nodejs获取常见疾病数据示例

日常生活中有一些常见的疾病，这个可以通过百度等搜索到，但是如果你要完成一款app或者小程序、网站之类的该如何来获取常见疾病的信息呢？首先想到的是通过爬虫爬取数据，然后整理搜索....其实这种方法还是太曲折了，网上有很多免费的api接口，现在已nodejs为例来看如何获取数据：

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

//配置您申请的appKey和openId
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对应80端口,https 对应443端口，请使用者自己改正
	var servlet="life/commondisease/get";
	var method="post";
	var request_url=domain+servlet;

	var params = {};
	params['appKey']=app_key;
    params['openId']=open_id;

	//变动部分
	params["keyword"]="神经外科";
	params["field"]="department";
	params["highlight"]=1;
	params["pageSize"]=10;
	params["currentPage"]=1;

	request_content(request_url,port,params,method);
}

main();

再以python为例，其实也非常容易实现：

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

import urllib
from urllib import urlencode

#配置您申请的appKey和openId
app_key="***"
open_id="***"

"""
request_url 请求地址
params 请求参数
method 请求方法

"""
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="life/commondisease/get"
    method="post"
    request_url=domain+servlet

    #字典
    params ={}

    params["docName"]=app_key
    params["openId"]=open_id

    #变动部分
    params["keyword"]="神经外科"
    params["field"]="department"
    params["highlight"]=1
    params["pageSize"]=10
    params["currentPage"]=1

    request_content(request_url,params,method)

if __name__ == '__main__':
    main()
