Get password protected json via Retrofit2 in Android - android

I successfully consume a json without password protected but admin set a password and I cannot get data via Retrofit2. How can I fix this? Please share your ideas. Thanks.

Configure your OkHttpClient with a new Authenticator to handle Basic Auth as follows:
OkHttpClient client = new OkHttpClient.Builder()
.authenticator(new Authenticator() {
#Override
public Request authenticate(Route route, Response response) throws IOException {
String credential = Credentials.basic("username", "password");
return response.request().newBuilder()
.header("Authorization", credential)
.build();
}
}).build();
Then use the OkHttpClient in Retrofit as follows:
new Retrofit.Builder()
.baseUrl("url")
.addConverterFactory(GsonConverterFactory.create())
.client(client)
.build();

How to refresh token in AWS Cognito using Android SDK?

I have been searching for the proper way to refresh token after the token generated by the AWS as Federated Identity has expired. My application uses cognito to log, and sign up users and then take the Access Token and then hit the apis using RetroFit.
Retrofit call
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient client = new OkHttpClient.Builder().addInterceptor(interceptor).build();
//end
OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
httpClient.readTimeout(45, TimeUnit.SECONDS);
httpClient.connectTimeout(120, TimeUnit.SECONDS);
httpClient.interceptors().add(new AuthInterceptor());
httpClient.addInterceptor(interceptor); //debugging
httpClient.addInterceptor(new Interceptor() {
#Override
public Response intercept(Chain chain) throws IOException {
Request original = chain.request();
// Customize the request
Request request = original.newBuilder()
.header("Content-type", "application/json")
.header("Authorization", "auth-token")
.header("Accept", "application/json")
.header("deviceType", "android") //experimental
.header("Version", "v1")
.method(original.method(), original.body())
.build();
Response response = chain.proceed(request);
return response;
}
});
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(BuildConfig.BASE_URL)
.client(httpClient.build())
.addConverterFactory(ToStringConverterFactory.create())

}

I am stuck this problem., The token expires in 1 hour and then I cant do anything. There is not information available to refresh token in Android. All I can see is that Android AWS SDK refreshes the token by itself as long as Refresh Token as validity.
So after searching online for three days, I got the answer.
All you have to do is call the getSession(..) to get the refreshed tokens.
Here how it is done:
Cognito.getPool().getUser().getSession(new CognitoLogin(BaseApplication.getApp().getApplicationContext(), Cognito.getCurrUser(), Cognito.getPasswordForFirstTimeLogin()));
String newtoken = Cognito.getInstance().getCurrSession().getAccessToken().getJWTToken();

How to use postman's aws-signature(using aws-iot rest api) into android application?

How to use Authorization Token token=A-123456789qwertyuio12 Header in Retrofit 2.0

im trying to consume an api that has that authorization header, i can get a 200 response in Postman with all data but cant get it to work in retrofit
May be you need add the Token using OkHttp Interceptor.
OkHttpClient client = new OkHttpClient.Builder()
.addNetworkInterceptor(mTokenInterceptor)
.build();
then add it to Retrofit:
Retrofit retrofit = new Retrofit.Builder()
.client(client)
.baseUrl(base_url)
.build();
the mTokenInterceptor:
Interceptor mTokenInterceptor = new Interceptor() {
#Override
public Response intercept(Chain chain) throws IOException {
Request request = chain.request();
if (mToken != null) {
Request.Builder requestBuilder = request.newBuilder()
.addHeader("Authorization", mToken);
Request newRequest = requestBuilder.build();
return chain.proceed(newRequest);
}
return chain.proceed(request);
}
};
when you get the Token, just assign the mToken,
You can try something like below, just a crude example
#GET("your server url goes here")
Call<Your_Model_Class> getServerData(#Header("Authorization") String token);
Pass your token to getServerData method.

Retrofit interceptor error

I want to add facebook access token into retrofit (2 beta 3) request, but the access token does not added.
I can add interceptor to retrofit 1.9 successfully but in retrofit 2 it has error, Is there any solution?
protected Retrofit getRestAdapter() {
OkHttpClient client = new OkHttpClient.Builder()
.addInterceptor(
new Interceptor() {
#Override
public Response intercept(Interceptor.Chain chain) throws IOException {
Request original = chain.request();
String sessionId = getSessionId(); // get access token
// Request customization: add request headers
Request.Builder requestBuilder = original.newBuilder()
.header("Cookie", sessionId)
.method(original.method(), original.body());
Request request = requestBuilder.build();
return chain.proceed(request);
}
})
.build();
if (retrofit == null) {
retrofit = new Retrofit.Builder()
.baseUrl("http://tbkha.com/api/")
.addConverterFactory(GsonConverterFactory.create())
.client(client)
.build();
}
return retrofit;
}
In retrofit retrofit 2.0 you add intercepter like this:
HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
logging.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient client = new OkHttpClient.Builder()
.addInterceptor(logging).build();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(baseURL)
.client(client)
.build();
