尝试获取Google accessToken [英] Trying to Get Google accessToken

问题描述

看起来，无论我做什么，谷歌都竭尽全力阻止我完成这个研究项目。我的项目让我使用Google Spreadsheet作为数据库，并使用该电子表格中的数据执行程序化Google图片搜索，并向最终用户显示一些结果。

设置说明

我已经按照这里的说明开始了： https://github.com/asimlqt/php-google-spreadsheet-client 。我将作曲者下载到我的电脑，然后按照指示此处和这里让Composer将必要的库下载到我的项目中。

编码过程
从那里开始，我尝试复制这个人正在回答他的问题。事实上，这里是我的代码：

 <？php 
需要vendor / autoload.php; 
 // require'/php-google-spreadsheet-client-master\src\Google\Spreadsheet\Autoloader.php'; 
 
使用Google\Spreadsheet\DefaultServiceRequest; 
使用Google\Spreadsheet\ServiceRequestFactory; 
 
 const GOOGLE_CLIENT_ID ='someClientID'; //这里，我只是从我的Google Developers帐户中提取了默认的客户端ID 
 const GOOGLE_CLIENT_EMAIL ='someClientEmail'; //我也在这里使用了默认的客户端电子邮件，直接从Google Developers帐户直接购买
 const GOOGLE_CLIENT_KEY ='someKey'; //我使用了我用于Google自定义搜索引擎的密钥
 const GOOGLE_CLIENT_KEY_PATH ='vendor'\\google\apiclient\examples\key.p12'; //我在我的项目文件夹中搜索了具有关键信息的.p12文件，并在此处使用该路径
 const G_CLIENT_KEY_PW ='notasecret'; //默认（我不知道为什么我需要这样做）
 
 //设置googleClient 
 $ googleClient =新的Google_Client（）; 
 $ googleClient-> setApplicationName（'future-graph-611'）; 
 $ googleClient-> setClientId（GOOGLE_CLIENT_ID）; 
 $ googleClient-> setAssertionCredentials（新Google_Auth_AssertionCredentials（
 GOOGLE_CLIENT_EMAIL，
数组（'https://spreadsheets.google.com/feeds','https://docs.google.com / feeds'），
 file_get_contents（GOOGLE_CLIENT_KEY_PATH），//为什么我不能在这里使用硬编码的GOOGLE_CLIENT_KEY？
 G_CLIENT_KEY_PW 
））; 
 // $ googleClient-> setAccessType（'offline'）; 
 //获取accessToken 
尝试
 {
 $ googleClient-> getAuth（） - > refreshTokenWithAssertion（）; //问题在这里，在这一行
 
 catch（Google_Auth_Exception $例外）
 {
 echo $ exception-> getMessage（）; 
} 
 $ accessToken = json_decode（$ googleClient-> getAccessToken（））; 
 $ accessToken = $ accessToken-> access_token; 
？> 
  

出于某种原因，try块中的语句抛出异常：刷新OAuth2令牌的错误，消息：'{error：invalid_grant}'。

我做错了什么？我还需要做些什么，以便这样做？

解决方案

我想我在这里找到了我的问题的答案： https://github.com/asimlqt/php-google-spreadsheet-client / issues / 24

/ *由于某种原因，它们在 CURLOPT_SSL_VERIFYPEER => true （并通过将该索引设置为 false ）* /

It seems like, no matter what I do, Google is trying its very best to stop me from completing this research project. My project has me using a Google Spreadsheet as a database, and use the data from said spreadsheet to perform a programmatic Google Images search, and display a couple of the results to the end-user.

The setup instructions

I have started with following the instructions here: https://github.com/asimlqt/php-google-spreadsheet-client . I downloaded Composer to my computer, and then follow the instructions here and here to have Composer download the necessary libraries to my project.

The coding process From there, I tried to replicate what this guy was doing in his answer. In fact, here is my code:

<?php
    require "vendor/autoload.php";
    //require '/php-google-spreadsheet-client-master\src\Google\Spreadsheet\Autoloader.php';

    use Google\Spreadsheet\DefaultServiceRequest;
    use Google\Spreadsheet\ServiceRequestFactory;

    const GOOGLE_CLIENT_ID = 'someClientID'; // here, I just pulled the default client ID from my Google Developers account
    const GOOGLE_CLIENT_EMAIL = 'someClientEmail'; // I used the default client email here as well, again, straight from Google Developers account
    const GOOGLE_CLIENT_KEY = 'someKey'; // I used the key that I used for the Google Custom Search Engine 
    const GOOGLE_CLIENT_KEY_PATH = 'vendor\google\apiclient\examples\key.p12'; // I did a search on my project folder for the .p12 file that had the key information, and used that path here
    const G_CLIENT_KEY_PW   = 'notasecret'; // the default (I don't know why I need to do this)

    // setup the googleClient
    $googleClient = new Google_Client();
    $googleClient->setApplicationName('future-graph-611');
    $googleClient->setClientId(GOOGLE_CLIENT_ID);
    $googleClient->setAssertionCredentials(new Google_Auth_AssertionCredentials(
        GOOGLE_CLIENT_EMAIL,
        array('https://spreadsheets.google.com/feeds','https://docs.google.com/feeds'), 
        file_get_contents(GOOGLE_CLIENT_KEY_PATH),  // Why can't I use the hard-coded GOOGLE_CLIENT_KEY here?
        G_CLIENT_KEY_PW
    ));
    //$googleClient->setAccessType('offline');
    // get an accessToken
    try
    {
        $googleClient->getAuth()->refreshTokenWithAssertion();  // the problem is here, on this line
    }
    catch (Google_Auth_Exception $exception)
    {
        echo $exception->getMessage();
    }
    $accessToken = json_decode($googleClient->getAccessToken());
    $accessToken = $accessToken->access_token;
?>

For some reason, the statement in the try block is throwing Exception: Error refreshing the OAuth2 token, message: '{ "error" : "invalid_grant" }' .

What the heck am I doing wrong? What more do I need to do, so that this works??

解决方案

I think I found the answer to my question here: https://github.com/asimlqt/php-google-spreadsheet-client/issues/24

/* They, for some reason, had trouble on the line CURLOPT_SSL_VERIFYPEER => true (and fixed it by setting that index to false) */
