Context Propagation Go
This middleware is used for support propagate context between micro services.
For this version, we propagate context by opentracing baggage protocol.
Supported framework for auto inject and extract:
How to use
Operate data from context
Before get or set data from context, you should enable auto inject and extract.
go get -u github.com/AminoApps/context-propagation-gopackage main
import cp "github.com/AminoApps/context-propagation-go"
ctx = cp.SetValueToContext(ctx, "my-key", "my-value")
valye := cp.GetValueFromContext(context.Background(), "my-key")Auto inject and extract
Gin
go get -u github.com/AminoApps/context-propagation-go/module/context-propagation-ginpackage main
import cpgin "github.com/AminoApps/context-propagation-go/module/context-propagation-gin"
e := gin.New()
e.Use(cpgin.Middleware())
// For propagation context from gin, please use the context from the request
func TestApi(c *gin.Context) {
GetDataFromDataBase(c.Request.Context())

// Please use the ctxhttp to wrap the request.
