node.js implements encapsulation of WeChat interface
This time I will bring you node.js to implement the encapsulation of the WeChat interface, node.js to implement the encapsulation of the WeChat interface. What are the precautions, the following is a practical case, let's come together take a look.
In everyone’s use of node.js, many people will encounter using node.js to implement WeChat JS-API encapsulated interface operations, and many people still don’t know how to implement it. , the following article will introduce to you the implementation method and code, and those who are interested can learn about it together.
Wechat JS-API interface
Function:
Used to manage and obtain access_token, jsapi_ticket and signature produced by WeChat JSSDK
Installation
npm i wechat_interaction_jsapi
Init
let Jsapi = require("wechat_interaction_jsapi");Usage
WECHAT_APPID, WECHAT_APPSECRET are the developer id and password respectively, which can be found in WeChat Public Platform->Development->Basic Configuration
const jssdk = new Jsapi(WECHAT_APPID, WECHAT_APPSECRET);
1. Get access_token, return the promise object, and the resolve callback returns string
jssdk.getAccessToken().then( re => console.log(re) ).catch(err => console.error(err));
2. Get jsapi_ticket, return the promise object, and the resolve callback returns string
jssdk.getJsApiTicket().then( re => console.log(re) ).catch(err => console.error(err));
3. Obtain the JS-SDK permission verification signature, return the promise object, and the resolve callback returns json
jssdk.getSignPackage(url).then( re => console.log(JSON.stringify(re)) ).catch(err => console.error(err));
Front-end calling method
1. Refer to the official documentation
https://mp.weixin.qq.com/wiki?t=resource/res_main&id=mp1421141115
2. Notes:
(1) Confirm that the whitelist has been configured: WeChat Public Platform->Development->Basic Configuration->ip Whitelist
(2) Confirm that the JS interface security domain name has been configured: WeChat public platform->Settings->Official account configuration->JS interface security domain name
