Before the completion of the home page and search interface, now start to write the rest of the interface.

Access to novel sources

Because the original source of Book Chasing artifact is charged and encrypted, it can only use pirated source, so it is necessary to encapsulate an interface to obtain novel source.
Modify the configuration of app.js file routing middleware to add a route

let sourceRouter = require('./routes/source');
app.use('/source', sourceRouter);

Under routes, create a new source.js

let express = require('express');
let request = require('request');
let common = require('../common/common.json'); // Reference to public documents
let router = express.Router();

/** 
  Access to novel sources
  Return to pirated and genuine sources
  param id {String} Is the home page and search return interface books[i].id
  param n {Number || String}  Using the first source, you can use the default 1
  http://api.zhuishushenqi.com/atoc?view=summary&book=${bookID}
*/
router.get('/', function (req, res, next) {
    if (!req.query.id) {
        res.send(JSON.stringify({ "flag": 0, "msg": "Please introduce ID..." }));
    }
    // req.query.id code escape
    let id = encodeURI(req.query.id);
    request.get(`${common.API}/atoc?view=summary&book=${id}`, function (err, response, body){
        if(err){
            res.send(JSON.stringify({ "flag": 0, "msg": "There is an error in the request..." }));
        }
        
        // Parsing returned data
        body = JSON.parse(body);
        // Determine whether to return content
        if (body.length == 0){
            res.send(JSON.stringify({ "flag": 0, "msg": "I haven't got the source of the novel. Let's change it to another novel" }));
        }

        // The first source is the genuine source, which is charge encrypted, so the second source is selected by default
        let n = parseInt(req.query.n);
        if (isNaN(n) || n == 0){
            n = 1;
        }

        // Determine whether n is greater than the length of source data
        if (n >= body.length){
            res.send(JSON.stringify({ "flag": 0, "msg": "n The parameter value of is incorrect. There is no source" }));
        }else{
            res.send(JSON.stringify({ "flag": 1, "books": body[n], "msg": "OK" }));
        }
    });
});

module.exports = router;

Visit http://localhost : 3000 / source /? Id = 50864bf69dacd30e3a0000014 & n = 3, you can see the data returned to the fourth source.

List of novel articles

Modify the configuration of app.js file routing middleware to add a route

let chapterRouter = require('./routes/chapter');
app.use('/chapter', chapterRouter);

Under routes, create a new chapter.js

let express = require('express');
let request = require('request');
let common = require('../common/common.json'); // Reference to public documents
let router = express.Router();

/** 
  Get a list of novel articles
  Return to the list of novel articles
  param id {String} Is the novel source interface books.id
  http://api.zhuishushenqi.com/atoc/${id}?view=chapters
*/
router.get('/', function (req, res, next) {
    if (!req.query.id){
        res.send(JSON.stringify({ "flag": 0, "msg": "Please introduce ID..." }));
    }
    // req.query.id code escape
    let id = encodeURIComponent(req.query.id);
    request.get(`${common.API}/atoc/${id}?view=chapters`, function (err, response, body) {
        if (err) {
            res.send(JSON.stringify({ "flag": 0, "msg": "There is an error in the request..." }));
        }

        if (body == "wrong param"){
            res.send(JSON.stringify({ "flag": 0, "msg": "Incoming bad ID..." }));
        }else{
            // Parsing returned data
            body = JSON.parse(body);
            if (body.chapters.length > 0) {
                res.send(JSON.stringify({ "flag": 1, "chapters": body.chapters, "msg": "OK" }));
           }
        }
        
    });
});

module.exports = router;

Visit http://localhost : 3000 / chapter /? id = 57416370ccc94e41b41df80cc to see the data. id the id returned by the novel source interface.

The content of the novel

Modify the configuration of app.js file routing middleware to add a route

let articleRouter = require('./routes/article');
app.use('/article', articleRouter);

Create article.js under routes

let express = require('express');
let request = require('request');
let common = require('../common/common.json'); // Reference to public documents
let router = express.Router();

/** 
  Get the content of the novel
  Return to the content of the novel
  param link {String} Is the novel article list interface chapters[0].link
  http://chapter2.zhuishushenqi.com/chapter/${link}
*/
router.get('/', function (req, res, next) {
    if (!req.query.link) {
        res.send(JSON.stringify({ "flag": 0, "msg": "Please introduce link..." }));
    }
    // req.query.link code escape
    let link = encodeURIComponent(req.query.link);
    request.get(`${common.CHAPTER}/chapter/${link}`, function (err, response, body) {
        if (err) {
            res.send(JSON.stringify({ "flag": 0, "msg": "There is an error in the request..." }));
        }

        // Parsing returned data
        body = JSON.parse(body);

        if (body.ok){
            res.send(JSON.stringify({ "flag": 1, "chapter": body.chapter, "msg": "OK" }));
        }else{
            res.send(JSON.stringify({ "flag": 0, "msg": "afferent link Erroneous" }));
        }
    });
});

module.exports = router;

Visit http://localhost:3000/article?link=http://www.69shu.com/txt/1463... You can see the data.

Ranking List

Modify the configuration of app.js file routing middleware to add a route

let rankingRouter = require('./routes/ranking');
app.use('/ranking', rankingRouter);

Create ranking.js under routes

let express = require('express');
let request = require('request');
let common = require('../common/common.json'); // Reference to public documents
let router = express.Router();

/** 
  Get leaderboards
  Back to Leaderboard
  param id {String} If no parameter is passed, all the lists will be obtained. Otherwise, the list will be obtained according to the parameter
  http://api.zhuishushenqi.com/ranking/gender
  http://api.zhuishushenqi.com/ranking/${id}
*/

router.get('/', function (req, res, next) {
    // Get all the lists
    request.get(`${common.API}/ranking/gender`, function (err, response, body) {
        if (err) {
            res.send(JSON.stringify({ "flag": 0, "msg": "There is an error in the request..." }));

Separate visits http://localhost : 3000/ranking / and http://localhost : 3000/ranking/54d43437d47d13ff21cad58b can get the data of the list.
