Retrofit2 OkHttp3響應正文空錯誤

我正在使用Retrofit 2來調用一個微服務，它返回一個200和一個PUT方法上的空響應主體。改造2但似乎不能夠處理這一點，並在「排隊」進入到onFailure處分支

任何人都知道是什麼原因造成的？由於請求已成功發送（請參見上文）。

這是相當奇怪之前添加該轉換器。您的電話是否會返回任何可能會嘗試進行反序列化的對象？通過電話我的意思是java界面 – Fred

你找到解決方案嗎？我面臨同樣的問題。看起來這是一些傑克遜版本發生。你正在使用哪個版本？ – Pawan

嗨，是的，你需要像這裏https://github.com/square/retrofit/issues/1554 – razvan

我創建了一個空的處理程序轉換器針對此問題：

public class NullOnEmptyConverterFactory extends Converter.Factory { 

    @Override 
    public Converter<ResponseBody, ?> responseBodyConverter(Type type, Annotation[] annotations, Retrofit retrofit) { 
     final Converter<ResponseBody, ?> delegate = retrofit.nextResponseBodyConverter(this, type, annotations); 
     return (Converter<ResponseBody, Object>) body -> { 
      if (body.contentLength() == 0) return null; 
      return delegate.convert(body); 
     }; 
    } 
}

你需要你的GSON轉換器

.addConverterFactory(new NullOnEmptyConverterFactory())
