Question

当我尝试转到/newmerman时遇到此错误。

错误：传入的参数必须是12个字节的单个字符串或24个十六进制字符的字符串在新的ObjectID（/Users/ediewoelfle/Developer/Mermanager/node_modules/bson/lib/bson/objectid.js:57:11）在app.get（/Users/ediewoelfle/Developer/Mermanager/app/routes/mermen_routes.js:25:27）在Layer.handle [作为handle_request]（/Users/ediewoelfle/Developer/Mermanager/node_modules/express/lib/router/layer.js:95:5）在下一个（/Users/ediewoelfle/Developer/Mermanager/node_modules/express/lib/router/route.js:137:13）在Route.dispatch（/Users/ediewoelfle/Developer/Mermanager/node_modules/express/lib/router/route.js:112:3）在Layer.handle [作为handle_request]（/Users/ediewoelfle/Developer/Mermanager/node_modules/express/lib/router/layer.js:95:5）在/Users/ediewoelfle/Developer/Mermanager/node_modules/express/lib/router/index.js:281:22 在param（/Users/ediewoelfle/Developer/Mermanager/node_modules/express/lib/router/index.js:354:14）在param（/Users/ediewoelfle/Developer/Mermanager/node_modules/express/lib/router/index.js:365:14）在Function.process_params（/Users/ediewoelfle/Developer/Mermanager/node_modules/express/lib/router/index.js:410:3）

这是我的 mermen_routes.js

// Create a merman
app.get('/newmerman', (req, res) =>
{
    res.render('newmerman')
});
app.post('/addmerman', (req, res) =>
{
  const merman = { name: req.body.name, location: req.body.location };
  db.collection('mermen').insert(merman, function(err, doc)
  {
    if (err)
    {
      res.send("There was a problem adding the merman to the kingdom.");
    }
    else
    {
      res.redirect('mermenlist')
    }
  });
});

还有我的newmerman的html表单。

<h1>Do you want to build a merman?</h1>
<form action="/addmerman" method="POST">
  <input type="text" placeholder="Ken" name="name" />
  <input type="text" placeholder="castle" name="location" />
  <button type="submit" value="Yes I want to build a merman."></button>
</form>

Node js中的GET路由的参数传递错误
