用python实现vCard3.0转vCard2.1

1、环境 

Windows 7或Windows 10+ Python3.7

2、代码

'''
 Function: 将手机联系人备份从vCard3.0文件转为vCard2.1文件（旧式手机需要）
 Comment:  在Python3.7下可运行，不支持头像转换。

注：码中请删除中文后再运行。如果将上述内容使用windows记事本以非utf-8格式保存，运行时会提醒编码错误。  

3、vCard2.1样本(示例文件名：Contact2.1.vcf)

 

BEGIN:VCARD
VERSION:2.1
N;CHARSET=UTF-8;ENCODING=QUOTED-PRINTABLE:=E5=BC=A0;=E4=B8=89;;;
FN;CHARSET=UTF-8;ENCODING=QUOTED-PRINTABLE:=E5=BC=A0=E4=B8=89
TEL;CELL:1-300-756-0001
END:VCARD
BEGIN:VCARD
VERSION:2.1
N;CHARSET=UTF-8;ENCODING=QUOTED-PRINTABLE:=E6=9D=8E;=E5=9B=9B;;;
FN;CHARSET=UTF-8;ENCODING=QUOTED-PRINTABLE:=E6=9D=8E=E5=9B=9B
TEL;CELL:1-350-756-0001
END:VCARD
 

4、vCard3.0样本(示例文件名：Contact3.0.vcf)

BEGIN:VCARD
N:张;;三;;
FN:张三
TEL;CELL:139-020-12345
VERSION:3.0
UID:{12065907AB6A4B33BA359EF2A85458DF}
REV:2019-01-23 16:13:34
END:VCARD
BEGIN:VCARD
N:;;李四;;
FN:李四
TEL;HOME:123-4567
VERSION:3.0
UID:{3147AEDE309741CBA5A7906193358E14}
REV:2019-01-23 16:13:34
END:VCARD
BEGIN:VCARD
N:姓氏;名字;中间名;名称前缀;名称后缀
FN:张三
TEL;CELL:139-020-12345
VERSION:3.0
UID:{12065907AB6A4B34BA359EF2A85459DF}
REV:2019-01-23 16:13:34
END:VCARD

 

注：1、从web直接拷贝Contact3.0.vcf内容至windows记事本，每行内容可能会出现前导空白符，需要清除。

       2、最后一行要留一空行，web页面无法体现出来。
