如何使用Python获取SAP Temporary key 临时密钥

什么是Sap 临时密钥？

SAP 临时密钥是用于激活 SAP 软件的一种许可证，只能在有限的时间内使用。这些密钥可用于评估目的或在系统迁移期间使用。它们是临时解决方案，通常在一定时间后过期。

如何获取Sap Temporary keys?

临时密钥: 如果创建永久许可证密钥时出现任何错误，SAP支持门户网站提供临时的Business Objects许可证密钥。您可以通过登录到支持门户网站上的链接 www.service.sap.com/licensekey并选择“获取临时许可证密钥”链接来下载这些密钥。这些临时许可证密钥的有效期最长为90天。

方法1：手动下载

www.service.sap.com/licensekey 打开网址之后点击这里下载一个名为“bobj-temp-license-key.zip”的文件：
解压之后有一名为“SAP Analytics Emergency License Key Process”的pdf文件，在这里面可以找到你需要的License Key

方法2：使用Python自动化获取Sap Temporary keys的过程

导入需要的包

from selenium import webdriver
import time
import zipfile
import PyPDF2
import os
import shutil
import warnings

下载bobj-temp-license-key.zip

# 定义文件夹路径，替换成你想保存zip文件的路径
download_zip_path = r"C:\\Users\\USERNAME\\Projects\\download_zip"# 下载zip文件
options = webdriver.ChromeOptions()
prefs = {'profile.default_content_settings.popups': 0,'download.default_directory': download_zip_path}
options.add_experimental_option('prefs', prefs)
driver = webdriver.Chrome(chrome_options=options)
driver.get('https://support.sap.com/content/dam/support/en_us/library/ssp/my-support/keys/bobj-temp-license-key.zip')time.sleep(5)
driver.quit()

解压zip文件以获取pdf

# zip the zip file into 'bobj-temp-license-key'
file_path_zip = r"{}/bobj-temp-license-key.zip".format(download_zip_path)if os.path.exists(file_path_zip):zip_file = zipfile.ZipFile(file_path_zip)zip_file.extractall(keys_path)zip_file.close()print("解压成功")
else:print("解压失败")# 解压成功之后即可获得pdf的路径
file_path_pdf = "..."

从pdf文件中获取需要的Licence Key

以SAP BusinessObjects Tempory Licence Key为例，Licence Key位于pdf第二页的“CPU 4.2”字段之后，经过测试确定获取SAP BusinessObjects Tempory Licence Key的function：

# 获取SAP BusinessObjects Tempory Licence Key
def get_key_from_text(text):start = text.find('CPU 4.2') + 8return text[start:start + 32]

file_path_pdf为上一步中获取的pdf的路径：

if os.path.exists(file_path_pdf):pdf_file = open(file_path_pdf, 'rb')pdf_reader = PyPDF2.PdfReader(pdf_file)page = pdf_reader.pages[1]text = page.extract_text()latest_key = get_key_from_text(text)pdf_file.close()

如果每隔90天就需要更新一次license key，可以把licence key保存在一个txt文件里，成功获取最新的licence key之后可以和本地保存的licence key对比，如果latest_key != current_key，则将latest_key 替换current_key，以确保txt文件里永远保存最新的licence key。

if os.path.exists(file_path_pdf):pdf_file = open(file_path_pdf, 'rb')pdf_reader = PyPDF2.PdfReader(pdf_file)page = pdf_reader.pages[1]text = page.extract_text()latest_key = get_key_from_text(text)pdf_file.close()if latest_key != current_key:with open(current_key_txt_path, 'w') as file:file.write(latest_key)print("license已更新, latest license", latest_key)else:print("license未更新, current license:", latest_key)
else:print("PDF不存在")
