to fail to connect with the target server due to the influence of the network environment.
Thus, the method further comprises:
when it is detected that the hardware device is not successfully connected to the target server, the prohibiting unit 116 prohibits the target port from being acquired in the next connection operation.
By the implementation mode, the situation that the unavailable target port is repeatedly acquired and the connection progress is delayed can be effectively avoided.
In at least one embodiment of the present invention, when there is a flow operation failure in the above-mentioned flow, in order to avoid a logic error, which results in that the hardware device cannot normally connect to the target server, the method further includes:
when a preset event is detected, the execution unit 118 re-executes the server connection instruction.
In at least one embodiment of the present invention, the preset event may include, but is not limited to, one or more of the following:
(1) the second IP address is not available.
(2) The acquisition unit 113 does not acquire the third IP address.
(3) Detecting that the hardware device is not successfully connected to the target server.
(4) Detecting that the hardware device is disconnected from the target server.
(5) And detecting that the connection between the hardware equipment and the target server is abnormal.
Through the implementation mode, the server connection instruction can be re-executed when the abnormal event is detected, and the influence on the normal use of the network resources by the user and the influence on the user experience can be avoided by taking response measures in time.
In summary, the present invention can determine each hardware device to be connected when a server connection instruction is received, and perform random delay on connection operation of each hardware device, for each hardware device, when it is detected that the hardware device delay is finished, analyze a first IP address of an authentication server, when the first IP address analysis fails, randomly obtain a second IP address from a preset operator IP address, when the second IP address is available, randomly obtain a target protocol from the preset protocol, further based on the second IP address, use the target protocol to request the authentication server to allocate a third IP address of a target server, when the third IP address is obtained, randomly obtain a target port from a preset port list, and control the hardware device to connect to the target server through the target port and the third IP address, and then solve the connection problem of hardware equipment and server under the complicated network environment, has improved the success rate that hardware equipment and server are connected.
