How to add authentication token in header in Picasso library

Question

I am using the picasso library to download the bitmap so in the api I need to pass the token in the headers. I tried below code from this thread Android Picasso

Answer 1

I had the same problem but in my case I had forgotten I had an self-signed certificate on my server so OkHttp was getting the certificate and then refusing to retrieve any images. Consequently from the server side it looked like Picasso was not making any requests.

So the fix was to create an unsafe OkHttp client that doesn't test certificates:

static OkHttpClient getUnsafeOkHttpClient() {
  try {
      // Create a trust manager that does not validate certificate chains
      final TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
          @Override
          public void checkClientTrusted(java.security.cert.X509Certificate[] chain,
                  String authType) throws CertificateException {
          }

          @Override
          public void checkServerTrusted(java.security.cert.X509Certificate[] chain,
                  String authType) throws CertificateException {
          }

          @Override
          public java.security.cert.X509Certificate[] getAcceptedIssuers() {
              return null;
          }
      } };

      // Install the all-trusting trust manager
      final SSLContext sslContext = SSLContext.getInstance("SSL");
      sslContext.init(null, trustAllCerts, new java.security.SecureRandom());
      // Create an ssl socket factory with our all-trusting manager
      final SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();

      OkHttpClient okHttpClient = new OkHttpClient();
      okHttpClient.setSslSocketFactory(sslSocketFactory);
      okHttpClient.setHostnameVerifier(new HostnameVerifier() {
          @Override
          public boolean verify(String hostname, SSLSession session) {
              return true;
          }
      });

      return okHttpClient;
  } catch (Exception e) {
      throw new RuntimeException(e);
  }
}

Then use it in my CustomOkHttpDownloader:

static class CustomOkHttpDownloader extends OkHttpDownloader {

    private String accessToken;

    public CustomOkHttpDownloader(Context context, String accessToken) {
        super(getUnsafeOkHttpClient());
        this.accessToken = accessToken;
    }

    @Override
    protected HttpURLConnection openConnection(final Uri uri) throws IOException {
        HttpURLConnection connection = super.openConnection(uri);
        connection.setRequestProperty("Authorization", "Bearer " + accessToken);
        Log.d(LOG_TAG, "Creating connection for " + uri + " with " + accessToken);
        return connection;
    }
}
