Watson User Modeling 服务 returns 错误“从 VCAP_SERVICES 读取时无法读取未定义的属性 '0'

Question

Watson User Modeling 服务似乎已从我的应用程序中删除。我的应用程序出现以下错误。

发生了什么事，我需要做什么来解决这个问题？

Answer 1

最近重命名了用户建模服务。现在是人格洞察力。我通过将新的 Personality Insights 服务添加到我的应用程序并更新我的阅读代码来解决此问题 VCAP_SERVICES.

而不是执行以下操作：

var VCAP_SERVICES = process.env["VCAP_SERVICES"],
    vcapServices;

if (VCAP_SERVICES) {
    vcapServices = JSON.parse(VCAP_SERVICES);
}

return vcapServices["user_modeling"][0].credentials.url;

改为执行以下操作。注意 user_modeling 与 personality_insights.

有关

var VCAP_SERVICES = process.env["VCAP_SERVICES"],
    vcapServices;

if (VCAP_SERVICES) {
    vcapServices = JSON.parse(VCAP_SERVICES);
}

return vcapServices["personality_insights"][0].credentials.url;

此外，API 发生了一些变化...URL 现在是您从 VCAP_SERVICES + /v2/profile 获得的 URL。这是 VCAP_SERVICES + /api/v2/profile

更确切地说 vcapServices["personality_insights"][0].credentials.url + "/v2/profile"。
