GoLand IDE创建go项目 这里项目名称为 toPDF
添加main.go文件，添加main函数, 例子来自： https://github.com/adrg/go-wkhtmltopdf
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)) } GoLand terminal 执行 go run main.go GoLand会自动提示下载github.com/adrg/go-wkhtmltopdf 也可以手动在terminal中输入: go get github.com/adrg/go-wkhtmltopdf来下载下载下来之后，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 <stdio.h> #include <stdlib.h> #include <wkhtmltox/pdf.h> */ 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：
