The server refused this petition due to the fact that the petition entity is successful a format not supported by the requested assets for the requested technique ().
Tomcat log:"Station /ui/webapp/conf/broad HTTP/1.1" 415 1051
What is the correct format of the cURL bid?
This is my Java broadside PUT codification (I person examined Acquire and DELETE and they activity):
@RequestMapping(method = RequestMethod.PUT)public Configuration updateConfiguration(HttpServletResponse response, @RequestBody Configuration configuration) { //consider @Valid tag configuration.setName("PUT worked"); //todo If error occurs response.sendError(HttpServletResponse.SC_NOT_FOUND); return configuration;}You demand to fit your contented-kind to exertion/json. However -d (oregon --data) sends the Contented-Kind application/x-www-form-urlencoded by default, which is not accepted connected Outpouring's broadside.
Wanting astatine the curl male leaf, I deliberation you tin usage -H (oregon --header):
-H "Content-Type: application/json"Afloat illustration:
curl --header "Content-Type: application/json" \ --request POST \ --data '{"username":"xyz","password":"xyz"}' \ http://localhost:3000/api/login(-H is abbreviated for --header, -d for --data)
Line that -request POST is elective if you usage -d, arsenic the -d emblem implies a Station petition.
