Volley-XUtils-OkHttp三种方式实现单张多张图片上传

OkHttp可以作为Volley底层传输协议，速度更快，传大量图片建议使用。OkHttp更多功能请看OkHttp的使用

xUtils 支持大文件上传，更全面的http请求协议支持(10种谓词)，拥有更加灵活的ORM，更多的事件注解支持且不受混淆影响...

xUtils一共有4大功能：注解模块，网络模块，图片加载模块，数据库模块。相关请看xUtils框架的使用博客

使用Volley上传，猪哟是继承volley的Request类，然后通过使用httpmim的MultipartEntity类对文件参数进行封装。

Volley更多功能请看Volley框架使用

所需的jar包：

httpclient-4.3.5.jar，android-async-http-1.4.4.jar

httpcore-4.3.2.jar，        httpmime-4.3.5

okhttp.jar，okio.jar，volley.jar，xUtils-2.6.2.jar

OkHttp代码：

private static final Handler handler = new Handler(Looper.getMainLooper());  

private static final MediaType MEDIA_TYPE_PNG = MediaType.parse("image/*");  

private static final OkHttpClient client = new OkHttpClient.Builder()
        .addInterceptor(new Interceptor() {
            @Override
            public Response intercept(Chain chain) throws IOException {
                okhttp3.Request request = chain.request().newBuilder()
                        .build();
                return chain.proceed(request);
            }
        }).readTimeout(15, TimeUnit.SECONDS)// 设置读取超时时间
        .writeTimeout(15, TimeUnit.SECONDS)// 设置写的超时时间
        .connectTimeout(15, TimeUnit.SECONDS)// 设置连接超时时间
        .build();  

// 上传图片公有方法
private final static void uploadImgAndParameter(Map<String, Object> map,
        String url) {  

    // mImgUrls为存放图片的url集合
    MultipartBody.Builder builder = new MultipartBody.Builder()
            .setType(MultipartBody.FORM);  

    if (null != map) {
        for (Map.Entry<String, Object> entry : map.entrySet()) {
            if (entry.getValue() != null) {
                if (entry.getValue() instanceof File) {
                    File f = (File) entry.getValue();
                    builder.addFormDataPart(entry.getKey(), f.getName(),
                            RequestBody.create(MEDIA_TYPE_PNG, f));
                } else {
                    builder.addFormDataPart(entry.getKey(), entry
                            .getValue().toString());
                }
            }  

        }
    }
    // 创建RequestBody
    RequestBody body = builder.build();
    final okhttp3.Request request = new okhttp3.Request.Builder().url(url)// 地址
            .post(body)// 添加请求体
            .build();
    client.newCall(request).enqueue(new okhttp3.Callback() {  

        @Override
        public void onResponse(Call call, final Response response)
                throws IOException {
            final String data = response.body().string();
            Log.i(TAG, "上传照片成功-->" + data);
            call.cancel();// 上传成功取消请求释放内存
        }  

        @Override
        public void onFailure(Call call, final IOException e) {
            Log.i(TAG, "上传失败-->" + e.getMessage());
            call.cancel();// 上传失败取消请求释放内存
        }  

    });  

} 

XUtils：

HttpUtils http = new HttpUtils();
        RequestParams params = new RequestParams();
        params.addBodyParameter("c", "comment");
        params.addBodyParameter("a", "add");
        params.addBodyParameter("uid", "1000191");
        params.addBodyParameter("dataid", "1114");
        params.addBodyParameter("message", "你好");
        params.addBodyParameter("datatype", "goodsid");
        for (int i = 0; i < 2; i++) {
            params.addBodyParameter("filedata" + i, file[i]);
        }
        http.send(HttpRequest.HttpMethod.POST, url, params,
                new RequestCallBack<String>() {  

                    @Override
                    public void onFailure(HttpException arg0, String arg1) {  

                    }  

                    @Override
                    public void onSuccess(ResponseInfo<String> arg0) {
                        Log.i(TAG, arg0.result.toString());
                    }  

                });  

Volley：

public static void addPutUploadFileRequest(final Map<String, File> files,
            final Map<String, String> params,
            final Listener<String> responseListener,
            final ErrorListener errorListener) {
        if (null == url || null == responseListener) {
            return;
        }  

        MultiPartStringRequest multiPartRequest = new MultiPartStringRequest(
                Request.Method.POST, url, responseListener, errorListener) {  

            @Override
            public Map<String, File> getFileUploads() {
                return files;
            }  

            @Override
            public Map<String, String> getStringUploads() {
                return params;
            }  

        };  

        mSingleQueue.add(multiPartRequest);
    }  

    Listener<JSONObject> mResonseListener = new Listener<JSONObject>() {  

        @Override
        public void onResponse(JSONObject response) {
            Log.i(TAG + "1", response.toString());
        }
    };  

    Listener<String> mResonseListenerString = new Listener<String>() {  

        @Override
        public void onResponse(String response) {
            Log.i(TAG + "2", response.toString());
        }
    };  

    ErrorListener mErrorListener = new ErrorListener() {  

        @Override
        public void onErrorResponse(VolleyError error) {
            if (error != null) {
                if (error.networkResponse != null)
                    Log.i(TAG + "3", " error "
                            + new String(error.networkResponse.data));
            }
        }
    };  

不要忘记在AndroidManifest.xml加权限哦！

 <uses-permissionandroid:name="android.permission.INTERNET"/>

 <uses-permissionandroid:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

本人测试全部成功了的
