Email Verification Code Login

The Auth.signInWithEmail method is used for email verification code login.

const app = cloudbase.init({
  env: "xxxx-yyy",
  region: "ap-shanghai", // Defaults to Shanghai region if not specified
});

const auth = app.auth();

const email = "test@example.com";

// Step 1: When the user clicks to get the verification code, call the following method to send the email verification code, and store verificationInfo globally for use as a parameter in step 3
const verificationInfo = await auth.getVerification({
  email: email,
});

// Step 2: Wait for the user to enter the email verification code on the page
const verificationCode = userInputCode; // 6-digit verification code

// Step 3: After the user enters the verification code, verify the email verification code and log in
await auth.signInWithEmail({
  verificationInfo,
  verificationCode, // Email verification code entered by the user
