# OFDGo [](https://pkg.go.dev/github.com/xiaoqidun/ofdgo)
|
|
首个原生、全平台兼容的纯 Go 语言 OFD 渲染库
|
|
|
|
|
|
# 在线体验
|
|
[OFDGo WebUI](https://ofdgo.aite.me/)，将OFDGo编译为WASM提供服务
|
|
|
|
# 一键部署
|
|
```shell
|
|
docker run -d -p 80:80 ccr.ccs.tencentyun.com/xiaoqidun/ofdgo:latest
|
|
```
|
|
|
|
# 构建指南
|
|
```batch
|
|
:: 1. 编译OFDGo WASM
|
|
set GOOS=js
|
|
set GOARCH=wasm
|
|
go build -o assets/webui/ofdgo.wasm -trimpath -ldflags "-s -w -buildid=" ./cmd/webui/wasm.go
|
|
:: 2. 编译OFDGo WebUI
|
|
set GOOS=windows
|
|
set GOARCH=amd64
|
|
go build -o ofdgo_webui.exe -trimpath -ldflags "-s -w -buildid=" ./cmd/webui/webui.go
|
|
```
|
|
|
|
# 安装为库
|
|
```shell
|
|
go get -u github.com/xiaoqidun/ofdgo
|
|
```
|
|
|
|
# 快速调用
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"log"
|
|
"os"
|
|
|
|
"github.com/xiaoqidun/ofdgo"
|
|
)
|
|
|
|
func main() {
|
|
// 1. 打开OFD文件
|
|
reader, err := ofdgo.Open("test.ofd")
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
defer reader.Close()
|
|
// 2. 创建PDF文件
|
|
pdfFile, err := os.Create("test.pdf")
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
defer pdfFile.Close()
|
|
// 3. 渲染PDF文件
|
|

# 签名验证
