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");Android Asynchronous Http Client--Android 开源的网络异步加载类,布布扣,bubuko.com
