Question

基本上我试图发布用户选择到我服务器的图像并将其保存在那里。

PHP文件：

<?php
    require_once __DIR__ . '/includes/functions.php';
    require_once __DIR__ . '/includes/config.php';

    $image = $_POST["avatar"];
    $user_id = $_POST["user_id"];

    $files = glob('avatars/*.jpg');
    $name = count($files) + 1;

    $decodedImage = base64_decode($image);
    file_put_contents("avatars/" . $name . ".jpg", $decodedImage);
?>

的Android

private class UploadFileToServer extends AsyncTask<Bitmap, Void, Void> {
    @Override
    protected Void doInBackground(Bitmap... params) {
        Bitmap bitmap = params[0];
        ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, byteArrayOutputStream);
        byte[] byteArray = byteArrayOutputStream .toByteArray();

        String base64avatar = Base64.encodeToString(byteArray, Base64.DEFAULT);
        String dataString = "user_id=" + userID + "&avatar=" + base64avatar;

        try {
            URL url = new URL(URL_OMITTED);
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.setRequestMethod("POST");
            conn.setDoOutput(true);

            DataOutputStream os = new DataOutputStream(conn.getOutputStream());
            os.writeBytes(dataString);
            os.flush();
            os.close();

            Log.d("Response code",conn.getResponseCode() + "");

            conn.disconnect();

        } catch(IOException e) {
            e.printStackTrace();
        }
        return null;
    }
}

文件在服务器上创建，但不可读。当我将compressformat设置为PNG时，奇怪地创建了一个可读文件，但它的损坏使其大部分是黑色而不是上传的图像。

结果显示base64不是URL_SAFE。通过更改public function add() { $service = $this->Services->newEntity(); if ($this->request->is('post')) { $service = $this->Services->patchEntity($service, $this->request->data); if ($this->Services->save($service)) { // Last inserted service id $service_id = $service->id; $serviceTime = $this->Services->ServiceTimes->newEntity(); $serviceTime->service_id = $service_id; $serviceTime->start_time = $this->request->data['serviceTimes']['start_time']; $serviceTime->end_time = $this->request->data['serviceTimes']['end_time']; if ($this->Services->ServiceTimes->save($serviceTime)) { $this->Flash->success(__('The service has been saved.')); return $this->redirect(['action' => 'index']); } } else { $this->Flash->error(__('The service could not be saved. Please, try again.')); } } $this->set(compact('service')); $this->set('_serialize', ['service']); $this->viewBuilder()->theme('ThemeAdmin'); }并添加

    $('#ex_basic_1').intimidatetime({
        previewFormat: 'yyyy-MM-dd HH:mm:ss:l',
        format: "yyyy-MM-dd HH:mm:ss:l"
    })

到php文件解码URL_SAFE字符串。

我确定这可能不是这样做的，但它确实有效。
