Before always see some examples of micro-channel development, but as a beginner there will be a lot of questions before I can find a lot of posts, but ultimately failed to solve, and now the hands of just a project, summarize the share going to do but can not move the hand of my friends, this is only my personal experience as a Talking (college students), inadequacies also hope you have educated us!
Before the development we need three things, the next will be introduced one by one to prepare three things:
First, we need to apply for a public platform account;
Second, you need a domain name space, that have a space on the network;
Again, we need a website;
A: micro-channel public platform account , how to register online have a very detailed tutorial, please see the venue ;
Then the question is, please review carefully the following figure (for the convenience of explanation, the picture treated):
Here we must talked about the URL and token, according to the official date of the event, here recommend Wan network and Ali cloud launch two years of free cloud hosting and virtual domain, yes, yes that is what we need, and I not in advertising, after all, the party of students, compared to government constraints, can not try to use the free, pulling away, and activities address: http: //www.net.cn/hosting/free/, you can follow it a very simple, not to say, however, be noted that: the free version does not provide telephone service, as since the opening of 60 consecutive days, not for the record, and to resolve binding domain, the virtual machine will be withdrawn and deleted . This compares pit father, after all, there is no free lunch, or buy a domain name it, there is a little more than 20 (the cheapest);
He went to the key areas of:
The above is my own to buy the domain name, the following you can see, Free Web Hosting gift, but can also be used;
Well, ready to work winding down, the thing now is to code;
First of all:
When the developer first submitted verification application, the micro-channel server sends a GET request to fill the URL, and take four parameters (signature, timestamp, nonce, echostr), the developer through the efficacy of the signature (i.e., signature), and to determining the authenticity of the message of the entry.
Thereafter, every time the developer receiving user messages, when micro-channel will also bring the first three parameters (signature, timestamp, nonce) URL, the developer still access developer provided by this provision determination efficacy signature authenticity of the message . Efficacy way for the first time to submit application for verification agreement.
| parameter | description |
|---|---|
| signature | Micro-channel encrypted signature, signature combines a timestamp parameter developer filled token request parameters, nonce parameters. |
| timestamp | Timestamp |
| nonce | random number |
| echostr | Random string |
Developer test signature is performed by the request check (check mode below). If confirmed the GET request to the server from the micro-letter, please return it unchanged echostr content parameters, the access into effect, become a successful developer, or access failure.
Encryption / verification process is as follows: 1. The token, timestamp, nonce three parameters lexicographical sort 2. The three splice into a parameter string string sha1 encrypted string 3. The developer may obtain an encrypted signature comparison, the identifier of the request from the micro-channel so that:

Mainly to see the developer documentation ;
Well, the rest is posted to the server just fine.
