unicloud access alipay development platform

uniCloud Is based on node For the running environment , So you have to connect node Version of SDK, Need to install npm package , because npm Packet size exceeds 10M, So far, , Only Tencent cloud environment can meet the demand .

This is Alipay development platform. SDK Of npm Resources to address , There are installation and usage documents , You can go to find out



Cloud functions can · Use npm Install third party dependencies , So start with cloud functions

Open the terminal in the cloud function directory you need



  initialization npm engineering ( Initialize in the cloud function directory , If there is already package.json The file , Skippable )

npm init -y

Installation dependency ( Install dependency in cloud function directory )

npm install alipay-sdk --save

Key generation ( I choose the certificate mode , This operation depends on the actual development situation )

Information required

1、 Apply private key certificate : Key generated by tool ( Not JAVA Format ,RSA2 Signature type ), Then copy yourself to create one pem Format file )

2、 Apply public key certificate

3、 Alipay public key certificate

4、 Alipay certificate

The four documents are available at https://opendocs.alipay.com/open/291/105971 Know how to operate

Be careful : Apply private key conversion pem Format file , Pay attention to the string format , Never use txt Format , Rename directly pem The idea of similar format . otherwise , Report when using 0D0680A8:asn1 encoding routines:ASN1_CHECK_TLEN:wrong tag error , You can use openSSL Tool generation pem file , Operation document https://opensupport.alipay.com/support/helpcenter/207/201602520381?ant_source=antsupport, Or any other way , Not limited to

When you get the documents above , Put these files directly into the cloud function directory


// Cloud functions are not supported at the moment import How to write it , Only use require Import 
const AlipaySdk = require('alipay-sdk').default;
//node Built in modules 
const fs = require('fs');
const path = require('path');
exports.main = async (event, context) => {
const alipaySdk = new AlipaySdk({
appId: 'xxx',
signType: 'RSA2',
privateKey: fs.readFileSync('./ssl.pem','UTF-8'),// The format I built is UTF-8, The actual development situation depends on the actual filling 
alipayRootCertPath: path.join(__dirname,'./alipayRootCert.crt'),
appCertPath: path.join(__dirname,'./appCertPublicKey.crt'),
alipayPublicCertPath: path.join(__dirname,'./alipayCertPublicKey_RSA2.crt')
return alipaySdk;

Upload the cloud function directly and run the test , If the following message appears , explain SDK Successful import , And it's ready to use


  If you want to use it more SDK, You can move to other documents https://www.yuque.com/chenqiu/alipay-node-sdk/guide
