byte[]怎么转file发送到接口，请大佬指点

[兽兽]

接口的参数是，

{“upload”：图片1.jpg}

这类目前是发送byte的，但我希望是转成file再发，要怎么转化，

    public static  String sendFile(String url, byte[] file, String typeName){
        RequestBody fileBody = RequestBody.create(MediaType.parse("application/octet-stream"),file);
        MultipartBody body = new MultipartBody.Builder()
                .setType(FROM_DATA)
                .addFormDataPart(typeName,"2.png",fileBody)
                .build();
        Request request = new Request.Builder()
                .post(body)
                .url(url)
                .build();
        Response response = null;
        Call call = mOkHttpClient.newCall(request);
        try {
            response = call.execute();
            if (response.isSuccessful()) {
                return response.body().string();
            }
        } catch (Exception e) {
            System.out.println("POST文件失败"+e.getMessage());
        } finally {
            if (response != null) {
                response.close();
            }
        }
        return "http类-》post传输空文件";
    }

传File进来，转成byte[]

[兽兽]

说反了吧，我要的是byte[] 转成File new File(IMGPAHT+imgname)；是这样吗， 但是怎么指定 文件的参数 {“upload”：new File(IMGPAHT+imgname)}

你把需求重新说一下，不太清楚你要做什么。是要改请求还是改接口

自己已解决了，
