python中的GoogleAppClient，使用updateContact返回403

Question

我正试图从谷歌的API获取联系人列表，然后更新其中的一些联系人。在运行updateContact函数时，我每次都会收到403个错误Request person.etag is different than the current person.etag. Clear local cache and get the latest person."。
我正在使用以下代码读取联系人的etag：

service = build('people', 'v1', credentials=creds)
results = service.people().connections().list(
        resourceName='people/me',
        pageSize=100,
        personFields='names,emailAddresses').execute()
connections = results.get('connections', [])

然后，对于connections中的每个contact，我尝试更改联系人的givenName和familyName：

service.people().updateContact(resourceName="contact's resource name",
                              updatePersonFields="names",
                              body={
                                  "etag": "contact's etag",
                                  "names": [
                                    {
                                      "familyName": "new family name",
                                      "givenName": "new given name"
                                    }
                                  ]
                                }
                              ).execute()

联系人的etag和resourceName来自连接的列表响应。
例如：

print(connections[0])
{'resourceName': 'people/<resource_number>',
 'etag': 'etag string',
 'names': [{'metadata': {'primary': True,
    'source': {'type': 'CONTACT', 'id': 'id number'}},
   'displayName': 'x',
   'familyName': 'x',
   'givenName': 'x',
   'displayNameLastFirst': 'x',
   'unstructuredName': 'x'}]}

Answer 1

运行准确的代码确实有效

我运行了您的代码并基于Google People Python Quickstart，同时只更改了两件事：

1. 权限

2. 添加代码

   SCOPES = ['https://www.googleapis.com/auth/contacts']
   
   ...
   
   service = build('people', 'v1', credentials=creds)
   
   results = service.people().connections().list(
       resourceName='people/me',
       pageSize=5,
       personFields='names,emailAddresses').execute()
   connections = results.get('connections', [])
   
   for contact in connections:
       service.people().updateContact(resourceName=contact['resourceName'],
                                      updatePersonFields="names",
                                      body={
                                          "etag": contact['etag'],
                                          "names": [
                                              {
                                                  "familyName": "new family name",
                                                  "givenName": "new given name"
                                              }
                                          ]
                                      }
                                      ).execute()
