Gin middleware/handler to enable Cache.
Download and install it:
go get github.com/gin-contrib/cacheImport it in your code:
import "github.com/gin-contrib/cache"See the example
package main
import (
"fmt"
"time"
"github.com/gin-contrib/cache"
"github.com/gin-contrib/cache/persistence"
"github.com/gin-gonic/gin"
)
func main() {
r := gin.Default()
store := persistence.NewInMemoryStore(time.Second)
r.GET("/ping", func(c *gin.Context) {
c.String(200, "pong "+fmt.Sprint(time.Now().Unix()))
})
// Cached Page
r.GET("/cache_ping", cache.CachePage(store, time.Minute, func(c *gin.Context) {
c.String(200, "pong "+fmt.Sprint(time.Now().Unix()))
}))
// Listen and Server in 0.0.0.0:8080
r.Run(":8080")
}You can also use the Delete and Flush methods with the InMemory store:
// Delete a specific cache entry by key
err := store.Delete("your-cache-key")
if err != nil {
// handle error
}
// Flush all cache entries
err = store.Flush()
if err != nil {
// handle error
}Here is

a complete example using Redis as the cache backend with NewRedisCacheWithURL:
package main
import (
"fmt"
"time"
"github.com/gin-contrib/cache"
"github.com/gin-contrib/cache/persistence"
"github.com/gin-gonic/gin"
)
func main() {
r := gin.Default()
// Basic usage:
store := persistence.NewRedisCacheWithURL("redis://localhost:6379", time.Minute)
// Advanced configuration with password and DB number:
// store := persistence.NewRedisCacheWithURL("redis://:password@localhost:6379/0", time.Minute)
r.GET("/ping", func(c *gin.Context) {
c.String(200, "pong "+fmt.Sprint(time.Now().Unix()))
})
// Cached Page
r.GET("/cache_ping", cache.CachePage(store, time.Minute, func(c *gin.Context) {
c.String(200, "pong "+fmt.Sprint(time.Now().Unix()))
}))
// Listen and serve on 0.0.0.0:8080
r.Run(":8080")
}
