I am building a CRUD application using embers as client and struts2 as server. The post request to create a record from ember looks like,
Accept: application/json, text/javascript, /; q=0.01 Accept-Encoding: gzip, deflate, br Accept-Language: en-GB,en-US;q=0.9,en;q=0.8 Connection: keep-alive Content-Length: 54 Content-Type: application/json; charset=UTF-8 Host: localhost:8080 Origin: http://localhost:4200 Referer: http://localhost:4200/create Sec-Fetch-Mode: cors Sec-Fetch-Site: same-site User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.88 Safari/537.36 {product: "{"name":"iamironman","price":3000}"} product: "{"name":"iamironman","price":3000}"
