我正在开发一个网站，客户要求提供允许使用 Google 和 Facebook 帐户注册/登录的选项。如何从用户的 Google 个人资料中提取电子邮件地址以存储在数据库中？
这是我的代码。问题是我没有完全获取用户配置文件。相反，我只收到用户名。
try
{
WebClient client = new WebClient();
var urlProfile = "https://www.googleapis.com/oauth2/v1/userinfo?access_token="
+ access_token;
string outputData = client.DownloadString(urlProfile);
GoogleUserOutputData serStatus =
JsonConvert.DeserializeObject<GoogleUserOutputData>(outputData);
if (serStatus != null)
{
return serStatus;
// You will get the user information here.
}
}
catch (Exception ex)
{
//catching the exception
}
return null;
最佳答案
这里是一种用 JavaScript 接收数据(电子邮件等)的方法。最后它显示带有数据的警报。 (您可以将此数据存储在数据库中。)这是一个带有 Google 按钮的完整工作示例。
<html>
<head>
<title>Demo: Getting an email address using the Google+ Sign-in button</title>
<!-- Include the API client and Google+ client. -->
<script src = "https://plus.google.com/js/client:platform.js" async defer></script>
</head>
<body>
<!-- Container with the Sign-In button. -->
<div id="gConnect" class="button">
<button class="g-signin"
data-scope="email"
data-clientid="Your_Client_ID"
data-callback="onSignInCallback"
data-theme="dark"
data-cookiepolicy="single_host_origin">
</button>
<!-- Textarea for outputting data -->
<div id="response" class="hide">
<textarea id="responseContainer" style="width:100%; height:150px"></textarea>
</div>
</div>
</body>
<script>
/**
* Handler for the signin callback triggered after the user selects an account.
*/
function onSignInCallback(resp) {
gapi.client.load('plus', 'v1', apiClientLoaded);
}
/**
* Sets up an API call after the Google API client loads.
*/
function apiClientLoaded() {
gapi.client.plus.people.get({userId: 'me'}).execute(handleEmailResponse);
}
/**
* Response callback for when the API client receives a response.
*
* @param resp The API response object with the user email and profile information.
*/
function handleEmailResponse(resp) {
var primaryEmail;
var name;
var gender;
for (var i=0; i < resp.emails.length; i++) {
if (resp.emails[i].type === 'account')
primaryEmail = resp.emails[i].value;
if (resp.displayName != null)
name = resp.displayName;
gender = resp.gender;
}
document.getElementById('responseContainer').value = 'Primary email: ' +
primaryEmail + '\n\nFull Response:\n' + JSON.stringify(resp);
ShowAlert("Email: "+primaryEmail +" "+"Name: "+ resp.displayName +" "+"Gender: "+gender);
}
</script>
