jung-kurt/gofpdf pdf 生成操作
基于jung-kurt/gofpdf 生成pdf 文件
参考demo
- main.go
package main
import (
"fmt"
"log"
"github.com/gobuffalo/packr/v2"
"github.com/jung-kurt/gofpdf"
"github.com/shirou/gopsutil/v3/mem"
)
func main() {
box := packr.New("pdf", "./font")
pdf := gofpdf.New("P", "mm", "A4", "")
arialBytes, err := box.Find("arial.ttf")
if err != nil {
log.Fatal(err)
}
arialItalicBytes, err := box.Find("arial_italic.ttf")
if err != nil {
log.Fatal(err)
}
arialBoldBytes, err := box.Find("arial_bold.ttf")
if err != nil {
log.Fatal(err)
}
notoSansBytes, err := box.Find("NotoSansSC-Regular.ttf")
if err != nil {
log.Fatal(err)
}
pdf.AddUTF8FontFromBytes("ArialTrue", "", arialBytes)
pdf.AddUTF8FontFromBytes("ArialTrue", "I", arialItalicBytes)
pdf.AddUTF8FontFromBytes("ArialTrue", "B", arialBoldBytes)
pdf.AddUTF8FontFromBytes("NotoSansSC-Regular", "", notoSansBytes)
pdf.SetFont("NotoSansSC-Regular", "", 16)
pdf.AddPage()
v, _ := mem.VirtualMemory()
htmlStr := fmt.Sprintf("内存信息: Total: %v, Free:%v, UsedPercent:%f%%\n", v.Total, v.Free, v.UsedPercent)
_, lineHt := pdf.GetFontSize()
html := pdf.HTMLBasicNew()
html.Write(lineHt, htmlStr)
err = pdf.OutputFileAndClose("mem-report.pdf")
if err != nil {
log.Fatalln("some wrong: ", err.Error())
}
}
- 代码说明
通过packr进行字体文件的嵌入,同时集成了gopsutil 过去系统内存,然后输出pdf文件 - 效果
说明
网上的一些说法gopdf不支持中文是不对的,是支持的,但是比较推荐使用signintech/gopdf,毕竟还在维护,支持的特性也不错
