ServerConfig is the HTTP Server configuration manager.

func ConfigFromMap 

func ConfigFromMap(m map[string]interface{}) (ServerConfig, error)

ConfigFromMap creates and returns a ServerConfig object with given map and default configuration object.

func NewConfig 

func NewConfig() ServerConfig

NewConfig creates and returns a ServerConfig object with default configurations. Note that, do not define this default configuration to local package variable, as there are some pointer attributes that may be shared in different servers.

type ServerStatus 

type ServerStatus = int

ServerStatus is the server status enum type.

type Session 

type Session = gsession.Session

Session is actually an alias of gsession.Session, which is bound to a single request.

type UploadFile 

type UploadFile struct {
	*multipart.FileHeader `json:"-"`
	// contains filtered or unexported fields
}

UploadFile wraps the multipart uploading file with more and convenient features.

func (UploadFile) MarshalJSON 

func (f UploadFile) MarshalJSON() ([]byte, error)

MarshalJSON implements the interface MarshalJSON for json.Marshal.

func (*UploadFile) Save 

func (f *UploadFile) Save(dirPath string, randomlyRename ...bool) (filename string, err error)

Save saves the single uploading file to directory path and returns the saved file name.

The parameter `dirPath` should be a directory path, or it returns error.

Note that it will OVERWRITE the target file if there's already a same name file exist.

Example

Custom saving file name. 

package main

import (
	"gitee.com/clannad_sk/webkit/v2/frame/g"
	"gitee.com/clannad_sk/webkit/v2/net/ghttp"
	"gitee.com/clannad_sk/webkit/v2/os/gfile"
)

func main() {
	s := g.Server()
	s.BindHandler("/upload", func(r *ghttp.Request) {
		file := r.GetUploadFile("TestFile")
		if file == nil {
			r.Response.Write("empty file")
			return
		}
		file.Filename = "MyCustomFileName.txt"
		fileName, err := file.Save(gfile.Temp())
		if err != nil {
			r.Response.Write(err)
			return
		}
		r.Response.Write(fileName)
	})
	s.SetPort(8999)
	s.Run()
}

Output:

type UploadFiles 

type UploadFiles []*UploadFile

UploadFiles is an array type of *UploadFile.

func (UploadFiles) Save 

func (fs UploadFiles) Save(dirPath string, randomlyRename ...bool) (filenames []string, err error)

Save saves all uploading files to specified directory path and returns the saved file names.

The parameter `dirPath` should be a directory path or it returns error.

The parameter `randomlyRename` specifies whether randomly renames all the file names.

type WebSocket deprecated 

type WebSocket struct {
	*websocket.Conn
}

WebSocket wraps the underlying websocket connection and provides convenient functions.

Deprecated: will be removed in the future, please use third-party websocket library instead.
