我使用Google DFP API来收集点击我们网站上的广告的一些统计数据。代码是用Python编写的。目前,我想升级的代码使用OAuth 2
因为,代码每天自动运行,无需任何用户参与,我在我的谷歌项目创建一个
服务帐户和添加的帐户使用DoubleClick for
出版商我们公司的网络。基于WEB的样本代码,我写了这个:在Python中使用服务帐户创建DfpClient

import httplib2 
from oauth2client.client import SignedJwtAssertionCredentials 
from apiclient.discovery import build 
from googleads.dfp import DfpClient 

GOOGLE_DFP_SCOPE="https://www.googleapis.com/auth/dfp" 
API_VERSION="v201411" 
KEY_FILE="*******.p12" 
ACCT_EMAIL="************************@developer.gserviceaccount.com" 
NETWORK_CODE="**********" 
with open(KEY_FILE) as config_file: 
    my_private_key = config_file.read() 
credentials = SignedJwtAssertionCredentials(service_account_name=ACCT_EMAIL, private_key=my_private_key,scope=GOOGLE_DFP_SCOPE) 
http = httplib2.Http() 
http_auth = credentials.authorize(http) 
dfp_client = build(serviceName='dfp',version=API_VERSION,http=http_auth) 

此代码似乎并不正确,因为network_code未获通过 在代码的任何地方。另外,它失败并显示以下消息:

apiclient.errors.UnknownApiNameOrVersion:name:dfp version:v201411。

此外,线下:

dfp_client = DfpClient.LoadFromStorage() 

不适合我的情况下工作,因为,这是基于googleads.yaml这似乎 只为web应用程序账户的客户端秘密进行格式化,不是P12私钥。

有什么建议吗?谢谢。

Apiclient.discovery使用默认的route来检查服务。 但我没有找到适用于发布商的DoubleClick服务。

我使用此代码与Oauth2一起使用API​​。使用Flask

import json 
import requests 
import flask 

from googleads import dfp 
from googleads import oauth2 

app = flask.Flask(__name__) 

CLIENT_ID = '' 
CLIENT_SECRET = '' # Read from a file or environmental variable in a real app 
SCOPE = 'https://www.googleapis.com/auth/dfp' 
REDIRECT_URI = '' 
APPLICATION_NAME = 'DFP API SERVICE' 
NETWORK_CODE = '' 


@app.route('/') 
def index(): 

    if 'credentials' not in flask.session: 
     return flask.redirect(flask.url_for('oauth2callback')) 
    credentials = json.loads(flask.session['credentials']) 
    if credentials['expires_in'] <= 0: 
     return flask.redirect(flask.url_for('oauth2callback')) 
    else: 
     try: 
      refresh_token = credentials['refresh_token'] 
      oauth2_client = oauth2.GoogleRefreshTokenClient(CLIENT_ID, CLIENT_SECRET, refresh_token) 
      dfp_client = dfp.DfpClient(oauth2_client, APPLICATION_NAME, NETWORK_CODE) 
      user_service = dfp_client.GetService('UserService', version='v201508') 
      user = user_service.getCurrentUser() 
      return flask.render_template('index.html', name=user['name']) 
     except: 
      flask.session.pop('credentials', None) 
      return flask.redirect(flask.url_for('oauth2callback')) 

@app.route('/oauth2callback') 
def oauth2callback(): 
    if 'code' not in flask.request.args: 
     auth_uri = ('https://accounts.google.com/o/oauth2/auth?response_type=code' 
       '&access_type=offline&client_id={}&redirect_uri={}&scope={}&').format(CLIENT_ID, REDIRECT_URI, SCOPE) 
     return flask.redirect(auth_uri) 
    else: 
     auth_code = flask.request.args.get('code') 
     data = {'code': auth_code, 
      'client_id': CLIENT_ID, 
      'client_secret': CLIENT_SECRET, 
      'redirect_uri': REDIRECT_URI, 
      'grant_type': 'authorization_code'} 
     r = requests.post('https://www.googleapis.com/oauth2/v3/token', data=data) 
     flask.session['credentials'] = r.text 
     return flask.redirect(flask.url_for('index')) 

if __name__ == '__main__': 
    import uuid 
    app.secret_key = str(uuid.uuid4()) 
    app.debug = False 
    app.run() 

我希望这可以帮助您

你是正确的。您在创建dfp客户端时必须传递网络代码。版本是没有必要的。尝试下面的代码在python中创建客户端。

import os 

from googleads import oauth2 
from googleads import dfp 

def get_dfp_client(): 
    application_name = "Your application name" # from google developer console. eg: Web Client 
    network_code = ******** 
    private_key_password = 'notasecret' 
    key_file = os.path.join('path/to/p12file') 
    service_account_email = '****@***.iam.gserviceaccount.com' 
    # create oath2 client(google login) 
    oauth2_client = oauth2.GoogleServiceAccountClient(
     oauth2.GetAPIScope('dfp'), service_account_email, key_file) 

    dfp_client = dfp.DfpClient(oauth2_client, application_name, network_code) 
    return dfp_client 

client = get_dfp_client()
