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 Go ¶
func Go( ctx context.Context, goroutineFunc func(ctx context.Context), recoverFunc func(ctx context.Context, exception error), )
Go creates a new asynchronous goroutine function with specified recover function.
The parameter `recoverFunc` is called when any panic during executing of `goroutineFunc`. If `recoverFunc` is given nil, it ignores the panic from `goroutineFunc` and no panic will throw to parent goroutine.
But, note that, if `recoverFunc` also throws panic, such panic will be thrown to parent goroutine.
func I18n ¶
I18n returns an instance of gi18n.Manager. The parameter `name` is the name for the instance.
func IsEmpty ¶
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.
The parameter `traceSource` is used for tracing to the source variable if given `value` is type of pointer that also points to a pointer. It returns true if the source is empty when `traceSource` is true. Note that it might use reflect feature which affects performance a little.
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 pointer 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/gogf/gf/v2/frame/g"
"github.com/gogf/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 and passes the exception as an error.
But, note that, if function `catch` also throws panic, the current goroutine will panic.
func Validator ¶
Validator is a convenience function, which creates and returns a new validation manager object.
