整理Android Asynchronous Http Client的使用
<dependency> <groupId>com.loopj.android</groupId> <artifactId>android-async-http</artifactId> <version>1.4.5</version> </dependency>导包:
import com.loopj.android.http.*;创建一个AsyncHttpClient 对象并发送一个请求:
client.get("http://www.google.com", new AsyncHttpResponseHandler() { @Override public void onStart() { // called before request is started } @Override public void onSuccess(int statusCode, Header[] headers, byte[] response) { // called when response HTTP status is "200 OK" } @Override public void onFailure(int statusCode, Header[] headers, byte[] errorResponse, Throwable e) { // called when response HTTP status is "4XX" (eg. 401, 403, 404) } @Override public void onRetry(int retryNo) { // called when request is retried } });
import com.loopj.android.http.*; public class TwitterRestClient { private static final String BASE_URL = "http://api.twitter.com/1/"; private static AsyncHttpClient client = new AsyncHttpClient(); public static void get(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) { client.get(getAbsoluteUrl(url), params, responseHandler); } public static void post(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) { client.post(getAbsoluteUrl(url), params, responseHandler); } private static String getAbsoluteUrl(String relativeUrl) { return BASE_URL + relativeUrl; } }
import org.json.*; import com.loopj.android.http.*; class TwitterRestClientUsage { public void getPublicTimeline() throws JSONException { TwitterRestClient.get("statuses/public_timeline.json", null, new JsonHttpResponseHandler() { @Override public void onSuccess(int statusCode, Header[] headers, JSONObject response) { // If the response is JSONObject instead of expected JSONArray } @Override public void onSuccess(int statusCode, Header[] headers, JSONArray timeline) { // Pull out the first event on the public timeline JSONObject firstEvent = timeline.get(0); String tweetText = firstEvent.getString("text"); // Do something with the response System.out.println(tweetText); } }); } }
PersistentCookieStore
,这个类是Apache
HttpClient CookieStore 接口的实现,它可以自动将cookies保存到SharedPreferences 。AsyncHttpClient myClient = new AsyncHttpClient();
PersistentCookieStore myCookieStore = new PersistentCookieStore(this); myClient.setCookieStore(myCookieStore);
BasicClientCookie newCookie = new BasicClientCookie("cookiesare", "awesome"); newCookie.setVersion(1); newCookie.setDomain("mydomain.com"); newCookie.setPath("/"); myCookieStore.addCookie(newCookie);
RequestParams params = new RequestParams(); params.put("key", "value"); params.put("more", "data");2.创建一个带有一对参数的RequestParams
RequestParams params = new RequestParams("single", "value");3.创建一个带有Map的RequestParams
HashMap<String, String> paramMap = new HashMap<String, String>(); paramMap.put("key", "value"); RequestParams params = new RequestParams(paramMap);详情请参考:RequestParams Javadoc
InputStream myInputStream = blah; RequestParams params = new RequestParams(); params.put("secret_passwords", myInputStream, "passwords.txt");2.File方式
File myFile = new File("/path/to/file.png"); RequestParams params = new RequestParams(); try { params.put("profile_picture", myFile); } catch(FileNotFoundException e) {}3.byte数组形式
byte[] myByteArray = blah; RequestParams params = new RequestParams(); params.put("soundtrack", new ByteArrayInputStream(myByteArray), "she-wolf.mp3");
AsyncHttpClient client = new AsyncHttpClient(); client.get("http://example.com/file.png", new FileAsyncHttpResponseHandler() { @Override public void onSuccess(int statusCode, Header[] headers, File response) { // Do something with the file `response` } });
AsyncHttpClient client = new AsyncHttpClient(); client.setBasicAuth("username","password/token"); client.get("http://example.com");
AsyncHttpClient client = new AsyncHttpClient(); client.setBasicAuth("username","password", new AuthScope("example.com", 80, AuthScope.ANY_REALM)); client.get("http://example.com");
