WatsonApiException: Error: Unauthorized: Access is denied due to invalid credentials , Code: 401

Question

我正在尝试根据 docs:

连接到语言翻译器实例

!pip install --upgrade "watson-developer-cloud>=1.4.0"

import json
from watson_developer_cloud import LanguageTranslatorV2

translator = LanguageTranslatorV2(
    iam_api_key='***my_api_key***',
    url='https://gateway.watsonplatform.net/language-translator/api'
)

models = translator.list_models()
print(json.dumps(models, indent=2))

但是，这会导致：

WatsonApiException: Error: Unauthorized: Access is denied due to invalid credentials , Code: 401 , Information: {'description': 'No credentials supplied.'} , X-dp-watson-tran-id: xxxxxx , X-global-transaction-id: xxxxx

我在服务凭证中找到了 API 密钥。我尝试了 apikey 和 iam_apikey_name 但都导致了相同的错误：

{
 “apikey”: “***my_api_key***”,
 “iam_apikey_description”: “Auto generated apikey during resource-key operation for Instance - crn:v1:bluemix:public:language-translator:us-south:xxxxxx::“,
 “iam_apikey_name”: “auto-generated-apikey-xxxxxx",
 “iam_role_crn”: “crn:v1:bluemix:public:iam::::serviceRole:Manager”,
 “iam_serviceid_crn”: “crn:v1:bluemix:public:iam-identity::xxxxxx::serviceid:ServiceId-xxxxxx",
 “url”: “https://gateway.watsonplatform.net/language-translator/api”
}

我还尝试为 IBM Cloud 创建平台 API 密钥。同样的错误。

我还尝试创建一个访问令牌：

%%bash
curl -k -X POST \
  --header "Content-Type: application/x-www-form-urlencoded" \
  --header "Accept: application/json" \
  --data-urlencode "grant_type=urn:ibm:params:oauth:grant-type:apikey" \
  --data-urlencode "apikey=**myapikey**" \
  "https://iam.bluemix.net/identity/token"

然后使用 curl 返回的访问令牌：

translator = LanguageTranslatorV2(iam_access_token='**generated_access_token**')

同样的错误:(

我认为这个问题类似于针对 VisualRecognition 发布的 question，但在本例中是针对 LanguageTranslator。

Answer 1

语言翻译器现在有 V3 版本的服务。也许您创建了一个 V3 服务实例？如果是这样，您需要使用 Watson Python SDK 中的 LanguageTranslatorV3 模块。
