在Ubuntu 14.04上使用Python 2.7 GTK3获取GnomeKeyring键的属性 [英] Get attributes of GnomeKeyring key with Python 2.7 GTK3 on Ubuntu 14.04

问题描述

我正在使用基于Ubuntu 14.04的Linux Mint 17

I am using Linux Mint 17, based on Ubuntu 14.04

我已经安装:

python-gnomekeyring 2.3.2 python-gi 3.12 python-gtk2 2.24

python-gnomekeyring 2.3.2 python-gi 3.12 python-gtk2 2.24

我想使用GnomeKeyring.我保存并读取密钥名称和密钥密码，但是我无法访问属性.当我尝试访问它们时，我总是得到:

I want to use the GnomeKeyring. I save and read a key name an key password, but I annot access the attributes. When I try to access them I always get:

***"python"中的错误:两次释放或损坏(出)

*** Error in `python': double free or corruption (out)

这是我的代码，我今天创建了此代码以与GnomeKeyring一起使用:

Here is my code, I created this today to work with the GnomeKeyring:

推荐答案

这是可行的:

def get_attributes(self, keyring_name, key_id):
    attributes = {}
    attrs_list = GnomeKeyring.Attribute.list_new()
    (result, items )= GnomeKeyring.find_items_sync(GnomeKeyring.ItemType.GENERIC_SECRET, attrs_list)
    for item in items:
        if item.keyring == keyring_name:
            if item.item_id == key_id:
                for attr in GnomeKeyring.Attribute.list_to_glist(item.attributes):
                    if attr.name != "xdg:schema":
                        attributes[attr.name] = attr.get_string()
    return attributes
