GraphQL突变问题

Question

我是GraphQL的新手。我正在学习GraphQL。

我的输入如下所示

mutation {
  createEvent:{eventInput: {title: "A Test", description:"Does this work?", price:9.99, date:"2018-12-06T09:26:30.645Z"}
    }
}

我遇到如下错误

{
  "errors": [
    {
      "message": "Syntax Error: Expected Name, found {",
      "locations": [
        {
          "line": 2,
          "column": 15
        }
      ]
    }
  ]
}

好吧，我相信您的createEvent突变应该返回一个对象类型。对于对象类型，您必须为此Mutation指定返回类型的至少一个字段。

应该是：

mutation {
  createEvent(eventInput: {
        title: "A Test" 
        description:"Does this work?"
        price:9.99
        date:"2018-12-06T09:26:30.645Z"
    }){
        someFieldInTheReturnType
    }
}
