android-async-http-cachedAndroid 异步 HTTP 库
android-async-http （android-async-http-cached）是基于 Android Asynchronous HTTP Library (https://github.com/loopj/android-async-http) 实现。
1.增加响应数据本地缓存功能。
2.便于JSON-RPC,XML-RPC方式调用。
用法：
public class TestActivity extends Activity {
private static final int REQUEST_GET_ID = 0;
private static final int REQUEST_POST_ID = 1;
private static final int REQUEST_POST_JSON_ID = 2;
private static final int REQUEST_POST_XML_ID = 3;
private RequestManager mRequestManager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.mRequestManager = RequestManager
.getInstance(getApplicationContext());
get();
postParams();
postJSONObject();
postXML();
}
/**
* get by url
*/
private void get() {
this.mRequestManager
.get("http://app.shafa.com/api/push/download/52a093cf3bf55d361e000477?response-content-type=application%2fvnd.android.package-archive",
null, requestListener, true, REQUEST_GET_ID);
}
/**
* post by RequestParams
*/
private void postParams() {
final RequestParams params = new RequestParams();
params.put("key1", "value1");
params.put("key2", "value2");
this.mRequestManager.post("http://server.winfirm.net/memoServer",
params, requestListener, REQUEST_POST_ID);
}
/**
* post by JSONObject
*/
private void postJSONObject() {
final JSONObject json = new JSONObject();
try {
json.put("key1", "value1");
json.put("key2", "value2");
} catch (JSONException e) {
e.printStackTrace();
}
this.mRequestManager.post("http://server.winfirm.net/memoServer", json,
requestListener, REQUEST_POST_JSON_ID);
}
/**
* post by xml
*/
private void postXML() {
final String xml = "<?xml version=\"1.0\" encoding=\"utf-8\"?><key1>value1</key1><key2>value2</key2>";
this.mRequestManager.post("http://server.winfirm.net/memoServer", xml,
requestListener, REQUEST_POST_XML_ID);
}
/**
* request listener
*/
private RequestListener requestListener = new RequestListener() {
@Override
public void onStart() {
}
@Override
public void onCompleted(int statusCode, byte[] data,
String description, int actionId) {
try {
System.out.println(new String(data, "UTF-8"));
} catch (Exception e) {
e.printStackTrace();
}
if (REQUEST_GET_ID == actionId) {
if (RequestListener.OK == statusCode) {
// sucess
} else {
// handler error case
}
} else if (REQUEST_POST_ID == actionId) {
} else if (REQUEST_POST_JSON_ID == actionId) {
} else if (REQUEST_POST_XML_ID == actionId) {
}
}
@Override
public void onProgress(int bytesWritten, int totalSize, int actionId) {
System.out.println(bytesWritten + "/" + totalSize);
}
};
