GraphQL/APOLLO - 无法在“查询”类型上查询字段“field_name”

Question

我正在尝试在最新的 apollo/server 4.9 和 graphqlClient - 3.7 中进行这样的查询，如下所示：

const USER_DATA = gql`
query getUserData($subdomain: String!) {
getUserData(subdomain: $subdomain) {
  _id
  full_name
  email
  valid_complex_password
  projects {
    _id
    image_url
    title
    description
    street_address
    city
    province
    country
  }
 }
}

但继续得到这个：

{
"errors": [
    {
        "message": "Cannot query field \"getUserData\" on type \"Query\".",
        "locations": [
            {
                "line": 2,
                "column": 3
            }
        ],
        "extensions": {
            "code": "GRAPHQL_VALIDATION_FAILED",
            "stacktrace": [
                "GraphQLError: Cannot query field \"getUserData\" on type \"Query\".",
                ......
            ]
        }
    }
]

}

同样的查询过去可以在旧版本的 apollo 服务器/客户端和 graphql 上正常工作。升级后，它开始崩溃，而无需对架构等进行任何更改。

查询方式有什么需要更改的或者我遗漏了什么吗？

Answer 1

简短的回答是，您已经在 Apollo-server 中跨 2 个版本的重大更改进行了迁移。您需要迁移您的项目才能使其在 apollo-server v4.x 世界中工作。

如果您不使用 Express 来提供任何其他内容，我建议仅使用 apollo-server 并放弃 Express。 v4 中使用 Apollo 和 Express 的模型有很大不同。
