小编Dik*_*mar的帖子

所以，我是 Android 新手，正在尝试运行我的第一个应用程序。创建一个空的活动项目并尝试使用模拟器运行它。我收到以下错误：

23:20 模拟器：模拟器：警告：EmulatorService.cpp:448：找不到 certfile：C:\Users\myUser\.android\emulator-grpc.cer 安全性将被禁用。

23:20 模拟器：在 127.0.0.1:8554 启动 GRPC 服务器

我尝试从 SDK 工具安装最新的 SDK，然后重新启动系统。还是不好。有人可以帮忙吗？

Android Studio 详细信息：Android Studio 3.6.1 Build #AI-192.7142.36.36.6241897，构建于 2020 年 2 月 27 日运行时版本：1.8.0_212-release-1586-b04 amd64 VM：OpenJDK 64 位服务器 VM，由 JetBrains sro Windows 提供10 10.0 GC：ParNew、ConcurrentMarkSweep 内存：1246M 核心：4 注册表：ide.new.welcome.screen.force=true 非捆绑插件：

对于背景，我正在遵循此处的教程：https://www.youtube.com/watch?v =HuN94qNwQmM 。

由于代码太长，我将其放入 git https://github.com/dikeshkumar135/CommandERGQL

现在，谈到问题，当我向这个机构提出请求时

    query{
     platform{
       id,
       name,
       commands{
         howTo
       }
     }
    }

我正在获取命令值为 null 的平台数据并出现以下错误：

{
  "message": "There was no argument with the name `platform` found on the field `commands`.",
  "locations": [
    {
      "line": 5,
      "column": 5
    }
  ],
  "path": [
    "platform",
    1,
    "commands"
  ],
  "extensions": {
    "fieldName": "commands",
    "argumentName": "platform"
  }

如果我删除类型，它工作正常，但如果我添加类型，那么获取相关对象时就会出现问题。

我是Laravel和PHP的新手.我正在使用POST方法来获取用户请求,并且我在verifyCSRFToken.php第68行中获取了TokenMismatchException.检查了server.php中的日志,发现以下内容.
