编程并不是一个机械性的工作，而是需要有思考，有创新的工作，语法是固定的，但解决问题的思路则是依靠人的思维，这就需要我们坚持学习和更新自己的知识。今天golang学习网就整理分享《OpenAPI Golang 客户端在处理日期上存在问题？》，文章讲解的知识点主要包括，如果你对Golang方面的知识点感兴趣，就不要错过golang学习网，在这可以对大家的知识积累有所帮助，助力开发能力的提升。

问题内容

我正在开发一个提供交易列表的 api。我用 java/kotlin spring 编写它，但更喜欢使用 golang 作为 cli，所以我为其生成一个 golang 客户端。该 api 在 swagger ui 中运行良好。

kotlin api：

@getmapping
fun listtransactions() : responseentity<list<transaction>> {
    val transactions = arraylist<transaction>()
    transactionrepository.findall().mapto(transactions) { fromentity(it) }
    return responseentity.ok(transactions)
}

kotlin 对象：

data class transaction(
        val id: long,
        val transactiondate: date, // java sql date
        val posteddate: date?, // java sql date
        val amount: bigdecimal,
        val category: category,
        val merchant: merchant,
        val merchantdescription: string?
)

生成的架构：

                        "$ref": "#/components/schemas/category"
                    },
                    "merchant": {
                        "$ref": "#/components/schemas/merchant"
                    },
                    "merchantdescription": {
                        "type": "string"
                    }
                }
            }
        }
    }
}

golang 客户端对象：

type transaction struct {
   id *int64 `json:"id,omitempty"`
   transactiondate *time.time `json:"transactiondate,omitempty"`
   posteddate *time.time `json:"posteddate,omitempty"`
   amount *float32 `json:"amount,omitempty"`
   category *category `json:"category,omitempty"`
   merchant *merchant `json:"merchant,omitempty"`
   merchantdescription *string `json:"merchantdescription,omitempty"`
}

所有这些看起来都足够正确。但是，当我使用 openapi 客户端时，反序列化似乎无法正常工作：

Error when calling `TransactionRouterApi.ListTransactions``: parsing time "\"2022-10-28\"" as "\"2006-01-02T15:04:05Z07:00\"": cannot parse "\"" as "T"

我是否做错了什么导致反序列化失败？或者这是一个客户端错误（似乎很可疑，但谁知道呢）。

我查看了我使用的生成参数和端点上可用的架构，它们看起来都是正确的。
