我正在使用 watson 的 NodeJS SDK 来测试 Personality Insights Service,但出现以下错误:
> Error: { Bad Request: Invalid JSON input at line 1, column 2

下面是我正在使用的代码片段:
app.get("/personality-insights", function(req, res) { const personalityInsights = new PersonalityInsightsV3({ version: '2017-10-13', authenticator: new IamAuthenticator({ apikey: watsonKeyPersonalityInsights, }), url: watsonUrlPersonalityInsights, }); let params = { content: "I am very happy today", content_type: 'text/plain', raw_scores: true, consumption_preferences: true }; personalityInsights.profile(params, function(error, response) { if (error) console.log('Error:', error); else console.log(JSON.stringify(response, null, 2)); } ); });
这是一个基于 Node JS 的示例片段,我在其中提供 API 凭证和 IBM 云提供的 URL,并使用单行输入文本发出请求。一切似乎都是正确的,但不知道为什么我会收到这个错误。
