QR Code Authorization Login

Note: The app in the following process and the accounting system of the central control device need to be associated to be used, otherwise, an error will be reported.

For example, if you use the Tuya Smart app to scan the QR code of your SDK created by the IoT platform, an error will be reported and the session will be invalid.

Flow description

The QR code authorization login function is suitable for APP scanning code to authorize another device to log in to the same account. The device can be a central control device, TV, Pad, etc. The complete authorization process is as follows:

Explanation of the key steps marked in the figure:

Get token

The device requests the interface to obtain the token used in the authorization process, the interface is getQRCodeToken

Generate QR code

Use the obtained token to generate a QR code in a specific format:

The format is: tuyaSmart--qrLogin?token=xxxxxxx

Example:

tuyaSmart--qrLogin?token=AZc72de000-ec00-4000-9e51-b610fc300000

Generate QR code

Display the QR code generated from the above string on the screen of the device;

Get login status

Obtain whether the authorization is successful from the server. If the authorization is successful, the user information will be returned, jump to the application home page, and enter the subsequent operation.

The interface is: QRCodeLogin

Scan QR code

The app scans the QR code on the device, resolves the token in the QR code, and performs the authorization operation

Authorization

Send the parsed QR code to the Server to complete the authorization action.

The authorization interface is QRcodeAuth
