将gin.Context转换为context.Context

Question

Is there a way to transform gin.Context to context.Context in Go? What should be used in building a Go microservice?

Answer 1

The standard library's context.Context type is an interface, with the following methods:

• Deadline() (deadline time.Time, ok bool)
• Done() <-chan struct{}
• Err() error
• Value(key interface{}) interface{}

So any type that has these methods is a context.Context.

Looking at the gin documentation, we see that the gin.Context type has all of these methods:

• Deadline
• Done
• Err
• Value

So it's already a context.Context. No conversion or transformation necessary.
