Two-dimensional code encoding method, two-dimensional code decoding method, and electronic device

A method, comprising:

• obtaining, by an electronic device, a to-be-decoded two-dimensional code, wherein the to-be-decoded two-dimensional code indicates first information;
• obtaining, by the electronic device, mode indication information from the to-be-decoded two-dimensional code;
• determining, by the electronic device, a coding mode for the to-be-decoded two-dimensional code from the mode indication information, wherein the electronic device stores one or more mapping relationship tables, and the mapping relationship table comprises the mode indication information and a coding mode corresponding to the mode indication information;
• and
• decoding, by the electronic device based on the coding mode, the to-be-decoded two-dimensional code to obtain the first information.

An electronic device, comprising:

• a communication interface;
• a non-transitory memory;
• and
• a processor, wherein the communication interface and the non-transitory memory are coupled to the processor, the non-transitory memory is configured to store computer program code, the computer program code comprises computer instructions, and when the processor reads the computer instructions from the non-transitory memory, the electronic device is enabled to:
• obtain, by the electronic device, to-be-encoded text, wherein the to-be-encoded text comprises N characters, and N is a positive integer;
• determine, by the electronic device from X optional coding modes, a target coding mode for each of the N characters;
• group, by the electronic device, the N characters into M character fields based on the target coding mode for each of the N characters, and determining a target coding mode for each of the M character fields, wherein M is less than or equal to N;
• encode, by the electronic device, the M character fields based on the target coding mode for each of the M character fields to obtain a first binary character string;
• and
• generate, by the electronic device based on the first binary character string, a two-dimensional code of a version corresponding to a length of the first binary character string.
