you should remove space from url and define scheme http or https
您应该从 url 中删除空间并定义方案 http 或 https
回答by Shubham
If you are Using localhost then pass url like this- http://localhost:8080/api/notesdefining scheme is important (http/https) do not use space also.
如果您使用 localhost，则像这样传递 url - http://localhost:8080/api/notes定义方案很重要（http/https）也不要使用空间。
