3.今天的任务

写图片传输的接口

4.代码/截屏

private void scImage() {
        //1、创建请求体
        RequestBody requestBody = new MultipartBody.Builder()
                .setType(MultipartBody.FORM)//请求类型
                .addFormDataPart("name", "lisi")//参数1

                // 第一个参数传到服务器的字段名，第二个你自己的文件名，第三个MediaType.parse("*/*")数据类型，这个是所有类型的意思,file就是我们之前创建的全局file，里面是创建的图片
                .addFormDataPart("uploadfile", "uploadfile", RequestBody.create(MediaType.parse("*/*"), file))
                .build();
        //2、调用工具类上传图片以及参数
        HttpUtil.uploadFile("http://192.168.24.148:8080/FishClass/upload", requestBody, new Callback() {
