我正在尝试构建一个RESTful api，用于存储带有密码和电子邮件的用户以及带有评论和回复的产品。此时此刻我正在尝试从名为Products的数据库中获取一些数据，并且我想显示一个产品给出他的身份证明的信息，但我收到了：
无法获取/ api / productinfo /：56990ef287f61aa20fdf5288
这是server.js

// connect the api routes under /api/*
app.use('/api', apiRoutes);
module.exports = apiRoutes;
// Start the server
app.listen(port);
console.log('http://localhost:' + port);
和database.js
module.exports = {
'secret': 'di.ionio.gr',
'database': 'mongodb://localhost/firstapp'
};
和package.json
{
"name": "firstapp",
"main": "server.js",
"dependencies": {
"bcrypt": "^0.8.5",
"body-parser": "~1.9.2",
"express": "~4.9.8",

"mongoose": "~4.2.4",
"mongodb" : "~1.2.5",
"morgan": "~1.5.0",
"passport": "^0.3.0",
"passport-jwt": "^1.2.1"
}
}

只是一个疯狂的猜测，但不应该你的app.get请求使用_id，如果我没有误会，你试图根据它生成的ID获取mongo中的项目，而不是一个自定义的？

错误表示没有定义此类路由'/api/productinfo/:name'。
根据您的代码，您为路由apiRoutes定义'/api'中间件。这意味着您在apiRoutes上定义的所有路线都将以'/api'开头。例如，您可以制作＆＃39; GET＆＃39;请求'/api/memberinfo'。
在'/resources/productinfo/:name'中间件上定义apiRoutes路由，这意味着您的请求应转到'api/resources/productinfo/:name'。因此，您的请求应更改为：
/api/resources/productinfo/56990ef287f61aa20fdf5288
