node.js - Update elasticsearch doc via node js api -

i trying update doc particular id via node.js api in elasticsearch. new node.js, can't figure out why update fails. here relevant snipet webapp.js file:

app.post('/api/resources/:id', function(req, res) {  var resource = req.body; var param = { index: 'test', type: 'tes', _id : req.params.id, doc:resource };   console.log("modifying resource:", req.params.id, resource);   client.update(param, function (error, response) { //   client.get({ index: 'test', type: 'tes', id: req.params.id }, function(err, resource) {       res.send(response);     }); //  }); }); 

i testing via curl command line using command :

curl -v \   --data '{"name":"xxx"}' \   http://localhost:3000/api/resources/av2ebdzxwll5fjupdx0r 

here response receive command line:

*   trying ::1... * tcp_nodelay set * connected localhost (::1) port 3000 (#0) > post /api/resources/av2ebdzxwll5fjupdx0r http/1.1 > host: localhost:3000 > user-agent: curl/7.51.0 > accept: */* > content-length: 81 > content-type: application/x-www-form-urlencoded >  * upload sent off: 81 out of 81 bytes < http/1.1 200 ok < x-powered-by: express < date: fri, 28 jul 2017 16:40:53 gmt < connection: keep-alive < content-length: 0 <  * curl_http_done: called premature == 0 * connection #0 host localhost left intact 

the document not getting updated. can me figure out doing wrong here.

your param hash not correct, _id should id , doc should body. thing partial update, need enclose partial fields in doc structure:

var resource = {doc: req.body}; var param = { index: 'test', type: 'tes', id: req.params.id, body: resource }                                            ^                   ^                                            |                   |                                           change these 2 params
