不会从 .vcf 文件中读取多个 vcard，vobject.readOne(f) 仅适用于第一个 vcard

Question

    #!/usr/bin/env python2.7

    import vobject

    abfile='/foo/bar/directory/file.vcf'

    def test_vobject_dot_readOne():
        with open(abfile) as f:
            vcard = vobject.readOne(f)
            vcard = vobject.readOne(f)

    test_vobject_dot_readOne()

上面的代码不起作用，但如果我们删除两个重复语句中的一个，它会起作用。我想一张一张地阅读电子名片。有没有办法用 vobject.readOne(f) 做到这一点？如何从文件中读取 vcard n？

我使用的 vcf 文件取自 google 联系人（导出为 vcard 格式）。这是我在测试中使用的文件内容，只有两个 vcard：

    BEGIN:VCARD 
    VERSION:3.0
    FN:Foo_bar1
    N:;Foo_bar1;;;
    EMAIL;TYPE=INTERNET:foobar1@foo.bar.com
    END:VCARD
    BEGIN:VCARD
    VERSION:3.0
    FN:Foo_bar2 
    N:;Foo_bar2;;;
    EMAIL;TYPE=INTERNET:foobar2@foo.bar.com
    END:VCARD

然后可以使用 Vcard 读数进行比较以避免重复，如另一个问题所示：

To remove vcard contact duplicates, comparing if two vcards are equal in .vcf file does not work with simple == vobject comparison

好吧，希望我能正确理解你想要做什么。

您是否正在尝试做这样的事情？

#!/usr/bin/env python2.7

import vobject

test_vcard_information = r"""BEGIN:VCARD
VERSION:3.0
FN:Foo_bar1
N:;Foo_bar1;
EMAIL;TYPE=INTERNET:foobar1@foo.bar.com
END:VCARD
BEGIN:VCARD
VERSION:3.0
FN:Foo_bar2
N:;Foo_bar2;
EMAIL;TYPE=INTERNET:foobar2@foo.bar.com
END:VCARD
"""

for vcard in vobject.readComponents(test_vcard_information):
    print vcard.fn.value

或者，如果您有文件中的信息：

#!/usr/bin/env python2.7

import vobject

test_filename = r'/path/to/Test_addressbook.vcf'

with open(test_filename) as source_file:
    for vcard in vobject.readComponents(source_file):
       print vcard.fn.value

您可能会将.readOne() 与日历文件 (.ics) 一起使用，因为它将由单个根对象组成，如下例所示：

#!/usr/bin/env python2.7

import vobject
