我是 Python 和 Flask 的新手...我开发了一个 python 文件,它使用 googele 设置 Oauth2 身份验证并从 GMAIL API 获取消息列表。这是我的代码
import json
import flask
import httplib2
import base64
import email
from apiclient import discovery, errors
from oauth2client import client
app = flask.Flask(__name__)
@app.route('/')
def index():
if 'credentials' not in flask.session:
return flask.redirect(flask.url_for('oauth2callback'))
credentials = client.OAuth2Credentials.from_json(flask.session['credentials'])
if credentials.access_token_expired:
return flask.redirect(flask.url_for('oauth2callback'))
else:
http_auth = credentials.authorize(httplib2.Http())
gmail_service = discovery.build('gmail', 'v1', http_auth)
threads = gmail_service.users().threads().list(userId='me').execute()
return json.dumps(threads)
@app.route('/oauth2callback')
def oauth2callback():
flow = client.flow_from_clientsecrets(
'client_secrets.json',
scope='https://mail.google.com/',
redirect_uri=flask.url_for('oauth2callback', _external=True)
)
if 'code' not in flask.request.args:
auth_uri = flow.step1_get_authorize_url()
return flask.redirect(auth_uri)
else:
auth_code = flask.request.args.get('code')
credentials = flow.step2_exchange(auth_code)
flask.session['credentials'] = credentials.to_json()
return flask.redirect(flask.url_for('index'))
@app.route('/getmail')
def getmail():
if 'credentials' not in flask.session:
return flask.redirect(flask.url_for('oauth2callback'))
credentials = client.OAuth2Credentials.from_json(flask.session['credentials'])
if credentials.access_token_expired:
return flask.redirect(flask.url_for('oauth2callback'))
else:
http_auth = credentials.authorize(httplib2.Http())
gmail_service = discovery.build('gmail', 'v1', http_auth)
query = 'is:inbox'
"""List all Messages of the user's mailbox matching the query.
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.
query: String used to filter messages returned.
Eg.- 'from:user@some_domain.com' for Messages from a particular sender.
Returns:
List of Messages that match the criteria of the query. Note that the
returned list contains Message IDs, you must use get with the
appropriate ID to get the details of a Message.
"""
try:
response = gmail_service.users().messages().list(userId='me', q=query).execute()
messages = []
if 'messages' in response:
print 'test %s' % response
messages.extend(response['messages'])
while 'nextPageToken' in response:
page_token = response['nextPageToken']
response = gmail_service.users().messages().list(userId='me', q=query, pageToken=page_token).execute()
messages.extend(response['messages'])
return messages
except errors.HttpError, error:
print 'An error occurred: %s' % error
if __name__ == '__main__':
import uuid
app.secret_key = str(uuid.uuid4())
app.debug = True
app.run()
身份验证工作正常,当我转到 /getmail
URL 时,我收到此错误 TypeError: 'list' object is not callable
有什么想法我做错了吗?
最佳答案
我将 Flask 中的返回对象从返回消息
更改为这段代码。
首先我导入到 fromflask.json import jsonify
try:
response = gmail_service.users().messages().list(userId='me', q=query).execute()
messages = []
if 'messages' in response:
print 'test %s' % response
messages.extend(response['messages'])
while 'nextPageToken' in response:
page_token = response['nextPageToken']
response = gmail_service.users().messages().list(userId='me', q=query, pageToken=page_token).execute()
messages.extend(response['messages'])
return jsonify({'data': messages}) # changed here
except errors.HttpError, error:
print 'An error occurred: %s' % error
所有功劳都归功于@doru
