It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The technical solution provided in the embodiment of the present invention can be used in a scenario where browsers on various devices access websites quickly through clients, and an application hardware environment of the application hardware environment may be as shown in fig. 1, where fig. 1 is a schematic diagram of an application system structure of an embodiment, please refer to fig. 1, the technical solution of the present invention is applied to remote communication between a client 101 and a server 102, and the client 101 may include devices such as a personal computer, a smart phone, a tablet computer, and a personal digital assistant, but is not limited thereto. The client 101 may access a public network, such as the Internet, in a wired or wireless manner, and communicate with the server 102. The server 102 may run a browser, various communication tools, a web access tool, and the like, and a user may access the server 102 through an internet network using the browser and the like. The server in the server 102 may be implemented by an independent server or a server cluster composed of a plurality of servers.
In one embodiment, as shown in fig. 2, a remote connection method is provided, which is described by taking the method as an example applied to the client in fig. 1, and includes the following steps:
s201, sending a connection request to the server, triggering the server to detect whether the cloud desktop address of the server can be connected, and receiving a connection parameter returned by the server.
The connection parameter is a return value returned to the server when the server receives the connection request. The cloud desktop address may be an IP address of the cloud desktop. When the server receives a connection request sent by the client, whether the cloud desktop of the server is reachable (connectable) or not can be detected, if the cloud desktop is reachable, the return value can include the IP address of the cloud desktop, if the cloud desktop address is not reachable, the return value can not include the IP address of the cloud desktop, and the client can know whether the cloud desktop address of the server is reachable or not by judging whether the return value includes the IP address of the desktop or not. The return value may also include a connection mode for establishing communication between the client and the server. When the cloud desktop address is reachable, the connection mode may correspond to a virtual machine connection (VMconnect); when the cloud desktop address is not reachable, the connection mode may correspond to an MSTSC (remote desktop client).
S202, when the cloud desktop address of the server side cannot be connected, the domain name of the host of the server side can be intercepted from the connection parameters, and whether the host where the server side is located can resolve the domain name of the host of the server side is detected.
In the above step, the connection parameter may include a domain name of the server host, and when there is no cloud desktop IP in the return value, the client detects whether the client host can resolve the domain name of the server host, and performs the next operation according to the detection result.
And S203, if the domain name can be analyzed, analyzing the domain name of the server host by using the host where the domain name can be analyzed, and calling a connection instruction containing the domain name of the server host to remotely connect with the cloud desktop of the server.
In the above steps, if the client host can resolve the domain name of the server host, the VMconnect connection instruction may be directly invoked for connection, and in addition, the background of the server may also directly intercept related parameters of other servers, for example: and the user name and the password logged in by the server, the domain name and the IP of the server, the uuid of the cloud desktop and the like are returned to the client, and the client can modify the necessary configuration of the system and start the VMconnect for connection. The connection instruction can be' VMconnect host domain name cloud desktop uuid/user: host username/password: host password ".
In the remote connection method, the server detects whether the cloud desktop address of the server is connectable or not when receiving the connection request of the client, and returns the connection parameters to the client. When the cloud desktop address is connectable, the returned connection parameters may include a cloud desktop IP address, and when the cloud desktop address is not connectable, the returned connection parameters may not include the cloud desktop IP address. The client can judge whether the cloud desktop address is accessible by judging whether the connection parameters include the cloud desktop IP address. When the cloud desktop address of the server side cannot be connected, the domain name of the host machine of the server side is intercepted from the connection parameters, when the domain name of the host machine of the server side can be analyzed by the client side, a connection instruction containing the domain name of the host machine of the server side is called to carry out remote connection with the cloud desktop of the server side, when the cloud desktop address of the server side has a fault and cannot be connected, the client side is enabled to carry out remote connection with the server side through other parameters of the server side.

s301, generating a key pair, and sending a connection request to a server, wherein the connection request carries a public key in the key pair, and the connection request is used for triggering the server to encrypt connection parameters through the public key to obtain a ciphertext;
in the above steps, the key is a parameter, which is a parameter input in an algorithm for converting a plaintext into a ciphertext or converting a ciphertext into a plaintext. The whole encryption and decryption processes can be completed only by using the public key and the private key in the key pair at the same time, and a pair of keys can be randomly generated by a user when the keys are generated and are respectively used as the public key and the private key of the user.
S302, receiving the ciphertext sent by the server, and analyzing the ciphertext through a private key to obtain a connection parameter. The connection parameter obtained by analyzing the ciphertext through the private key can be a plaintext parameter.
In the embodiment, the key pair generated by the client is adopted to encrypt the connection parameters transmitted by the server and the client, so that the safety of information transmission is improved.

s401, sending a connection request to a server, triggering the server to detect whether a cloud desktop address of the server is connectable, and receiving a connection parameter returned by the server;
s402, when the cloud desktop address of the server cannot be connected, intercepting the domain name of the host of the server from the connection parameters, and detecting whether the host can resolve the domain name of the host of the server;
s4031, if the domain name of the server side host can be analyzed, the host where the domain name of the server side host is located is utilized to analyze the domain name of the server side host, and a connection instruction containing the domain name of the server side host is called to remotely connect with a cloud desktop of the server side;
s4032: if the cloud desktop cannot be analyzed, adding the mapping of the client host file locally, and calling a connection instruction containing the domain name of the server host according to the mapping to remotely connect with the server cloud desktop.
In the above embodiment, when step S4032 is executed, the domain name of the server host may be intercepted, and the IP of the server host may also be intercepted. In step S4032, the command format for locally adding the client host file may be "IP server host domain name". The type of connection instruction may be to call VMconnect connection.
