Clide请求图片+OkHttp请求数据+图片上传和下载显示

首先得到展示上传头像和获取用户信息的接口：

把模拟器中的图片上传上去后并下载下来，在activity中显示：

首先需要的依赖：

compile 'com.squareup.okhttp3:okhttp:3.10.0'
implementation files('libs/gson-2.6.2.jar')
compile 'com.github.bumptech.glide:glide:3.7.0'

Activity_main.xml中：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context="com.example.zym.okhttpupfile.MainActivity">
    <Button
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="上传"
        android:onClick="upFile"/>
    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/image"/>
</LinearLayout>

MainActivity中：

            }
            @Override

                            //如果是成功的话，我就可以获得头像图片的地址


                            String json = response.body().string();

                            //获得用户的信息，并进行解析
                            UserBean userBean = new Gson().fromJson(json, UserBean.class);

                            final String iconURl = userBean.getData().getIcon();

                            //要放在主线程
                            runOnUiThread(new Runnable() {
