go - How to write log into .log files in golang? -


i'am new use go language, still learn , need help. how can write application logs in go language ".log" files similiar php phalcon framework ?

i have searching google , go language tutorials, there no simple understanding example. have try example logs text doesn't write continously. here's example used learn logging log, , think it's completly wrong.

package main  import (     "bufio"     "fmt"     "io/ioutil"     "os"     "time" )  func check(e error) {     if e != nil {         panic(e)     } }    func main() {      := time.now()     dt := now.format("2006-01-02")      dt2 := now.format("2006-01-02 15:04:05")      // start, here's how dump string (or     // bytes) file.     d1 := []byte("hello\ngo11\n" + dt2)     err := ioutil.writefile("/users/my/documents/work/src/logs/log-"+dt+".log", d1, 0644)     check(err)      // more granular writes, open file writing.     f, err := os.create("/users/my/documents/work/src/logs/log1.log")     check(err)      // it's idiomatic defer `close`     // after opening file.     defer f.close()      // can `write` byte slices you'd expect.     d2 := []byte{115, 111, 109, 101, 10}     n2, err := f.write(d2)     check(err)     fmt.printf("wrote %d bytes\n", n2)      // `writestring` available.     n3, err := f.writestring("writes\n" + dt)     fmt.printf("wrote %d bytes\n", n3)      // issue `sync` flush writes stable storage.     f.sync()      // `bufio` provides buffered writers in addition     // buffered readers saw earlier.     w := bufio.newwriter(f)     n4, err := w.writestring("buffered\n")     fmt.printf("wrote %d bytes\n", n4)      // use `flush` ensure buffered operations have     // been applied underlying writer.     w.flush()  } 

you're trying many different things it's hard tell you're aiming specifically, if want write logs file, here example:

package main  import (         "log"         "os" )  func main() {          //create file desired read/write permissions         f, err := os.openfile("filename", os.o_wronly|os.o_create|os.o_append, 0644)         if err != nil {                 log.fatal(err)         }             //defer close when you're done it, not because think it's idiomatic!         defer f.close()          //set output of logs f         log.setoutput(f)          //test case         log.println("check make sure works")  }
