GoLand IDE创建go项目

这里项目名称为 toPDF

package main

import (

"fmt"

"github.com/adrg/go-wkhtmltopdf"

"log"

)

func main(){

pdf.Init()

defer pdf.Destroy()

// Create object from url

object1, err := pdf.NewObject("https://www.baidu.com/")

if err != nil {

log.Fatal(err)

}

object1.SetOption("footer.right", "[page]")

// Create converter

converter := pdf.NewConverter()

defer converter.Destroy()

// Add created objects to the converter

converter.AddObject(object1)

// Add converter options

converter.SetOption("documentTitle", "Sample document")

converter.SetOption("margin.left", "10mm")

converter.SetOption("margin.right", "10mm")

converter.SetOption("margin.top", "10mm")

converter.SetOption("margin.bottom", "10mm")

// Convert the objects and get the output PDF document

output, err := converter.Convert()

if err != nil {

log.Fatal(err)

}

fmt.Println(string(output))

}

下载下来之后，运行go run main.go

报：找不到gcc编译器

下载安装MinGW

下载安装mingw-w64-install.exe

添加到path环境变量：C:\javaware\mingw\mingw64\bin

下载wkhtmltopdf

go-wkhtmltopdf项目又依赖于wkhtmltopdf，

terminal中输入: go get github.com/wkhtmltopdf/wkhtmltopdf进行下载

再次执行：go run main.go

结果报错：fatal error: wkhtmltox/pdf.h: No such file or directory

报错原因，看了一下，应该是如下的include引起的：

package pdf

/*

#cgo LDFLAGS: -lwkhtmltox

#include

#include

#include

*/

import "C"

import (

"errors"

"unsafe"

)

type Converter struct {

converter *C.wkhtmltopdf_converter

settings *C.wkhtmltopdf_global_settings

objects []*Object

}

...

wkhtmltox

又牵扯到了wkhtmltox，继续下载github.com/tcort/wkhtmltox

尝试go get github.com/tcort/wkhtmltox

结果报：go: warning: “github.com/tcort/wkhtmltox/…” matched no packages

手动下载binary：https://wkhtmltopdf.org/downloads.html

这里我下载了wkhtmltox-0.12.5-1.mxe-cross-win64.7z，里面包含：

./bin

libwkhtmltox.a

wkhtmltox.dll

wkhtmltoimage.exe

wkhtmltopdf.exe

./include/wkhtmltox

dllbegin.inc

dllend.inc

image.h

pdf.h

然后

把include里面的wkhtmltox目录复制到MinGW64的安装目录：

C:\javaware\mingw\mingw64\x86_64-w64-mingw32\include

把bin里面的 libwkhtmltox.a， wkhtmltox.dll拷贝到：

C:\javaware\mingw\mingw64\x86_64-w64-mingw32\lib

把bin里面的wkhtmltoimage.exe，wkhtmltopdf.exe拷贝到：

C:\javaware\mingw\mingw64\x86_64-w64-mingw32\bin

再次执行：go run main.go

这次终于运行成功了：

/CreationDate (D:20181025170310+08'00')
