在改造2
中处理不同的JSON字段类型响应需要帮助serverapi返回2种不同类型的响应,并且都在Http 200中确定:
如果成功,服务器将返回此响应:
{"error_code":"0000","error_message":"success!",item_id:"SHVR25","description":{"DENOMINATION":"25","PRICE":"28000"}}
不成功,:
{"error_code":"1111","error_message":"failed!",item_id:"SHVR10","description":""}
POJO Bill
public class Bill{
@SerializedName("error_code")
@Expose
public String errorCode;
@SerializedName("error_message")
@Expose
public String errorMessage;
@SerializedName("item_id")
@Expose
public String itemId;
@SerializedName("description")
@Expose
public Description descriptionss;
public String getErrorCode() {
return errorCode;
}
public void setErrorCode(String errorCode) {
this.errorCode = errorCode;
}
public String getErrorMessage() {
return errorMessage;
}
public void setErrorMessage(String errorMessage) {
this.errorMessage = errorMessage;
}
public String getItemId() {
return itemId;
}
public void setItemId(String itemId) {
this.itemId = itemId;
}
public Description getDescriptionss() {
return descriptionss;
}
public void setDescriptionss(Description descriptionss) {
this.descriptionss = descriptionss;
}
public Description getDescriptionss() {
return descriptionss;
}
}
POJO说明
public class Description{
@SerializedName("DENOMINATION")
@Expose
public String dENOMINATION;
@SerializedName("PRICE")
@Expose
public String pRICE;
public String getdENOMINATION() {
return dENOMINATION;
}
public void setdENOMINATION(String dENOMINATION) {
this.dENOMINATION = dENOMINATION;
}
public String getpRICE() {
return pRICE;
}
public void setpRICE(String pRICE) {
this.pRICE = pRICE;
}
}
回调
@Override
public void onResponse(Call<Bill> call, Response<Bill> response) {
if(response.isSuccessful()){
Bill bill= response.body();
Timber.d("bill contains=="+bill.toString());
}
}else{
Timber.d("response is not success!");}
}
@Override
public void onFailure(Call<JsonElement> call, Throwable t) {
Timber.e("retrofit failed.... throwable:"+t.toString());
}
}
);
实际上我的问题类似于这种情况:How to handle response which can be different Type in Retrofit 2
问题:回叫总是调用onFailed并说java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 236 path $.description
问题: 如何使用POJO作为回调而不是JsonElement处理不同类型的响应改进,而不更改服务器响应?
我试过这个 How to handle Dynamic JSON in Retrofit?(但它适用于改造1)和How to handle response which can be different Type in Retrofit 2(它使用JsonElement作为回调响应)

使用对象类型
@SerializedName("description")
@Expose
public Object descriptionss;

每当您按下api时,都有两种可能性。成功或失败。 为了获得错误体,我们使用response.errorBody并解析错误体,其kotlin代码如下所示:
val loginRequestError = { response: Response<YourResponse> ->
SocietyRetrofit.retrofit.responseBodyConverter<Error>(Error::class.java, arrayOf<Annotation>()).convert(response.errorBody())
}
数据类为:
data class Error(var error: String, var message: String)
错误类包含您的api错误包含的字段。
要获取错误消息,我们可以这样调用方法:
val errorMessage = loginRequestError(<Your api response>).message
