4.調(diào)用

HttpUtil.getInstance().get(new HttpUtil.Builder().url("user/token/init").params("key", "1").params("type", "4").callBackSuccess(new CallBackSuccess() {@Overridepublic void onSuccess(String json) {TopicResponse topicResponse = JsonUtil.fromJson(json, TopicResponse.class);tv.setText(topicResponse.data.id);}}));

?5.添加上傳圖片功能?HttpUtil.java文件中

private static final MediaType MEDIA_TYPE_PNG = MediaType.parse("image/png");public void uploadImages(List<String> selectedImages, String url) {// mImgUrls為存放圖片的url集合MultipartBody.Builder builder = new MultipartBody.Builder().setType(MultipartBody.FORM);for (int i = 0; i < selectedImages.size(); i++) {File f = new File(selectedImages.get(i));if (f != null) {builder.addFormDataPart("img" + i, f.getName(), RequestBody.create(MEDIA_TYPE_PNG, f));}}MultipartBody requestBody = builder.build();//構(gòu)建請求Request request = new Request.Builder().url(url)//地址.post(requestBody)//添加請求體 .build();okHttpClient.newCall(request).enqueue(new okhttp3.Callback() {@Overridepublic void onFailure(okhttp3.Call call, IOException e) {Log.wtf(TAG, "request " + call.request().url());Log.wtf(TAG, "上傳失敗:e.getLocalizedMessage() = " + e.getLocalizedMessage());}@Overridepublic void onResponse(okhttp3.Call call, okhttp3.Response response) throws IOException {Log.wtf(TAG, "request " + call.request().url());Log.wtf(TAG, "上傳照片成功：response = " + response.body().string());}});}

調(diào)用 ?
