node.js - azure 的阿尔戈利亚

Question

我正在为我的 Android 应用程序使用 firebase，并使用所有博客建议的 Algolia 执行全文搜索。我已经成功开发了该脚本并且其功能正常。现在我想托管脚本以 24* 运行 7. 由于我有一个 azure 帐户，我如何上传脚本？我尝试将以下内容作为函数、网络应用程序上传，但没有成功。

PS:- 我尝试过 Heroku 但不满意。

脚本。

var http = require('http');
var port = process.env.port || 1337;
http.createServer(function (req, res) {
    res.writeHead(200, { 'Content-Type': 'text/plain' });
    res.end('Hello World\n');
}).listen(port);
    var dotenv = require('dotenv');
var firebaseAdmin = require("firebase-admin");
var algoliasearch = require('algoliasearch');
var algoliasearchHelper = require('algoliasearch-helper');


// load values from the .env file in this directory into process.env
dotenv.load();

// configure firebase
var serviceAccount = require("./serviceAccountKey.json");
firebaseAdmin.initializeApp({
  credential: firebaseAdmin.credential.cert(serviceAccount),
  databaseURL: process.env.FIREBASE_DATABASE_URL
});
var database = firebaseAdmin.database();

// configure algolia
var algolia = algoliasearch(process.env.ALGOLIA_APP_ID, process.env.ALGOLIA_API_KEY);
var index = algolia.initIndex('books');

var contactsRef = database.ref("/BookFair");

contactsRef.on('child_added', addOrUpdateIndexRecord);
contactsRef.on('child_changed', addOrUpdateIndexRecord);
contactsRef.on('child_removed', deleteIndexRecord);

function addOrUpdateIndexRecord(dataSnapshot) {
  // Get Firebase object
  var firebaseObject = dataSnapshot.val();
  // Specify Algolia's objectID using the Firebase object key
  firebaseObject.objectID = dataSnapshot.key;
  // Add or update object
  index.saveObject(firebaseObject, function(err, content) {
    if (err) {
      throw err;
    }
    console.log('Firebase object indexed in Algolia', firebaseObject.objectID);
  });
}

function deleteIndexRecord(dataSnapshot) {
  // Get Algolia's objectID from the Firebase object key
  var objectID = dataSnapshot.key;
  // Remove the object from Algolia
  index.deleteObject(objectID, function(err, content) {
    if (err) {
      throw err;
    }
    console.log('Firebase object deleted from Algolia', objectID);
  });
}

var queries = database.ref("/queries");

queries.on('child_added', addOrUpdateIndexRecordN);

function addOrUpdateIndexRecordN(dataSnapshot) {
  // Get Firebase object
  var firebaseObject = dataSnapshot.val();
  // Specify Algolia's objectID using the Firebase object key
  firebaseObject.objectID = dataSnapshot.key;
  // Add or update object

  var collegeName = "";
  var query_ID_LOLWA= "";
  var year="";
  var query = "";
  var counter = 0;

  for(var i in firebaseObject){
      var c = firebaseObject.charAt(i);
      if(c=='/'){
          counter = counter + 1;
          continue;
      }
      else{

          if(counter==2)
              collegeName = collegeName + c;
          else if(counter == 3)
              year = year+c;
          else if(counter == 1)
              query_ID_LOLWA = query_ID_LOLWA + c;
          else

      }

  }
  console.log(collegeName);

  const query_final = query_ID_LOLWA;

  var helper = algoliasearchHelper(algoliasearch("****", "****"), 'books', {
    facets: ['collegeName', 'year','priority']});


  helper.on('result', function(data,query_ID_LOLWA){


        data.getFacetValues('priority',{sortBy: ['count:desc']});

        console.log(data.hits);

        var path_query = "/queries_answers/"+query_final;

        path_query = path_query.toString();
        console.log(path_query);
        if(data.hits.length==0){
            console.log("No results");
            database.ref(path_query).push(-1);
        }

        else if(data.hits.length>1){

            var ID = 1;
            var counter = -1;
            var length = data.hits.length-1;
            for(var h in data.hits){
                counter = counter + 1;
                if( (counter%5 == 0) && (counter != 0)){
                    ID = ID + 1;
                }

    helper.addFacetRefinement('year',year);

    helper.setQuery(query);



    helper.search();

没有比更多的详细信息，但没有成功，我们可以给您的唯一建议是按照常规步骤部署基于时间的 Azure 函数。

最简单的方法是使用 Azure Portal :

• Login to your Microsoft Azure account
• Create a Function App to host your function
• Add a Timer-triggered Function
• Select the TimerTrigger-Javascript template to get started

此时，您将拥有一个每分钟运行一次的函数。您可以检查日志以确认其正常工作。您现在想要配置其频率:

• Update the function's Timer Schedule (in the Integrate tab) to set how frequently the function should run
• Finally, replace the template's code with your own.

您可以找到detailed tutorial here 并解释如何实现每个步骤。
