Full authentication is required to access this resource

nginx出现这个问题：
{“error”:“unauthorized”,“error_description”:“Full authentication is required to access this resource”}

Nginx.conf
1、这个地址不能出现双//
http://XXXXX:8310//api;
2、最后不能出现/
http://XXXXX:8310/api/;

正确配置：
location /api {
proxy_pass http://XXXXX:8310/api;
}
