When the last time that the received HTTP data was communicated to another thread through the pipeline, it did not send the data directly past, but rather sent the data in the shared memory handle to the past, to achieve efficient communication purposes. The following is an analysis of the resource processing process, what to do after receiving the message. The processing code for this message is as follows:
#001 void Resourcedispatcher::onreceiveddata (int request_id,
#002 Sharedmemoryhandle S

Suppose that the contents of EAN are numbered from left to right: N13, N12, N11, N10, N9, N8, N7, N6, N5, N4, N3, N2, N1, where the N1 is the calibration bit to be requested:
1, c1= (n2+n4+n6+n8+n10+n12) *3;
2, C2=n3+n5+n7+n9+n11+n13;
3, add C1 and C2, take its single-digit number, set to C3;
4, check bit N1=10-C3
For example, here is an example of a EAN13 barcode:
The top three 690 represent China, 690~
