使用 JavaScript 函数处理凭据响应

处理凭据响应

您可以在 data-callback 属性中设置 JavaScript 函数来处理返回的凭据响应。请参阅以下代码段：

<div id="g_id_onload"
     data-client_id="YOUR_GOOGLE_CLIENT_ID"
     data-callback="handleCredentialResponse">
</div>
<script>
  function handleCredentialResponse(response) {
     // decodeJwtResponse() is a custom function defined by you
     // to decode the credential response.
     const responsePayload = decodeJwtResponse(response.credential);

     console.log("ID: " + responsePayload.sub);
     console.log('Full Name: ' + responsePayload.name);
     console.log('Given Name: ' + responsePayload.given_name);
     console.log('Family Name: ' + responsePayload.family_name);
     console.log("Image URL: " + responsePayload.picture);
     console.log("Email: " + responsePayload.email);
  }
</script>

您可以使用适用于您的语言的 JWT 解码库来验证和解码 JWT 凭据。您还应在服务器端验证 Google ID 令牌。
