showing 400 (Bad Request) in ajax

Question

I am using cordova and while doing json i am getting an error "Failed to load resource: the server responded with a status of 400 (Bad Request)".

But the same code when I run it on postman is getting the right answer.Please help me to solve this problem. The code is:

$.ajax({ url: url, type: "POST", async: false, ContentType: "application/json; charset=utf-8", data: jData, dataType: "json", success: function(response) { console.log(response) }, error: function(jqXHR, textStatus, errorThrown) { }, });

And a screenshot of the right answer on the postman is also given for your reference

"the server responded with a status of 400 (Bad Request)" -> Check the request and what the server expects — Andreas

then something is wrong with your jData json or api might expect different contenttype — Pramod S. Nikam

but when I run the same url in the postman ,the right answer is getting — Durga

you need to stringify the JSON data was sending

$.ajax({ type: 'POST', url: url, async: false, data: JSON.stringify(jData), dataType: "json", contentType: "application/json; charset=utf-8", success: function(response) { console.log(response) }, error: function(jqXHR, textStatus, errorThrown) { } });

after stringifying the json data, it shows the following errors:

Durga Over a year ago

1.Failed to load resource: the server responded with a status of 405 (Method Not Allowed )

2.Failed to load url :Response for preflight has invalid HTTP status code 405

Maybe something missing in your server configuration tries to configure Access-Control-Allow-Origin and Access-Control-Allow-Origin.[may this help][1].[may this help][2] [1]: stackoverflow.com/questions/36002979/… [2]: stackoverflow.com/questions/36258959/…

Try removing the open and closing brackets around your jData

var jData = {};

Not

var jData = [{}];
