No micro-channel access public java

a. Introduction micro-channel public number

1. The number into service, subscription number, applets, corporate micro-channel;
2. When the user public micro-channel number message, will send information to the micro-channel server,
the public micro-channel number to save server administrator specified in rule management platform,
micro-channel server will be based on setting good rule areas and public No. interaction;
3. when the program is to develop their own, hoping to micro-channel server does not process the request,
but the request is pushed to our own program processes the request,
then returns the results to the micro-channel service WeChat server returns the results to the user;

. b development environment to build
1. develop a good program in your computer through the browser can be accessed directly;
another computer is no way to access, we can make these computers are connected
to the same local area network and then access via ip;
2. on the Internet the other person is not see the program that we developed, and starting the program sent to the cloud server;
we need to program needs and micro-channel server to do the docking in the development process,
if the micro-channel server can not find our program there is no way butt, so when developing,
we first need to do within the network penetration;
it penetrates the aim to make our project can be accessed by other computers on the Internet 3. intranet;
network penetration software: peanut shells, nat123, ngrok (free, not very stable)
within the network penetration principle:
4.ngrok: http: //www.ngrok.cc/
1. Download a registered account;
2. tunneled
protocol: http
name: just write;
before set domain: just write;
local port: localhost: 80 (local project access port)
other unwanted fill;
3. copy the tunnel id, start ngrok client;

. c Open Access
1. Develop ready access to
a public number to log micro-channel platform (need to modify the development of "basic configuration);.
b personal account under a lot of features are not available, micro-channel to provide a test account application.
(HTTPS: // mp.weixin.qq.com / -> service number - "development of the document -" began to develop - "No application interface testing);
. c access to micro-channel public platform, developers need to complete the following steps:
HTTPS: // developers .weixin.qq.com / DOC / offiaccount / Basic_Information / Access_Overview.html
1, fill in the server configuration
2, validation server address
3, according to business logic interface documentation
within 2.url network through the url + + project method name name
token: the code requires consistent and;

The relevant code

@RequestMapping("/index")
public String index(HttpServletRequest request) {	
    String signature = request.getParameter("signature");
    String timestamp = request.getParameter("timestamp");
    String nonce = request.getParameter("nonce");
    String echostr = request.getParameter("echostr");
    System.out.println(signature+"\n"+timestamp+"\n"+nonce+"\n"+echostr);   
    if(check(timestamp,nonce,signature,TOKEN)) {
    	 System.out.println("接入成功");
    }else {
    	 System.out.println("接入失败");
    }
    
	return "index";
}

	//1.将token、timestamp、nonce三个参数进行字典序排序   
	  String [] str = {token,timestamp,nonce};
	  Arrays.sort(str);
	  //2）将三个参数字符串拼接成一个字符串进行sha1加密 
	  String strs = str[0]+str[1]+str[2];
	  String mysig= sha1(strs);
	  System.out.println("mysig:---->"+mysig);
	  //3）开发者获得加密后的字符串可与signature对比，标识该请求来源于微信
	 return mysig.equals(signature);
}
