关于Gson解析失败：Use JsonReader.setLenient(true) to accept malformed JSON at line 1 column 1 path $

找了半天，终于搞定了，不得不说，这是个坚强的bug,真的是个坚强的bug...

一把辛酸了，，啥也不说了，希望遇到一样坑的小伙伴 别放弃，你们还有我。。。。哈哈

解决办法：划重点。原来用的 GsonConverterFactory 解决一些接口返回值规范的一点问题都没有，偏偏有些接口真的不听话，成功返回个字符串"OK",失败,返回一大串Json异常信息，乖乖嘞。。。 下面这个方法这样写就可以啦

奉上LenientGsonConverterFactory.java类

    /**

     * decoding from JSON (when no charset is specified by a header) will use UTF-8.
     */
    public static LenientGsonConverterFactory create() {
        return create(new Gson());
    }

    /**

    }

    private final Gson gson;

    private LenientGsonConverterFactory(Gson gson) {
        if (gson == null) throw new NullPointerException("gson == null");
        this.gson = gson;
    }

            } finally {
                value.close();
            }
        }
    }

        private  final MediaType MEDIA_TYPE = MediaType.parse("application/json; charset=UTF-8");
        private  final Charset UTF_8 = Charset.forName("UTF-8");

        private final Gson gson;
        private final TypeAdapter adapter;

        LenientGsonRequestBodyConverter(Gson gson, TypeAdapter adapter) {
            this.gson = gson;
            this.adapter = adapter;
        }

        @Override

            Buffer buffer = new Buffer();
            Writer writer = new OutputStreamWriter(buffer.outputStream(), UTF_8);
            JsonWriter jsonWriter = gson.newJsonWriter(writer);
            jsonWriter.setLenient(true);
            adapter.write(jsonWriter, value);
            jsonWriter.close();
            return RequestBody.create(MEDIA_TYPE, buffer.readByteString());
        }
    }
}
