Change Redirect Policy of Volley Framework

I am using the Volley framework in a project where I always need to handle the redirects myself to handle the headers.

How redirects are handled depends right now on the method and the transport layer. I would like to use the defaults of Volley (automatic selection of the transport layer) without changing any Volley code.

A valid solution is to always use OkHttp as a transport layer (as mentioned in Issues and contribution for Volley), but I would like to know if there is a way without an additional framework.

Therefore I am looking for a "clean" way to disable automatic redirect handling.

Edit:

I prefer to use OkHttp so that I don't have to manage what version to use on what Android myself, but the solution provided by Itai Hanski is very good to, when wanting to change the transport layer behavior.

I think A HttpStack implementation for Volley that uses OkHttp as its transport is the best solution

RequestQueue queue = Volley.newRequestQueue(this);

Network network = new BasicNetwork(new OkHttpStack());
RequestQueue queue = new RequestQueue(new DiskBasedCache(new File(getCacheDir(), "volley")), network);
queue.start();

OkHttpStack class:

public class OkHttpStack extends HurlStack {
private final OkHttpClient client;

public OkHttpStack() {
this(new OkHttpClient());
}

public OkHttpStack(OkHttpClient client) {
if (client == null) {
throw new NullPointerException("Client must not be null.");
}
this.client = client;
}

@Override protected HttpURLConnection createConnection(URL url) throws IOException {
return client.open(url);
}
}

Update: if you are using new version of okhttp stack then use

public class OkHttpStack extends HurlStack {
    private final OkUrlFactory mFactory;

    public OkHttpStack() {
        this(new OkHttpClient());
    }

    public OkHttpStack(OkHttpClient client) {
        if (client == null) {
            throw new NullPointerException("Client must not be null.");
        }
        mFactory = new OkUrlFactory(client);
    }

    @Override
    protected HttpURLConnection createConnection(URL url) throws IOException {
       return mFactory.open(url);
    }
}

如果你不关心旧的API（<9），并且你只想在重定向之后停下来，你可以做

RequestQueue requestQueue = Volley.newRequestQueue(context, new HurlStack() {
    @Override
    protected HttpURLConnection createConnection(URL url) throws IOException {
        HttpURLConnection connection = super.createConnection(url);
        connection.setInstanceFollowRedirects(false);

        return connection;
    }
});

---

This solution doesn't require another framework:

Volley uses AndroidHTTPClient or Apache (if SDK level is 8 and under) by default. You could override / inherit the changes you want for redirection in these classes and create a custom HttpStack with them, feeding it to the Volley.newRequestQueue() .

EDIT:

Assuming the very long named custom HttpStack implementations are yours:

HttpStack stack;
if (Build.VERSION.SDK_INT >= 9) {
    stack = new RedirectionHurlStack();
} else {
    stack = new RedirectionHttpClientStack();
}

sRequestQueue = Volley.newRequestQueue(context, stack);
