Question

我使用retrofit2 + gson。我的问题是关于什么时候服务器有数据，它发送给我json像：

{
 "next":false,
 "total":4,
 "start":0,
 "rows":[
  {
     "calls":29,
     "new_calls":29,
     "new_quality_calls":10,
     "item":"MzY4NzA3NDA0Mw",
     "sessions":3,
     "calls_per":966.66666666666663
  },
  {
     "calls":15,
     "new_calls":15,
     "new_quality_calls":5,
     "item":"test312312312",
     "sessions":2,
     "calls_per":750
  },
  {
     "calls":0,
     "new_calls":0,
     "new_quality_calls":0,
     "item":"test",
     "sessions":4,
     "calls_per":0
  },
  {
     "calls":0,
     "new_calls":0,
     "new_quality_calls":0,
     "item":"test2",
     "sessions":2,
     "calls_per":0
  }
],
"summary":{
  "sessions":11,
  "calls":44,
  "new_calls":44,
  "new_quality_calls":15,
  "calls_per":400
}
}

但是当没有数据时，它会发送给我：

{"next":false,"total":0,"start":0,"rows":[],"summary":[]}

问题是summary是一个对象或数组是某种情况。我使用这个网站制作gson calsses http://www.jsonschema2pojo.org/

当我得到数据时它没问题，但是当没有数据时我得到了一个错误：

Expected BEGIN_OBJECT but was BEGIN_ARRAY at line 1 column 56 path

如何在没有手动数据解析的情况下通过retroft2 (.addConverterFactory(GsonConverterFactory.create()))自动解决？

Answer 1

添加你自己的转换器，它将解析AST（readTree），检查$.summary类型，修复它，然后将这个固定的AST提供给TypeAdapter。

gson解析对象时有数据和数组时没有数据
