使用 php (yii2) 从本地计算机上传图像到 cloudinary 服务器

Question

我正在使用 yii2 框架让网站通过 API 上传到 Cloudinary。但出于某种原因，API 函数需要文件路径才能进行上传。

web 文件夹中的文件可以上传，但我不想上传到我的服务器而不是将它发送到 cloudinary 服务器（操作太多），我想从我的本地主机直接上传到 cloudinary 服务器

来自 yii2 控制器的上传代码：

    public function actionCreate()
    {
        $model = new Galerias();

        // inicializar o cloudinary
        $config = Configuration::instance();
        $config->cloud->cloudName = 'cloudName';
        $config->cloud->apiKey = 'yayaiknow';
        $config->cloud->apiSecret = 'gogogodude';
        $config->url->secure = true;

        // esta a ser feito o upload
        if ($model->load(Yii::$app->request->post())) {
            $data2 = date('Y-m-d h:m:s');
            if($model->validate()) {
                $image = UploadedFile::getInstance($model, 'image');
                // maybe remove this if to get URL of image from callback
                if((new UploadApi())->upload($image)){
                    $data = date('Y-m-d h:m:s');
                    $model->created_at = $data;
                    $model->updated_at = null;
                    if($model->save()){
                        return $this->redirect(['view', 'id' => $model->id]);
                    }
                }
            }
        }

        return $this->render('create', [
            'model' => $model,
        ]);

    }

表格代码：

<div class="galerias-form">
    <p>Imagem (tipo PNG-8) para: </p>
    <?php $form = ActiveForm::begin(['options' => ['enctype' => 'multipart/form-data']]); ?>

    <?= $form->field($model, 'image')->fileInput()->label('Monitores "Dimensão recomendado: 1920x1080px"'); ?>

    <?= $form->field($model, 'descricao')->textInput(['maxlength' => true]) ?>

    <?= $form->field($model, 'local')->radioList(array(0=>'Destaque',1=>'Fundo')); ?>

    <div class="form-group">
        <?= Html::submitButton('Guardar', ['class' => 'btn btn-success']) ?>
    </div>

    <?php ActiveForm::end(); ?>

</div>

当我尝试上传时（砰的一声）我收到了这个错误：

Cloudinary\Api\Exception\BadRequest
Unsupported source URL: a.jpg

我试图获取文件的原始相对（或绝对）路径，但没有成功。

一个有效的解决方案是将文件上传到我的网站服务器，到达那里并将其发送到 Cloudinary 服务器，最后从网站服务器中删除该图像。（步骤太多）

我需要帮助使其变得简单，上传文件并将其发送到 Cloudinary 并在回调中获取 URL 位置并将其保存在数据库中。

您应该传递您正在传递 Cloudinary 上传未知的 UploadedFiles 对象的文件路径 api。

您应该通过 $image->tempName 将路径传递到 (new UploadApi())->upload()，如下所示

(new UploadApi())->upload($image->tempName)

还有方法returns文件上传的响应，示例如下

Array
(
  [public_id] => c87hg9xfxrd4itiim3t0
  [version] => 1571218607
  [signature] => f8645b000be7d717599affc89a068157e4748276
  [width] => 864
  [height] => 576
  [format] => jpg
  [resource_type] => image
  [created_at] => 2017-06-23T13:59:18Z
  [bytes] => 120253
  [type] => upload
  [url] => http://res.cloudinary.com/demo/image/upload/v1571218607/c87hg9xfxrd4itiim3t0.jpg
  [secure_url] => https://res.cloudinary.com/demo/image/upload/v1571218607/c87hg9xfxrd4itiim3t0.jpg
)

或者出错时抛出异常，你应该改用 try catch 块。

try{
    (new UploadApi())->upload($image->tempName);
}catch(\Exception $e){
   Yii::$app->session->setflash('error',$e->getMessage());
}

你的完整动作应该是这样的

public function actionCreate()
{
    $model = new Galerias();

    // inicializar o cloudinary
    $config = Configuration::instance();
    $config->cloud->cloudName = 'cloudName';
    $config->cloud->apiKey = 'yayaiknow';
    $config->cloud->apiSecret = 'gogogodude';
    $config->url->secure = true;

    // esta a ser feito o upload
    if ($model->load(Yii::$app->request->post())) {
        $data2 = date('Y-m-d h:m:s');
        if ($model->validate()) {
            $image = UploadedFile::getInstance($model, 'image');
            // maybe remove this if to get URL of image from callback
            try {
                $response = (new UploadApi())->upload($image->tempName);
                $data = date('Y-m-d h:m:s');
                $model->created_at = $data;
                $model->updated_at = null;
                if ($model->save()) {
                    return $this->redirect(['view', 'id' => $model->id]);
                }
            } catch (\Exception $e) {
                Yii::$app->session->setFlash('error', $e->getMessage());
            }
        }
    }

    return $this->render('create', [
        'model' => $model,
    ]);

}
