这是ApiInterface.java
public interface ApiInterface {
@GET("bills/")
Call<SponsorsResult> getListOfSponsors(@Query("bill_id") String billId , @Query("session") String session, @Query("fields") String field);
}
这里是方法调用&回应：
ApiInterface apiService = ApiClient.getClient().create(ApiInterface.class);
Call<SponsorsResult> call = apiService.getListOfSponsors(AppConstants.ASSEMBLY_BILL_ID,AppConstants.SESSION,AppConstants.FIELD);
call.enqueue(new Callback<SponsorsResult>() {
@Override
public void onResponse(Call<SponsorsResult> call, Response<SponsorsResult> response) {
Log.d(TAG,"Number :"+response.raw());
List<Sponsor> sponsors = response.body().getSponsors();
Log.d(TAG,"Number of sponsors :"+ sponsors.size());
}
@Override
public void onFailure(Call<SponsorsResult> call, Throwable t) {
t.printStackTrace();
}
});
截至目前,它失败了&这是logcat输出：
com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was BEGIN_ARRAY at line 1 column 2 path $
它无法执行响应.指导我解析这个回复.
请尝试使用这个
@FormUrlEncoded
@POST("api/sponsors")
Call<List<SponsorsResult>> getStatesAndDistrict(
@Field("xyz") String field1
);
Call <List<SponsorsResult>> call = service.getSponsorsValue();
call.enqueue(new Callback<List<SponsorsResult>>() {
@Override
public void onResponse(Call<List<SponsorsResult>> call, Response<List<SponsorsResult>> response) {
List<SponsorsResult> rs = response.body();
}
@Override
public void onFailure(Call<List<SponsorsResult>> call, Throwable t) {
}
});
class SponsorsResult {
@SerializedName("sponsors")
private List<SponsorsValue> sponsors;
public List<SponsorsValue> getSponsors() {
return sponsors;
}
}
class SponsorsValue{
@SerializedName("leg_id")
@Expose
private String legId;
@SerializedName("type")
@Expose
private String type;
@SerializedName("name")
@Expose
private String name;
public String getLegId() {
return legId;
}
public void setLegId(String legId) {
this.legId = legId;
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
如果您遇到任何问题,请告诉我.
