安卓图片的本地上传方法

Question

现在在写一个安卓本地图片上传，获取到了图片，也可以显示到界面，该怎么传到后台？

Answer 1

okhttp框架

//1、创建一个OkHttpClient
OkHttpClient client = new OkHttpClient();
//2、创建一个表单对象
//读取图片数据
Bitmap bitmap = BitmapFactory.decodeResource(getResources(),R.drawable.a5);
ByteArrayOutputStream bos = new ByteArrayOutputStream();
//将图片数据转换为byte数据
bitmap.compress(Bitmap.CompressFormat.JPEG,100,bos);
MultipartBody body = new MultipartBody.Builder()
.setType(MultipartBody.FORM)
//添加文本数据
.addFormDataPart("nikename","fengcheche05")
.addFormDataPart("username","fengcheche05")
.addFormDataPart("password","123456")
//添加文件数据
.addFormDataPart("portrait","abc.jpg",RequestBody.create(MediaType.parse("image/jpeg"),bos.to
ByteArray()))
.build();
//3、创建一个Requesta
Request request = new Request.Builder()
.url("http://139.129.19.51/story/index.php/home/Interface/regist")
.post(body)
.build();
//4、获得Call对象
Call call = client.newCall(request);
//5、执行请求，指定回调对象，该方法是异步执行，可以在主线程调用
call.enqueue(new Callback() {
@Override
public void onFailure(Call call, IOException e) {
//请求失败时调用该方法
Log.v(LOG_TAG,"请求失败!");
}
@Override
public void onResponse(Call call, Response response) throws IOException {
//请求成功时调用该方法
Log.v(LOG_TAG,"请求成功--->"+new String(response.body().bytes()));
}
});
