basic methods.Specifically, the usage skills are based on different generators, because after all these third parties do not have a unified specification, they are all habits.I have compiled a program myself, but how can I implement it with a compiler? Write the compiler by yourself.

Technology selectionIn order to solve the problem that the QR code cannot be scanned, the appropriate technical means must be chosen. Since our app refers to someone else's developed zbar-based image recognition plug-in, without the ability to modify the image recognition plug-in, I decided to solve this problem on the server side, considering the general type of the algorithm, in the service-side verificat

, due to the large amount of business card information, a QR code generation error occurs. we have marked it in red at the beginning of this article. the get method can only transmit 2 K big data at most, we need to use the POST request when the data is larger than 2 K. Therefore, in actual use, we can first obtain the QR cod
