安卓图片文字上传至服务器

这个是我自己封装的，你可以参考下。addFormDataPart(key, value)是添加普通post参数，addFormDataPart(key, fileName, RequestBody.create(MEDIA_TYPE, file))
是上传文件的


        MediaType MEDIA_TYPE = MediaType.parse("application/x-www-form-urlencoded; charset=utf-8");
        MultipartBody.Builder builder = new MultipartBody.Builder();
        for (String key : request.getParams().keySet()) {
            builder.addFormDataPart(key, request.getParams().get(key));
        }
        for (String key : request.getFiles().keySet()) {
            File file = request.getFiles().get(key);
            builder.addFormDataPart(key, file.getName(), RequestBody.create(MEDIA_TYPE, file));
        }
        Request ok = new Request.Builder().url(request.getUrl()).post(getBody(builder.build(), callBack)).build();
        send(request, ok, callBack);
