Google Play App信息爬虫

借助开源JS项目https://github.com/facundoolano/google-play-scraper#list

主要有以下几个API

app: Retrieves the full detail of an application.
list: Retrieves a list of applications from one of the collections at Google Play.

API功能

App

1. 根据Google Play 包名获取App的信息

var gplay = require('google-play-scraper');

gplay.app({appId: 'com.google.android.apps.translate'})
  .then(console.log, console.log);

这个并不会在一开始用，因为Google Play的包名一开始并不知道。往往需要先获取到包名，再调用这个API

List

根据分类，国家，排名获取App列表，这个是最常用。

var gplay = require('google-play-scraper');

gplay.list({
    category: gplay.category.GAME_ACTION,
    collection: gplay.collection.TOP_FREE,
    num: 2
  })
  .then(console.log, console.log);

 

我们需要采集的类型和地区有

var categories = new Array(
  gplay.category.EDUCATION,
  gplay.category.WEATHER,
  gplay.category.TOOLS,
  gplay.category.TRAVEL_AND_LOCAL,
  gplay.category.SPORTS,
  gplay.category.SOCIAL,
  gplay.category.NEWS_AND_MAGAZINES,
  gplay.category.LIFESTYLE, 
  gplay.category.HEALTH_AND_FITNESS,
  gplay.category.ENTERTAINMENT, 
  gplay.category.SHOPPING)

地区是：

var counrties = new Array(
  'us',
  'uk',
  'th',
  'in',
  'jp',
)
