调用卸载日志进行安全卸载

admin

1、在普通安装脚本前添加库

1. 
   
2. !include "LogicLib.nsh"

复制代码

2、; 激活安装日志记录,该日志文件将会作为卸载文件的依据(注意,本区段必须放置在所有区段之前)

1. Section "-LogSetOn"
   
2. LogSet on
   
3. SectionEnd

复制代码

3、

1. /******************************
   
2. * 以下是安装程序的卸载部分 *
   
3. ******************************/
   
4. ; 根据安装日志卸载文件的调用宏
   
5. !macro DelFileByLog LogFile
   
6. ifFileExists `${LogFile}` 0 +4
   
7. Push `${LogFile}`
   
8. Call un.DelFileByLog
   
9. Delete `${LogFile}`
   
10. !macroend
    
11. Section Uninstall
    
12. !insertmacro MUI_STARTMENU_GETFOLDER "Application" $ICONS_GROUP
    
13. Delete "$INSTDIR${PRODUCT_NAME}.url"
    
14. ; 调用宏只根据安装日志卸载安装程序自己安装过的文件
    
15. !insertmacro DelFileByLog "$INSTDIRinstall.log"
    
16. ; 清除安装程序创建的且在卸载时可能为空的子目录,对于递归添加的文件目录,请由最内层的子目录开始清除(注意,不要带 /r 参数,否则会失去 DelFileByLog 的意义)
    
17. RMDir "$SMPROGRAMS$ICONS_GROUP"
    
18. SectionEnd
    
19. #-- 根据 NSIS 脚本编辑规则,所有 Function 区段必须放置在 Section 区段之后编写,以避免安装程序出现未可预知的问题。--#
