※ 部份環境中文字會有亂碼產生，故_html.getBytes() =>  _html.getBytes("UTF-8") 排除

※ 部份環境無法讀取TTC 選TTF字型檔可以排除

// PDF設定縮放

PdfDestination pdfDest = new PdfDestination(PdfDestination.XYZ, 0, document.getPageSize().getHeight(), 0.8f);

PdfAction action = PdfAction.gotoLocalPage(1, pdfDest, pdfWriter);

pdfWriter.setOpenAction(action);

Maven Get Html Content use HttpPost

//url: target url address
//id: post include params

                   //if use https or call https url addr than show handshake failed return, can add in pass check
SSLContext sslcontext = SSLContexts.createDefault();
SSLConnectionSocketFactory sslsf = new 
              SSLConnectionSocketFactory(sslcontext, new String[] { "TLSv1.2"}, null, new NoopHostnameVerifier());
CloseableHttpClient httpClient = HttpClients.custom().setSSLSocketFactory(sslsf).build();
        
        try {        
    //Use HttpGet method 
    //HttpGet webGet = new HttpGet(url);
                            //Use HttpPost method 
    HttpPost webGet = new HttpPost(url); 
    ArrayList<BasicNameValuePair> params = new ArrayList<BasicNameValuePair>( );
    params.add(new BasicNameValuePair("id" ,id )) ;
    webGet.setEntity(new UrlEncodedFormEntity(params));
    
    CloseableHttpResponse response = httpClient.execute(webGet);
    HttpEntity entity = response.getEntity();
    content = EntityUtils.toString(entity, "UTF-8");
    content = content.replace("&emsp;", "<font color='white'>＿</font>");
    //System.out.println(content);
    EntityUtils.consume(entity);
} catch (Exception ex) {
log.error(ex.getMessage(), ex);
} finally {
