Linkedin Oauth问题-oauth_verifier [英] Linkedin Oauth Issue - oauth_verifier

问题描述

尝试将我的JSAPI令牌交换为REST Oauth令牌时遇到一些问题( https://developer.linkedin.com/documents/exchange-jsapi-tokens-rest-api-oauth-tokens )

Having some problems trying to exchange my JSAPI tokens for REST Oauth Tokens (https://developer.linkedin.com/documents/exchange-jsapi-tokens-rest-api-oauth-tokens)

我正在使用此库- http://code.google.com/p/oauth-php/-与PECL扩展相反，因为我无法在服务器上安装扩展.

I'm using this library - http://code.google.com/p/oauth-php/ - As opposed to the PECL extension as I'm unable to install extensions onto the server.

似乎有很多类似的问题，但没有一个能真正回答这个问题-如何使用上述库向Linkedin进行身份验证.

There seem to be plenty of similar questions, but none which actually answer the question - How to use the above library to authenticate with Linkedin.

我的代码如下:

    $cookie_name        = "linkedin_oauth_" . $this->_c->linkedin_api_key;
    $credentials_json   = stripslashes($_COOKIE[$cookie_name]);
    $credentials        = json_decode($credentials_json);

    // Get the Access Token + Secret
    $access_token_url = 'https://api.linkedin.com/uas/oauth/accessToken';

    OAuthStore::instance("2Leg", array(
        'consumer_key'      => $this->_c->linkedin_api_key,
        'consumer_secret'   => $this->_c->linkedin_api_secret
    ));

    try {

        $request = new OAuthRequester($access_token_url, 'POST', array(
            'xoauth_oauth2_access_token' => $credentials->access_token
        ));

        $result = $request->doRequest();

    } catch(OAuthException2 $e) {

        print_r($e->getMessage());

    }

catch语句输出:

The catch statement outputs:

Request failed with code 400: oauth_problem=parameter_absent&oauth_parameters_absent=oauth_verifier

如何获取此oauth_verifier?据我了解，如果我已经通过了xoauth_oauth2_access_token，就不需要它了吗?

How do I get this oauth_verifier? It was my understanding that I shouldn't need it if I was passing the xoauth_oauth2_access_token already?

我已经检查了所有变量I.E. $ credentials和$ this-> _ c以及所有变量都正确传递.

I've checked all of the variables I.E. $credentials and $this->_c and all of the variables are passing through correctly.

推荐答案

这实际上是oauth-php库中的错误.该库错误地处理了以xoauth_ *为前缀的参数，并以与处理oauth_ *参数相同的方式对待它们.这违反了OAuth规范，并且大多数(所有?)其他OAuth库都没有此问题.解决方法是执行以下操作:

This is actually a bug in the oauth-php library. The library is incorrectly handling parameters which are prefixed with xoauth_* and treating them the same way it handles oauth_* parameters. This is in violation of the OAuth spec and most (all?) other OAuth libraries don't have this issue. The fix is to do the following:

在文件OAuthRequestSigner.php中，找到以下内容:

Inside the file OAuthRequestSigner.php, find the following:

1)在getAuthorizationHeader函数中，找到显示以下内容的行:

1) inside the getAuthorizationHeader function, find the line which reads:

if (strncmp($name, 'oauth_', 6) == 0 || strncmp($name, 'xoauth_', 7) == 0)

并将其更改为:

if (strncmp($name, 'oauth_', 6) == 0)

2)在函数getQueryString中，找到以下内容:

2) Inside the function getQueryString, find the line which reads:

||  (strncmp($name, 'oauth_', 6) != 0 && strncmp($name, 'xoauth_', 7) != 0))

并将其更改为:

||  (strncmp($name, 'oauth_', 6) != 0)

此后，您所需要做的基本上与您已经在做的相同，如下所示:

After that, all you need to do is essentially the same as you were already doing, which is the following:

try {

    $request = new OAuthRequester($access_token_url, "POST", array('xoauth_oauth2_access_token' => $access_token));

    $result = $request->doRequest();

    var_dump($result);

} catch(OAuthException2 $e) {

    print_r($e->getMessage());

}
