如何利用php 的exec执行nodejs文件? 如下执行却执行失败
<code> public function execTask ($dirPath) { $serverPath = self::$serverPath; exec("node httpd.js $serverPath",$info, $val); var_dump($info); echo "$val"; } </code>
如果仅仅是exec("node -v $serverPath",$info, $val);
却可以输出版本号,执行成功。求解答,谢谢。

你可以换成 shell_exec 试试
我也有类似的用法,所以除了有能读出消息的之外,还有能直接后台执行的功能,都是通过进程实现的
<code>/** * 返回的汉语文字信息在windows中是GB2312编码,需要手动改成UTF8 * iconv("GB2312","UTF-8",$read); * @param $cmd * @return array */ public function execFront($cmd) { $response = array(); $handle = popen("$cmd 2>&1", 'r'); while ($read = fread($handle, 20096)) { if(!mb_detect_encoding($read, 'UTF-8', true)) iconv("GB2312","UTF-8",$read); $response[] = trim($read); } pclose($handle); flush(); return $response; } /** * @param $cmd */ public function execBackend($cmd) { if (substr(php_uname(), 0, 7) == "Windows"){ pclose(popen("start cmd /c ". $cmd, "r")); } else { exec($cmd . " > /dev/null &"); } return; } </code>

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
