为什么在使用谷歌课堂API时会出现404错误？

Question

我正在用PHP编写一个应用程序，它将连接到我的域名的Google教室。但是，当我尝试使用Google教室API执行任何操作时，会出现以下错误：

Message: Error calling GET https://www.googleapis.com/v1/courses?pageSize=100: (404) Not Found

到目前为止我的代码：

$scopes = array(
  'https://www.googleapis.com/auth/classroom.courses',
  'https://www.googleapis.com/auth/classroom.courses.readonly',
  'https://www.googleapis.com/auth/classroom.rosters',
  'https://www.googleapis.com/auth/classroom.rosters.readonly'
);

$gServiceEmail = "[e-mail]";
$gServiceKey = file_get_contents("../path/to/cert.p12");

$client = new Google_Client();
$gAuth = new Google_Auth_AssertionCredentials(
  $gServiceEmail,
  $scopes,
  $gServiceKey
);

$gAuth->sub = "[e-mail]";
$client->setAssertionCredentials($gAuth);

$service = new Google_Service_Classroom($client);
$results = $service->courses->listCourses();

我已经在谷歌管理控制台的应用编程接口设置中为服务号启用了作用域，并在开发人员控制台中启用了应用编程接口。我哪里做错了？

Answer 1

找不到id为的课程。对于课程列表，请使用courses.list（），如以下示例所示。

$client = getClient();
$service = new Google_Service_Classroom($client);

// Print the first 10 courses the user has access to.
$optParams = array(
  'pageSize' => 10
);
$results = $service->courses->listCourses($optParams);

if (count($results->getCourses()) == 0) {
  print "No courses found.\n";
} else {
  print "Courses:\n";
  foreach ($results->getCourses() as $course) {
    printf("%s (%s)\n", $course->getName(), $course->getId());
  }
}

Answer 2

根据课堂API的文档，我认为您的endpoint是错误的。试着把它改成https://classroom.googleapis.com

样品要求：

GET https://classroom.googleapis.com/v1/courses?pageSize=100&key={YOUR_API_KEY}
