    }         return true;     }126报错异常的代码就是上述代码段18行 if ($res->RetCode > 0) {这个RetCode我一直以为是请求接口返回参数，没有觉得他错误应该是其他的错误。【这里是思维的坑】然后留意了一下这个(8, 'Undefined prope...', '/www/wwwroot/ap...', 126, Array)有报错信息，但是不完整。想了也半天，忽然想起项目中大量使用了try catch然后尝试了一下果然报错信息完整了/**      * @param string $phoneNumbers      * @param string $templateId      * @param string $templateParams      * @return bool      *

false;         }         return true;     }打印日志[2022-03-18 10:58:26] local.DEBUG: 异常错误：Undefined property: stdClass::$RetCode提示未定义属性的错误。果然这个RetCode有问题。补充：在laravel9中使用try格式use Exception; use Illuminate\Support\Facades\Log; try{ } catch(Exception $e){ Log::debug('异常错误：'.$e->getMessage());     throw new \Exception('系统异常'); }

PHP错误和异常处理的学习 错误和异常处理的学习在某些编程语言(例如JAVA)在特定的情况下将自动抛出异常,但是在PHP中异常必须手动抛出。异常处理的概念利用try,Exception,throw写一个简单抛出并捕捉的异常try{ throw new \Exception('发生了不可描述的错误', '500'); }catch(\Exception $e){ echo 'Exception '.$e->getCode().' : '.$e->getMessage().'<br/>'.' in '.$e->getFile().' On Line '.$e->getLine(); }提示109行异常代码就是 throw new \Exception('发生了不可描述的错误', '500');简单解释一下try,Exception,throw一般是try{}代码块和catch(){}代码块配套使用，一个try{}代码块可以配合多个catch代码块捕捉不同类型的异常。有一点需要注意：当有多个catch代码块时，传递给每一个catch代码块的对象必须具有不同的类型，这样php才能找到具体是哪个catch代码块。throw关键字触发异常处理机制。他是一个语言结构而不是函数，所以必须要给他传一个值。throw new \Exception('message', code);这个类的构造函数需要两个参数：一个消息和一个错误代码。Exception类
