I developed an API using EVE.
This is the schema:
central_schema = {
'name': {
'type': 'string',
'required': True,
},
'id_account': {
'type': 'list',
}
}
I'm trying to send a list using retrofit 2. I tried the API using POSTMAN. Everytime I got this response:
id account "must be of list type"
I used many types of requests (PATCH, POST, PUT), but I still get the same error.
You can create Model class like below:
public class Model{
public String name;
public List<String> id_account;
}
And use it in retrofit 2.
It will produce below json:
{
"name": "xyz",
"id_account" : [
"1",
"2"
]
}

How To Parse Response of Multiple Types?
Key is like (suppose student_list is a key of list types when student_list is empty then it makes as a string like student_list=""), How to manage this types of response using Retrofit? I am using MVVM Model with retrofit.
My Response:
when I get Data into the List
{
"status": 200,
"data": [
{
"prod_month_total": 2989.61,
"product": "GAS"
},
{
"prod_month_total": 39566.22,
"product": "OIL"
},
{
"prod_month_total": 83912.55,
"product": "OTHER"
}
]
}
when List is Empty Then Response:
{"status":404,"data":"No result found"}
I am getting this Error:
java.lang.IllegalStateException: Expected BEGIN_ARRAY but was STRING at line 1 column 23 path $.data
first create the right model calss use this site http://www.jsonschema2pojo.org
than use
`if( reponce.isSucessful){
if(responce.status==200){
//code here
}
else{
// find the error
}
}else
{
//
}`
I need to build list of places (from response array create instance of place and finally receive list of places (place in json))?
How to parse it using Gson and Retrofit with custom deserializer?
I have following strucutre:

}
},

}
You can use Android Studio plugin RoboPOJOGenerator. It is very easy to make model classes from data.
This answer tells how to handle List response in retrofit.
Update
I don't think it is good idea to make custom deserializer just to parse a list. When you can filter or map list after getting response. It will take upto 3-4 lines of code.
If you don't want many classes. then you can safely delete Profile.java and Loc.java in your case, Gson will parse only data that you have declared in your pojo.
Make generic response class
You can make single class for handling all response by using Java Generics. See example.
public class ApiResponse<T> {
#SerializedName("error")
#Expose
private String error;
#SerializedName("success")
#Expose
private boolean success;
#SerializedName("response")
#Expose
private T response;
// make getter setters
}
Now in ApiService you can define response type. Like this
#GET("api/users/login")
Call<ApiResponse<ModelUser>> getUser();
#GET("api/users/login")
Call<ApiResponse<ModelCity>> getCity();
Thus you don't have to create 3 classes every time. This generic class will do work for all response.
I have one Registration Api which has error object in which it shows Errors Dynamically in Array.
This is the JsonFormat of Api :
{
"status_code": 422,
"status": "error",
"data": {
"errors": {
"password": [
"The password must be between 8 and 15 characters."
],
"mobile_no": [
"The mobile number has already been taken."
]
}
}
}
Here if a user forgot to write name then it will show username array in errors. So it changes dynamically.
My question is how I can set this type of errors in gson.I am using retrofit to call Api.
I did this in my Data class but it showing me errors.
#SerializedName("errors")
#Expose
JsonObject errorObject;
Iterator iterator=new Iterator() {
#Override
public boolean hasNext() {
Iterator keys=errorObject.keys();
if(keys.hasNext()){
}
}
#Override
public Object next() {
return null;
}
}
Please help me how can I getErrors using gson.Thank u
You can use Map to maintin the datastructure like this:
Type type = new TypeToken<Map<String, String>>(){}.getType();
Map<String, String> myMap = gson.fromJson(yourErrorsArrayHere, type);
and then just use myMap.get("your_error_key") to get the particular error.
I'm a newbie in Retrofit. How to parse the Json below using retrofit?
{
"data": {
"Aatrox": {
"id": 266,
"title": "a Espada Darkin",
"name": "Aatrox",
"key": "Aatrox"
},
"Thresh": {
"id": 412,
"title": "o Guardião das Correntes",
"name": "Thresh",
"key": "Thresh"
}
},
"type":"champion",
"version":"6.23.1"
}
You could make your model POJO contain a Map<String, Champion> to deserialize into, to deal with the dynamic keys.
Example:
public class ChampionData {
public Map<String, Champion> data;
public String type;
public String version;
}
public class Champion {
public int id;
public String title;
public String name;
public String key;
}
I'm not familiar with Retrofit besides that, but as someone in the comments said, the deserializing is done by Gson:
public ChampionData champions = new Gson().fromJson(json, ChampionData.class);
So to build on to the answer someone else posted, you can then do the following, assuming you've added the GsonConverterFactory:
public interface API {
#GET("path/to/endpoint")
Call<ChampionData> getChampionData();
}
Assuming Retrofit2, the first thing you need to do is call following when building your Retrofit instance.
addConverterFactory(GsonConverterFactory.create())
Then it's just a matter of writing a POJO (e.g. MyPojoClass) that maps to the json and then adding something like following to your Retrofit interface.
Call<MyPojoClass> makeRequest(<some params>);
Is there a way I can get my response to be a single object with an array of users using Eloquent?
For instance:
{
"results" : [
{ "email" : "test1#test.ca" },
{ "email" : "test2#test.ca" }
]
}
Current it outputs like this:
[
{
"email": "test1#test.ca",
},
{
"email": "test2#test.ca",
}
]
This is how I'm displaying users from my code:
$users = User::whereIn('number', $numbers)->select('email')->get();
return $users;
Which would be fine but I'm using Volley for Android using JSONObjectRequest but its failing when it tries to parse the JSON because it can't parse the array.
You can try it like this:
$users = User::whereIn('number', $numbers)->select('email')->get();
return Response::json(array('results' => $users));
