MFC 如何调用wkhtmltopdf实现html转换pdf

news2024/11/24 7:31:45

一、wkhtmltopdf下载

1、wkhtmltopdf官网：https://wkhtmltopdf.org/

2、我的资源里面下载：https://download.csdn.net/download/my_angle2016/88368461?spm=1001.2014.3001.5503

二、wkhtmltopdf安装

1、双击wkhtmltox-0.12.6-1.msvc2015-win32.exe，点击"I Agree"

2、修改安装目录，默认是安装到"C:\Program Files (x86)\wkhtmltopdf"，这里我修改成"D:\Tools\wkhtmltopdf"，点击"Install"即可

三、MFC 调用wkhtmltopdf实现html文件转pdf文件

void ConvertHtmlToPdf(const CString& htmlFilePath, const CString& pdfFilePath) {
    CString command;
    //wkhtmltopdf.exe所在目录全路径
	CString wkhtmltopdfPath = _T("D:\\Tools\\wkhtmltopdf\\bin\\wkhtmltopdf.exe"); 
    command.Format(_T("%s \"%s\" \"%s\""), wkhtmltopdfPath,htmlFilePath, pdfFilePath);

    STARTUPINFO si;
    PROCESS_INFORMATION pi;
    ZeroMemory(&si, sizeof(si));
    ZeroMemory(&pi, sizeof(pi));
    si.cb = sizeof(si);
	si.dwFlags = STARTF_USESHOWWINDOW; //隐藏窗体
	si.wShowWindow = SW_HIDE;  //隐藏窗体

    // 创建子进程并执行命令
    BOOL result = CreateProcess(NULL, command.GetBuffer(), NULL, NULL, FALSE, 0, NULL, NULL, &si, &pi);
    if (result) {
        // 等待子进程结束
        WaitForSingleObject(pi.hProcess, INFINITE);
        CloseHandle(pi.hProcess);
        CloseHandle(pi.hThread);
    }
}

//调用
void CHpPrinterHttpDlg::OnBnClickedButton6()
{
	// TODO: 在此添加控件通知处理程序代码

	CString htmlFilePath = _T("D:\\Index.html"); //html文件路径
	CString pdfFilePath = _T("D:\\output.pdf"); //生成的pdf文件路径
	ConvertHtmlToPdf(htmlFilePath, pdfFilePath);

}

Index.html

<html>
  <head>
    <title>My HTML Document</title>
  </head>
  <body>
    <h1>Hello World!</h1>
    <h1>你好世界!</h1>
  </body>
</html>

转换的pdf中文乱码，如下图

解决方法：在html文件中添加 <meta http-equiv="content-type" content="text/html;charset=utf-8">

<html>
  <head>
    <meta http-equiv="content-type" content="text/html;charset=utf-8">
    <title>My HTML Document</title>
  </head>
  <body>
    <h1>Hello World!</h1>
    <h1>你好世界!</h1>
  </body>
</html>
