Reflection call private method practice (php, java), _PHP tutorial
Practice of reflective calling private methods (php, java), There is a common problem in single testing, the private method in the side class cannot be called directly. During the processing, Xiaoyan changes the method permissions through reflection, conducts a single test, shares it, and directly uploads the code. Simple test class Generate a simple test class with only one private method. The code is as follows: <?php/** * Basic template for Cui Xiaohuan’s single test. * * @author cuihuan * @date 2015/11/12 22:15:31 * @version $Revision:1.0$ **/class MyClass {/** * Private method* * @param $params * @return bool */ private function privateFunc($params){if(!isset($params)){return false;}echo "test success";return $params;}} Unit test code The code is as follows: objMyClass = new MyClass();}/** * Use reflection to unit test the private and protect methods in the class* * @param $strMethodName string: Reflection function name* @return ReflectionMethod obj: callback object*/protected static function getPrivateMethod($strMethodName) {$objReflectClass = new ReflectionClass(self::CLASS_NAME);$method = $objReflectClass->getMethod($strMethodName);$method->setAccessible(true );return $method;}/** * @brief: Test the call of private function*/public function testPrivateFunc(){$testCase = ‘just a test string’;//Reflect this class $testFunc = self::getPrivateMethod( ‘privateFunc’);$res = $testFunc->invokeArgs($this->objMyClass, array($testCase));$this->assertEquals($testCase, $res);$this->expectOutputRegex(‘/success/ i’);//Catch no parameter exception test try { $testFunc->invokeArgs($this->transfer2Pscase, array());} catch (Exception $expected) {$this->assertNotNull($expected);return true ;}$this->fail(self::FAIL);}} Run results cuihuan:test cuixiaohuan$ phpunit…

PHP+iFrame implements asynchronous file upload without page refresh, _PHP tutorial
PHP+iFrame implements asynchronous file upload without page refresh, The example in this article describes PHP+iFrame’s implementation of asynchronous file upload without page refresh, which is a very practical and common technique. Share it with everyone for your reference. The specific analysis is as follows: Speaking of iframe, fewer and fewer people use it now, and many people believe that it should be replaced by AJAX. This is true, because AJAX is so good. However, there is one situation where I still choose iframe for implementation. This is the asynchronous upload of files that this article is about. If you are interested, you can try it. If you use native AJAX to implement it, it should be much more complicated. First, let’s provide beginners with basic knowledge: 1. The iframe tag usually specifies its name attribute for identification; 2. Determine the submission destination through action (target address) and target (target window, default is _self) in the form; 3. Point the target in the form to the name of the iframe, and the form can be submitted to the hidden frame iframe; 4. The content in the iframe is actually a page, and the parent object in js refers to the parent…

The paging function is a frequently used function, so it is encapsulated in the form of a function. //Paging and packaging /** * $pageType paging type 1 is digital paging 2 is text paging * You can pass $pageTotal, $page, $total and other data as parameters, or as global variables in paging (recommended) */ function paging($pageType) { global $pageTotal,$page,$total; if($pageType == 1) { echo ”; echo”; for($i=0; $i <$pageTotal; $i++) { if($page == ($i+1)) { echo ‘.($i+1).'” class=”selected”>’.($i+1). ”; } else { echo ‘.($i+1).'”>’.($i+1).’ ‘; } } echo”; echo”; } else if($pageType == 2) { echo ”; echo ”; echo ”.$page.’/’.$pageTotal.’page | ‘; echo ‘Total’.$total .’ members | ‘; //First page if($page == 1) { echo ‘Home | ‘; echo ‘Previous page | ‘; } else { // $_SERVER[“SCRIPT_NAME”] gets the current script name for easy transplantation //You can also customize constants, the constant values are consistent with the script file name echo ‘.$_SERVER[“SCRIPT_NAME”].'”>Home | ‘; echo ‘.$_SERVER[“SCRIPT_NAME”].’?page=’.($page – 1) .'”>Previous page| ‘; } //Last page if($page == $pageTotal) { echo ‘Next page | ‘; echo ‘Last page | ‘; } else { echo…
PHP runs under iis in fastCGI mode. File system permission problems encountered and solutions, _PHP tutorial
php runs under iis in fastCGI mode, and encountered file system permission problems and solutions. Today I am going to run a php demo under IIS. The website is in IIS The configuration below is like this: The application pool is .net framework 2.0 in integrated mode (2.0 or 4.0 does not matter, because PHP runs in fastCGI mode), and the application pool identifier is configured as IIS built-in NETWORKSERVICE, the authentication method used is Anonymous Authentication. When I opened the local website and accessed the php page, a 500 error occurred. Okay, it’s a permissions issue. The simplest solution is to set the permissions of C:\Users\Administrator\PhpstormProjects\phpDemo to Everyone, and allow full control: Revisited the php page and succeeded: The above method is simple enough, but it is also too unsafe. It is usually no problem to set up a local demo to do this, but when it is actually online, it will cause problems sooner or later. So reset it and give the read-only permissions in the directory to the NETWRORKSERVICE account and try again However, the problem is still not solved. When accessing, a 401 error occurs The error message includes the display that the logged-in user is…
