我是reportlab的初学者，在构建pdf时遇到了一个奇怪的问题。MyFirstPage 模板覆盖 myLaterPages。

def myFirstPage(canv, doc):
  canv.saveState()  
  canv.line(left_margin, top_margin, right_margin, top_margin)
  canv.setFont('Times-Italic',12)
  canv.drawString(right_margin - 100, top_margin + 10, "Report")
  canv.drawImage('logo.jpg', left_margin, top_margin, width = 90, height= 30)
  canv.setFont("Times-Bold", 36)
  canv.drawCentredString(0.5 * A4[0], 7 * inch, "Rapport journalier d activite")
  canv.line(left_margin, top_margin, right_margin, top_margin)
  canv.line(left_margin, bottom_margin, right_margin, bottom_margin)
  canv.drawCentredString(0.5*A4[0], 0.5 * inch,"Page %d" % canv.getPageNumber())
  canv.restoreState()


def myLaterPages(canv, doc):
  canv.saveState()  
  canv.line(left_margin, top_margin, right_margin, top_margin)
  canv.setFont('Times-Italic',12)
  canv.drawString(right_margin - 100, top_margin + 10, "Report")
  canv.drawImage('logo.jpg', left_margin, top_margin, width = 90, height= 30)
  canv.line(left_margin, top_margin, right_margin, top_margin)
  canv.line(left_margin, bottom_margin, right_margin, bottom_margin)
  canv.drawCentredString(0.5*A4[0], 0.5 * inch,"Page %d" % canv.getPageNumber())
  canv.restoreState()

def create_pdf_report(pdfname = 'report.pdf'):
  code = [200, 404]
  app = ['webserver01, webserver02']
  doc =   SimpleDocTemplate(pdfname,rightMargin=5,leftMargin=5,topMargin=0,bottomMargin=5)   
  result = []
  for a in app:
    result.append(Spacer(1, 70))
    result.append(create_table_website_ref(a))
    result.append(create_pi_graphic(a))
    result.append(Spacer(1, 30))
    for i in code:
        result.extend(create_table_graph_row(a, i))
        result.append(Spacer(1, 30))
    result.append(PageBreak())
doc.build(result, onFirstPage=myFirstPage , onLaterPages=myLaterPages)

谢谢

后

doc = SimpleDocTemplate(pdfname,rightMargin=5,leftMargin=5,topMargin=0,bottomMargin=5) 你必须添加frame和template部分，doc 例如

frame = Frame(doc.leftMargin, doc.bottomMargin, doc.width, doc.height, id='normal')
    template = PageTemplate(frames=frame, onPage=header)
    doc.addPageTemplates([template])

这将在呈现 pdf 时添加您的第一页。result.append(NextPageTemplate('header')) 现在，在渲染第二页的内容之前添加稍后的页面模板插入 。
