layout中很普通,就是两个button和一个ImageView
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <Button android:id="@+id/test" android:layout_width="368dp" android:layout_height="wrap_content" android:text="button1" android:textAllCaps="false" /> <Button android:id="@+id/test2" android:layout_width="368dp" android:layout_height="wrap_content" android:text="button2" android:textAllCaps="false" /> <ImageView android:id="@+id/image" android:layout_width="0dp" android:layout_height="495dp" /> </LinearLayout>
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:
<?php 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); ?>
总结
