【中文标题】如何在 php 中使用 Google Fit api 获取步数？【英文标题】：How to get steps count with Google Fit api in php ? 【发布时间】：2015-06-26 20:35:54 【问题描述】：我在使用 Google Api Php Client 和 Google Fit 时遇到问题。
我想得到我一天完成的步数总和。
我找到了a response，但它不起作用（看要点）。
我的php代码：
// Retrive oauth data
$clientData = json_decode(file_get_contents("../Devbook-87e2bafd84e6.json"));
$client_email = $clientData->client_email;
$private_key = $clientData->private_key;
$scopes = array(Google_Service_Fitness::FITNESS_ACTIVITY_READ);
$credentials = new Google_Auth_AssertionCredentials(
$client_email,
$scopes,
$private_key
);
$client = new Google_Client();
$client->setState('offline');
$client->setRedirectUri('urn:ietf:wg:oauth:2.0:oob'); // Used in hybrid flows
$client->setAssertionCredentials($credentials);
if ($client->getAuth()->isAccessTokenExpired())
$client->getAuth()->refreshTokenWithAssertion();
$fitness_service = new Google_Service_Fitness($client);
$dataSources = $fitness_service->users_dataSources;
$dataSets = $fitness_service->users_dataSources_datasets;
$listDataSources = $dataSources->listUsersDataSources("me");
$timezone = "GMT+0100";
$today = date("Y-m-d");
$endTime = strtotime($today.' 00:00:00 '.$timezone);
$startTime = strtotime('-1 day', $endTime);
while($listDataSources->valid())
$dataSourceItem = $listDataSources->next();
if ($dataSourceItem['dataType']['name'] == "com.google.step_count.delta")
$dataStreamId = $dataSourceItem['dataStreamId'];
$listDatasets = $dataSets->get("me", $dataStreamId, $startTime.'000000000'.'-'.$endTime.'000000000');
$step_count = 0;
while($listDatasets->valid())
$dataSet = $listDatasets->next();
$dataSetValues = $dataSet['value'];
if ($dataSetValues && is_array($dataSetValues))
foreach($dataSetValues as $dataSetValue)
$step_count += $dataSetValue['intVal'];
print("STEP: ".$step_count."<br />");
;
这里的问题是它没有进入第一个while循环：$listDataSources->valid() 返回总是false。
我的问题：为什么它返回 false ？我怎样才能获得步骤？
我尝试使用 Oauth Playground (https://www.googleapis.com/fitness/v1/users/me/dataSources/derived:com.google.step_count.delta:com.google.android.gms:estimated_steps) 检索数据，但没有获得任何数据。
我明白了：
"dataType":
"field": [
"name": "steps",
"format": "integer"
],
"name": "com.google.step_count.delta"
,
"application":
"packageName": "com.google.android.gms",
"version": ""
,
"dataStreamId": "derived:com.google.step_count.delta:com.google.android.gms:estimated_steps",
"type": "derived",
"dataStreamName": "estimated_steps"

【参考方案1】：首先要做的是：您使用的设备上是否有任何数据？我犯了这个错误：尝试从根本没有 Google Fit 数据的帐户获取数据。请不要重复我的错误。
我使用了 与您相同的示例，它对我有用。唯一的区别是我对客户端 API 进行了硬编码，如下所示：
$APIKey = '1231231231231231231231231231123123';
$client_id = '12312312312-dkoasodiajsdaosdjh12h1kjakdahs.apps.googleusercontent.com';
$client_secret = '123123123-1231231-123123123';
$redirect_uri = 'http://localhost/fit/code.php';
您的凭据可能存在问题。
你开始你的会议了吗？在上面的代码后添加session_start()。
下面的代码对我有用。适应它，我希望它对你有帮助。

【讨论】：
【参考方案2】：感谢代码，但有错误：
有几个地方调用了 next() 方法，它会跳过循环中的第一项
需要检查项目是否为对象的地方
下面是我的功能。一些要点：
我获取当前和前一天的步数，并将其存储在会话中。我还有一些其他的会话设置。-$GooglefitCode 全局设置在来自 OAuth 的重定向中，使用 'code' 参数。这里的代码在一个名为 pull.php 的脚本中，回调 URL 是 pull_googlefit.php，它只是将代码存储到 $Googlefit 全局中，并且 PHP 是否包含 pull.php。
如果像之前的代码一样传递 OAuth 代码，我不会执行 header() 重定向。我认为他们这样做是为了从显示的 URL 中删除代码/状态参数。我只是在其他地方使用 javascript 擦除 URL。
请参阅有关在代码中获取步数的评论。谷歌陌生，如果你想匹配他们的应用程序，请使用“estimated_steps”。 "merge_step_deltas" 获取实际步数。

Instead, the Fit app does some additional processing on top of the steps.
It estimates steps based on the activity when none are recorded.
