volttron - 应用“RPC.allow”时如何调用函数？

问题描述

 在volttron/platform/store.py文件中，它包含：

@ RPC.export
@ RPC.allow ('edit_config_store')
def manage_store (self, identity, config_name, raw_contents, config_type = "raw"):
    contents = process_raw_config (raw_contents, config_type)
    self._add_config_to_store (identity, config_name, raw_contents, contents, config_type,
                                  trigger_callback = True)

为了从外部调用这个函数，我编写了如下代码。

 self.vip.rpc.call (CONFIGURATION_STORE, "manage_store", 'platform.driver', config_name, raw_contents, 'json')

错误代码如下。

volttron.platform.jsonrpc.Error: method "manage_store" requires capabilities {'edit_config_store'}, but capability [] was provided for user pnp

auth 注册如下。

INDEX: 8
{
  "domain": null,
  "address": null,
  "mechanism": "CURVE",
  "credentials": "6vjPXC8ctO8oWkeMXAOe5FsAM9vZD_sg0vkLrstnVFs",
  "groups": [],
  "roles": [],
  "capabilities": {
    "edit_config_store": {
      "identity": "pnp.b"
    }
  },
  "comments": "Automatically added on agent install",
  "user_id": "pnp.b",
  "enabled": true
}

如何修复能力？

解决方案

非常感谢您的回答。

参考您的回答，我正在纠正身份验证的能力。

    INDEX: 8
{
  "domain": null,
  "address": null,
  "mechanism": "CURVE",
  "credentials": "TG3z7cEa1FnMp_642srvNLyd6HsxTq18xMOg20FFWjE",
  "groups": [],
  "roles": [],
  "capabilities": {
    "edit_config_store": {
      "identity": "/pnp.b|platform.driver/"
    }
  },
  "comments": "Automatically added on agent install",
  "user_id": "pnp.b",
  "enabled": true
}

但是，它仍然显示代理未授权，如下面的日志所示。

是不是我改正的时候搞错了？您对此有何评论？

注意：我使用 volttron 7.0rc 分支。
