場景：有個項目需要用到refit請求第三方接口，這個接口的請求參數是需要大寫的，如果用了refit自帶的AliasAs參數或者用JsonProperty("A")都無法序列化參數字段大寫“A”，都會被首字母駝峰策略序列化成小寫“a”

[AliasAs("A")] public string Name { get; set; } var otherApi = RestService.For<IOtherApi>("https://api.example.com",new RefitSettings {ContentSerializer = new NewtonsoftJsonContentSerializer(new JsonSerializerSettings {ContractResolver = new CamelCasePropertyNamesContractResolver()})});

后面查google都找不到解決方法，后面看了這個問題有了些思路

https://github.com/reactiveui/refit/issues/1122

把CamelCasePropertyNamesContractResolver 改成CamelCaseNamingStrategy，參考兩種區別：https://stackoverflow.com/questions/57774336/camelcasenamingstrategy-vs-camelcasepropertynamescontractresolver

應該是由于CamelCasePropertyNamesContractResolver策略強制轉化首字母小寫，CamelCaseNamingStrategy默認的就是DefaultContractResolver + CamelCaseNamingStrategy，才可以正常達到以下效果：
1. 沒有標記JsonProperty的，默認小寫
2. 有標記JsonProperty的，嚴格按照JsonProperty配置的Name
注意：如果換成CamelCaseContractResolver，會使用JsonProperty的Name，但同時也會把他強制轉成小寫

改完后的代碼：

var otherApi = RestService.For<IOtherApi>("https://api.example.com",new RefitSettings {ContentSerializer = new NewtonsoftJsonContentSerializer(new JsonSerializerSettings {ContractResolver = new DefaultContractResolver(){NamingStrategy = new CamelCaseNamingStrategy()}})});
