REST POST HTTP JSON对象400错误Android [英] REST POST HTTP JSON Objects 400 error Android
问题描述
由于我收到了一些不好的评论，我正在重写这个问题...
Since I got some bad reviews I am rewriting this question...
我有一个HTTP REST服务器和一个客户端（Android应用程序）。我编写了几个工作正常的API，但有一个给我400错误，如果我在服务器中放置一个断点，它甚至不会触发它。所以，我想了解它失败的原因:( ...
I have an HTTP REST server and a client (Android app). I have programmed several APIs that work just fine, however there is one that is giving me a 400 error, and if I put a breakpoint in the server, it does not even triggers it. So, I would like to understand why it fails :( ...
这很简单，我有一个名为Alarm的值对象，带有一些属性，我想要的POST到服务器以注册数据库中的对象。
It is very simple, I have a value object called Alarm with a few attributes, that I want to POST to the server for registration of object in the database.
这是输出：
Callback failure for call to http://10.0.0.3:8080/...
java.io.IOException: Unexpected code Response{protocol=http/1.1, code=400, message=, url=http://10.0.0.3:8080/BiTrack_API/api/assets/registerAlarm}

这是我的客户端Android按钮监听器：
This is my client side Android button listener:
View.OnClickListener addAlarmAction = new View.OnClickListener() {
@Override
public void onClick(View v) {
try {
alarm.setThreshold(Float.parseFloat(thresholdEditText.getText().toString()));
String alarmJson = j.makeJsonBodyForAlarmRegistration(alarm);
tagLinearLayout.setVisibility(view.GONE);
operatorLinearLayout.setVisibility(view.GONE);
thresholdLinearLayout.setVisibility(view.GONE);
assetSpinner.setSelection(0);
r.attemptAddNewAlarm(alarmJson,
new Callback() {
@Override public void onFailure(Call call, IOException e) {
e.printStackTrace();
}
@Override public void onResponse(Call call, Response response) throws IOException {
try (final ResponseBody responseBody = response.body()) {
if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);
Headers responseHeaders = response.headers();
for (int i = 0, size = responseHeaders.size(); i < size; i++) {
System.out.println(responseHeaders.name(i) + ": " + responseHeaders.value(i));
}
final String responseBodyString = responseBody.string();
final int resultCode = response.code();
try {
getActivity().runOnUiThread(new Runnable() {
@Override
public void run() {
Log.i("BiTrack", "attemptAddNewAlarm RESULT: " + resultCode);
executeAlarmRegistration(resultCode);
}
});
} catch (Exception e) {
e.printStackTrace();
}
}
}
});
} catch (Exception e) {
e.printStackTrace();
}
}
};
这是我在客户端为POST生成Json主体的代码：
This is the code where I generate the Json body for the POST in the client:
public String makeJsonBodyForAlarmRegistration (Alarm alarm) {
Gson gson = new Gson();
String jsonAlarm = gson.toJson(alarm);
return jsonAlarm;
}
这是客户端（Android）中的实际POST代码side：
This is the actual POST code in the client (Android) side:
public void attemptAddNewAlarm(String json, Callback callback) throws Exception {
final OkHttpClient client = new OkHttpClient();
RequestBody body = RequestBody.create(JSON, json);
Request request = new Request.Builder()
.url(WEB_SERVER + "BiTrack_API/api/assets/registerAlarm")
.post(body)
.build();
client.newCall(request).enqueue(callback);
}
这是我的服务器端代码：
This is my server side code:
@POST
@Path("/registerAlarm")
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public Response registerAlarm(Alarm alarm) {
System.out.println("Received API Call: registerAlarm for alarm tagId: " + alarm.getTagId() + " operatorId: " + alarm.getOperatorId() + " treshold: " + alarm.getThreshold());
DataProcessor dp = new DataProcessor();
AssetUpdateDAO aDAO = new AssetUpdateDAO();
ArrayList<Alarm> customerAlarms = aDAO.getUserAlarmsForAsset(alarm.getUserId(), alarm.getAssetId());
if (dp.isNewAlarmDuplicate(customerAlarms, alarm)) {
return Response.status(480).build(); // duplicated error
} else {
int response = aDAO.insertAssetUserAlarm(alarm.getUserId(), alarm.getAssetId(), alarm.getTagId(), alarm.getOperatorId(), alarm.getThreshold());
if (response == -5) {
return Response.status(484).build(); // something went wrong while inserting alarm into db
} else {
return Response.status(200).build();
}
}
}
这是我的警报值对象（客户端和服务器中的相同类）：
This is my Alarm value object (identical class in client and server):
public class Alarm {
public Alarm() {
}
protected int id;
protected int userId;
protected int assetId;
protected int tagId;
protected int operatorId;
protected float threshold;
protected String networkAssetCode;
public String getNetworkAssetCode() {
return networkAssetCode;
}
public void setNetworkAssetCode(String networkAssetCode) {
this.networkAssetCode = networkAssetCode;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public int getUserId() {
return userId;
}
public void setUserId(int userId) {
this.userId = userId;
}
public int getAssetId() {
return assetId;
}
public void setAssetId(int assetId) {
this.assetId = assetId;
}
public int getTagId() {
return tagId;
}
public void setTagId(int tagId) {
this.tagId = tagId;
}
public int getOperatorId() {
return operatorId;
}
public void setOperatorId(int operatorId) {
this.operatorId = operatorId;
}
public float getThreshold() {
return threshold;
}
public void setThreshold(float threshold) {
this.threshold = threshold;
}
}
我非常感谢任何帮助.. 。
I really appreciate any help...
推荐答案
我发现了这个问题！在48小时后寻找不可能的事情，发现我在服务器端的对象属性上做了一个小的更新，但没有在客户端复制...
I found the issue! After 48 hours looking for the impossible, discovered that I had done a small update at the object attribute at the server side that had not been replicated in the client side...
