The data transmission method of the embodiment of the application can be executed by a data transmission device, for example, and the data transmission device can be disposed in a first electronic device such as a smart phone, a tablet computer, and a smart watch.
As shown in fig. 1, the data transmission method of this embodiment may include the following steps 1100 to 1400:
at step 1100, serialized data definition structure information is determined from the object data.
In this embodiment, since the object data and the serialized data definition structure based on the serialized communication belong to different types of information representations, and both can be converted into byte stream data for transparent transmission based on the communication protocol, the object data part and the serialized data definition structure part are separated, the serialized data definition structure part is removed from the storage of the application program, and is acquired from the cloud server when necessary, so that the storage space of the application program can be saved.
Specifically, in a case that serialized communication is required, the first electronic device may determine serialized data definition structure information according to object data of the serialized communication, in this embodiment, the serialized data definition structure information may be acquired from a cloud server, and after acquiring the serialized data definition structure information, the first electronic device may further verify the serialized data definition structure information to obtain a verification result; and determining that the operating environment is in a normal operating state according to the verification result.
