1、简介

dazzle.common.http是一个Android访问网络的http工具。其中主要有：get方法请求、post方法请求、文件下载、文件上传等功能。主要是封装了HttpClient。参考框架，Afinal

2、get方法请求使用

/**
 * 异步GET测试
 * 
 * @param textView
 */
public static void getTest(final TextView textView) {
    HttpUtils httpUtils = new HttpUtils();
    RequestParams requestParams = new RequestParams(new Object[] { "name", "xuan", "age", "7" });
    httpUtils.get("http://192.168.0.103/test/test.htm", requestParams, new RequestCallBack<String>() {
        @Override
        public void onSuccess(String t) {
            textView.setText(t);
        }
    });
}

/**
 * 同步GET测试，耗时操作，要配合线程使用
 * 
 * @return
 */
public static void getSyncTest(final TextView textView) {
    HttpUtils httpUtils = new HttpUtils();
    RequestParams requestParams = new RequestParams();
    requestParams.put("name", "xuan");
    requestParams.put("age", "7");
    textView.setText((String) httpUtils.getSync("http://192.168.0.103/test/test.htm", requestParams));
}

3、post方法请求使用

/**
 * 同步POST测试，耗时操作，要配合线程使用
 * 
 * @return
 */
public static void postSyncTest(final TextView textView) {
    HttpUtils httpUtils = new HttpUtils();

    HashMap<String, String> paramMap = new HashMap<String, String>();
    paramMap.put("name", "xuan");
    paramMap.put("age", "7");

    RequestParams requestParams = new RequestParams(paramMap);

    textView.setText((String) httpUtils.postSync("http://192.168.0.103/test/test.htm", requestParams));
}

/**
 * 异步POST测试
 * 
 * @param textView
 */
public static void postTest(final TextView textView) {
    HttpUtils httpUtils = new HttpUtils();

    RequestParams requestParams = new RequestParams("name", "xuan");
    requestParams.put("age", "7");

    httpUtils.post("http://192.168.0.103/test/test.htm", requestParams, new RequestCallBack<String>() {
        @Override
        public void onSuccess(String t) {
            textView.setText(t);
        }
    });
}

3、下载文件API使用

public static void downloadTest(final TextView textView) {
    String target = Environment.getExternalStorageDirectory().getPath() + "/xuan/1.jpg";// 文件存放位置

    RequestCallBack<File> requestCallBack = new RequestCallBack<File>() {
        @Override
        public void onStart() {
            textView.setText("文件开始下载");
        }

        @Override
        public void onLoading(long count, long current) {
            textView.setText("文件下载进度：" + current + "/" + count);
        }

        @Override
        public void onSuccess(File t) {
            textView.setText("文件下载成功");
        }

        @Override
        public void onFailure(Throwable t, int errorNo, String strMsg) {
            textView.setText("文件下失败:Throwable[" + t.getMessage() + "]errorNo[" + errorNo + "]strMsg[" + strMsg
                    + "]");
        }
    };

    // 大大的注意，只有设置了这个方法，onLoading才会被调用有效，单位ms
    requestCallBack.progress(true, 10);

    HttpUtils httpUtils = new HttpUtils();
    httpUtils
            .download(
                    "http://h.hiphotos.baidu.com/album/w%3D2048/sign=bcc2b1908601a18bf0eb154faa170608/42166d224f4a20a471350b7b91529822720ed066.jpg",
                    target, requestCallBack);
}

4、上传文件API使用

public static void uploadFileTest(final TextView textView) {
    File file = new File(Environment.getExternalStorageDirectory().getPath() + "/xuan/1.jpg");
    RequestParams requestParams = new RequestParams();

    requestParams.put("name", "xuan");// 普通参数
    try {
        requestParams.put("file", file);// 文件参数
    }
    catch (Exception e) {
        textView.setText("文件不存在");
    }

    RequestCallBack<String> requestCallBack = new RequestCallBack<String>() {
        @Override
        public void onStart() {
            textView.setText("文件开始上传");
        }

        @Override
        public void onLoading(long count, long current) {
            textView.setText("文件上传进度：" + current + "/" + count);
        }

        @Override
        public void onSuccess(String t) {
            textView.setText(t);
        }

        @Override
        public void onFailure(Throwable t, int errorNo, String strMsg) {
            textView.setText("文件上传失败:Throwable[" + t.getMessage() + "]errorNo[" + errorNo + "]strMsg[" + strMsg
                    + "]");
        }
    };
    requestCallBack.progress(true, 10);

    HttpUtils httpUtils = new HttpUtils();
    httpUtils.post("http://192.168.0.103/test/test.htm", requestParams, requestCallBack);
}

5、结尾

轮子常有，好轮子也很多，自己造的，分外稀罕。
