EMQX中如何访问RestAPI

1、查看restapi端口

# netstat -tnulp|grep 19656
tcp        0      0 0.0.0.0:6369                0.0.0.0:*                   LISTEN      19656/beam.smp     
tcp        0      0 0.0.0.0:18083               0.0.0.0:*                   LISTEN      19656/beam.smp     
tcp        0      0 127.0.0.1:11883             0.0.0.0:*                   LISTEN      19656/beam.smp     
tcp        0      0 0.0.0.0:8883                0.0.0.0:*                   LISTEN      19656/beam.smp     
tcp        0      0 0.0.0.0:9080                0.0.0.0:*                   LISTEN      19656/beam.smp     
tcp        0      0 0.0.0.0:5369                0.0.0.0:*                   LISTEN      19656/beam.smp     
tcp        0      0 0.0.0.0:1883                0.0.0.0:*                   LISTEN      19656/beam.smp 

2、创建访问RestAPI的认证应用ID

[1/3] # ./emqx_ctl mgmt  insert <AppId> <Name>
# ./emqx_ctl mgmt insert b28477fa9f9798 Client@Yours
AppSecret: Mjg3ODQxNjgyNTc2Mjg1NDUzNzA3ODczNDM3MDc1Mzc0MDI
[2/3] # ./emqx_ctl mgmt list
app_id: b28477fa9f9798, secret: Mjg3ODQxNjgyNTc2Mjg1NDUzNzA3ODczNDM3MDc1Mzc0MDI, name: Client@Yours, desc: Application user, status: true, expired: undefined
[3/3] curl -v --basic -u <appid>:<appsecret> -k http://<eqmx_node_host>:8080/api/v3/brokers
=> <appid>:<appsecret>，可以通过CLI或者Dashboard进行创建

3、通过认证应用ID和秘钥进行访问

# curl -v --basic -u b28477fa9f9798:Mjg3ODQxNjgyNTc2Mjg1NDUzNzA3ODczNDM3MDc1Mzc0MDI -k http://192.168.1.148:9080/api/v3/brokers/
