Google客户端API - 缺少需要参数：redirect_uri

Question

所以我按照quickstart指南决定将其分解为一个名为scheduler的类。我正在处理身份验证代码，但我一直得到这个：＆＃34;错误400（OAuth 2错误）错误无效请求缺少所需参数：redirect_uri＆＃34;。

class scheduler{

//The Google Client object
private $googleClient;

//the Google Calendar Service ojbect
private $calendarService;

/*
*   Google Calendar Setup
*
*   This creates a Google Client object so that you may create a Google Calendar object.
*
*/
function __construct(){
    //set the application name
    define("APPLICATION_NAME", "Web client 1");
    //
    define("CREDENTIALS_PATH", "~/scheduler/credentials.json");
    //
    define("CLIENT_SECRET_PATH", __DIR__ . "/scheduler/client_secret.json");
    //
    define("SCOPES", implode(" ", array(Google_Service_Calendar::CALENDAR_READONLY)));

    /*if(php_sapi_name() != "cli"){
        throw new Exception("This application must be run on the command line");    
    }*/

    //create the google client
    $this->googleClient = new Google_Client();

    //setup the client
    $this->googleClient->setApplicationName(APPLICATION_NAME);
    $this->googleClient->setDeveloperKey("AIzaSyBmJLvNdMYuFhVpWalkUdyStrEBoVEayYM");
    $this->googleClient->setScopes(SCOPES);
    $this->googleClient->setAuthConfigFile(CLIENT_SECRET_PATH);
    $this->googleClient->setAccessType("offline");

    //get the credentials file path
    $credentialsPath = expandHomeDirectory(CREDENTIALS_PATH);

    //if the file exists
    if(file_exists($credentialsPath)){

        //get the credentials from the file
        $accessToken = file_get_contents($credentialsPath); 

    }//if it does not
    else{

        //request the authorization url
        $authURL = $this->googleClient->createAuthUrl();
        //print the authorization ulr
        echo "<a href=\"$authURL\">Press Me</a><br /><br />";

        //prompt the user to enter the auth code
        print("Enter authentication code: ");

        //
        $authCode = trim(fgets(STDIN));

        //exchange authorization for an access token
        $accessToken = $this->googleClient->authenticate($authCode);

        //store credentials to disk
        if(!file_exists(dirname($credentialsPath))){
            mkdir(dirname($credentialsPath), 0700, true);   
        }

        //put the contents into the credential files
        file_put_contents($credentialsPath, $accessToken);
    }

    $this->googleClient->setAccessToken($accessToken);

    //refresh token if its expired
    if($this->googleClient->isAccessTokenExpired()){
        $this->googleClient->refreshToken($client->getRefreshToken());

        file_put_contents($credentialsPath, $this->googleClient->getAccessToken()); 
    }
}

我发现问题的原因并没有解决方案。在我的Google Developer Console下，我尝试使用＆＃34; http://localhost/＆＃34;进入授权重定向URI部分。它给了我这个错误＆＃34;抱歉，有一个问题。如果您输入了信息，请检查并重试。否则，问题可能会自行解决，请稍后再回来查看。＆＃34;有没有办法让Google Developer Console接受本地主机服务器的重定向uri？

Answer 1

只需在客户端对象上使用方法setRedirectUri($absoluteUrl)：

$client = new Google_Client();
$client->setRedirectUri('http://' . $_SERVER['HTTP_HOST'] . '/oauth2callback.php');

通过：

https://developers.google.com/api-client-library/php/auth/web-app

Answer 2

我得到了它的工作。我要做的就是回到Google Developer Console并删除我创建的项目。然后在制作一个新项目时，它允许我保存我的localhost网址。发生的问题是当我去添加我的localhost网址到重定向网址时，它会说这不可能。当我在点击创建按钮之前设置重定向网址时，它接受它就好了。

Answer 3

我的问题是我没有在Google Console中初始化URI 解决问题：

1-转到您的项目https://console.cloud.google.com/（从顶部选择项目）

2-搜索“ Google sheet API”以确保已启用

3-在左侧菜单上，单击“凭据”

4-如果您已经创建了“ OAuth 2.0客户端ID”，只需点击“编辑”并添加URI，否则创建新的“ OAuth 2.0客户端ID”

5-记住要重新下载“ OAuth 2.0客户端ID”，就像“ client_secret_XXX.apps.googleusercontent.com”将其重命名为凭据.json并将其设置在您的项目上一样 < / p>

Answer 4

Google的用于Sheet API的“PHP快速入门”文档似乎已在https://developers.google.com/sheets/api/quickstart/php过时。

为了让他们的演示使用PHP 7.2+，我不得不修改一下，而且并不是很清楚发生了什么。以下是其快速入门的评论更新版本，可能对使用Google表格API和PHP时遇到问题的其他人有所帮助。

<?php
/**
 * Updated Google Sheets Quickstart
 *
 * https://developers.google.com/sheets/api/quickstart/php
 */
require __DIR__ . '/vendor/autoload.php';

/**
 * Returns an authorized API client.
 * @return Google_Client the authorized client object
 */
function getClient() {

     // Change this to a secure location where you'll save your config *.json files
     // Make sure it isn't publicly available on the web
    $configPath = getcwd();

    // This get's generated by the script, so don't create it
    $credentialsPath = $configPath . 'credentials.json';

    $client = new Google_Client();

    // Matches the "Application Name" you enter during the "Step 1" wizard
    $client->setApplicationName( 'API App Name' );
    $client->setScopes( Google_Service_Sheets::SPREADSHEETS_READONLY );

    // You need to go through "Step 1" steps to generate this file: https://developers.google.com/sheets/api/quickstart/php
    $client->setAuthConfig( $configPath . 'client_secret.json' );
    $client->setAccessType( 'offline' );

    // This must match the "callback URL" that you enter under "OAuth 2.0 client ID" in the Google APIs console at https://console.developers.google.com/apis/credentials
    $client->setRedirectUri( 'https://' . $_SERVER['HTTP_HOST'] . '/' . basename( __FILE__, '.php' ) );

    // We have a stored credentials file, try using the data from there first
    if ( file_exists( $credentialsPath ) ) {
        $accessToken = json_decode( file_get_contents( $credentialsPath ), true );
    }

    // No stored credentials found, we'll need to request them with OAuth
    else {

        // Request authorization from the user
        $authUrl = $client->createAuthUrl();
        if ( ! isset( $_GET['code'] ) ) {
            header( "Location: $authUrl", true, 302 );
            exit;
        }

        // The authorization code is sent to the callback URL as a GET parameter.
        // We use this "authorization code" to generate an "access token". The
        // "access token" is what's effectively used as a private API key.
        $authCode = $_GET['code'];
        $accessToken = $client->fetchAccessTokenWithAuthCode( $authCode );

        // Create credentials.json if it doesn't already exist (first run)
        if ( ! file_exists( dirname( $credentialsPath ) ) ) {
            mkdir( dirname( $credentialsPath ), 0700, true );
        }

        // Save the $accessToken object to the credentials.json file for re-use
        file_put_contents( $credentialsPath, json_encode( $accessToken ) );
    }

    // Provide client with API access token
    $client->setAccessToken( $accessToken );

    // If the $accessToken is expired then we'll need to refresh it
    if ( $client->isAccessTokenExpired() ) {
        $client->fetchAccessTokenWithRefreshToken( $client->getRefreshToken() );
        file_put_contents( $credentialsPath, json_encode( $client->getAccessToken() ) );
    }

    return $client;
}

// Get the API client and construct the service object.
$client = getClient();
$service = new Google_Service_Sheets( $client );

// Get values from a spreadheet and print
// https://developers.google.com/sheets/api/reference/rest/v4/spreadsheets.values/get
$spreadsheetId = '1BxiMVs0XRA5nFMdKvBdBZjgmUUqptlbs74OgvE2upms';
$range = 'Class Data!A2:E';
$response = $service->spreadsheets_values->get($spreadsheetId, $range);
$values = $response->getValues();

if (empty($values)) {
    print "No data found.\n";
} else {
    print "Name, Major:\n";
    foreach ($values as $row) {
        // Print columns A and E, which correspond to indices 0 and 4.
        printf("%s, %s\n", $row[0], $row[4]);
    }
}

Answer 5

这个答案可能不能完全满足您的需求，但是：

如果您只需要读取表格访问权限，则您只需要一个 Google 服务帐户凭据文件 (credentials.json)。

可以像这样简单地切出示例的令牌检索部分：

<?php
require __DIR__ . '/vendor/autoload.php';

if (php_sapi_name() != 'cli') {
    throw new Exception('This application must be run on the command line.');
}

/**
 * Returns an authorized API client.
 * @return Google_Client the authorized client object
 */
function getClient()
{
    $client = new Google_Client();
    $client->setApplicationName('Google Sheets API PHP Quickstart');
    $client->setScopes(Google_Service_Sheets::SPREADSHEETS_READONLY);
    $client->setAuthConfig('credentials.json');
    $client->setAccessType('offline');
    $client->setPrompt('select_account consent');
    return $client;
}


// Get the API client and construct the service object.
$client = getClient();
$service = new Google_Service_Sheets($client);

// Prints the names and majors of students in a sample spreadsheet:
// https://docs.google.com/spreadsheets/d/1BxiMVs0XRA5nFMdKvBdBZjgmUUqptlbs74OgvE2upms/edit
$spreadsheetId = '1BxiMVs0XRA5nFMdKvBdBZjgmUUqptlbs74OgvE2upms';
$range = 'Class Data!A2:E';
$response = $service->spreadsheets_values->get($spreadsheetId, $range);
$values = $response->getValues();

if (empty($values)) {
    print "No data found.\n";
} else {
    print "Name, Major:\n";
    foreach ($values as $row) {
        // Print columns A and E, which correspond to indices 0 and 4.
        printf("%s, %s\n", $row[0], $row[4]);
    }
}

Google 应该在他们的 IMO 示例中提到这一点。

只需改善@kevinLeary的答案，使代码看起来更具模块化：

<?php

    if (!file_exists(__DIR__ . '/vendor/autoload.php')) {
        throw new Exception(sprintf('Please run "composer require google/apiclient:~2.0" in "%s"', __DIR__));
    }

    require_once __DIR__ . '/vendor/autoload.php';

    $redirect_url = 'http://' . $_SERVER['HTTP_HOST'] . '/mydrive/index.php'; // <--- Change it to your web application path, host will be detected automatically  

    $auth_file = __DIR__ . DIRECTORY_SEPARATOR . 'drive-auth.json'; // <--- Your auth2 settings
    $auth_file = str_replace('\\', '/', $auth_file);

    $configPath = addTrailingSlash(getcwd());

    $app_name = 'MY APP NAME';
    $scopes = [

            ];

    /**

     * @return Google_Client the authorized client object
     */
    function getClient($app_name, $auth_file, $credentials_file, $redirect_url, $scopes = array()) {
        // This get's generated by the script, so don't create it
        $credentialsPath = $credentials_file;

        $client = new Google_Client();

        // Matches the "Application Name" you enter during the "Step 1" wizard
        $client->setApplicationName( $app_name );

        else {

            }

            // The authorization code is sent to the callback URL as a GET parameter.
