我刚刚使用Angular CLI创建了一个新的角度项目并搭建了一条新路线,我收到的错误是:

'router-outlet'不是一个已知的元素

谁能帮我 ？

是否可以在 ES 实例上设置可以控制最大客户端连接数的配置变量？最大连接数的默认限制是多少？我该如何改变它？如何使用 Elastic search 连接 logstash 以及如何重用连接。

我正在使用无服务器框架。后端为 node.js。我有几个微服务，所有其他微服务都运行良好，但现在我已经创建了我尚未使用的微服务，Axios但它仍然在控制台中抛出错误。另一个问题是，在我的本地系统中它运行良好，但是当我将其推送到服务器时，它开始产生问题。

这是抛出错误的示例代码

    const { IamAuthenticator } = require('ibm-watson/auth');
    const NaturalLanguageUnderstandingV1 = require('ibm-watson/natural-language-understanding/v1');

    async function textAnalyse(req, res) {
      const naturalLanguageUnderstanding = new NaturalLanguageUnderstandingV1({
      version: '2019-07-12',
      authenticator: new IamAuthenticator({
        apikey: 'API KEY'
      }),
    url: 'https://URL/natural-language-understanding/api'
    });

    const analyzeParams = {
       'text': HtmlToText.fromString('Test text here'),
       'features': {
         'entities': {
           'sentiment': true,
           'limit': 100
          }
        }
    };

    const analysis = await naturalLanguageUnderstanding.analyze(analyzeParams);

    // prepare the response object
    res.send({ analysis: analysis });
  }

我有图像URL,所以我通过在线转换器下载了图像并将图像转换为base 64.

那么我可以使用这个大尺寸或其他方式吗？

虽然使用ng2-translation软件包在angular2中进行动态转换,但我得到的错误如下:未处理的Promise拒绝:没有TranslateService的提供者!
