1 建立okhttpClient

• 程式碼如下,上傳檔案設定超時時間30s

  OkHttpClient client = new OkHttpClient.Builder()
                        .writeTimeout(30, TimeUnit.SECONDS)
                        .build();

建立多檔案上傳的container

• 設定檔案傳輸的編碼與型別

```
 MediaType MutilPart_Form_Data = MediaType.parse("multipart/form-data; charset=utf-8"
 
);

• 為防止亂碼，為其它表單資料設定格式

   try {

                    RequestBody bodyParams = RequestBody.create(MutilPart_Form_Data, JSON.toJSONString(params));

• 建立requestBodyBuilder

    MultipartBody.Builder requestBodyBuilder = new MultipartBody.Builder()
                            .setType(MultipartBody.FORM
 
)
                            .addFormDataPart("keyVo", "", bodyParams);

• 新增批量檔案

 //迴圈新增檔案
                    for (int i = 0; i < pathList.size(); i++) {
                        File file = new File(pathList.get(i));
                        requestBodyBuilder.addFormDataPart("files", file.getName(), RequestBody.create(MutilPart_Form_Data, new
 
 File(pathList.get(i))));
                    }

• 建立requestBody並執行，返回結果

  RequestBody requestBody = requestBodyBuilder.build();
                    Request request = new Request.Builder()
                            .url(ConstBuild.BASE_URL + url)
                            .post(requestBody)
                            .build();
                             Response response = client.newCall(request).execute();
                             String responseStr=response.body().toString();
                             Log.w("result","返回結果"+responseStr);

完整程式碼如下

   /**
     * @param url
     * @param pathList
     * @throws Exception
     */
    public static void upLoadFiles(final String url, final String signPath, final Map<String, Object> params, final List<String> pathList, final MyCallBack<String> myCallBack) {
        x.task().run(new Runnable() {
            @Override
            public void run() {
                ToolLog.w("http", "url:\n" + url);
                ToolLog.w("http", "請求引數 params:\n" + params.toString());
                OkHttpClient client = new OkHttpClient.Builder()
                        .writeTimeout(30, TimeUnit.SECONDS)
                        .build();
                try {
                    MediaType MutilPart_Form_Data = MediaType.parse("multipart/form-data; charset=utf-8");
                    RequestBody bodyParams = RequestBody.create(MutilPart_Form_Data, JSON.toJSONString(params));
                    MultipartBody.Builder requestBodyBuilder = new MultipartBody.Builder()
                            .setType(MultipartBody.FORM)
                            .addFormDataPart("keyVo", "", bodyParams);
                    //迴圈新增檔案
                    for (int i = 0; i < pathList.size(); i++) {
                        File file = new File(pathList.get(i));
                        requestBodyBuilder.addFormDataPart("imgs", file.getName(), RequestBody.create(MutilPart_Form_Data, new File(pathList.get(i))));
                    }
                    RequestBody requestBody = requestBodyBuilder.build();
                    Request request = new Request.Builder()
                            .url( url)
                            .post(requestBody)
                            .build();
                    Response response = client.newCall(request).execute();
                    myCallBack.onSuccess(response.body().string());
                } catch (IOException e) {
                    e.printStackTrace();
                    myCallBack.onError(new UnknownServiceException("伺服器錯誤"), false);
                }
            }

        });
    }

• MyCallBack

只是一個回撥介面，大家可以自定義
