Apollo GraphQL标头在iOS Swift中总是会失败 [英] Apollo GraphQL header always gives failure in iOS Swift

问题描述

在我的swift项目中，我第一次使用Apollo GraphQL客户端.遵循他们文档中提到的所有步骤，并在Google上搜索了我的问题，但是没有运气.我通过在请求URL中传递标头来发出查询请求，但它总是使我失败，并显示错误消息，例如 failure(Apollo.LegacyParsingInterceptor.LegacyParsingError.couldNotParseToLegacyJSON(data:1839 bytes)).我已提及链接的答案，但这不适用于我.任何帮助将不胜感激.

I am working with the Apollo GraphQL client for the first time in my swift project. Followed all the steps mentioned in their document and searched over google for my issue but had no luck. I have made a query request by passing a header in my request URL but it always gives me a failure with error msg like failure(Apollo.LegacyParsingInterceptor.LegacyParsingError.couldNotParseToLegacyJSON(data: 1839 bytes)). I have referred answer of link but this is not worked for me. Any Help will be most appreciated.
