Watson Discovery API的add_document方法出错

Question

我尝试将此代码与Discovery API结合使用，但出现一个奇怪的错误。 似乎发现无法识别我的简单HTML并拒绝了它。 我尝试了很多简单的HTML文件，但没有用：

import sys
import os
import json
from watson_developer_cloud import DiscoveryV1


discovery = DiscoveryV1(version="2018-10-15", url='https://gateway.watsonplatform.net/discovery/api', username=username, password=password)



with open((os.path.join(os.getcwd(), 'html_simple_file.html')), "r") as fileinfo:
    add_doc = discovery.add_document(Environment_Id,
                                     Collection_Id,
                                     file_info=fileinfo,
                                    file_content_type = "text/html")
print(json.dumps(add_doc, indent=2))




 --------------------------------------------------------------------------- WatsonApiException Traceback (most recent call last) in () 13 Collection_Id, 14 file_info=fileinfo, ---> 15 file_content_type = "text/html") 16 print(json.dumps(add_doc, indent=2))

    489             raise WatsonApiException(response.status_code, error_message,
--> 490                                      info=error_info, httpResponse=response)

我不明白它是如何工作的。 感谢您的任何帮助！

问题在于公开调用，您需要在其中传递文件名（.html）的文件路径。 这是工作代码

import os
import json
from watson_developer_cloud import DiscoveryV1

discovery = DiscoveryV1(
    version="2018-10-15",
    username='{USERNAME}',
    password='{PASSWORD}',
    #iam_apikey='{apikey}',
    url='https://gateway.watsonplatform.net/discovery/api'
)

with open(os.path.join(os.getcwd(), '/Users/VMac/Downloads/', 'Ana.json.html')) as fileinfo:
    add_doc = discovery.add_document('{DISCOVERY_ENVIRONMENT_ID}', '{DISCOVERY_COLLECTION_ID}', file=fileinfo).get_result()
print(json.dumps(add_doc, indent=2))

在上面的代码中传递了所有必需的详细信息之后，这是输出

{
  "document_id": "6439d5f2-f273-4173-8d25-54dc934df",
  "status": "processing"
}
