我從哪裏獲得授權的Gmail API服務實例？ （python，gmail api）

Question

我正在嘗試從我的gmail api代碼調用，因此我可以創建一個草稿，但我無法弄清楚在哪裏獲得「授權的Gmail API服務實例」。以下是我的代碼：

def CreateDraft(service, user_id, message_body): 
    CreateDraft('SERVICE THING NEEDS TO BE HERE','me','thisisbody') 
    """Create and insert a draft email. Print the returned draft's message and id. 

    Args: 
    service: Authorized Gmail API service instance. 
    user_id: User's email address. The special value "me" 
    can be used to indicate the authenticated user. 
    message_body: The body of the email message, including headers. 

    Returns: 
    Draft object, including draft id and message meta data. 
    """ 
    try: 
    message = {'message': message_body} 
    draft = service.users().drafts().create(userId=user_id, body=message).execute() 

    print 'Draft id: %s\nDraft message: %s' % (draft['id'], draft['message']) 

    return draft 
    except errors.HttpError, error: 
    print 'An error occurred: %s' % error 
    return None 

有誰知道哪裏可以找到授權的Gmail API服務實例？我有一個客戶ID和祕密，但這與該權利沒有關係？

所以我想通了。我做了以下內容：

1）變化範圍來：

SCOPES = 'https://mail.google.com/' 

2）在您的計算機（Windows 7）進入「C：\用戶\ YOURUSERNAME \ .credentials

3）刪除文件 「的Gmail - 快速入門」

4）再次運行該代碼（quickstart.py）

5）當消息在瀏覽器中彈出，點擊接受。

6）檢查郵件，如果你想通過api發送郵件，你應該在那裏留言。

憑證文件似乎擁有權限。更改您的權限然後刪除該文件似乎使所有工作都完美無缺。所以，總體來說你的代碼應該是這個樣子，如果你正在尋找通過API來發送郵件：

我一直在試圖弄清楚這一點在過去幾天和整個這個線程偶然，因爲它是專門我遇到的服務部分 - 我從事這個工作的例子不包括這部分。

我無法讓ragnampiza的代碼在剪切和粘貼時工作，但設法從各種來源獲得解決方案，包括這個。

我最終發佈了一個解決方案，其中涵蓋了身份驗證，創建基本消息，獲取憑據，獲取服務以及最終發送消息。如果有任何幫助，請點擊此處：https://github.com/chris-brown-nz/python-gmail-api
