people.connections.list没有返回使用Python客户端库

Question

我试图以编程方式访问使用Python客户端库我自己的个人帐户谷歌联系人列表中的联系人

这是将上运行脚本服务器没有用户输入，所以我设置了使用来自我设置的服务帐户的凭证。我的Google API控制台设置看起来像这样。

我用下面简单的脚本，从API文档中提供的例子拉 -

import json 
from httplib2 import Http 

from oauth2client.service_account import ServiceAccountCredentials 
from apiclient.discovery import build 

# Only need read-only access 
scopes = ['https://www.googleapis.com/auth/contacts.readonly'] 

# JSON file downloaded from Google API Console when creating the service account 
credentials = ServiceAccountCredentials.from_json_keyfile_name(
    'keep-in-touch-5d3ebc885d4c.json', scopes) 

# Build the API Service 
service = build('people', 'v1', credentials=credentials) 

# Query for the results 
results = service.people().connections().list(resourceName='people/me').execute() 

# The result set is a dictionary and should contain the key 'connections' 
connections = results.get('connections', []) 

print connections #=> [] - empty! 

当我打的API返回，没有任何“关系”的结果集键。具体而言，它返回 -

>>> results 
{u'nextSyncToken': u'CNP66PXjKhIBMRj-EioECAAQAQ'} 

是否有某些与我的设置或代码有关的错误？有没有办法查看响应HTTP状态代码或获取关于它想要做什么的更多细节？

谢谢！

旁注：当我尝试使用the "Try it!" feature in the API docs，它正确返回我的联系人。虽然我怀疑是否使用客户端库，而是依赖于通过OAuth进行的用户授权

Answer 1

personFields mask是必需的。指定一个或多个有效路径。有效的路径记录在https://developers.google.com/people/api/rest/v1/people.connections/list/。

此外，使用字段掩码指定哪些字段包含在部分响应中。

相反的：

results = service.people().connections().list(resourceName='people/me').execute() 

...尝试：

results = service.people().connections().list(resourceName='people/me',personFields='names,emailAddresses',fields='connections,totalItems,nextSyncToken').execute() 

Answer 2

随着服务帐户，在DWD - 摹套房域范围内的代表团，在这种方式

必要模仿或委派用户

delegate = credentials.create_delegated('user@xxxx.xxx') 

Answer 3

这里是一个工作演示。我现在只是测试它。 Python 3.5.2

google-api-python-client==1.6.4 
httplib2==0.10.3 
oauth2client==4.1.2 

你可以将它保存到demo.py然后运行它。我离开了create_contact函数，以防您可能想要使用它，并且还有一个关于API使用情况的示例。

CLIENT_ID和CLIENT_SECRET是环境变量，所以我不小心共享代码。
