[keroles hakem]

working on building desktop app using angular 4 and electron and try to get authentication token for jira but i am getting back  status code:  500, any help to get around this issue. i believe it is cors issue :

here is request headers:

• :authority:somecompany.atlassian.net
• :method:POST
• :path:/rest/auth/1/session
• :scheme:https
• accept:application/json, text/plain, */*
• accept-encoding:gzip, deflate
• accept-language:en-US
• content-length:51
• content-type:application/json
• origin:file://

return message from server: 

{"message":"Expected authority at index 7: file://","status-code":500,"stack-trace":
"java.lang.IllegalArgumentException: Expected authority at index 7: file:// ...etc

 this.http.post('https://somecompany.atlassian.net/rest/auth/1/session' , body)
.subscribe(d => { 
console.log(d); 
this.router.navigate(['/home']); 
}, 
error => { 
console.log('errororororororor'); 
console.log(error); 
}); 
}

You need to add headers on a proxy service using reverse proxy like nginx. I use docker to test with a reverse proxy service to add cross origin headers. Otherwise Jira doesn't allow it. At least not in Jira Cloud REST API. If you use Jira Server I believe you can whitelist apps through config/settings. The issue is actually browser side and you can use chrome plugin to disable the check but that's not advisable.
