放入和删除方法在postman中显示404

Question

0 I have been banging my head the long hours trying to figure why my PUT and DELETE request does not work. It returns a 404 not found response. My POST and GET all work fine.

I use chrome postman

app.put('api/courses/:id', (req, res) => {

    const course = courses.find(c => c.id === parseInt(req.params.id));
    if (!course) return res.status(404).send('This course with the given id was not found');

    const { error } = validateCourse(req.body);
    if (error) 
        return res.status(400).send(error.details[0].message);

    course.name = req.body.name;
    res.send(course);

});

app.delete('api/courses/:id', (req, res) => {
    const course = courses.find(c => c.id === parseInt(req.params.id));
    if (!course) return res.status(404).send('this course with the given ID is not valid');
  
    const index = courses.indexOf(course);
    courses.splice(index, 1)

    res.send(course);

})

function validateCourse(course) {
    const schema = {
        name: Joi.string().min(3).required()
    };

    return Joi.validate(course, schema);

}

I am trying to create a simple api in Node.js. The http method is not working

Add a leading / to the route definitions:

app.put('/api/courses/:id', ...);

There is no such thing as relative routes on the server.
