function __construct(){

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？

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：

答案 1 :(得分：5)
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。
答案 2 :(得分：2)
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>

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]);
}
}

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。
