example (Instance)BI,IP。IPBC Construction , 1 BC example BI
[0056] When it is necessary to generate an instance (Instance) BI of the block type BC for storing traceability information of agricultural products, execute the block initialization process IP. IP is the constructor of BC, first generate a BC instance BI;
[0057] BI=new BC();
[0058] IP assigns values to each attribute of BH and BB in BI respectively, and sets them as default values:
[0059] BI.BH.BS=0;
[0060] BI.BH.PH=””;
[0061] BI.BH.NC=””;
[0062] BI.BH.HH=””;
[0063] BI.BB.BD=””;
[0064] BI.BB.DH=””;
[0065] After the initialization process IP is completed, the block assignment process AP is started.
[0066] Assuming that the input traceability information of agricultural products is plain text, after serializing it in JSON (JavaScript Object Notation) format, the obtained values are as follows:
[0067] {
[0068] "SPU": "1230056781234",
[0069] "SKU": "c1e26952-514e-4a69-bcfd-776774fbe04c",
[0070] "PN": "Early Spring Red Jade",
