405方法不允许使用带有Restify和CORS的DELETE

问题描述：

这主要是为了在本地开发服务。405方法不允许使用带有Restify和CORS的DELETE

我收到一个405 method not allowed DELETE请求使用Restify和CORS。我想我必须忽略一些东西。真的会感激一些新鲜的眼睛指出我做错了什么。

我知道restify-cors-middleware，但我没有使用它，因为它没有很好的记录，我也没有能够正确配置它。

相反，我已经为Restify实现了我自己的CORS配置。它适用于GET和POST，但不适用于DELETE。

// allows localhost to work 
if (process.env.DEV === 'true') { 
    app.pre((req, res, next) => { 
    res.header('Access-Control-Allow-Origin', '*'); 
    res.header('Access-Control-Allow-Headers', 'Accept, Authorization, Content-Type, Content-Disposition, Origin, X-Requested-With'); 
    res.header('Access-Control-Allow-Credentials', 'true'); 
    res.header('Access-Control-Allow-Methods', 'DELETE, GET, POST, OPTIONS, PUT'); 
    res.header('access-control-max-age', 86400); 

    return next(); 
    }); 

    app.opts('/.*/', (req, res, next) => { 
    res.send(200); 
    return next(); 
    }); 
}

答

看来好像你尚未为您的DELETE方法注册处理程序。响应显示了这个：

允许：OPTIONS

也许你没有正确连接了处理器？
