In our daily life, we often encounter the problem of associating related words. That is to say, it is not too difficult to input a word and query related words. But how to accumulate so many words and use good algorithms to link related content is not simple in itself. I think the easiest way is to call the relevant interface, which saves a lot of trouble, and a few lines of python code can be done.

# -*- coding: utf-8 -*-
# flake8: noqa
__author__ = 'wukong'

import urllib
from urllib import urlencode

#Configure the appKey and openId you applied for
app_key="***"
open_id="***"

"""
request_url Request address
params Request parameters
method Request method

"""
def request_content(request_url,params,method):
    params = urlencode(params)
    
    if method and method.lower() =="get":
        f = urllib.urlopen("%s?%s" % (request_url, params))
    else:
        f = urllib.urlopen(request_url, params)
 
    content = f.read()
    print content

   
def main():
    
    domain="http://api.xiaocongjisuan.com/"
    servlet="data/relativeword/mining"
    method="get"
    request_url=domain+servlet
    
    #Dictionaries
    params ={}
    params["appKey"]=app_key
    params["openId"]=open_id
    
    #Change section
    params["keyword"]="preschool education"
    params["degree"]=1
    params["upLimit"]=20
    params["tSort"]="down"
    
    request_content(request_url,params,method)
    
if __name__ == '__main__':
    main()

Of course, it can also be implemented with nodejs

var http = require('http'); 
var qs = require('querystring'); 

//Configure the appKey and openId you applied for
app_key = "***";
open_id = "***";
 
function request_content(request_url,port,params,method){
    
    var path=request_url;
    if(!!params){
        var content = qs.stringify(params);  
        path=request_url+'?' + content;
    }
    
    var options = { 
        port: port,
        path: path,
        method: method
    }; 
    
    if(method.toLowerCase()=='post'){
        options['headers']="Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8";
    }

    var req = http.request(options, function (res) { 
        res.setEncoding('utf8'); 
        res.on('data', function (chunk) { 
            console.log(chunk); 
        }); 
    });  
    
    req.on('error', function (e) { 
        console.log('problem with request: ' + e.message); 
    }); 
    
    req.end();
}

function main(){

    var domain="http://api.xiaocongjisuan.com/";
    var port=8080;//http corresponds to 80 ports, https corresponds to 443 ports, please users correct themselves
    var servlet="data/relativeword/mining";
    var method="get";
    var request_url=domain+servlet;

    var params = {}; 
    params['appKey']=app_key;
    params['openId']=open_id;
    
    //Change section
    params["keyword"]="preschool education";
    params["degree"]=1;
    params["upLimit"]=20;
    params["tSort"]="down";
    
    request_content(request_url,port,params,method);
}

main();

How to use other languages? Click on me to see This is the case. Well, it's actually very simple, and there's no more redundancy.
