Xutils3网络请求的封装详解

封装了一个Xutil3的网络请求工具类，分享给大家，本人水平有限，不足之处欢迎指出。

使用前先配置xutils3：

1.gradle中添加

compile 'org.xutils:xutils:3.3.40'

2.自定义Application

/** * Created by Joe on 2016/9/25. */public class MyApp extends Application { @Override public void onCreate() { super.onCreate(); x.Ext.init(this); x.Ext.setDebug(BuildConfig.DEBUG); // 是否输出debug日志, 开启debug会影响性能. }}

3.清单文件application节点点添加

android:name=".activitys.MyApp"

上面三步走完接下来就可以使用了

先写一个单利类，话不多说上代码

private volatile static XutilsHttp instance; private Handler handler; private XutilsHttp(){ handler = new Handler(Looper.getMainLooper()); } /** * 单利模式 * @return */ public static XutilsHttp getInstance(){ if (instance == null){ synchronized (XutilsHttp.class){ if (instance == null){ instance = new XutilsHttp(); } } } return instance; }

写好接口

//接口回调 public interface XCallBack{ void onResponse(String result); void onFail(String result); } //下载的接口回调 public interface XDownLoadCallBack{ void onstart(); void onLoading(long total,long current,boolean isDownloading); void onSuccess(File result); void onFail(String result); void onFinished(); }

封装普通get请求

/** * 普通get请求 * @param url * @param maps * @param callback */ public void get(String url, Map<String,String> maps, final XCallBack callback){ RequestParams params = new RequestParams(url); if (null != maps && !maps.isEmpty()){ for (Map.Entry<String,String> entry : maps.entrySet()){ params.addQueryStringParameter(entry.getKey(),entry.getValue()); } } x.http().get(params, new Callback.CommonCallback<String>() { private boolean hasError = false; private String result = null; @Override public void onSuccess(String result) { if (result != null) { this.result = result; } } @Override public void onError(Throwable ex, boolean isOnCallback) { hasError = true; Toast.makeText(x.app(), ex.getMessage(), Toast.LENGTH_LONG).show(); } @Override public void onCancelled(CancelledException cex) { } @Override public void onFinished() { if (!hasError && result != null) { onSuccessResponse(result,callback); } } }); }

带缓存的get请求

/** * 带缓存数据的异步get请求 * @param url * @param maps * @param ifCache 是否缓存 * @param cacheTime 缓存存活时间 * @param callback */ public void getCache(String url,Map<String,String> maps,final boolean ifCache,long cacheTime,final XCallBack callback){ RequestParams params = new RequestParams(url); params.setCacheMaxAge(cacheTime); if (null != maps && maps.isEmpty()){ for (Map.Entry<String,String> entry : maps.entrySet()){ params.addQueryStringParameter(entry.getKey(),entry.getValue()); } } x.http().get(params, new Callback.CacheCallback<String>() { private boolean hasError = false; private String result = null; @Override public boolean onCache(String result) { if (ifCache && null != result){ this.result = result; } // true: 信任缓存数据, 不在发起网络请求; false不信任缓存数据. return ifCache; } @Override public void onSuccess(String result) { if (result != null) { this.result = result; } } @Override public void onError(Throwable ex, boolean isOnCallback) { hasError = true; Toast.makeText(x.app(), ex.getMessage(), Toast.LENGTH_LONG).show(); } @Override public void onCancelled(CancelledException cex) { } @Override public void onFinished() { if (!hasError && result != null) { onSuccessResponse(result,callback); } } }); }

普通post请求

/** * 异步post请求 * @param url * @param maps * @param callback */ public void post(String url, Map<String,String> maps, final XCallBack callback){ RequestParams params = new RequestParams(url); if (null != maps && !maps.isEmpty()){ for (Map.Entry<String,String> entry : maps.entrySet()){ params.addBodyParameter(entry.getKey(),entry.getValue()); } } x.http().post(params, new Callback.CommonCallback<String>() { private boolean hasError = false; private String result = null; @Override public void onSuccess(String result) { if (result != null) { this.result = result; } } @Override public void onError(Throwable ex, boolean isOnCallback) { hasError = true; onFailResponse(ex.getMessage(),callback); } @Override public void onCancelled(CancelledException cex) { } @Override public void onFinished() { if (!hasError && result != null) { onSuccessResponse(result,callback); } } }); }

带缓存的post请求

/** * 带缓存数据的异步post请求 * @param url * @param maps * @param ifCache 是否缓存 * @param cacheTime 缓存存活时间 * @param callback */ public void postCache(String url,Map<String,String> maps,final boolean ifCache,long cacheTime,final XCallBack callback){ RequestParams params = new RequestParams(url); params.setCacheMaxAge(cacheTime); if (null != maps && maps.isEmpty()){ for (Map.Entry<String,String> entry : maps.entrySet()){ params.addBodyParameter(entry.getKey(),entry.getValue()); } } x.http().get(params, new Callback.CacheCallback<String>() { private boolean hasError = false; private String result = null; @Override public boolean onCache(String result) { if (ifCache && null != result){ this.result = result; } // true: 信任缓存数据, 不在发起网络请求; false不信任缓存数据. return ifCache; } @Override public void onSuccess(String result) { if (result != null) { this.result = result; } } @Override public void onError(Throwable ex, boolean isOnCallback) { hasError = true; Toast.makeText(x.app(), ex.getMessage(), Toast.LENGTH_LONG).show(); } @Override public void onCancelled(CancelledException cex) { } @Override public void onFinished() { if (!hasError && result != null) { onSuccessResponse(result,callback); } } }); }

文件的下载

/** * 下载文件 * @param url * @param filePath * @param callback */ public void downFile(String url, String filePath, final XDownLoadCallBack callback){ RequestParams params = new RequestParams(url); params.setSaveFilePath(filePath); params.setAutoRename(true); x.http().get(params, new Callback.ProgressCallback<File>() { @Override public void onSuccess(final File result) { //下载完成会走该方法 handler.post(new Runnable() { @Override public void run() { if (callback!=null){ callback.onSuccess(result); } } }); } @Override public void onError(final Throwable ex, boolean isOnCallback) { handler.post(new Runnable() { @Override public void run() { if (null != callback){ callback.onFail(ex.getMessage()); } } }); } @Override public void onCancelled(CancelledException cex) { } @Override public void onFinished() { handler.post(new Runnable() { @Override public void run() { if (callback!=null){ callback.onFinished(); } } }); } //网络请求之前回调 @Override public void onWaiting() { } //网络请求开始的时候回调 @Override public void onStarted() { handler.post(new Runnable() { @Override public void run() { if (null != callback){ callback.onstart(); } } }); } //下载的时候不断回调的方法 @Override public void onLoading(final long total, final long current, final boolean isDownloading) { //当前进度和文件总大小 handler.post(new Runnable() { @Override public void run() { if (callback!=null){ callback.onLoading(total,current,isDownloading); } } }); } }); }

文件的上传

/** * 文件上传 * * @param url * @param maps * @param file * @param callback */ public void upLoadFile(String url, Map<String, String> maps, Map<String, File> file, final XCallBack callback) { RequestParams params = new RequestParams(url); if (maps != null && !maps.isEmpty()) { for (Map.Entry<String, String> entry : maps.entrySet()) { params.addBodyParameter(entry.getKey(), entry.getValue()); } } if (file != null) { for (Map.Entry<String, File> entry : file.entrySet()) { params.addBodyParameter(entry.getKey(), entry.getValue().getAbsoluteFile()); } } // 有上传文件时使用multipart表单, 否则上传原始文件流. params.setMultipart(true); x.http().post(params, new Callback.CommonCallback<String>() { @Override public void onSuccess(String result) { onSuccessResponse(result, callback); } @Override public void onError(Throwable ex, boolean isOnCallback) { } @Override public void onCancelled(CancelledException cex) { } @Override public void onFinished() { } }); }

上传Json字符串到服务器

/** * 上传Json串到服务器 * @param url * @param maps 将需要传的各个参数放在Map集合里面 */ public void upLoadJson(String url, Map<String, String> maps, final XCallBack callback){ JSONObject js_request = new JSONObject();//服务器需要传参的json对象 try { for (Map.Entry<String,String> entry : maps.entrySet()){ js_request.put(entry.getKey(),entry.getValue()); } } catch (JSONException e) { e.printStackTrace(); } RequestParams params = new RequestParams(url); params.setAsJsonContent(true); params.setBodyContent(js_request.toString()); x.http().post(params, new Callback.CommonCallback<String>() {//发起传参为json的post请求， // Callback.CacheCallback<String>的泛型为后台返回数据的类型， // 根据实际需求更改 private boolean hasError = false; private String result = null; @Override public void onSuccess(String result) { if (result != null) { this.result = result; } } @Override public void onError(Throwable ex, boolean isOnCallback) { ex.printStackTrace(); } @Override public void onCancelled(CancelledException cex) { } @Override public void onFinished() { if (!hasError && result != null && callback!=null) { onSuccessResponse(result,callback); } } }); }

使用案例：

下载调用：

XutilsHttp.getInstance().downFile(url, Utils.getSDPath() + "/" + "ShopBox_Guide_Video/" + Utils.getFileName(url), new XutilsHttp.XDownLoadCallBack() { @Override public void onstart() { showDialog(DIALOG_DOWNLOAD_PROGRESS); } @Override public void onLoading(long total, long current, boolean isDownloading) { //当前进度和文件总大小 mProgressDialog.setMax((int) total); mProgressDialog.setProgress((int) current); } @Override public void onSuccess(File result) { //下载完成会走该方法 playMedia(result.getPath()); } @Override public void onFail(String result) { Toast.makeText(MainActivity.this, result, Toast.LENGTH_SHORT).show(); } @Override public void onFinished() { dismissDialog(DIALOG_DOWNLOAD_PROGRESS); } });

带缓存get请求

XutilsHttp.getInstance().postCache(url, null, true, 60000, new XutilsHttp.XCallBack() { @Override public void onResponse(String result) { // 成功获取数据 } @Override public void onFail(String result) { Toast.makeText(MainActivity.this, result, Toast.LENGTH_SHORT).show(); } });

就是这么简单，不足之处请大家多多指点
