 interface  ApiManager
     @Multipart
    @POST("/member/upload/avatar")
    Call<String> uploadFile5(@Part("token")String token,@PartMap Map<String,RequestBody> photo);  

public void upload6() {
        File file = new File("/storage/emulated/0/image.jpg");

        Map<String, RequestBody> map = new HashMap<>();
        
        ／／head_image为服务器需要的字段，
        map.put("head_image" + "\"; filename=\"" + "image.jpg", RequestBody.create(MediaType.parse("image/jpg"), file));

        Call<String> call = apiManager.uploadFile5("useId", map);
        call.enqueue(new Callback<String>() {
            @Override
            public void onResponse(Call<String> call, Response<String> response) {
                Log.v("Upload", response.message());
            }

            @Override
            public void onFailure(Call<String> call, Throwable t) {
                Log.v("onFailure", t.toString());//java.net.SocketException: sendto failed: ECONNRESET (Connection reset by peer) ------此处报异常
            }
        });
    }
