如何在 python 中授权 gdata 联系人客户端

Question

我正在尝试使用 Google 联系人 API 向用户的联系人添加条目。我已经设法使用 OAuth2 并获得访问令牌并向 Google 联系人 API 发出授权请求。但我是手动完成的，一个简单的 GET 到 https://www.google.com/m8/feeds/contacts/default/full。我想使用 gdata 所以我不必手动创建 xml.

问题是我无法授权 gdata 的 ContactsClient。

来自文档：

gd_client = gdata.contacts.client.ContactsClient(source='YOUR_APPLICATION_NAME')
# Authorize the client.

但是如何授权呢？ example 使用电子邮件和密码创建授权的 ContactsClient

self.gd_client = gdata.contacts.client.ContactsClient(source='GoogleInc-ContactsPythonSample-1')
self.gd_client.ClientLogin(email, password, self.gd_client.source)

而目前我还没有找到如何授权gdata客户端。我确实发现我可以将 gdata.gauth.ClientLoginToken 传递给 gdata.contacts.client.ContactsClient，但效果不佳

auth_token = gdata.gauth.ClientLoginToken(credentials.access_token)
gd_client = gdata.contacts.client.ContactsClient(
     source='project-id',
     auth_token=auth_token)
contact = create_contact(gd_client)

我收到 401 - 未授权 "There was an error in your request. That's all we know"

这个create_contact来自doc

使用示例@dyerad 指示和尖晶石在 Google Contacts API doc 上创建联系人我创建了下面的示例代码。

我只需要修复从 doc 中提取的 create_contact 片段中的一个小错误。你应该使用

    # Set the contact's postal address.
    new_contact.structured_postal_address.append(gdata.data.StructuredPostalAddress(
        rel=gdata.data.WORK_REL, primary='true',
        street=gdata.data.Street(text='1600 Amphitheatre Pkwy'),
        city=gdata.data.City(text='Mountain View'),
        region=gdata.data.Region(text='CA'),
        postcode=gdata.data.Postcode(text='94043'),
        country=gdata.data.Country(text='United States')))

而不是

# Set the contact's postal address.
new_contact.structured_postal_address.append(
  rel=gdata.data.WORK_REL, primary='true',
  street=gdata.data.Street(text='1600 Amphitheatre Pkwy'),
  city=gdata.data.City(text='Mountain View'),
  region=gdata.data.Region(text='CA'),
  postcode=gdata.data.Postcode(text='94043'),
  country=gdata.data.Country(text='United States'))
