Functions ¶
func Dump ¶
func Dump(values ...interface{})
Dump dumps a variable to stdout with more manually readable.
func DumpTo ¶
func DumpTo(writer io.Writer, value interface{}, option gutil.DumpOption)
DumpTo writes variables `values` as a string in to `writer` with more manually readable
func DumpWithOption ¶
func DumpWithOption(value interface{}, option gutil.DumpOption)
DumpWithOption returns variables `values` as a string with more manually readable.
func DumpWithType ¶
func DumpWithType(values ...interface{})
DumpWithType acts like Dump, but with type information. Also see Dump.
func I18n ¶
I18n returns an instance of gi18n.Manager. The parameter `name` is the name for the instance.
func IsEmpty ¶
func IsEmpty(value interface{}) bool
IsEmpty checks whether given `value` empty. It returns true if `value` is in: 0, nil, false, "", len(slice/map/chan) == 0. Or else it returns true.
func IsNil ¶
IsNil checks whether given `value` is nil. Parameter `traceSource` is used for tracing to the source variable if given `value` is type of pinter that also points to a pointer. It returns nil if the source is nil when `traceSource` is true. Note that it might use reflect feature which affects performance a little.
func Listen ¶
func Listen()
Listen is an alias of gproc.Listen, which handles the signals received and automatically calls registered signal handler functions. It blocks until shutdown signals received and all registered shutdown handlers done.
func Log ¶
Log returns an instance of glog.Logger. The parameter `name` is the name for the instance.
func RequestFromCtx ¶
RequestFromCtx retrieves and returns the Request object from context.
func Resource ¶
Resource returns an instance of Resource. The parameter `name` is the name for the instance.
func Server ¶
Server returns an instance of http server with specified name.
Example ¶
package main
import (
"github.com/wowqhb/gf/v2/frame/g"
"github.com/wowqhb/gf/v2/net/ghttp"
)
func main() {
// A hello world example.
s := g.Server()
s.BindHandler("/", func(r *ghttp.Request) {
r.Response.Write("hello world")
})
s.SetPort(8999)
s.Run()
}
Output:
func SetDebug ¶
func SetDebug(enabled bool)
SetDebug enables/disables the GoFrame internal logging manually. Note that this function is not concurrent safe, be aware of the DATA RACE, which means you should call this function in your boot but not the runtime.
func Throw ¶
func Throw(exception interface{})
Throw throws an exception, which can be caught by TryCatch function.
func Try ¶
Try implements try... logistics using internal panic...recover. It returns error if any exception occurs, or else it returns nil.
func TryCatch ¶
func TryCatch(ctx context.Context, try func(ctx context.Context), catch ...func(ctx context.Context, exception error))
TryCatch implements try...catch... logistics using internal panic...recover. It automatically calls function `catch` if any exception occurs ans passes the exception as an error.
func Validator ¶
Validator is a convenience function, which creates and returns a new validation manager object.
