[0003] In the prior art, the IP address and port number of the server may be the public network address and port number mapped by Network Address Translation (NAT), and the public network address and port number after NAT mapping are dynamically changed. The client cannot obtain the public network address and port number of the server after real-time changes, resulting in the client being unable to access the server normally

Embodiment Construction
[0043] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.
[0044] The method for accessing the server provided by the embodiment of the present invention can be applied to figure 1 network shown. Such as figure 1 As shown, the network may specifically be a blockchain network, and the blockchain network includes multiple bookkeeping nodes, and each bookkeeping node can record the domain name, IP address and port number issued by the server. ...

Embodiments of the present invention provide a method, a device, and a computer-readable storage medium for accessing a server. In this embodiment of the present invention, the accounting node of the blockchain receives the domain name registration information sent by the server and signed by the server with a private key, where the domain name registration information includes the domain name, IP address, port number, and client corresponding to the server. The download address of the client program, so that the blockchain node that needs to access the server can obtain the domain name registration information of the server from the accounting node, and download the client program according to the download address of the client program in the domain name registration information. Program to make the client program access the server through the IP address and port number in the domain name registration information, when the IP address and port number of the server change dynamically, ensure that the client can normally obtain the server after the real-time change The public network address and port number to ensure that the client can access the server normally.
Description
technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a method, device, and computer-readable storage medium for accessing a server. Background technique [0002] Usually, when a client accesses a server, it needs to resolve the domain name of the server into the IP address of the server, so that the client accesses the server through the IP address of the server. When the client accesses the server, it usually accesses based on the default port number. [0003] In the prior art, the IP address and port number of the server may be the public network address and port number mapped by Network Address Translation (NAT), and the public network address and port number after NAT mapping are dynamically changed. The client cannot obtain the public network address and port number of the server after real-time changes, resulting in the client being unable to access the server normally. Contents of t...
