我正在使用Gson和Retrofit解析JSON字符串。我有这个JSON字符串:
{"message":["Email has already been taken"]}
我仍然得到以下异常,并且不知道原因:
java.io.EOFException: End of input at line 1 column 1 path $
at com.google.gson.stream.JsonReader.nextNonWhitespace(JsonReader.java:1393)
at com.google.gson.stream.JsonReader.doPeek(JsonReader.java:549)
at com.google.gson.stream.JsonReader.peek(JsonReader.java:425)
at com.google.gson.internal.bind.ReflectiveTypeAdapterFactory$Adapter.read(ReflectiveTypeAdapterFactory.java:205)
at com.google.gson.TypeAdapter.fromJson(TypeAdapter.java:260)
at com.google.gson.TypeAdapter.fromJson(TypeAdapter.java:273)
知道如何获得message
字段价值的人请帮助我。
BaseApiDto.java
public class BaseApiDto {
@SerializedName("message")
public String[] message;
public String getError() {
return message[0];
}
}
HandErrorUtils.java
public static void handleError(FragmentActivity activity, Throwable e) {
String msg = null;
if(e instanceof HttpException){
// Error message in json
Gson gson = new Gson();
TypeAdapter<BaseApiDto> adapter = gson.getAdapter(BaseApiDto.class);
ResponseBody body = ((HttpException) e).response().errorBody();
// Status code
HttpException httpException = (HttpException) e;
int statusCode = httpException.code();
if (statusCode == 500) {
showErrorDialog(activity, activity.getString(R.string.dialog_msg_error_401), true);
} else if (statusCode == 401) {
showErrorDialog(activity, activity.getString(R.string.dialog_msg_error_401), true);
} else {
try {
Timber.w("body.string() " + body.string());
// TODO : EXCEPTION HAPPEN IN HERE
BaseApiDto errorDto = adapter.fromJson(body.string());
msg = errorDto.getError();
Timber.w("msg " + msg);
} catch (Exception ex) {
// TODO : EXCEPTION HAPPEN IN HERE
ex.printStackTrace();
}
showErrorDialog(activity, msg, false);
}
}
}
更新我将body.toString()
分配给变量,不知何故有效。
String response = body.string();
BaseApiDto errorDto = adapter.fromJson(response);
答案 0 :(得分:1)
之所以有效,是因为我没有两次致电body.string()
。
我将body.toString()
分配给变量,以某种方式起作用。
String response = body.string();
BaseApiDto errorDto = adapter.fromJson(response);
