Android 一个参数多个文件上传

以上是我的上传接口需求刚开始我就用了Xutils框架传声音和多个图

params.addBodyParameter("voice", new File(audioPath1));

容我BB下

这里点进去可以看到它是Map集合添加参数的多个图片的 Map的key是唯一的上传的话只有最后一个在Map容器里所以这个方案不成立

然后尝试每个图片独立上传，结果服务器那边还是看到只有一个图片资源这个不知道什么原因后台的是个一直逼逼说就这样，没办法后台是大爷我换方式

再后来尝试用原生方法上传

HttpURLConnection

conn.setRequestMethod("POST");conn.setRequestProperty("connection", "keep-alive");conn.setRequestProperty("Charset", "UTF-8");conn.setRequestProperty("Content-Type", MULTIPART_FROM_DATA + ";boundary=" + BOUNDARY);// 拼接文本类型的参数StringBuilder textSb = new StringBuilder();if (textParams != null) {    for (Map.Entry<String, String> entry : textParams.entrySet()) {        textSb.append(PREFIX).append(BOUNDARY).append(LINE_END);        textSb.append("Content-Disposition: form-data; name=\"" + entry.getKey() + "\"" + LINE_END);        textSb.append("Content-Type: text/plain; charset=" + CHARSET + LINE_END);        textSb.append("Content-Transfer-Encoding: 8bit" + LINE_END);        textSb.append(LINE_END);

代码写出来是对的能跟服务器对接但是差后台数据库竟然没有抓取到声音、图片数据 ----白做原因是上面的方式有好多字段需要拼接的也不知道拼什么放弃了

再接着还用了OKHttp框架这个框架查资料的时候我看到了希望集成到项目完成时很激动结果运行一下报个什么过时错误还有个找不到什么类失望

重点：项目用了 libs/volly-1.0.11.jar

创建一个类

使用方法

/** * 上传 * @param url 地址 * @param audioPath 声音文件地址 * @param troubleId id */private void upload(String url, String audioPath, String troubleId) {    final RequestQueue requestQueue = Volley.newRequestQueue(mContext);    Map<String, String> map = HttpRequstPost.newMap();    map.put("troubleId", troubleId);    List<File> list = new ArrayList<>();    for (String img : listPath) { //图片集合        list.add(new File(img));    }    MultipartRequest.addSoundFile("voice", new File(audioPath));    MultipartRequest multipartRequest = new MultipartRequest(url, new Response.ErrorListener() {        @Override        public void onErrorResponse(VolleyError volleyError) {            Toast.makeText(getContext(), volleyError.getMessage(), Toast.LENGTH_SHORT).show();        }    }, new Response.Listener<String>() {        @Override        public void onResponse(String s) {            Toast.makeText(mContext, s, Toast.LENGTH_SHORT).show();        }    }, "picture", list, map);    requestQueue.add(multipartRequest);}
