Stackstorm 2.7 webhook“访问被拒绝：403”

Question

我已经成功地在stackstorm中创建了一个webhook，它可以在webhook列表中看到。你知道吗

 [centos@ip- ~]$ sudo st2 webhook list
 +------------+------------------+-------------+
 | url        | type             | description |
 +------------+------------------+-------------+
 | wfcreation | core.st2.webhook |             |
 +------------+------------------+-------------+
 [centos@ip- ~]$

我触发了webhook，使用stackstormapi键提供有效负载并设置正确的头。webhook被触发并返回状态码200。但是底层的stackstorm工作流失败，出现以下错误。你知道吗

{
  "traceback": "  File \"/opt/stackstorm/st2/lib/python2.7/site-packages/st2actions/container/base.py\", line 119, in _do_run

",
  "error": "AccessRefused: 403"
}   

官方的stakstorm文档没有任何关于解决此错误的参考资料。你知道吗

任何帮助将不胜感激，因为我现在在这方面受阻。你知道吗

Answer 1

最后我发现问题出在stackstorm主机上运行的mistral服务器服务。你知道吗

问题是，由于stackstorm期间的错误配置，mistral服务器服务无法连接到rabbitmq服务安装。但是误导性错误消息“accessrejected:403”没有指向rabbitmq连接问题。你知道吗

这是我在日志里找到的。你知道吗

mistral日志（/var/log/mistral/）中的错误消息：

2018-06-25 15:30:19.309 10767 ERROR oslo_service.service AccessRefused: (0,0): (403) ACCESS_REFUSED - Login was refused using authentication mechanism AMQPLAIN. For details see the broker logfile.

在挖掘rabbitmq日志时（/var/log/rabbitmq/）：

=ERROR REPORT==== 25-Jun-2018::16:34:23 ===
closing AMQP connection <0.5118.0> (127.0.0.1:41248 -> 127.0.0.1:5672):
{handshake_error,starting,0,
             {amqp_error,access_refused,
                         "AMQPLAIN login refused: user 'st2' - invalid credentials",
                         'connection.start_ok'}}

很明显，st2用户凭据在安装过程中配置错误，导致了整个问题。你知道吗

希望这对将来有帮助。你知道吗

另一个可能导致这种情况的原因是没有配置NGinx，在这种情况下，系统希望您使用本地端口。下面是一个可能对您有所帮助的示例：https://github.com/StackStorm/st2/tree/master/conf/st2.conf.sample，下面是nginx config。你知道吗
