Python平臺(tái)的優(yōu)秀PDF報(bào)表類庫(kù)Reportlab。它不屬于Python的標(biāo)準(zhǔn)類庫(kù)，所以必須手動(dòng)下載類庫(kù)包并安裝：

yum install python-reportlab -y

這篇文章將介紹reportlab中基本常用的api，使用canvas畫出一份整潔的PDF報(bào)表。詳細(xì)內(nèi)容參考reportlab的官方user guide。

示例一、生成一段文字#!/usr/bin/python

from?reportlab.pdfgen?import?canvas

def?hello():

c?=?canvas.Canvas("helloworld.pdf")

c.drawString(100,100,"Hello,World")

c.showPage()

c.save()

hello()

示例二、生成單個(gè)文件的pdf#需要安裝字體?yum?install?wqy-*?-y

#!/usr/bin/python

import?datetime

import?subprocess

import?codecs

from?reportlab.pdfgen?import?canvas

from?reportlab.lib.units?import?inch

from?reportlab.lib.pagesizes?import?A4,?landscape

import?reportlab.pdfbase.ttfonts

reportlab.pdfbase.pdfmetrics.registerFont(reportlab.pdfbase.ttfonts.TTFont('song',?'/usr/share/fonts/cn/msjh.ttf'))

import?reportlab.lib.fonts

def?disk1_report():

p1?=?subprocess.Popen("cat?cmd1.log?",shell=True,stdout=subprocess.PIPE)

return?p1.stdout.readlines()

def?create_pdf(input,output="disk1.pdf"):

now?=?datetime.datetime.today()

date?=?now.strftime("%h?%d?%Y?%H:%M:%S")

c?=?canvas.Canvas(output,pagesize=A4)

c.setFont('song',10)

textobject?=?c.beginText()

textobject.setTextOrigin(1*inch,11*inch)

textobject.textLines('''Disk?Capacity?Report:?%s?'''?%?date?)

for?line?in?input:

textobject.textLine(line.strip())

c.drawText(textobject)

c.showPage()

c.save()

report?=?disk1_report()

create_pdf(report)

示例三、循環(huán)生成指定目錄下的多個(gè)文件()#!/usr/bin/python

import?os

import?os.path

import?datetime

import?subprocess

from?reportlab.lib.pagesizes?import?A4,?landscape

from?reportlab.pdfgen?import?canvas

from?reportlab.lib.units?import?inch

logdir?=?"/var/www/device/check_log"

for?root,dirs,filenames?in?os.walk(logdir):

for?filename?in?filenames:

v?=?root+os.sep+filename

os.environ['file']?=?str(v)

def?disk_report():

p?=?subprocess.Popen("cat?$file?",shell=True,stdout=subprocess.PIPE)

return?p.stdout.readlines()

def?create_pdf(input,output="/var/www/device/check_pdf/"+filename+".pdf"):

now?=?datetime.datetime.today()

date?=?now.strftime("%h?%d?%Y?%H:%M:%S")

c?=?canvas.Canvas(output,pagesize=A4)

textobject?=?c.beginText()

textobject.setTextOrigin(1*inch,11*inch)

textobject.textLines('''Disk?Capacity?Report:?%s?'''?%?date?)

for?line?in?input:

textobject.textLine(line.strip())

c.drawText(textobject)

c.showPage()

c.save()

report?=?disk_report()

create_pdf(report)
