如何使用PHP获取带有LinkedIn注册API的电子邮件地址

Question

我从一些关于链接注册的教程中获得了这段代码,但是教程只提供了基本信息.我还需要收到用户的电子邮件......我该怎么做？

这是代码:

auth.php

这是我在likesin上访问表单的链接.

<?php
    session_start();
    $config['base_url']             =   '';
    $config['callback_url']         =   '';
    $config['linkedin_access']      =   '';
    $config['linkedin_secret']      =   '';

    include_once "linkedin.php";

    # First step is to initialize with your consumer key and secret. We'll use an out-of-band oauth_callback
    $linkedin = new LinkedIn($config['linkedin_access'], $config['linkedin_secret'], $config['callback_url'] );
    //$linkedin->debug = true;

    # Now we retrieve a request token. It will be set as $linkedin->request_token
    $linkedin->getRequestToken();
    $_SESSION['requestToken'] = serialize($linkedin->request_token);

    # With a request token in hand, we can generate an authorization URL, which we'll direct the user to
    //echo "Authorization URL: " . $linkedin->generateAuthorizeUrl() . "\n\n";
    header("Location: " . $linkedin->generateAuthorizeUrl()); ?>

demo.php

这是我在注册后获得的脚本.

<?php
    session_start();

    $config['base_url']             =   'http://xxx/linkedin/auth.php';
    $config['callback_url']         =   'http://xxx/linkedin/demo.php';
    $config['linkedin_access']      =   '';
    $config['linkedin_secret']      =   '';

    include_once "linkedin.php";

    # First step is to initialize with your consumer key and secret. We'll use an out-of-band oauth_callback
    $linkedin = new LinkedIn($config['linkedin_access'], $config['linkedin_secret'], $config['callback_url'] );
    //$linkedin->debug = true; if (isset($_REQUEST['oauth_verifier'])){
    $_SESSION['oauth_verifier']     = $_REQUEST['oauth_verifier'];

    $linkedin->request_token    =   unserialize($_SESSION['requestToken']);
    $linkedin->oauth_verifier   =   $_SESSION['oauth_verifier'];
    $linkedin->getAccessToken($_REQUEST['oauth_verifier']);

    $_SESSION['oauth_access_token'] = serialize($linkedin->access_token);
    header("Location: " . $config['callback_url']);
    exit;}   else{
    $linkedin->request_token    =   unserialize($_SESSION['requestToken']);
    $linkedin->oauth_verifier   =   $_SESSION['oauth_verifier'];
    $linkedin->access_token     =   unserialize($_SESSION['oauth_access_token']);}

    # You now have a $linkedin->access_token and can make calls on behalf of the current member
    $xml_response = $linkedin->getProfile("~:(id,first-name,last-name,headline,picture-url)");


    $id = $linkedin->getProfile('~:(id)');
    $fname = $linkedin->getProfile('~:(first-name)');
    $lname = $linkedin->getProfile('~:(last-name)');
    $headline = $linkedin->getProfile('~:(headline)');
    $picture = $linkedin->getProfile('~:(picture-url)');

    $id = trim(strip_tags($id));
    $fname = trim(strip_tags($fname));
    $lname = trim(strip_tags($lname));
    $headline = trim(strip_tags($headline));
    $picture = trim(strip_tags($picture)); ?>

Answer 1

电子邮件地址仅供经过身份验证的用户使用,而不适用于他/她的连接.

1. 在授权您的应用程序时,请确保您已请求用户提供r_emailaddress成员权限.身份验证详细介绍身份验证和授予成员权限.

2. 进行以下GET调用以获取经过身份验证的用户的电子邮件地址:

   GET http://api.linkedin.com/v1/people/~:(email-address)
   

Answer 2

您可以通过api $ this-> userProfileUrl =" https://api.linkedin.com/v1/people/~:(id,first-name,last-name,picture-url,public-profile-url)获取电子邮件地址,电子邮件地址)？oauth2_access_token = ";

但你必须设置范围,如$ oauth-> scope ='r_basicprofile,r_emailaddress'; 使用Oauth https://developer-programs.linkedin.com/documents/profile-api

或者尝试 https://developer.linkedin.com/docs/oauth2

Answer 3

对于搜索v2网址的用户

请按照以下网址

 payload = {
        'grant_type': 'authorization_code',
        'code': token,
        'redirect_uri': s.SOCIAL_AUTH_CALLBACK_URL,
        'client_id': s.LINKED_IN_CLIENT_ID,
        'client_secret': s.LINKED_IN_CLIENT_SECRET
    }

POST "https://www.linkedin.com/oauth/v2/accessToken" 

获取访问令牌

GET "https://api.linkedin.com/v2/me"

获取用户数据在头中发送身份验证令牌

GET "https://api.linkedin.com/v2/emailAddress?q=members&projection=(elements*(handle~))"

获取用户的电子邮件地址。

Answer 4

您可以使用以下 EP 访问linkedin 用户电子邮件地址：

`https://api.linkedin.com/v2/emailAddress?q=members&projection=(elements*(handle~))`

确保您已在库中定义了范围“r_emailaddress”。您可以使用以下 curl 请求来获取数据：

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $Url);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
      'Authorization: Bearer '. $token,
      'X-Restli-Protocol-Version: 2.0.0',
      'Accept: application/json',
      'Content-Type: application/json'
    ));
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_VERBOSE, 1);
    curl_setopt($ch, CURLOPT_HEADER, 1);
    $response = curl_exec($ch);
    $headerSize = curl_getinfo($ch, CURLINFO_HEADER_SIZE);
    $body = substr($response, $headerSize);
    $response_body = json_decode($body,true);

$response_body 将返回以下响应：

Array (
    [elements] => Array
        (
            [0] => Array
                (
                    [handle] => urn:li:emailAddress:123456
                    [handle~] => Array
                        (
                            [emailAddress] => your@email.in
                        )

                )

        )

)
