golang 将图片生成Base64

go 语言将 网络或本地图片转换为base64 格式

1. 获取网络图片

func GetUrlImgBase64(path string) (baseImg string ,err error){//获取网络图片client := &http.Client{Timeout: time.Second * 5, //超时时间}var bodyImg io.Readerrequest, err := http.NewRequest("GET", path, bodyImg)if err != nil {err = errors.New("获取网络图片失败")return}respImg, _ := client.Do(request)defer respImg.Body.Close()imgByte, _ := ioutil.ReadAll(respImg.Body)// 判断文件类型，生成一个前缀，拼接base64后可以直接粘贴到浏览器打开，不需要可以不用下面代码//取图片类型mimeType := http.DetectContentType(imgByte)switch mimeType {case "image/jpeg":baseImg = "data:image/jpeg;base64," + base64.StdEncoding.EncodeToString(imgByte)case "image/png":baseImg =  "data:image/png;base64," + base64.StdEncoding.EncodeToString(imgByte)}return
}

2.获取本地图片

func GetUrlImgBase64(path string) (baseImg string ,err error){//获取本地文件file, err := os.Open(path)if err != nil {err = errors.New("获取本地图片失败")return}defer file.Close()imgByte, _ := ioutil.ReadAll(file)// 判断文件类型，生成一个前缀，拼接base64后可以直接粘贴到浏览器打开，不需要可以不用下面代码//取图片类型mimeType := http.DetectContentType(imgByte)switch mimeType {case "image/jpeg":baseImg = "data:image/jpeg;base64," + base64.StdEncoding.EncodeToString(imgByte)case "image/png":baseImg =  "data:image/png;base64," + base64.StdEncoding.EncodeToString(imgByte)}return
}
