layout中很普通,就是两个button和一个ImageView

android:layout_width="match_parent"

android:layout_height="match_parent"

android:orientation="vertical"

>

android:id="@+id/test"

android:layout_width="368dp"

android:layout_height="wrap_content"

android:text="button1"

android:textAllCaps="false" />

android:id="@+id/test2"

android:layout_width="368dp"

android:layout_height="wrap_content"

android:text="button2"

android:textAllCaps="false"

/>

android:id="@+id/image"

android:layout_width="0dp"

android:layout_height="495dp"

/>

在主页面中给按钮添加事件:

package success.xiaoyu.okhttp3;

import android.graphics.Bitmap;

import android.graphics.BitmapFactory;

import android.os.Environment;

import android.os.Handler;

import android.os.Message;

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.util.Log;

import android.view.View;

import android.widget.Button;

import android.widget.ImageView;

import java.io.File;

import java.io.IOException;

import java.io.InputStream;

import java.util.concurrent.TimeUnit;

import okhttp3.Call;

import okhttp3.Callback;

import okhttp3.MediaType;

import okhttp3.MultipartBody;

import okhttp3.OkHttpClient;

import okhttp3.Request;

import okhttp3.RequestBody;

import okhttp3.Response;

public class MainActivity extends AppCompatActivity {

private Button button1,button2;

private ImageView imageView;

private Handler handler = new Handler(){

public void handleMessage(Message msg) {

Bitmap bitmap = (Bitmap)msg.obj;

imageView.setImageBitmap(bitmap);

//Toast.makeText(MainActivity.this, Environment.getExternalStorageDirectory()+"",Toast.LENGTH_LONG).show();

}

};

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.layout);

button1 = (Button)findViewById(R.id.test);

button2 = (Button)findViewById(R.id.test2);

imageView = (ImageView)findViewById(R.id.image);

button1.setOnClickListener(new View.OnClickListener() {//将服务器的图片读取到本地

public void onClick(View view) {

OkHttpClient okHttpClient = new OkHttpClient();

Request request = new Request.Builder()

.url("https://cache.yisu.com/upload/information/20200623/125/127052.png")

.build();

okHttpClient.newCall(request).enqueue(new Callback() {

public void onFailure(Call call, IOException e) {

}

public void onResponse(Call call, Response response) throws IOException {

InputStream inputStream = response.body().byteStream();

Bitmap bitmap = BitmapFactory.decodeStream(inputStream);

Message msg = new Message();

msg.obj = bitmap;

handler.sendMessage(msg);

}

});

}

});

button2.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View view) {

uploadMultiFile();

}

});

}

private void uploadMultiFile() {//将图片发送到服务器

final String url = "https://cache.yisu.com/upload/information/20200623/125/127064.jpg");

RequestBody fileBody = RequestBody.create(MediaType.parse("application/octet-stream"), file);

File file2 = new File( Environment.getExternalStorageDirectory()+"/storage/emulated/0/", "yyw.jpg");

RequestBody fileBody2 = RequestBody.create(MediaType.parse("application/octet-stream"), file2);

RequestBody requestBody = new MultipartBody.Builder()

.setType(MultipartBody.FORM)

.addFormDataPart("image1", "xy.jpg", fileBody)

.addFormDataPart("image2", "yyw.jpg", fileBody2)

.build();

Request request = new Request.Builder()

.url(url)

.post(requestBody)

.build();

final okhttp3.OkHttpClient.Builder httpBuilder = new OkHttpClient.Builder();

OkHttpClient okHttpClient = httpBuilder

//设置超时

.connectTimeout(10, TimeUnit.SECONDS)

.writeTimeout(15, TimeUnit.SECONDS)

.build();

okHttpClient.newCall(request).enqueue(new Callback() {

@Override

public void onFailure(Call call, IOException e) {

Log.e("aa", "uploadMultiFile() e=" + e);

}

@Override

public void onResponse(Call call, Response response) throws IOException {

Log.i("bb", "uploadMultiFile() response=" + response.body().string());

}

});

}

}

服务器端代码:

header('Content-type: application/json;charset=utf-8');

if(empty($_FILES)) die('{"status":0,"msg":"错误提交"}');

$dirPath = './img/';//设置文件保存的目录

if(!is_dir($dirPath)){

//目录不存在则创建目录

@mkdir($dirPath);

}

$count = count($_FILES);//所有文件数

if($count<1) die('{"status":0,"msg":"错误提交"}');//没有提交的文件

$success = $failure = 0;

foreach($_FILES as $key => $value){

//循环遍历数据

$tmp = $value['name'];//获取上传文件名

$tmpName = $value['tmp_name'];//临时文件路径

//上传的文件会被保存到php临时目录，调用函数将文件复制到指定目录

if(move_uploaded_file($tmpName,$dirPath.date('YmdHis').'_'.$tmp)){

$success++;

}else{

$failure++;

}

}

$arr['status'] = 1;

$arr['msg'] = '提交成功';

$arr['success'] = $success;

$arr['failure'] = $failure;

echo json_encode($arr);

?>
