Question

我正在使用Express创建一个端点，以根据电影ID返回评论或从电影中查看。正如您在第一个路径中看到的那样，手动传递ID，并返回来自TheMovieDB的数据。我不想对ID进行硬编码，因此我尝试在第二条路径中使其动态化。

预先填写：

app.get('/comments/', (req, res) => {
    request('https://api.themoviedb.org/3/movie/401478/reviews?api_key={key}', function (error, response, body) {
        console.log('error:', error); // Print the error if one occurred and handle it
        console.log('statusCode:', response && response.statusCode); // Print the response status code if a response was received
        res.send(body)
    });
});

动态：

app.get('/comments/:id', (req, res) => {
const id = req.params.id;
    request('https://api.themoviedb.org/3/movie/' + id +'/reviews?api_key={key}', function (error, response, body) {
        console.log('error:', error); // Print the error if one occurred and handle it
        console.log('statusCode:', response && response.statusCode); // Print the response status code if a response was received
        res.send(body)
    });
});

当我使用预先填写的方法并请求时：

localhost:8000/comments/

我得到了正确的答复（评论+评论）

当我像这样使用动态路线时：

localhost:8000/comments/351286

我收到以下回复：{"status_code":34,"status_message":"The resource you requested could not be found."}

我的代码出了什么问题？

可以找到错误列表here。您应该通过以下方式处理请求：

app.get('/comments/:id', (req, res) => {
const {id} = req.params;
    request('https://api.themoviedb.org/3/movie/' + id +'/reviews?api_key={key}', function (error, response, body) {
        if (error) return error;
        if (!reponse) res.send("No themoviedb API response!");
        else {
            swicth (response.statusCode) {
                case 200:
                    res.send(body);
                    break;
                case 501:
                    res.send("Invalid service: this service does not exist");
                    breal;
                //more status codes...
                default:
                    res.send("Generic error");
            }
        }
    });
});

找不到您请求的资源
