GeoServer/OpenLayers WFS: "Could not determine geoserver request from http request..."

Question

I'm using Openlayers + GeoServer to draw a new point and save it. But there are some errors.

Code as follows:

function onSaveNewPoint() {

      for(var i = 0 ; i < drawedFeaturePointArray.length ; i++){

      var geometry = drawedFeaturePointArray[i].getGeometry().clone();
      geometry.applyTransform(function(flatCoordinates, flatCoordinates2, stride) {
        for (var j = 0; j < flatCoordinates.length; j += stride) {
          var y = flatCoordinates[j];
          var x = flatCoordinates[j + 1];
          flatCoordinates[j] = x;
          flatCoordinates[j + 1] = y;
        }
      });
      var newFeature = new ol.Feature();
      newFeature.setId('cities.2406.new.' + newPointId);
      newFeature.setGeometryName('the_geom');
      newFeature.set('CITY_NAME', newFeature.getId());
      newFeature.set('GMI_ADMIN', newFeature.getId());
      newFeature.set('ADMIN_NAME', 0);
      newFeature.set('FIPS_CNTRY', '');
      newFeature.set('CNTRY_NAME', '');
      newFeature.set('STATUS', 'test');
      newFeature.set('POP_RANK', 0);
      newFeature.set('POP_CLASS', '');
      newFeature.set('PORT_ID', 0);
      newFeature.set('LABEL_FLAG', 0);
      newFeature.setGeometry(new ol.geom.Point([geometry.getCoordinates()]));

      addWfsPoint([newFeature]);
      newPointId = newPointId + 1;
      setTimeout(function(){
        console.log('next Feature');
      },3000);
    }      
  }

function addWfsPoint(features) {
      var WFSTSerializer = new ol.format.WFS();
      var featObject = WFSTSerializer.writeTransaction(features,
        null, null, {
          featureType: 'WorldCities',
          featureNS: 'http://geoserver.org/WorldCities',
          srsName: 'EPSG:4326'
        });
      var serializer = new XMLSerializer();
      var featString = serializer.serializeToString(featObject).replace('undefined','');;

      var request = new XMLHttpRequest();
      request.open('POST', 'http://localhost:8080/geoserver/wfs?service=wfs');
      request.setRequestHeader('Content-Type', 'text/xml');
      request.send(featString);
    }

Errors as follows:

I've searched online, but still don't know how to resolve this problem. I hope someone here can help me out.

Answer 1

The request is lacking all namespaces besides the WFS one, you'll need to add namespace and prefix for the WorldCities feature and attributes, as well as the GML namespaces for the GML elements in it. Use a GeoServer WFS 1.1 response as guidance.
