javascript - REST请求Elasticsearch缺少身份验证 token

Question

这是我第一次在这里发布问题:我正在AngularJS中创建一个前端网站，在NodeJS中创建一个后端网站。该网站应该向我提供有关我的 flex 搜索集群的信息，并从Elasticsearch索引中获取一些信息。我尝试使用Elasticsearch Javascript API来执行请求，但是它不起作用。

我正在使用ElasticSearch 5.4

这是request的示例:

var client = new elasticsearch.Client ({

    host: 'https://noev02pe.fr:9200',
    auth: 'user:password',
    log: 'trace',
    headers: {
      'Authorization': 'Basic user:password',
     }
});

export function connect() {
  client.search({
    index: 'metric-prod*',
    q: 'kafka'
  }
, function (error, response) {
    console.log(response);
  });
}

控制台上的响应是:

{ error:
    { root_cause: [ [Object] ],
      type: 'security_exception',
      reason: 'missing authentication token for REST request [/metric-
      prod*/_search?q=kafka]',
      header: { 'WWW-Authenticate': 'Basic realm="security" charset="UTF-8"' 
    } },
  status: 401 }

我也尝试做经典的帖子请求:

   export function createUser(request,response,next){
      var username = request.params.username;
      var userData = querystring.stringify(request.body);
      console.log(userData);
      var options ={
       hostname: 'noev02vr.fr',
       port: 9200,
        rejectUnauthorized: false,
        path: "_xpack/security/user/"+username,
    method:'POST',
    headers: {
      'Authorization': 'Basic ' + prodPass,
      'Content-Type': 'application/json',
      'Content-Length': userData.length
    }
  };



 var post_req=http.request(options, function(res){
            console.log('post user reussi');
            res.on('data', function(data){

             response.writeHead(res.statusCode);
             response.write(data);
             console.log(res.statusCode);
           });

         });

          post_req.write(userData);
          post_req.end();

       }

我得到一个500错误。

基本认证

const { Client } = require('@elastic/elasticsearch')
const client = new Client({
  node: 'https://localhost:9200', //Replace with your URL.
  auth: { 
    username: 'elastic',
    password: '*****' //Replace with your password
  }
})

否则，您可以在节点URL中提供您的凭据

const { Client } = require('@elastic/elasticsearch')
const client = new Client({
  node: 'https://username:password@localhost:9200'
})

如果您启用了ssl，则这是配置

const { Client } = require('@elastic/elasticsearch')
const client = new Client({
  node: 'https://localhost:9200',
  auth: {
    username: 'elastic',
    password: '*****'
  },
  ssl: {
    ca: fs.readFileSync('./cacert.pem'),
    rejectUnauthorized: false
  }
})
