在我的项目开发过程中，我正在使用带有 graphql 的颤振，为了测试目的，在操场上尝试了突变并通过了测试，但是在设备和模拟器上得到 5xx 的错误响应，我知道这是“服务器端”错误，但测试了相同的突变我们的网页，它也在工作。除了颤振，我正在使用以下软件包：

  • 等价的：^1.2.5
  • gql: ^0.12.4
  • 图ql：^4.0.0
  • graphql_flutter：^4.0.1
  • json_annotation: ^3.1.1
  • 元：^1.3.0
  • 阿尔忒弥斯：^6.18.4
  • build_runner：^1.11.1
  • json_serializable: ^3.5.1

到目前为止，在这个项目中，我使用以下文件语法成功运行了近 10 个突变：

  • 我的项目/
    • 图ql/
      • 查询/
        • register.graphql -> 运行良好
        • createOffer.graphql -> 出现 500 错误

为了检查graphql验证是否有效，我在开始时间/结束时间的日期时间上犯了错误并得到这个：

这意味着我发送的所有字段都是正确的，我想。也许请求的字段类型正在接受我的有效输入类型，但在工作/解析它们时导致错误，我不知道，我为此苦苦挣扎了将近一周，你可以看到两个硬代码（颤振/游乐场）是相同的. 我的文本字段和其他输入已准备好，但我首先无法运行硬编码：/ 顺便说一句，这不是过期的令牌，因为我得到了未经授权的操作错误。

最后我们可以解决这个问题。解析数据来自我这边时，后端出现问题。这是数据流：

  • 用户输入数据
  • 变异前，flutter解析数据和graphql_flutter变异
  • 然后，如果一切正常，后端（在我们的例子中是 php）会进行字段验证，如果没有，则将验证错误发送到客户端。
  • 毕竟，服务器开始在 db 上存储数据（这是关键点）

我的问题发生在最后阶段，不必要的模型属性被发送为空，我们通过阅读 laravel.log 中的日志来了解这一点，因此删除该字段并迁移数据库，最后从操场下载并使用“新”schema.graphql 解决了这个问题问题。我希望这对以后有帮助:)
