按照文档转换API示例尝试使用Flask将msword文档转换为文本，但它不起作用。
这是代码
import os, json, requests
from flask import Flask, jsonify
from watson_developer_cloud import DocumentConversionV1
app = Flask(__name__) #create flask instance
@app.route('/')
def Welcome():
v = json.loads(os.getenv('VCAP_SERVICES'))
svcName = 'document_conversion'
svc = v[svcName][0]['credentials']
url = svc['url']
user = svc['username']
password = svc['password']
document_conversion = DocumentConversionV1(username=user, password=password,version='2015-12-15')
# Example of retrieving html or plain text
with open('./doc.docx', 'rb') as document:
config = {'conversion_target': DocumentConversionV1.NORMALIZED_TEXT}
print(json.dumps(document_conversion.convert_document(document=document, config=config),indent=2))
if __name__ == "__main__":
port = os.getenv('VCAP_APP_PORT', '5000')
app.run(host='0.0.0.0', port=int(port),debug=True)
这是运行时日志
