我已基于Alan的博客创建了一个测试Magento 2.0.2 REST Web服务:http : //alankent.me/2015/07/24/creating-a-new-rest-web-service-in-magento-2/
我正在使用Postman调用自定义Web服务并收到以下错误:
"message": "Class does not exist",
"code": -1,
"trace": "#0 P:\\wwwroot\\Magento202_com_loc\\Web\\vendor\\magento\\framework\\Webapi\\ServiceInputProcessor.php(128): ReflectionClass->__construct('')\n#1 P:\\wwwroot\\Magento202_com_loc\\Web\\vendor\\magento\\framework\\Webapi\\ServiceInputProcessor.php(262): Magento\\Framework\\Webapi\\ServiceInputProcessor->_createFromArray(NULL, '30')\n#2 P:\\wwwroot\\Magento202_com_loc\\Web\\vendor\\magento\\framework\\Webapi\\ServiceInputProcessor.php(99): Magento\\Framework\\Webapi\\ServiceInputProcessor->convertValue('30', NULL)\n#3 P:\\wwwroot\\Magento202_com_loc\\Web\\vendor\\magento\\module-webapi\\Controller\\Rest.php(262): Magento\\Framework\\Webapi\\ServiceInputProcessor->process('Test\\\\Calculator...', 'add', Array)\n#4 P:\\wwwroot\\Magento202_com_loc\\Web\\vendor\\magento\\module-webapi\\Controller\\Rest.php(160): Magento\\Webapi\\Controller\\Rest->processApiRequest()\n#5 P:\\wwwroot\\Magento202_com_loc\\Web\\var\\generation\\Magento\\Webapi\\Controller\\Rest\\Interceptor.php(24): Magento\\Webapi\\Controller\\Rest->dispatch(Object(Magento\\Framework\\App\\Request\\Http))\n#6 P:\\wwwroot\\Magento202_com_loc\\Web\\vendor\\magento\\framework\\App\\Http.php(115): Magento\\Webapi\\Controller\\Rest\\Interceptor->dispatch(Object(Magento\\Framework\\App\\Request\\Http))\n#7 P:\\wwwroot\\Magento202_com_loc\\Web\\vendor\\magento\\framework\\App\\Bootstrap.php(258): Magento\\Framework\\App\\Http->launch()\n#8 P:\\wwwroot\\Magento202_com_loc\\Web\\index.php(39): Magento\\Framework\\App\\Bootstrap->run(Object(Magento\\Framework\\App\\Http))\n#9 {main}"
我可以成功地调用Magento的现成的REST Web服务。
