Apollo GraphQL 标头在 iOS Swift 中总是失败

【中文标题】Apollo GraphQL 标头在 iOS Swift 中总是失败

【英文标题】：Apollo GraphQL header always gives failure in iOS Swift

【发布时间】：2021-07-22 21:09:11

【问题描述】：

我在我的 swift 项目中第一次使用 Apollo GraphQL 客户端。遵循他们文档中提到的所有步骤，并在谷歌上搜索我的问题，但没有运气。我通过在我的请求 URL 中传递一个标头发出了一个查询请求，但它总是给我一个错误消息，例如 failure(Apollo.LegacyParsingInterceptor.LegacyParsingError.couldNotParseToLegacyJSON(data: 1839 bytes))。我已经提到了link 的答案，但这对我不起作用。任何帮助将不胜感激。

我尝试了@ChamathJeevan 给出的相同代码语法，但它对我不起作用，我不知道为什么。
