显示在Retrofit OnFailure 情况下收到的响应消息

Question

当来自 api 调用的数据 isSuccess 为 false 时，我尝试打印响应消息。但是，作为响应，我得到 isSuccess= false 但当我尝试打印消息时，它说数据为空。请帮我解决这个问题。

这是我调用 api 并观察 partsDetailData 的类。它进入 else 循环而不是进入 false 循环，尽管我得到的 isSuccess 为 false。邮递员结果显示 200。

期望：显示“部件 - 5272018 被取代为新部件号 - 6164702”作为 Toast，在 isSuccess=false 的情况下调用 partsDetailApi 时收到响应。

调试时，这里数据为空。

好的各位，我已经解决了这个问题。我收到的响应是一个字符串，因此它给了我 IllegalStateException，json 未成功解析。

{"isSuccess":false,"message":"部件 - 5272018 被取代为新部件号 - 6164702","response":"Error"}
