Node.js server-side SDK integration-阿里云帮助中心

This topic describes how to integrate the server-side software development kit (SDK) for Captcha with your Node.js application.

Prerequisites

An AccessKey has been created for your Alibaba Cloud account.
You have downloaded and decompressed the Node.js server-side SDK package.

Install the SDK

Find the client file in the decompressed SDK package.
Import the client package into your server-side project.

After you import the package, you can use the Alibaba Cloud Captcha SDK for Node.js in your server-side project.

Notes

The client package contains the classes for the Alibaba Cloud Captcha server-side SDK.

Initialize IClientProfile

IClientProfile is the interface for interacting with the Alibaba Cloud Captcha server-side. You can use it to perform all SDK operations.

Note

IClientProfile is reusable. Set it as a globally unique object for your application.

var client = new afs.default({
    accessKeyId: "*** Provide your AccessKeyId ***",
    accessKeySecret: "*** Provide your AccessKeySecret ***",
    endpoint: "afs.aliyuncs.com",
    regionId:"cn-hangzhou"
})

Call the Alibaba Cloud Captcha server-side API

After you initialize IClientProfile, call the AuthenticateSigRequest interface. You may also need to develop a handler class for frontend page requests and a method to process the results.

// AuthenticateSigRequest
var data = new afs.AuthenticateSigRequest({
    scene:'xxx',
    sessionId:"xxx",
    sig:"xxx",
    appKey: "xxx",
    token: "xxx",
    remoteIp: "xxx"
})
// AuthenticateSigResponse
var response;
client.authenticateSig(data).then(function(result){response = result;console.log(response)})
