Go language tutorial manual

Course Elementary 27436

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.

How to get openid after scanning the QR code image generated with PHP?

I used the PHP QR code generation class library to generate a QR code picture (not generated by the WeChat interface). I want to get the openid of a WeChat user after scanning the QR code. How can I implement this function? (I previously thought of using web page authorization to achieve this, but the prerequisite for this is that WeChat users need to pay attention to the official account. Is it possible to directly scan the QR code to jump to the target page without users paying attention, and obtain it in the process? to his openid?)
