我无法在 Python 客户端中使用下载报告功能。我正在使用带有 v201306 的 adwords-15.9.0。它总是失败：
$ ./classifications.py
Traceback (most recent call last):
File "./classifications.py", line 48, in <module>
download_report(client, client_id)
File "./classifications.py", line 32, in download_report

headers['Authorization'] = 'Bearer ' + self.access_token
TypeError: cannot concatenate 'str' and 'NoneType' objects
示例脚本get_report_fields.py和get_campaign_stats.py工作正常，但download_criteria_report.py和download_criteria_report_with_awql.py失败并出现相同的错误。
有任何想法吗？
我的代码：
