graphql - 对 Wiki.js 的 Graphql API 的响应是 "Forbidden"

Question

我正在使用 Wiki.js作为 docker 容器并开始知道它确实支持 Graphql 来响应 API 请求(例如:获取 wiki 页面内容)。当我尝试向它查询页面标题时，我收到一条响应消息“Forbidden”。

要求:

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
    }
  }
} 

有人可以让我知道我在通过 wiki.js 的 Graphql API 获取页面标题时做错了什么吗？

感谢您的帮助。

假设我们从 Graphql Playground 触发查询

我花了一些时间来理解它，但这里是如何触发需要授权用户许可的 graphql 查询。

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 token (jwt)

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

然后在 HTTP header 中添加您从登录请求中收到的 token

{
  "Authorization": "Bearer longStringOfYourJwtToken"
}

希望这能帮助像我这样的新手理解 Wiki.js 和 GraphQL
