# Get authInfo

To start Alipay, you need to obtain and generate authInfo from the server first, and developers can call our interface:

GET
https://core.authing.cn/connection/social/alipay/:userPoolId/authinfo
Path Paramter
userPoolId
REQUIRED
 string

User pool ID

200: OK 
{
  "code": 200,
  "message": "Get authinfo successfully",
  "data": "apiname=com.alipay.account.auth&app_id=2018010901722731&app_name=mc&auth_type=AUTHACCOUNT&biz_type=openservice&method=alipay.open.auth.sdk.code.get&pid=2088422236285260&product_id=APP_FAST_LOGIN&scope=RSA8e8e-4888-type=RSA8e-4 -82bdc5786cec & sign = inNShZI0RrLvR% 2F3V10tAQOQTLSmUKNtzbXbmDKVKGXc% 2FCeIhoGqv4hrD4amq4h8ejj9PwAJkToXxLZI% 2FSNQDcABFsrPGagKMpIn7wOBBYKHguOt5gJmG0D305eehmXheosDu4GmhPPpDe3Lks4aWjwswbN2rD2KqqGKOrEtTrXIomc% 2By30F37E2rH8jwo7zeATjY% 2B27qbgu% 2FlGkHg0SwZ1GHs% 2Fxic0xRMilxDRCd% 2BSLYuyQhqBO% 2B6lKXA% 2BZb8N1V5GHWLkC1rpNEKPgfXwU6lWaXJ6JfFKIshPsJYEXRbTtIDUqI5sd8o8Y68MlYf1OlsOKmz24% 2FZRKm% 2Bu2JpVyWpw% 3D% 3D "
}

swift code example:

import Alamofire

let GetAuthInfoUrl = "https://core.authing.cn/connection/social/alipay/<YOUR_USERPOOL_ID>/authinfo"

func loginByAlipay() {

    // Get authInfo
    AF.request(GetAuthInfoUrl).responseString {response in
        let resp = convertToDictionary(text: response.value!)!

        // Authing business status code, 200 means success
        let code = resp["code"]! as! Int
        let message = resp["message"]! as! String
        if code == 200 {
            let authInfo = resp["data"]! as! String
            debugPrint("authInfo: \(authInfo)")

            // Open Alipay
            AlipaySDK().auth_V2(withInfo: authInfo, fromScheme: "authing-alipay", callback: {resp in
                debugPrint(resp)
            })
        } else {
            debugPrint("Message: ", message)
        }
    }
}

# Open Alipay login

Swift sample code:

// Open Alipay
AlipaySDK().auth_V2(withInfo: authInfo, fromScheme: "authing-alipay", callback: {resp in
    debugPrint(resp)
})

The fromSchema here needs to be consistent with the URL Schema in the set URL Types: as shown in the figure below:

# Receive Alipay callback data

You can get Alipay callback data in the following methods (see this Demo (opens new window) for details):

func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>)

Swift sample code:

func parseUrlQueryString(string: String) -> [String:Any] {
    let arr = string.components(separatedBy:"&")
    var data = [String:Any]()
    for row in arr {
        let pairs = row.components(separatedBy:"=")
        data[pairs[0]] = pairs[1]
    }
    return data
}


// schema callback
func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {
    let url = URLContexts.first?.url
    let schema = url!.scheme
    switch schema {
    case AlipayURLSchema:
        AlipaySDK().processAuth_V2Result(url, standbyCallback: {back in
            let response = back!
            let resultStatus = response["resultStatus"] as! String
            let memo = response["memo"]
            let result = response["result"] as! String

            let data = parseUrlQueryString(string: result)
            let success = data["success"]
            let result_code = data["result_code"] as! String
            let auth_code = data["auth_code"] as! String
            let user_id = data["user_id"] as! String
            if resultStatus == "9000" && result_code == "200" {
                // proceed to the next logic
            }
        })
    default:
        debugPrint("???")
    }
}

# Exchange user information

The auth_code obtained in the previous step can be exchanged for user information through the following API:

GET
https://core.authing.cn/connection/social/alipay/:userPoolId/callback
Path Paramter
userPoolId
REQUIRED
 string

User pool ID

200: OK 
{
  id: '5f8ff3f3864c9c62bb76fdb1',
  email: null,
  emailVerified: false,
  unionid:'alipay:2088422236285260',
  openid: null,
  oauth:'{"code":"10000","msg":"Success","avatar":"https://tfs.alipayobjects.com/images/partner/TB1_fGraDXGDuNjmf7YXXctaXXa","city":"Huaihua City" ,"gender":"m","isCertified":"T","isStudentCertified":"F","nickName":"Bob","province":"Hunan Province","userId":"2088422236285260", "userStatus":"T","userType":"2"}',

  lastIP: undefined,

}

Swift code example:

let url = "https://core.authing.cn/connection/social/alipay/\(UserPoolId)/callback?auth_code=\(auth_code)"
AF.request(url).responseString {response in

    // Convert response.value into a string, the example is as follows:
    // ["code": "200", "message": "Obtaining user information successfully", data: ""]
    let resp = convertToDictionary(text: response.value!)!
    let data = resp["data"] as! [String: Any]
    debugPrint("Data: \(data)")
}

# Next Step

Congratulations, you have now accessed the Alipay mobile application login. After obtaining the user information, you can get the login credential token. You can carry this token in subsequent API requests, and then distinguish different users based on this token in the backend interface. For details, see [Verification token](../ ../advanced/verify-jwt-token.md#yan-zheng-authing-qian-fa-de-token).

We also provide React Native SDK, which allows you to quickly access Alipay login in React Native:
