WeChat public platform development--Express delivery inquiry

1) API application

2) Mobile query API



3) Server requirements

4) Intelligent query

5) Effect display

------------------------------------------------ ----------------------------------

1) API application

Express 100 provides query interface API, you need to apply for Key http://www.kuaidi100.com/openapi/applyapi.shtml

The number of queries is limited, 2013-11-19 up to 2000 times/day

One of the application conditions is to provide a link to Express 100. I applied 2 times on the homepage of the website

but failed

2) Mobile query API

Express 100 provides mobile query API, http://www.kuaidi100.com/openapi/mobileapi.shtml

No need to apply for a Key, free; however, the returned result is html, which needs to be parsed

Parse through simple_html_dom.php html, finally got the desired result

<?php 
/*
	快递100 提供的接口，返回html;
	使用 simple_html_dom 解析html，得到快递结果

include("simple_html_dom.php");
function express($company,$code) { 
    
	// get html
	$url = "http://wap.kuaidi100.com/wap_result.jsp?rand=20120517&id=".$company."&fromWeb=null&&postid=".$code;
	$html=file_get_contents($url) or die();

	foreach($dom->find(&#39;p&#39;) as $element) {

?>

3) Server requirement

Express 100 does not support Sina SAE platform, and then tried

a) Mobile MMAE platform, but it does Yes; but MMAE is slow and unstable, so give up

b) Tencent Cloud platform, you get 200 for opening an account, but PHP+mySQL costs almost 200 per month, give up

c) Apply for Baidu Cloud platform, BAE can access Express 100, but BAE does not support Google Translate,

OK, solution, WeChat service program is placed in BAE, Google Translate is placed in SAE,

WeChat uses Google When translating, the command is sent to the WeChat service program (BAE), and the Google translation results are remotely called from BAE (SAE)

After the express call demo is done and the server environment is well established, developing the WeChat program is simple

4) Intelligent query

Express query generally requires the courier and the courier company. Intelligent query is to intelligently match the courier company and find the record when only the courier number is given.
The core of intelligent query is matching strategy, some of which are collected online:

公司名称	单号长度	纯数字	常用
德邦		8-10		Y		1或2开头	
EMS		13		N		开头和结尾二位是字母，中间是数字
