我有一个问题，我需要从CheckWX.com API解析多个对象类型的响应。 （请参见https://api.checkwx.com/）。目前，我的代码中包含ScalarsConverterFactory和GSONConverterFactory。我的Gson转换器工作正常，没有错误。但是，当我收到错误消息时，解析似乎失败并且调用了onFailure。我需要报告所有成功的站点以及失败的站点。如何在翻新中处理此问题？
这是单个站点请求错误的响应：
{
"results":1,
"data":[
"KNZL Invalid Station ICAO"
]
}
这是对站请求的响应，没有错误：

这是我的改装客户的代码：
retrofit = new Retrofit.Builder().baseUrl(baseUrl)
.client(getHttpClient())
.addConverterFactory(ScalarsConverterFactory.create())
.addConverterFactory(GsonConverterFactory.create(gson))
.build();
正如我所说，我需要知道的是如何正确解析响应中的错误字符串：为澄清起见，这里是错误：
CheckWXApi: onFailure: java.lang.IllegalStateException: Expected
BEGIN_OBJECT but was STRING at line 1 column 755 path $.data[1],
java.lang.IllegalStateException: Expected BEGIN_OBJECT but was
STRING at line 1 column 755 path $.data[1]
2018-11-04 11:55:52.376 25533-25533/us.sensornet.aviationweatherv2
D/CheckWXApiProxy: onMetarReportFailure: called:
java.lang.IllegalStateException: Expected BEGIN_OBJECT but was
STRING at line 1 column 755 path $.data[1]
Caused BY: java.lang.IllegalStateException: Expected BEGIN_OBJECT
but was STRING at line 1 column 755 path $.data[1].
用于具有一个成功工作站和一个错误的查询。如果查看提供的响应，则会看到数据数组中返回的最后一个或两个对象是字符串错误消息，而不是metar weather对象。我的问题是正确处理这些字符串。仅仅添加ScalarConverterFactory并不能解决这个问题。
