[英]Retrofit returns null error message with status 400
I have created an app to use REST api developed by me. 我已经创建了一个应用程序来使用我开发的REST api。 Android client is written with retrofit library.
Android客户端是使用改造库编写的。
there I have created an interface as ObjectIFaceAsync 在那里我创建了一个接口作为ObjectIFaceAsync
public interface ObjectIFaceAsync {
@POST("/")
public void addArea(
@Body Area area,
Callback<JsonElement> data
);
}
then I implemented it in a button click 然后我通过单击按钮实现
Area pojoArea = new Area();
pojoArea.setArea(area.getText().toString());
pojoArea.setDistrict(district.getText().toString());
pojoArea.setProvince(province.getText().toString());
pojoArea.setAreaType(areaType.getSelectedItem().toString());
RestAdapter restAdapter = new RestAdapter.Builder()
.setEndpoint(URLs.ENDPOINT + "/restaddarea")
.build();
ObjectIFaceAsync objectIFaceAsync = restAdapter.create(ObjectIFaceAsync.class);
try {
objectIFaceAsync.addArea(
pojoArea, new Callback<JsonElement>() {
@Override
public void success(JsonElement jsonElement,retrofit.client.Response response) {
if (jsonElement.getAsJsonObject()
.get("status").getAsString().equals("s")) {
//show a message
} else {
//show another message
}
}
@Override
public void failure(RetrofitError retrofitError) {
//show a failure message
}
}
);
} catch (Exception e) {
}
I have used the same endpoint to and sent a get request that is not having a JSON @Body. 我使用了相同的端点并发送了一个没有JSON @Body的get请求。 It works fine.
工作正常。 Here I always get an error.
在这里,我总是会出错。 means it always runs the failure method.
表示它总是运行失败方法。 I got displayed the
我展示了
retrofitError.getMessage();
and 和
retrofitError.getResponse().getStatuse();
They show null and 400 respectively. 它们分别显示null和400 。
Can someone tell what I have to do to get this corrected. 有人可以告诉我该怎么做才能更正此问题。 or what I have done wrong here.
或我在这里做错了什么。
thanks. 谢谢。
Use 采用
retrofitError.getBody()
to get String or 得到字符串或
retrofitError.getBodyAs(MyError.class)
if you want to map the error json to object 如果您想将错误json映射到对象
