Ejabberd Oauth：访问被拒绝

【中文标题】Ejabberd Oauth：访问被拒绝

【英文标题】：Ejabberd Oauth: Access denied

【发布时间】：2019-09-22 10:46:30

【问题描述】：

我安装并配置了一个 Ejabberd XMPP 服务器。我测试了从移动应用程序连接到服务器并交换消息。现在我想启用 OAuth（需要将 OAuth 令牌生成集成到我自己的 Node.js REST API 中：登录我的 REST API = 登录我的 DB + Ejabberd OAuth 令牌生成）。我想通过在我的 REST API 登录中生成令牌并在我的 android/ios 应用程序中使用此令牌来防止执行 2 次登录调用（我的 REST API + Ejabberd）。

当我打开这个网址时：

http://my-server:5280/oauth/authorization_token?response_type=token&client_id=Client1&redirect_uri=http://my-server:3000/ejabberd&scope=get_roster+sasl_auth

我得到一个登录表单，在填写了有效凭据后，我被重定向到了这个网址：

http://my-server:5280/oauth/authorization_token

回复为空：ERR_EMPTY_RESPONSE

For reference, here is my configuration file:

【问题讨论】：

for user(jid) 在登录表单中，您是否将 jid ie 与主机名放在一起。管理员@主机名。由于使用您的配置，我尝试过并且得到了 oauth 令牌。

能否请您发送您尝试过的配置文件和您使用的网址

localhost:5443/oauth/… 我在工作时恢复了配置。上面的链接是我在 5443 端口上的配置。

@IrrupTor 我在日志中发现了这一点：[error] CRASH REPORT Process with 0 个邻居崩溃，原因是：调用未定义的函数 ejabberd_oauth:verify_resowner_scope(user,>,>, [>,>], password,>) [错误] 主管 ejabberd_http_sup 有孩子undefined 开始于 ejabberd_http,start_link,undefined 在 退出，原因是调用未定义函数 ejabberd_oauth:verify_resowner_scope(user,>,>, [>,>], password,>) 在上下文 child_terminated

@IrrupTor 我安装了 19.02 版，看起来不错。非常感谢。

【参考方案1】：

请检查您是否在配置 yml 中添加了以下配置。

commands_admin_access:
  - allow:
    - user: "admin@localhost"  # your user name.
commands:
  - add_commands: [user, admin, open]

oauth_access:
  - allow:
    - user:
      - "admin@localhost"  # add your user name

oauth_expire: 86400

请点击此处的链接： https://docs.ejabberd.im/developer/ejabberd-api/simple-configuration/

您可能错过了一些配置，因为我也遇到了类似的问题，但发现我错过了上述配置的某些部分。

【讨论】：

仍然遇到同样的问题，我确定我没有正确配置 ejabberd。我将更新我的问题以包含配置文件
