1) GET through JIRA rest api not working. 2)Unable to create query through Jquery Ajax.

[Vishal Dhawan]

I have 2 questions, and I amstuck on them for days.

1)

2-3 days back I was able to easily fetch(GET) issues through JIRA REST API using both POSTMAN and JS.

But recently I am unable to GET the issues. DELETE is working, even it shows error when I am fetching the wrong issue. But the page just keeps loading when fetching the correct issue.

2)

Please tell me how to create issue through JS, I have tried everything I can but can't make it to work. POSTMAN does it easily, but JS gives 'PREFLIGHT ERROR 403()'. 

URL, Username/Password everything is right.

<script>
 $(document).ready(function(){
 $("#sendButton").text("Create a new query.");


 $("#sendButton").click(function(){
 $.ajax({
 async:true,
 crossDomain: true,
 crossOrigin: true,
 method:"POST",
 url:"http://MY_URL/rest/api/2/issue",
 headers:{
 "Access-Control-Allow-Origin":"*",
 "Authorization":"Basic USERNAME:PASSWORD(with 64 bit encoding)",
 "Content-Type":"application/json"
 },
 processData: false,
 data: JSON.stringify({
 "fields":
 {
 "project": {
 "key": "CONV",
 "name": "Conval Application"
 },
 
 "summary": "TEST11.0 (PLEASE IGNORE THIS)",
 
 "issuetype":{
 "name":"Test"
 },
 
 "priority":{
 "name": "Trivial (4)"
 }
 }
 }),
 success:function(data)
 {
 $("#readStuff").text(data);
 console.log(data);
 },
 error:function(data)
 {
 $("#readStuff").text(data.status);
 console.log(data);
 }
 });
 });

 });
</script>
