How to set the (OAuth token) Authorization Header on an Android OKHTTPClient request

android, httpurlconnection, java, oauth

Solution

If you use the current version (2.0.0), you can add a header to a request:

Request request = new Request.Builder()
            .url("https://api.yourapi...")
            .header("ApiKey", "xxxxxxxx")
            .build();

Instead of using:

connection.setRequestMethod("GET");    
connection.setRequestProperty("ApiKey", "xxxxxxxx");

However, for the older versions (1.x), I think the implementation you use is the only way to achieve that. As their changelog mentions:

Version 2.0.0-RC1 2014-05-23

New Request and Response types, each with their own builder. There's also a RequestBody class to write the request body to the network and a ResponseBody to read the response body from the network. The standalone Headers class offers full access to the HTTP headers.

Problem

I'm able to set the Auth Header on normal `HTTPURLConnection` requests like this: ``` URL url = new URL(source); HttpURLConnection connection = this.client.open(url); connection.setRequestMethod("GET"); connection.setRequestProperty("Authorization", "Bearer " + token); ``` This is standard for HttpURLConnection. In the above code snippet `this.client` is an instance of Square's `OkHTTPClient` (here). I'm wondering if there is an `OkHTTP`-specific way of setting the Auth Header? I see the `OkAuthenticator` class but am not clear on how exactly to use it / it looks like it only handles authentication challenges. Thanks in advance for any pointers.
