说明代码： -

1.get user id form shared preference

2.创建okhttps客户端

3检查文件是否为空

4.创建一个多部分来添加参数和数据

5.创建for循环附加参数

您通过传递相同的名称覆盖相同的文件，也将其更改为文件[]或传递为file1和file2

 for (int i = 0; i < file.length; i++) {
                    Log.d(TAG, "TaskAdd: File " + file[i]);
                    if (file[i].exists()) {
                        Log.d(TAG, "TaskAdd: "+i);
                        //body.addPart()
                        body.addFormDataPart("files["+i+"]", file[i].getName(), RequestBody.create(MediaType.parse("Image/*"), file[i]));

                        Log.d(TAG, "TaskAdd: "+ body.getClass().getName());
                    } else {
                        Log.d(TAG, "TaskAdd: No file found");
                    }
                }
