I'm trying to pull data by connecting to a web service using Retrofit. The web service I will use in my application is encrypted. So I can access it with Bearer token. I also need to renew the Bearer token. I did get Bearer tokens. How can I connect to web service with this Bearer token I got?
Postman : enter image description here
ServiceAPI :
interface ServiceAPI {
@FormUrlEncoded
@POST("GetToken")
fun getGetToken(@Field("grant_type")grant_type:String, @Field("username") username:String, @Field("password") password:String):Call<Token>
@GET("api/Users")
fun getUsers(@Header("Authorization") authorization: String): Call<UsersModel>
}
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
getServiceExample()
}
fun getServiceExample(){
val BASE_URL = "https://www.exampleserviceid.com/"
val api = Retrofit.Builder()
.baseUrl(BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.build()
val service = api.create(ServiceAPI::class.java).getGetToken("password","myusername","mypassword")
service.enqueue(object : Callback<Token>{
override fun onResponse(call: Call<Token>, response: Response<Token>) {
if (response.isSuccessful){
val gettoken: Token? = response.body()
val token = gettoken?.accessToken // This is how I get the Bearer token
}
}
override fun onFailure(call: Call<Token>, t: Throwable) {
TODO("Not yet implemented")
}
})
}
Token :
class Token : Serializable {
@SerializedName("access_token")
@Expose
var accessToken: String? = null
@SerializedName("token_type")
@Expose
var tokenType: String? = null
@SerializedName("expires_in")
@Expose
var expiresIn: Int? = null
constructor() {}
/**
*
* @param tokenType
* @param accessToken
* @param expiresIn
*/
constructor(accessToken: String?, tokenType: String?, expiresIn: Int?) : super() {
this.accessToken = accessToken
this.tokenType = tokenType
this.expiresIn = expiresIn
}
}
UsersModel:
class UsersModel : Serializable {
@SerializedName("username")
@Expose
var username: String? = null
@SerializedName("userage")
@Expose
var userage: String? = null
constructor() {}
constructor(username: String?, userage: String?) : super() {
this.username= username
this.userage= userage
}
}
How can I connect to web service with this Bearer token I got?
Update :
fun getServiceExample(){
val BASE_URL = "https://www.exampleserviceid.com/"
val api = Retrofit.Builder()
.baseUrl(BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.build()
val service = api.create(ServiceAPI::class.java).getGetToken("password","myusername","mypassword")
service.enqueue(object : Callback<Token>{
override fun onResponse(call: Call<Token>, response: Response<Token>) {
if (response.isSuccessful){
val gettoken: Token? = response.body()
val token = gettoken?.accessToken // This is how I get the Bearer token
val httpClient: OkHttpClient.Builder =OkHttpClient.Builder()
.callTimeout(60, TimeUnit.SECONDS)
.connectTimeout(60, TimeUnit.SECONDS)
.readTimeout(60, TimeUnit.SECONDS)
.writeTimeout(60, TimeUnit.SECONDS)
httpClient.addInterceptor(object: Interceptor {
override fun intercept(chain: Interceptor.Chain): okhttp3.Response {
val original = chain.request();
val request = original.newBuilder()
.header("Authorization","Bearer " + token)
.method(original.method(), original.body())
.build();
val Log = Logger.getLogger(MainFragment::class.java.name)
Log.warning("Bearer " + token)
return chain.proceed(request);
}
})
val client = httpClient.build();
val retrofit = Retrofit.Builder()
.baseUrl(BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.client(client)
.build();
val service2 = retrofit.create(ServiceAPI::class.java).getUsers()
service2.enqueue(object : Callback<UsersModel>{
override fun onResponse(call: Call<UsersModel>, response: Response<UsersModel>) {
if (response.isSuccessful){
val usersmodeltoken: UsersModel? = response.body()
val usernametoken = usersmodeltoken?.username
Toast.makeText(context, usernametoken, Toast.LENGTH_SHORT).show()
}
}
override fun onFailure(call: Call<UsersModel>, t: Throwable) {
/*
TODO("Not yet implemented")
*/
}
})
}
}
override fun onFailure(call: Call<Token>, t: Throwable) {
TODO("Not yet implemented")
}
})
}

Solution :
@GET("api/Users")
fun getUsers(@Header("Authorization") authorization: String): Call<List<UsersModel>>
val service2 = retrofit.create(ServiceAPI::class.java).getUsers("Bearer "+tokennn)
service2.enqueue(object : Callback<List<UsersModel>> {
override fun onResponse(call: Call<List<UsersModel>?>?, response: Response<List<UsersModel>?>?) {
if (response != null) {
if (response.isSuccessful){
val data= response.body()
if (data!= null) {
val recyclerView = findViewById<RecyclerView>(R.id.recyclerview)
recyclerView.layoutManager = LinearLayoutManager(this)
recyclerView.adapter = ExampleAdapter(data)
}
}
}
}
override fun onFailure(call: Call<List<UsersModel>?>?, t: Throwable?) {
// TODO("Not yet implemented")
}
})
