java.lang.IllegalStateException:预期BEGIN_OBJECT，但在第 1 行第 2 列路

Question

我是改造的新手。以下是我获取供应商列表的代码

示例 JSON 响应是 json 数组，而不是 json 对象

[
{
"Key" : "1",
"Value" : "xyz"
},
{
"Key" : "2",
"Value" : "abc"
}
]

下面是我的代码

private void callToRetrofit() {
ApiInterface apiInterface = ApiClient.getApiClient()
.create(ApiInterface.class);
Call<List<SD_Checklist_Supplier_Model>> call = apiInterface.getVendors();
call.enqueue(new Callback<List<SD_Checklist_Supplier_Model>>() {
@Override
public void onResponse(Call<List<SD_Checklist_Supplier_Model>> call, Response<List<SD_Checklist_Supplier_Model>> response) {
Log.v("onResponse", " : ok" +  response == null ? " null" : "okkkk" + response.toString());
}
@Override
public void onFailure(Call<List<SD_Checklist_Supplier_Model>> call, Throwable t) {
Log.v("onFailure", " : " + t.toString());
}
});
}

模型类

public class SD_Checklist_Supplier_Model {
@SerializedName("Key")
private String supplierID;
@SerializedName("Value")
private String supplierName;
private boolean isSupplierSelected;
public String getSupplierID() {
return supplierID;
}
public void setSupplierID(String supplierID) {
this.supplierID = supplierID;
}
public String getSupplierName() {
return supplierName;
}
public void setSupplierName(String supplierName) {
this.supplierName = supplierName;
}
public boolean isSupplierSelected() {
return isSupplierSelected;
}
public void setSupplierSelected(boolean supplierSelected) {
isSupplierSelected = supplierSelected;
}
}

目前，我正在得到

com.google.gson.JsonSyntaxException： java.lang.IllegalStateException： 预期BEGIN_OBJECT，但在第 1 行第 2 列路径 $ 处BEGIN_ARRAY

请帮助我。

Answer 1

您对 API 调用的响应是一个列表，您没有分配给列表。

更改您的代码

Call<SD_Checklist_Supplier_Model> call = apiInterface.getVendors();

如

Call<List<SD_Checklist_Supplier_Model>> call = apiInterface.getVendors();
