Cygnus通知 - 不支持application/json内容类型

Question

当我向Cygnus发送通知时，我收到一条400响应，消息application/json content type not supported，但我在请求中设置了Content-Type和Accept标头。我已在下面发布了请求和回复。

$ curl http://localhost:5050/notify -v -s -S --header 'Accept: application/json' --header 'Content-Type: application/json' --header "Fiware-Service: qsg" --header "Fiware-ServicePath: /testsink" -d @- <<EOF

Answer 1

这是因为从cygnus 1.1.0开始只接受UTF-8字符集。为了解决这个问题，只需设置Content-Type头application/json; charset=utf-8

因此请求将成为：

$ curl http://localhost:5050/notify -v -s -S --header 'Accept: application/json' --header 'Content-Type: application/json; charset=utf-8' --header "Fiware-Service: qsg" --header "Fiware-ServicePath: /testsink" -d @- <<EOF
