对Wiki.js的Graphql的响应是“禁止的”

Question

我使用Wiki.js作为停靠容器，并且知道它确实支持Graphql响应API请求(例如:获取wiki页面内容)。当我试图查询一个页面的标题时，我会收到一条响应消息，称为“禁止的”。

请求：

query{
  pages {
    single(id: 2 ){
      title
    }
  }
}

响应：

{
  "errors": [
    {
      "message": "Forbidden",
      "locations": [
        {
          "line": 3,
          "column": 5
        }
      ],
      "path": [
        "pages",
        "single"
      ],
      "extensions": {
        "code": "INTERNAL_SERVER_ERROR",
        "exception": {
          "stacktrace": [
            "Error: Forbidden",
            "    at field.resolve (/wiki/server/graph/directives/auth.js:47:17)",
            "    at field.resolve (/wiki/node_modules/graphql-extensions/dist/index.js:133:26)",
            "    at resolveFieldValueOrError (/wiki/node_modules/graphql/execution/execute.js:467:18)",
            "    at resolveField (/wiki/node_modules/graphql/execution/execute.js:434:16)",
            "    at executeFields (/wiki/node_modules/graphql/execution/execute.js:275:18)",
            "    at collectAndExecuteSubfields (/wiki/node_modules/graphql/execution/execute.js:713:10)",
            "    at completeObjectValue (/wiki/node_modules/graphql/execution/execute.js:703:10)",
            "    at completeValue (/wiki/node_modules/graphql/execution/execute.js:591:12)",
            "    at /wiki/node_modules/graphql/execution/execute.js:492:16",
            "    at process._tickCallback (internal/process/next_tick.js:68:7)"
          ]
        }
      }
    }
  ],
  "data": {
    "pages": {
      "single": null
    }
  }
} 

有人能让我知道我做错了什么来通过wiki.js的Graphql获得页面的标题吗？

谢谢你的帮助。

假设我们正在从Graphql游乐场进行查询

我花了一些时间来理解它，但这里是如何启动graphql查询，这需要授权用户的权限。

您需要确保请求来自授权用户的服务器，为此触发登录请求，并为该用户获取令牌(jwt)。

mutation { 
    authentication {
    login(
      username: "username@test.com",
      password: "yourpassword",
      strategy: "local"
    ) {
      jwt
    }
  }
}

然后在Headers中添加从登录请求中收到的令牌，如

{
  "Authorization": "Bearer longStringOfYourJwtToken"
}

希望这能帮助其他像我这样的记者理解Wiki.js和GraphQL。
