python之reportlab生成PDF文件
项目需要,需要自动生成PDF测试报告。经过对比之后,选择使用了reportlab模块。
项目背景:开发一个测试平台,供测试维护测试用例,执行测试用例,并且生成测试报告(包含PDF和excel),将生成的测试报告以邮件的形式发送相关人。
reportlab生成PDF文件的代码如下:
from reportlab.platypus import SimpleDocTemplate, Paragraph, Spacer, Image, PageBreak, Table, TableStyle from reportlab.lib.styles import ParagraphStyle, getSampleStyleSheet from reportlab.lib.units import mm from reportlab.lib import colors from reportlab.lib.enums import TA_CENTER, TA_LEFT from reportlab.pdfbase import pdfmetrics from reportlab.pdfbase.ttfonts import TTFont pdfmetrics.registerFont(TTFont('pingbold', 'PingBold.ttf')) pdfmetrics.registerFont(TTFont('ping', 'ping.ttf')) pdfmetrics.registerFont(TTFont('hv', 'Helvetica.ttf')) #

生成样式:
需要说明的:
1.项目后台使用的是python2.7.5;
2.如果需要使用到特定的字体,需要将字体下载下来放到reportlab模块安装位置的font文件夹下,如:/xxx/python2.7/site-packages/reportlab/fonts/;
3.有官方的使用文档可以参考,如有不懂,可以下载官方说明文档查看;
4.支持表格中的中文依文字长度自动换行
