Question

我遇到的问题是我正确获取项目ID但是当调用delete方法时它只返回404错误。以下是使用的代码：前端

<% for(var i=0; i<projects.length; i++) {%>
              <tr>

                <td>  <%= projects[i].projectName %> </td>
                <td>  <%= projects[i].engineer %> </td>
                <td>  <%= projects[i].finalCost %> </td>
                <td>  <%= projects[i].status %>  </td>
                <td>

                  <button type="button" class="btn btn-outline-warning">Edit</button>
                  <form method="post" action="/delete/<%=projects[i]._id%>">
                    <button type="submit" name="delete" class="btn btn-outline-danger">Delete</button>
                    <input type="hidden" name="_method" value="DELETE" />
                  </form>
                </td>
              </tr>
                 <%}%>

后端：

app.delete('/delete/:_id', function(req, res, next){
  console.log(req.params._id);
var project = {_id: req.params._id};
db.collection('projects').remove({_id: project},(err, result) => {
  if (err) return console.log(err)

  console.log('deleted from database')
  res.redirect('/profile')
})
});

第1步删除ejs文件中的表单并添加<a href="/delete/<%=projects[i]._id%>"<a>

步骤2使用app.get

更改app.delete

Node.js＆amp; EJS 404调用delete方法时出错
