Retrofit 2.0 如何获得反序列化错误 response.body
我用
Retrofit 2.0.0-beta1
.
在测试中，我有一个替代脚本并期望错误 HTTP 400
我想拥有
但
MyError 不漂浮 - 我只在这里看到它
但它没有给我 MyError 作为对象
</myerror>

我想拥有
retrofit.Response<myerror> response
但
response.body// == null
MyError 不漂浮 - 我只在这里看到它
response.errorBody//.string//
但它没有给我 MyError 作为对象
</myerror>

更新 Retrofit 2 beta3
:
同步 - 没有改变
异步参数 Retrofit 被删除了 onResponse

上班 retrofit:2.5.0.
阅读文本 charStream, 它会给你一个字符串，然后分析到 JSONObject.
Adios。

如果你的结构 error JSON 看起来
{
"error": {
"status": "The email field is required."
}
}
My ErrorRespnce.java
public class ErrorResponce {
@SerializedName/"error"/
@Expose
private ErrorStatus error;
public ErrorStatus getError// {
return error;
}
public void setError/ErrorStatus error/ {
this.error = error;
}
}
这是我的错误状态类
public class ErrorStatus {
@SerializedName/"status"/
@Expose
private String status;
public String getStatus// {
return status;
}
public void setStatus/String status/ {
this.status = status;
}
}
现在我们需要一个可以应对我们的课程 json.
public class ErrorUtils {
public static ErrorResponce parseError /Response response/{
Converter<responsebody ,="" errorresponce=""> converter = ApiClient.getClient//.responseBodyConverter/ErrorResponce.class , new Annotation[0]/;
ErrorResponce errorResponce;
try{
errorResponce = converter.convert/response.errorBody///;
}catch /IOException e/{
return new ErrorResponce//;
}
return errorResponce;
}
}
现在我们可以查看我们的答案 retrofit api 称呼
private void registrationRequest/String name , String email , String password , String c_password/{
final Call<registrationresponce> registrationResponceCall = apiInterface.getRegistration/name , email , password , c_password/;
registrationResponceCall.enqueue/new Callback<registrationresponce>// {
@Override
public void onResponse/Call<registrationresponce> call, Response<registrationresponce> response/ {
if /response.code// == 200/{
}else if /response.code// == 401/{
ErrorResponce errorResponce = ErrorUtils.parseError/response/;
Toast.makeText/MainActivity.this, ""+errorResponce.getError//.getStatus//, Toast.LENGTH_SHORT/.show//;
}
}
@Override
public void onFailure/Call<registrationresponce> call, Throwable t/ {
}
}/;
}
这就是现在你可以展示你的吐司
</registrationresponce></registrationresponce></registrationresponce></registrationresponce></registrationresponce></responsebody>

错误 APIError = APIErrorUtils.parseError/response/;
如果一个 /error.getStatus// = = 400/{
