Android将图片上传到php服务器的实例代码

本文讲解"Android将图片上传到php服务器的实例代码"，希望能够解决相关问题。

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:

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);?>
