Question

我试图从API中获取一些项目，如下所示：

{ "picklist": [ 
{ "name": "Abkhazia", "id": "a0511000002gxF1AAI" },
{ "name": "Afghanistan", "id": "a0511000002gxF2AAI" },
{ "name": "Akrotiri and Dhekelia", "id": "a0511000002gxF3AAI" },
{ "name": "Albania", "id": "a0511000002gxF5AAI" },
{ "name": "Algeria", "id": "a0511000002gxF6AAI" },
{ "name": "American Samoa", "id": "a0511000002gxF7AAI" }
] }

我尝试过这样取道：

public interface MyAPI {
    @GET("/?country=true")
    Call<List<User>> getUsers();
}

但是因为这个表有一个名字会引发异常（至少我认为这就是原因）：

java.lang.IllegalStateException:
Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 3 path $

我该如何解决？

您应该针对此案例使用自定义响应：

public interface MyAPI {
    @GET("/?country=true")
    Call<APIResponse> getUsers();
}

class APIResponse {
    @JsonProperty("picklist") List<User> userList;
}

@JsonProperty是Jackson annotation的位置。如果您没有此注释，则可以随时将APIResponse更改为：

class APIResponse {
    List<User> picklist;
}
