I am using Picasso to download images and show them from the server. I need to set basic Aucathention to my requests. And because of that i used this:
'com.jakewharton.picasso:picasso2-okhttp3-downloader:1.1.0'
and my code is:
String url = "images/download/" + images.getiId();
OkHttpClient client = new OkHttpClient.Builder()
.addInterceptor(new Interceptor() {
#Override
public Response intercept(Chain chain) throws IOException {
Request newRequest = chain.request().newBuilder()
.addHeader("user_auth", user_auth)
.addHeader("user_password", user_pass)
.build();
return chain.proceed(newRequest);
}
})
.build();
Picasso picasso = new Picasso.Builder(context)
.downloader(new OkHttp3Downloader(client))
.build();
picasso.load(url)
.error(R.drawable.error_icon_128)
.into(view);
}
but every time it can't download images And I can't see response code from the server. How can I see response code?
Thank you.

I saw this question asked so many times but mine is with different case. Please dont mark it as duplicate.
Following is my client for retrofit. Which works perfectly fine when we're using apk. But as soon as we convert it to MDX for citrix/secure hub we are facing this end of stream error.
I have also tried this with volley but am getting same error. As you can see that I have tried all the interceptor and all for retrofit.
Already tried following interceptor.
addHeader("Connection", "close")
retryOnConnectionFailure(true)
So my question is what is happening exactly? Why is it working in apk and not on MDX.
public static Retrofit getClient() {
//Basic Auth
String authToken = null;
if (!TextUtils.isEmpty(AppConfig.username) &&
!TextUtils.isEmpty(AppConfig.password)) {
authToken = Credentials.basic((String) AppConfig.username, (String) AppConfig.password);
}
//Create a new Interceptor.
final String finalAuthToken = authToken;
Interceptor headerAuthorizationInterceptor = new Interceptor() {
#Override
public okhttp3.Response intercept(Chain chain) throws IOException {
okhttp3.Request request = chain.request();
Headers headers = request.headers().newBuilder()
// .add("Authorization", finalAuthToken)
.add("Connection", "close").build();
request = request.newBuilder().headers(headers).build();
return chain.proceed(request);
}
};
//TO be added in milliseconds
List < Protocol > protos = new ArrayList < > ();
protos.add(Protocol.HTTP_2);
protos.add(Protocol.HTTP_1_1);
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient client = new OkHttpClient.Builder()
.addInterceptor(interceptor)
.protocols(protos)
.retryOnConnectionFailure(true) //FIRST TRY : Added this line after getting Unexpected end of stream error.
.connectTimeout(180, TimeUnit.SECONDS)
.readTimeout(180, TimeUnit.SECONDS)
.writeTimeout(180, TimeUnit.SECONDS)
//.addInterceptor(new GzipRequestInterceptor())
// THIRD TRY : Added this new interceptor for end of stream error
/*.addInterceptor(new Interceptor() {
#NonNull
#Override
public Response intercept(#NonNull Chain chain) throws IOException {
Request request = chain.request().newBuilder()
.addHeader("Connection", "close")
.addHeader("Transfer-Encoding", "chunked")
//.addHeader("Accept-Encoding", "gzip")
.build();
return chain.proceed(request);
}
})*/
//.addInterceptor(headerAuthorizationInterceptor) // SECOND TRY : Added this line after getting Unexpected end of stream error. fot connection close
//ABOVE LINE is Next try would be adding this line as
// this headerInterceptor we have added .add("Connection","close")
// may be we need to remove the authorization from that headerInterceptor
.build();
return new Retrofit.Builder()

.addConverterFactory(GsonConverterFactory.create())

I need to pass a header when I try to show a image using Picasso.
Can any one suggest how to add header to picasso while viewing the image.
You can use downloader for that:
https://github.com/JakeWharton/picasso2-okhttp3-downloader
Example:
OkHttpClient client = new OkHttpClient.Builder()
.addInterceptor(new Interceptor() {
#Override
public Response intercept(Chain chain) throws IOException {
Request newRequest = chain.request().newBuilder()
.addHeader("custom-header", "custom-header-value")
.build();
return chain.proceed(newRequest);
}
})
.build();
Picasso picasso = new Picasso.Builder(context)
.downloader(new OkHttp3Downloader(client))
.build();
Keep in mind that if you are using OkHttpClient already, you should use that instance or create new one using client.newBuilder(). This way, both instances will be using the same request queue.
I am using multipart for uploading data to server. The problem is that the backend developer told me that the file I was uploading became corrupted during upload.
So is there any way to test those file locally? Like can I convert a file to multipart and then reconvert it to file to test it?
I am using Retrofit 2
Thanks
ask your backend developer whether he want file as binary or as base64 if it is image and then send file accordingly
you can also log what data is being sent in body of your post
here is code to log data you are sending through retrofit
public class RetrofitClient {
private RetrofitClient() {
}
public static Retrofit getApiClient(String baseHost) {
HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
// set your desired log level
logging.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
httpClient.addInterceptor(logging);
httpClient.addInterceptor(new Interceptor() {
#Override
public Response intercept(Interceptor.Chain chain) throws IOException {
Request original = chain.request();
// Request customization: add request headers
Request.Builder requestBuilder = original.newBuilder()
.header(Util.HEADER_KEY, ""+Util.HEADER_VALUE); // <-- this is the important line
Request request = requestBuilder.build();
return chain.proceed(request);
}
});
OkHttpClient client = httpClient.build();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(baseHost)
.addConverterFactory(new NullOnEmptyConverterFactory())
.addConverterFactory(GsonConverterFactory.create())
.client(httpClient.build())
.build();
return retrofit;
}
}
I'm just learning Retrofit and OKHttp, now I have an issue.
Every request in my app is POST, just like this:
#FormUrlEncoded
#POST("some url")
Observable<Result> getData(#Field("id") String id);
In every POST, there are two same params. So in a most simple way, I can add two more #Field in every method, for example, #Field("token"),#Field("account"). But I think there must be a smart way.
Then I thought OkHttpClient may solve this.
OkHttpClient client = new OkHttpClient.Builder().addInterceptor(new Interceptor() {
#Override
public Response intercept(Chain chain) throws IOException {
Request request = chain.request();
RequestBody body = new FormBody.Builder().add("account", "me")
.add("token", "123456").build();
request = request.newBuilder().post(body).build();
return chain.proceed(request);
}
}).build();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("some base url")
.client(client)
.addConverterFactory(GsonConverterFactory.create())
.addCallAdapterFactory(RxJavaCallAdapterFactory.create())
.build();
Or
HttpUrl url = request.url().newBuilder()
.setEncodedQueryParameter("account", "me")
.setEncodedQueryParameter("token", "123456")
.build();
The first method just replace all Field to these two.
The second method just add these two as GET parameters, not POST.
Now I have absolutely no idea how to make this work.
OK...Finally I find a way to do this. But I'm not sure this is the best way.
Here is the code:
OkHttpClient client = new OkHttpClient.Builder().addInterceptor(new Interceptor() {
#Override
public Response intercept(Chain chain) throws IOException {
Request request = chain.request();
FormBody.Builder bodyBuilder = new FormBody.Builder();
FormBody b = (FormBody) request.body();
for (int i=0;i<b.size();i++) {
bodyBuilder.addEncoded(b.name(i),b.value(i));
}
bodyBuilder.addEncoded("account", "me").add("token", "123456");
request = request.newBuilder().post(bodyBuilder.build()).build();
return chain.proceed(request);
}
}).build();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("http://some url)
.client(client)
.addConverterFactory(GsonConverterFactory.create())
.addCallAdapterFactory(RxJavaCallAdapterFactory.create())
.build();
I get all the #Field from retrofit, then add every key-value params to a new RequestBody, same as these two default params. Now every POST request has "account" and "token".
If there is a better way to do this, please let me know.
You can do that by adding a new request interceptor to the OkHttpClient. Intercept the actual request and get the HttpUrl. The http url is required to add query parameters since it will change the previously generated request url by appending the query parameter name and its value.
OkHttpClient.Builder httpClient =
new OkHttpClient.Builder();
httpClient.addInterceptor(new Interceptor() {
#Override
public Response intercept(Chain chain) throws IOException {
Request original = chain.request();
HttpUrl originalHttpUrl = original.url();
HttpUrl url = originalHttpUrl.newBuilder()
.addQueryParameter("apikey", "your-actual-api-key")
.build();
// Request customization: add request headers
Request.Builder requestBuilder = original.newBuilder()
.url(url);
Request request = requestBuilder.build();
return chain.proceed(request);
}
});
I'm trying to configure cache with Retrofit 1.9.0 and OkHtttp 2.5.0.
Here is how I provide OkHttpClient for my RestAdapter:
#Provides
#Singleton
public OkHttpClient provideOkHttpClient() {
OkHttpClient okHttpClient = new OkHttpClient();
okHttpClient.setConnectTimeout(TIMEOUT_IN_SECONDS, TimeUnit.SECONDS);
okHttpClient.setReadTimeout(TIMEOUT_IN_SECONDS, TimeUnit.SECONDS);
okHttpClient.setWriteTimeout(TIMEOUT_IN_SECONDS, TimeUnit.SECONDS);
File cacheDir = new File(context.getCacheDir(), "http");
final Cache cache = new Cache(cacheDir, DISK_CACHE_SIZE_IN_BYTES);
okHttpClient.setCache(cache);
okHttpClient.interceptors().add(new Interceptor() {
#Override
public Response intercept(Chain chain) throws IOException {
Response response = chain.proceed(request);
Response finalResponse = response.newBuilder()
.header("Cache-Control", String.format("public, max-stale=%d", 604800))
.build();
Log.d("OkHttp", finalResponse.toString());
Log.d("OkHttp Headers", finalResponse.headers().toString());
return finalResponse;
}
});
return okHttpClient;
}
I did not forget to setClient on RestAdapter.Builder. Also made sure, that I'm actually using instance of RestAdapter with this client set.
Even checked if the files are created under "http" folder. They are.
However after I turn of WIFI and reload my screen I end up in OnError callback of Observable endpoint with this message:
retrofit.RetrofitError: failed to connect to /10.40.31.12 (port 8888) after 10000ms: connect failed: ENETUNREACH (Network is unreachable)
DISCLAIMER: I should probably mention that the final Observable is combined from 5 others, with flatMap and zip on the way.
I think I have an answer. Short one is: "Cannot be done if server sends no-cache header in response".
If you want the longer one, details are below.
I've made a sample app comparing 2 backends. Lets call them Backend A, and Backend B. A was giving me troubles so I've decided to check on B.
A returns CacheControl = "no-cache, no-transform, max-age=0"
B returns Cache-Control = „public" response header
I did the same setup for both backends, just different urls.
private void buildApi() {
Gson gson = new GsonBuilder().create();
OkHttpClient okHttpClient = new OkHttpClient();
okHttpClient.setConnectTimeout(10, TimeUnit.SECONDS);
File cacheDir = new File(getCacheDir(), "http");
final Cache cache = new Cache(cacheDir, 1000000 * 10);
okHttpClient.setCache(cache);
okHttpClient.interceptors().add(new Interceptor() {
#Override
public Response intercept(Chain chain) throws IOException {
Request request = chain.request();
Log.d("OkHttp REQUEST", request.toString());
Log.d("OkHttp REQUEST Headers", request.headers().toString());
Response response = chain.proceed(request);
response = response.newBuilder()
.header("Cache-Control", String.format("public, max-age=%d, max-stale=%d", 60, RESPONSE_CACHE_LIFESPAN_IN_SECONDS))
.build();
Log.d("OkHttp RESPONSE", response.toString());
Log.d("OkHttp RESPONSE Headers", response.headers().toString());
return response;
}
});
RestAdapter.Builder builder = new RestAdapter.Builder()
.setConverter(new StringGsonConverter(gson))
.setClient(new OkClient(okHttpClient))
.setRequestInterceptor(new RequestInterceptor() {
#Override
public void intercept(RequestFacade request) {
if (isNetworkAvailable()) {
request.addHeader("Cache-Control", "public, max-age=" + 60);
} else {
request.addHeader("Cache-Control", "public, only-if-cached, max-stale=" + RESPONSE_CACHE_LIFESPAN_IN_SECONDS);
}
}
});
builder.setEndpoint("http://this.is.under.vpn.so.wont.work.anyway/api");
A_API = builder.build().create(AApi.class);
builder.setEndpoint("http://collector-prod-server.elasticbeanstalk.com/api");
B_API = builder.build().create(BApi.class);
}
Did both calls, then disabled wifi.
Cache worked fine for B, but A thrown 504 Unsatisfiable Request (only-if-cached)
It seems that overwritting headers won't help in that case.
You should rewrite your Request instead of the Response. For reference, see the docs on rewriting requests. Note you, can also use the CacheControl class instead of building your own header if you want. Your interceptor should look something like --
okHttpClient.interceptors().add(new Interceptor() {
#Override
public Response intercept(Chain chain) throws IOException {
Request request = chain.request();
Request cachedRequest = request.newBuilder()
.cacheControl(new CacheControl.Builder()
.maxStale(7, TimeUnit.DAYS)
.build())
.build();
return chain.proceed(cachedRequest);
}
});
