volley でuseragentを設定
よくわかんにゃかったので、よんだ。
30 public class Volley {
....
35 /**
36 * Creates a default instance of the worker pool and calls {@link RequestQueue#start()} on it.
37 *
38 * @param context A {@link Context} to use for creating the cache dir.
39 * @param stack An {@link HttpStack} to use for the network, or null for default.
40 * @return A started {@link RequestQueue} instance.
41 */
42 public static RequestQueue newRequestQueue(Context context, HttpStack stack) {
43 File cacheDir = new File(context.getCacheDir(), DEFAULT_CACHE_DIR);
44
45 String userAgent = "volley/0";
46 try {
47 String packageName = context.getPackageName();
48 PackageInfo info = context.getPackageManager().getPackageInfo(packageName, 0);
49 userAgent = packageName + "/" + info.versionCode;
50 } catch (NameNotFoundException e) {
51 }
52
53 if (stack == null) {
54 if (Build.VERSION.SDK_INT >= 9) {
55 stack = new HurlStack();
56 } else {
57 // Prior to Gingerbread, HttpUrlConnection was unreliable.
58 // See: http://android-developers.blogspot.com/2011/09/androids-http-clients.html
59 stack = new HttpClientStack(AndroidHttpClient.newInstance(userAgent));
60 }
61 }
62
63 Network network = new BasicNetwork(stack);
64
65 RequestQueue queue = new RequestQueue(new DiskBasedCache(cacheDir), network);
66 queue.start();
67
68 return queue;
69 }
HttpStackがnullのとき、 volleyではapi level 9以上は HttpURLConnection, それ以外は Apache HttpClientを利用している。 api level 8でuser agentを利用するには自分でHttpStackを定義する必要がある。
HurlStackを読んでみる
46 /**
47 * An {@link HttpStack} based on {@link HttpURLConnection}.
48 */
49 public class HurlStack implements HttpStack {
...
87 @Override
88 public HttpResponse performRequest(Request<?> request, Map<String, String> additionalHeaders)
89 throws IOException, AuthFailureError {
90 String url = request.getUrl();
91 HashMap<String, String> map = new HashMap<String, String>();
92 map.putAll(request.getHeaders());
93 map.putAll(additionalHeaders);
...
102 HttpURLConnection connection = openConnection(parsedUrl, request);
103 for (String headerName : map.keySet()) {
104 connection.addRequestProperty(headerName, map.get(headerName));
105 }
...
125 return response;
126 }
user agentを設定しているのは以下の部分.
104 connection.addRequestProperty(headerName, map.get(headerName));
わたってきたヘッダの値を設定しているだけなので、Requestを以下のように利用する
Request request = new StringRequest(
Request.Method.GET,
"http://www.google.com",
new Response.Listener<String>() {
@Override
public void onResponse(String s) {
// handle response
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError volleyError) {
// handle error response
}
}) {
public Map<String, String> getHeaders() {
Map<String, String> headers = new HashMap<String, String>();
headers.put("User-Agent", "Mozilla/5.0 (Linux; U; Android 4.0.4; ja-jp; SC-06D Build/IMM76D) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30");
return headers;
}
};
