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:
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!
由于代码太多,完整代码未给出,源码直接下载即可
