Question

我刚在代码中遇到问题。尽管经过我的努力，我仍然找不到解决方案。有人可以帮助我。非常感谢你。我试图在Google上找到解决方案，但没有任何解决方案。我希望知道发生了什么以及如何解决此问题

const express = require('express');
const app = express();
const request = require('request');
var serverInfo = {
    application: 'Test',
    startTime: new Date(),
    db: {},
    lastTime: 0,
    last2Time: 0
};
app.use(function(req, res, next) {
    serverInfo.lastTime = new Date();
    if (req.url.indexOf('//INFO//') === 0)
        return res.status(200).json(serverInfo);
    request({
        baseUrl: 'htttp://api.localhost/',
        uri: req.url,
        method: req.method,
        headers: {},
        body: req.body,
        followRedirect: false,
        encoding: 'utf8',
        gzip: true,
        agent: ''
    }, function(error, response, body) {
        if (error) return console.error(error);
        if (response.statusCode === 404)
            return res.status(404).send('Hello World !');
        req.res = response;
        try {
            req.res.body = JSON.parse(body);
        }
        catch (e) {
            console.error(e);
            req.res.body = body;
        }
        next();
        return serverInfo.last2Time = new Date();
    });
});
app.get('/admin', function(req, res, next) {
    res.send('Admin');
});
app.get('*', function(req, res) {
    return res.status(req.res.statusCode).json(req.res.body); //Error here
});
app.listen(process.env.PORT, function() {
    return console.log('Port: ' + process.env.PORT);
});

和我的错误

感谢所有查看此文章的人！

NodeJS TypeError：res.get不是res.json（req.res.body）上的函数；
