Watson Discovery Service Python add document Error: Invalid Content-Type. Expected 'multipart/form-data'
导入 Watson Developer Cloud Python SDK
from watson_developer_cloud import DiscoveryV1
从 Slack doc_url 获取 pdf，这是私有 URL
r = requests.get(doc_url, headers={'Authorization': 'Bearer {}'.format(slack_token) })
logging.debug("read_pdf headers %s " %r.headers )
logging.debug("read_pdf content-type %s " %r.headers['content-type'] )
将文件暂时保存在云端文件系统
with open(doc_name, 'wb' ) as f:
f.write(r.content)
filepath = os.path.join(os.getcwd(), '.', doc_name )
logging.debug('filepath %s' %filepath)
logging.debug('filepath assertion %s' %os.path.isfile(filepath) )
创建发现实例
discovery = DiscoveryV1(
username=DS_USERNAME,
password=DS_PASSWORD,
version="2017-10-16"
)
在 Discovery 实例中添加 pdf 文档
with open(filepath, 'rb') as fileinfo:
add_doc = discovery.add_document(ENVIRONMENT_ID, COLLECTION_ID, file_content_type=r.headers['content-type'])
日志文件
read_pdf headers {'Content-Type': 'application/pdf', 'Content-Length': '149814'
WatsonApiException: Error: Invalid Content-Type. Expected 'multipart/form-data', got 'application/octet-stream', Code: 400 , X-dp-watson-tran-id: gateway02-732476861 , X-global-transaction-id: ffea405d5ba1ad632ba8b5bd
开发人员代码示例在 Github 中被注释掉了。

哦，天哪。那是一个悲惨的错误信息。
调用 discovery.add_document() 时缺少的是 file 参数。您可以尝试像这样添加 file=fileinfo 吗：
with open(filepath, 'rb') as fileinfo:
add_doc = discovery.add_document(ENVIRONMENT_ID,
COLLECTION_ID,
file=fileinfo,
file_content_type=r.headers['content-type'])
供参考，here is some Python code 有效并且正在做的事情与您的目标非常相似。
