改型-预期为BEGIN_ARRAY，但为BEGIN_OBJECT? [英] Retrofit - Expected BEGIN_ARRAY but was BEGIN_OBJECT?
本文介绍了改型-预期为BEGIN_ARRAY，但为BEGIN_OBJECT?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我通过类似波纹管的翻修得到了json的结果:
I am getting a json result from service with retrofit like bellow :
{
"result": {
"totalCount": 15,
"resultCount": 2,
"offset": 0,
"limit": 2,
"products": [
{
"id": 10081,
"name": "prod",
"pictureUrl": "url",
"price": 1,
"url": "url",
"briefDescription": "test",
"description": "test",
"pictures": [],
"categoryTitle": "s s",
"categoryId": 53,
"extraInfo": {
"productProperties": [
{
"id": 88,
"value": "6",
"measurementUnit": "s",
"title": "s"
},
{
"id": 89,
"value": "2",
"measurementUnit": "s",
"title": "s s"
},
{
"id": 90,
"value": "2",
"measurementUnit": "s",
"title": "s s s s"
},
{
"id": 91,
"value": "",
"measurementUnit": "",
"title": "s s"
},
{
"id": 92,
"value": "",
"measurementUnit": "",
"title": "s s"
},
{
"id": 93,
"value": "",
"measurementUnit": "",
"title": "s"
},
{
"id": 94,
"value": "",
"measurementUnit": "",
"title": "s"
}
],
"published": false,
"preparationTime": 1,
"keywords": "",
"quantity": 0,
"status": 1
}
},
{
"id": 51,
"name": "nam3",
"pictureUrl": "url",
"price": 495000,
"url": "url",
"briefDescription": "sdsds",
"description": "-",
"pictures": [],
"categoryTitle": "x x x",
"categoryId": 179,
"extraInfo": {
"productProperties": [
{
"id": 67,
"value": "1000",
"measurementUnit": "x",
"title": "x x"
},
{
"id": 68,
"value": "1050",
"measurementUnit": "s",
"title": "x x x"
},
{
"id": 69,
"value": "",
"measurementUnit": "",
"title": "x x"
},
{
"id": 70,
"value": "",
"measurementUnit": "",
"title": "x x"
},
{
"id": 71,
"value": "",
"measurementUnit": "",
"title": "xxxx"
}
],
"published": true,
"preparationTime": 2,
"keywords": "Aswddfe",
"quantity": 93,
"status": 1
}
}
]
}
}
我变得像retrofit一样吼叫:
RetrofitApi.getVendorAdminApi()
.getAdminProductss(userToken, limit, pageNumber, filters)
.enqueue(new Callback<List<ProductsModel>>() {
@Override
public void onResponse(Call<List<ProductsModel>> call, Response<List<ProductsModel>> response) {
if (response.isSuccessful()) {
resultListener.onSuccess(response.body());
} else {
resultListener.onFailure();
}
}
@Override
public void onFailure(Call<List<ProductsModel>> call, Throwable t) {
resultListener.onFailure();
t.printStackTrace();
}
});
但是说我:
Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 2 path $
下面是我的模特:
public class ProductsModel {
@SerializedName("result")
@Expose
private ResultProducts result;
public ResultProducts getResult() {
return result;
}
public void setResult(ResultProducts result) {
this.result = result;
}
}
推荐答案
您的问题是Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 2 path $
因此将
List<ProductsModel>更改为ProductsModel.
-
如果
JSON是JSONArray，则可以将其解析为List(如List<ProductsModel>).If
JSONisJSONArray,you can parse it toList(likeList<ProductsModel>).如果
JSON是JSONObject，则可以将其解析为Object(如ProductsModel).If
JSONisJSONObject,you can parse it toObject(likeProductsModel).更改为此.
@Override public void onResponse(Call<ProductsModel> call, Response<ProductsModel> response) { if (response.isSuccessful()) { resultListener.onSuccess(response.body()); } else { resultListener.onFailure(); } }还有
Call<ProductsModel> getAdminProductss();这篇关于改型-预期为BEGIN_ARRAY，但为BEGIN_OBJECT?的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
