node.js - 我按照 Watson Tone 分析器的 api 文档无济于事 - 无法连接两个端点

问题描述

我有一个 Watson Tone 云服务启动并运行，我正在尝试将它链接到我的 index.js 文件。但是它似乎不想连接。

下面的代码：

const ToneAnalyzerV3 = require('watson-developer-cloud/tone-analyzer/v3');

const toneAnalyzer = new ToneAnalyzerV3({
	version: '2017-09-21',
	iam_apikey: 'omoNirDx1MUQwCdlHTQ-5Fxklx2_c0dUVAyMFIItFLty',
	url: 'http://watson-row-analyser.eu-gb.cf.appdomain.cloud/#'
});
const text =
	'Team, I know that times are tough! Product ' +
	'sales have been disappointing for the past three ' +
	'quarters. We have a competitive product, but we ' +
	'need to do a better job of selling it!';

const toneParams = {
	tone_input: { text: text },
	content_type: 'application/json'
};

toneAnalyzer
	.tone(toneParams)
	.then((toneAnalysis) => {
		console.log(JSON.stringify(toneAnalysis, null, 2));
	})
	.catch((err) => {
		console.log('error:', err);
	});

当前错误代码：

Watson 的 api 链接：

https://cloud.ibm.com/apidocs/tone-analyzer?code=node

代码 404 表示未找到。请求的项目或参数不存在。我错过了什么？
