这是固定代码：
class UploadfileFixture extends CakeTestFixture {
/**
* Fields
*
* @var array
*/
public $fields = array(
'id' => array('type' => 'integer', 'null' => false, 'default' => null, 'key' => 'primary'),
'data' => array('type' => 'binary', 'null' => false, 'default' => null),
'path' => array('type' => 'string', 'null' => false, 'default' => null, 'collate' => 'utf8_general_ci',
'charset' => 'utf8'),
...
正如您所看到的那样binary列BLOB data $file['data'] = @file_get_contents($uri);
...
$model_file->save($file);

答案 0 :(得分：1)
我认为您使用的是MySQL，这意味着您的BLOB类型列将仅限于
L + 2个字节，其中 L ＆lt; 2 16
<强> http://dev.mysql.com/doc/refman/5.7/en/storage-requirements.html#idm140456796731584
即64k，你的151k远远超过了。
默认情况下，CakePHPs灯具仅支持binary，无论如何都会映射到blob。但是，您可以添加自定义列定义，或通过Mysql::$columns属性修改现有列定义。你可以这样做，例如
应用/型号/数据源/数据库/ AppMysql.php
<?php
App::uses('Mysql', 'Model/Datasource/Database');
class AppMysql extends Mysql
{
public function __construct($config, $autoConnect)
{
$this->columns['mediumbinary'] = array('name' => 'mediumblob');
parent::__construct($config, $autoConnect);
}
}
应用/配置/ database.php中
public $test = array(
'datasource' => 'Database/AppMysql',
// ...
);
您的灯具
public $fields = array(
// ...
'data' => array('type' => 'mediumbinary', 'null' => false, 'default' => null),
// ...
);
例如在那个特定的灯具中，比如
public function init()
{
$source = ConnectionManager::getDataSource($this->useDbConfig);
$source->columns['mediumbinary'] = array('name' => 'mediumblob');
parent::init();
}
