Yes. You need to stringify the JSON data orlse 400 bad request error occurs as it cannot identify the data.
400 Bad Request
Bad Request. Your browser sent a request that this server could not understand.
Plus you need to add content type and datatype as well. If not you will encounter 415 error which says Unsupported Media Type.
415 Unsupported Media Type
Try this.
var newData = {
"subject:title":"Test Name",
"subject:description":"Creating test subject to check POST method API",
"sub:tags": ["facebook:work", "facebook:likes"],
"sampleSize" : 10,
"values": ["science", "machine-learning"]
};
var dataJson = JSON.stringify(newData);
$.ajax({
type: 'POST',
url: "http://localhost:8080/project/server/rest/subjects",
data: dataJson,
error: function(e) {
console.log(e);
},
dataType: "json",
contentType: "application/json"
});
With this way you can modify the data you need with ease. It wont confuse you as it is defined outside the ajax block.
